The treatment of impacted teeth requires an interdisciplinary approach, in which early diagnosis avoids later complications. The frequency of canine retention, especially of the lower canines, has a 0.22 % average in the general population. Case information: A 9.1-year-old patient presented Lepto/Lepto, Lepto; distocclusion due to retrognathism and maxillary protrusion with left condylar asymmetry and preferential chewing on the right side. The patient also presented a structural open bite (Lower Go 78°) hyper-divergence level 4; severe crowding with complete lack of space for tooth 33, and alteration of the eruption corridor of tooth 43. Objective: Stimulate jaw growth to correct distocclusion, stimulate transversal development to gain space and eliminate crowding, and exercise traction on the lower right canine to position it correctly and correct asymmetry. Methods: A series of functional orthopedics devices were used. A Standard Bimler during the first 6 months, subsequently, Simões Network 1 (SN1) to conquer space and initiate traction, followed by the use of an SN11 to correct asymmetry with contra attachment for de-rotation and a lingual S spring. Results: It was possible to obtain incisive contact and align the anteroinferior segment, full space was obtained for tooth 33. Traction of tooth 43 was achieved and thus asymmetry was controlled. Conclusions: Functional orthopedic techniques are an effective form of dental traction that favors treatment from different perspectives. On one hand, it allows to gain space to eliminate crowding. On the other hand, it does not affect neighboring or antagonist teeth because the anchorage is not on the teeth, and it is not necessary to place intraosseous mini-implants. Also, an adequate surgical and functional orthopedic procedure makes it possible to traction the impacted teeth, orienting them to erupt and occupy the correct position in the dental arch.

The position of the condyle can be determined using different diagnostic tools, among which are transcranial X-rays (RT), Cone Beam Computed Tomography (CBCT), and the Condylar Position Indicator (CPI). This study aimed to determine the concordance among the CPI, the CBCT, and the RT as diagnostic methods for determining the condyle position. Materials and method: 32 valid cases, each of which had an RT, a CBCT, and a CPI, were analyzed by three observers. SPSS V. 26.0 program was used to calculate the Kappa trust interval, using the jackknife technique which allows to estimate of the standard error between observers. To evaluate the condylar position using CPI, an AD2 articulator was employed. A Pullinger and Hollender layout was used in the tomographic and transcranial images. Results: The concordance among the three observers for each method resulted in a value of Kappa higher than 0.879. The concordance between CBCT and RT was 0.0627, between CPI and RT it was 0.247, and between CBCT and CPI it was .188. Conclusion: The level of concordance obtained between the three observers with any given diagnostic method was very good, which indicates that the concordance that each observer obtained regarding each diagnostic method is trustworthy. In this study, it is concluded that there is a concordance in the diagnosis regarding the position of the condyle of the tomography with the transcranial radiography. There is no concordance between tomography and CPI. There was also no concordance between the CPI and the transcranial radiography.

The term plagiocephaly means oblique head. Most skull deformities are a result of intrapartum or utero molding but can be caused by congenital torticollis and after birth due to persistent head position of newborns staying in one head position for a long time and abusive use of strollers, car seats, car seats, swings. Its prevalence is growing fast, in 30 years it passes from 1 in each 300 babies in early nineties to 16 to 48 % in 2020. The aim of this paper is bringing the light to some serious conditions of treatment protocols in individuals with plagiocephaly. The skull deformity causes facial asymmetry that are not treatable by orthopedic or orthodontic intra or extra oral appliances, nor orthognathic surgery. Well, despite the fact that the patient or the tutors have to be notified of the facial asymmetry that persists, functional limitations will be presented. In more than 30 years of clinical experience treating these patients it was never sought the 4 first permanent molars and the 4 canines in the same Angle’s Class. In one side can be seen Class 1, but on the other it will be finding class 2 or class 3, the case reported exemplifies it, and the worst, mastication guidance will have to be very carefully done since, in most cases if it is tried to adjust the inferior and superior dental midline the vertical asymmetry of the occlusal plane (minimum vertical dimension) will worsen. Really there is no unique treatment protocol and it has to be considered case by case. It is time to deepen the knowledge in this area since the prevalence is growing. Based on the case reported, non-treated plagiocephaly can bring serious limitations to malocclusion treatment results. Further studies are necessary to a better understanding of the situation plagiocephaly versus malocclusion.

This study aims to present a clinical case and assess the efficacy of the Bimler C Elastic Modeler, a functional orthopedic appliance, in the early treatment of a patient diagnosed with mesiocclusion (mandibular prognathism) based on Bimler and McNamara Cephalometrics. Additionally, we aim to delineate the observed positive changes in facial expression during the course of treatment with this functional orthopedic appliance. The female patient, aged six years and nine months, manifested atypical swallowing, respiratory challenges, and allergic conditions such as rhinitis. Comprehensive examination further revealed facial asymmetry and a smile with lip asymmetry. Intra-oral examination exposed a rightward deviation of the mandible, crossbite, open bite, and mesiocclusion. The proposed intervention encompassed the application of the Bimler Elastic Modeler (BEM) functional orthopedic appliance. The documented treatment duration spanned 12 months, with ongoing monitoring every 2 or 3 months. The treatment, utilizing the BEM functional orthopedic appliance, coupled with exercises and adjustments, improved mandibular and tongue posture, enhancing overall chewing balance. The appliance effectively repositioned the mandible to a more balanced position approaching normocclusion, achieving this without causing pain or discomfort and without the necessity for elastic or constant forces. Given the crucial role of facial expression muscles in these activities, a pronounced enhancement in facial harmony was observed. These affirmative outcomes significantly contributed to heightened patient engagement throughout the treatment process and a concomitant enhancement in patient self-esteem, attributable to the documented aesthetic and functional ameliorations.

The Bimler type A utilizes forces derived from muscles, particularly the tongue, concomitantly, it acts as a systemic, dynamic and functional treatment, Bimler appliances transmit neural excitation throughout the system. The objective of this study was to present a clinical case and demonstrate the efficacy of the functional orthopedic appliance, specifically the Bimler A elastic modeler, in the treatment of a patient diagnosed with distoclusion (prognathism of the maxilla and retrognathism of the mandible) according to Bimler and McNamara cephalometry. The case involved a 9-year and 11-month-old male patient with atypical swallowing, respiratory issues, and allergic conditions such as asthma. Clinical examination and complementary tests revealed a large overjet, a narrow maxilla and mandible, an open bite, and distoclusion (retrognathism). The proposed intervention included the installation of the Bimler Elastic Modeler (BEM), type A. The treatment duration was 12 months, with ongoing monitoring every 2 or 3 months. The comprehensive approach, combining BEM type A, chewing exercises, and occlusal adjustments, resulted in orthopedic changes improved mandibular, tongue, lip, and head posture, as well as enhanced chewing balance. Importantly, the appliance effectively repositioned the mandible into a more balanced, normoccluded position without the need for elastic or constant forces. Beyond the orthodontic changes, the active engagement of facial expression muscles during these activities contributed to an overall improvement in facial harmony, achieving lip seal and notable enhancements in breathing. These positive changes extended to the patient’s daily activities and sports performance. The observed outcomes not only increased the child’s active participation in the treatment but also positively impacted self-esteem, driven by the aesthetic, functional, and psychological improvements experienced.

Planas direct tracks (PDTs) are an alternative treatment based on neuro occlusal rehabilitation (NOR) of various occlusal changes in the primary dentition and in the beginning of mixed dentition. Anterior crossbite is a very common malocclusion during this period. The aim of the present work was to report on Planas direct tracks through a literature review based on neuro-occlusal rehabilitation as a therapy for anterior crossbite (ACB). The search for articles was performed in the databases SciELO (Scientific Electronic Library Online), MEDLINE (National Library of Medicine-USA) and Google Scholar. After searching for articles, 12 studies were listed, however, after evaluating the inclusion and exclusion criteria, only 5 articles remained. The articles found proved to be effective in resolving cases with PDTs based on NOR. PDTs were more suitable for the treatment of anterior crossbite in the primary dentition. The inclination of the tracks was variable, both in the anterior and posterior regions, between 20° and 45° degrees. Three case reports in primary dentition observed ACB correction after 30 days with PDT. As a result, two case reports reported that the treatment of ACB was resolved after 45 days with the effects of clockwise rotation of the mandible and its retropositioning. Another effect observed was the uncrossing of the anterior teeth, presenting an uncrossing of the bite and improvements in facial and postural symmetry. The NOR-based PDT for the case reports presented promoted the resolution of ACB malocclusion, promoting the correction of jaw posture, and in turn, improving the facial and postural symmetry of the mandible.

Use of functional orthopedic appliances (FOA) in the treatment of malocclusion and Temporomandibular Disorders (TMD) has been proved to be effective but there is still questions to be answered like the muscular action of the referred appliances. The aim of this study is checking through a proven protocol of surface electromyography (sEMG) to study muscular action of FOA to check to check if it is correctly manufactured. The appliance studied is a Simões Network 10 – SN10 to treat Class II malocclusion of retrognathia. The sEMG was collected 1 patients with class II malocclusion with retrognathia who belong to a 164 volunteers with malocclusion, in two times T1 before installation of the FOA in mouth, T2 15 minutes after the FOA installation in the mouth. sEMG data of bilateral masseter, bilateral temporal and bilateral suprahyoid muscles using conditioner signals module from Lynx Electronics Ltda with 8 channels, model EMG1000; software AqDAnalysis 4,18 from Lynx Electronics Ltda.; Software Lynx BioInspector 1,8r; passive surface electrodes (Ag/AgCl) from Noraxon Dual Electrodes (USA); dischargeable reference electrodes Kendall Meditrace (Ag/AgCl) – Canada were used for the sEMG measurements. Frequency calibration was 2000 Hz, with 2048 sample by channel and time 1,024 seconds, and filters regulation was 20 Hz and 1000 Hz. With the FOA in the mouth all measurements improved with a more simetrical sEMG in T2 in rest and isometric contraction measurements. The protocol used to check the manufacturing of functional orthopedic appliances using surface EMG proved to be a valid tool in this case report study. Further investigations are needed to confirm this protocol and check if the same happens with other types of functional orthopedics appliances.

The maintenance of the lower level of muscle contraction is fundamental for the development and health of the stomatognathic system (SS). Malocclusion leads to unbalance muscle activity, since Class II treatment is not the most prevalent malocclusion in the general population but is the more frequent to search for treatment in dental offices and the most prevalent skeletal component in the class II malocclusion is the retrognathia this pilot investigation aims to study the effect of rest electric activity of bilateral anterior temporal, masseter and suprahyoid muscle in individuals undergoing class II treatment with functional orthopedic appliance Simões Network 6 (SN6). Surface electromyography recordings of bilateral anterior temporal, masseter and suprahyoid muscle in rest position was obtained before and 8 minutes after the functional appliance insertion in mouth. Results showed improvement of electric muscle activity in rest position and balance of bilateral muscle electric activity in all muscle. Based on the preliminary results it can be conclude that jaw functional orthopedics (JFO) provides alteration of the resting records in the mandibular rest position of the studied muscles, indicating relaxation of the muscles studied and a more symmetrical electric activity. Further studies are necessary for a better understanding of the effects of functional orthopedic appliances in the electric activity of stomatognathic muscle in the mandibular rest position.

The musculature of the face is innervated by cranial nerves, each with a motor, sensory and/or both function. The Facial nerve (FN) is responsible for the motor innervation of the muscles of the face. Some branches of the trigeminal nerve are responsible for the sensory part of the facial muscles and other branches act on the motor part of the chewing muscles. Traumatic Facial Paralysis (TFP) is the one where there was section or traction or compression or ischemia of the FN, in surgery for tumor resection or trauma in general. In this case occurs the nerve’s section in one surgery. Facial Paralysis (FP) can be evaluated subjectively through the House and Brackmann classification scale (HB) [1]. It is considered a chronic FP when it persists for a period longer than 6 months and leaves sequelae, such as synkinesis, contractures and lack of complete innervation of some nerve branches. Some patients who evolve with chronic FP may also evolve with alteration of the occlusal plane. The occlusal plane is the meeting point between the antagonist teeth, plane that is in the final stop of the masticatory cycle. The rehabilitation of this plan is performed according to the needs of each patient, in this case was made through implant prostheses.

One of the goals of malocclusion treatment with Jaw Functional Orthopedics (JFO) is to obtain touch of the inferior incisors against the superior incisors in Determinate Area (DA). It is postulated that this touch would bring better stimuli and consequently faster results. Surface electromyographic study of the muscles was performed in Masseter, Temporal and suprahyoid muscles bilaterally from 159 patients undergoing malocclusion treatment with functional orthopedic appliances (FOA). To record muscle electric activity were used a conditioning signal module from Lynx Electronics Ltda with 8 channels, model EMG1000; software AqDAnalysis 4,18 from Lynx Electronics Ltda.; Software Lynx BioInspector 1,8r; passive surface electrodes (Ag/AgCl) from Noraxon Dual Electrodes (USA); dischargeable reference electrodes Kendall Meditrace (Ag/AgCl) – Canada. Frequency calibration was 2000 Hz, with 2048 sample by channel and time 1,024 seconds, and filters regulation was 20 Hz and 1000 Hz. The results found prove that there is a better electromyographic activity (bilaterally balanced) of the studied muscles when there is touch on DA. Conclusion. Touch in DA improves the neuromuscular response of patients treated with JFO. sEMG is a trustable tool to analyze masticatory muscles function for Diagnosis, Treatment and evaluation post treatment/gained objective.

Knowing that the worldwide prevalence of malocclusion in early childhood is 54 %, we carried out a pilot project in the first half of 2022 at Public Schools in Bento Gonçalves RS, evaluating 1938 children between 2 and 6 years old. The prevalence of malocclusion found was 23 %. Anterior open bite, whether or not accompanied by posterior crossbite, was the most prevalent malocclusion. About 70 % of the children were not breastfed or breastfed for less than 6 months, presenting a non-nutritive sucking habit. Assessing 5 years old children alone, this prevalence rose to 54 %. The results reinforce the need of public health policies that promote and support prolonged breastfeeding, which expand the knowledge of parents or guardians and school staff about the adverse effects caused by the use of pacifiers and baby bottles, with the adoption of transdisciplinary measures for the prevention, interception and treatment of malocclusions in a timely manner.

Micro-rhinic Dysplasia is a common finding in patients who seek for dentofacial correction have several degrees of facial growth commitment and can be associated with another growth syndromes like the Rotation Syndrome, for instance, which may increase the degree of difficulty in corrective treatment of malocclusion. The most challenging malocclusion treatment in an individual with Micro-rhinic Dysplasia is the anterior open bite, mostly when associated with prognathism. The aim of this manuscript is to show through patients records the clinical and cephalometric characteristics of Micro-rhinic Dysplasia alone or associated with other craniofacial growth alterations and their consequences in malocclusion treatment.

Temporomandibular joint (TMJ) ankylosis is one of the most disabling pathological conditions that can occur in the maxillofacial region, often occurring at an early age, limiting growth and causing facial deformity, which significantly affects the quality of life of the individual. The objective of the study was to evaluate the contribution of Jaw Functional Orthopedics (JFO) in TMJ ankylosis after the surgical phase. The case of a 7-year-old female patient diagnosed with bilateral condylar ankylosis (fibrous ankylosis on the right side and bony ankylosis on the left side) is presented. On clinical examination, facial asymmetry, retrognathia, muscle contraction and opening limitation were observed. Treatment consisted of temporalis muscle flap rotation surgery with condylectomy and coronoidectomy, physical therapy, and functional therapy with OFM. The clinical results at 4 months of follow-up suggest significant progress in oral opening and protrusion. The patient showed a high degree of satisfaction with the results obtained. She is currently continuing with the use of orthopedic appliances to correct the sequelae of ankylosis and improve mandibular kinematics.

Posterior crossbite (PCB) is a common malocclusion and its diagnosis must be careful, because only knowing its etiology can determine the treatment plan. The PCB can be dental, skeletal or functional. For each subtype, there is a specific treatment. The aim of this study was to report the treatment of two patients with Skeletal Unilateral Posterior Crossbite. The patients were treated with the same device, a Maurício expander with a Hawley arch. The technique employed, following the Knowledge of Jaw Functional Orthopedics (JFO), proved to be extremely efficient, allowing correction of crossbite malocclusion, mandible centralization, correct dental positioning, restoring conditions so that the growth and development of the patients occurred in a correct and balanced way.

Dentofacial deformities can begin in a very subtle way, which is why there is a need for a well-defined diagnosis. To ascertain whether there is a consensus among specialists regarding the importance of identifying dentofacial deformities in children before they reach six years of age; and to develop and validate a screening tool to assist general dentists so that they can identify signs of craniofacial asymmetry, thereby directing preventive and minimally invasive approaches in children aged three to six years. The guide was created and validated by 37 specialist professionals, masters and doctors. The Delphi technique was used for data analysis, along with the content validity index (CVI) and Cronbach’s alpha. Among the evaluators, 81.08 % had completed their training more than 10 years ago and 78.38% had been working as dentists for more than 10 years; 2.16 % were specialists, 32.16 % had a master's degree and 5.41 % had a doctoral degree. The agreement between the evaluators through the CVI was 100 % and the average Cronbach's alpha was 0.7571, which was considered substantial or acceptable. The clinical semiology guide for detecting dentofacial deformities in children between 3 and 6 years of age was developed and validated.

Satisfactory chewing is performed by an alternating bilateral pattern that depends on occlusal balance, the absence of occlusal interference or premature contacts, stability, good functioning of the temporomandibular joints (TMJs) and neuromuscular maturation. If mandibular functional imbalances occur, discrepancies in maxillomandibular development and future facial asymmetries may occur. The objective of this work was to remove dental interferences that cause anterior and posterior crossbite, as well as those that prevent the good execution of symmetrical lateroprotrusive movements (right side/left side), through occlusal adjustment and subsequent correction of maxillary asymmetry using the device; encapsulated. Clinical case report of a two-year-old female patient, with unilateral crossbite on the right side (anterior/posterior), diagnosed with congenital torticollis, difficulty breastfeeding and difficulty performing alternating lateral movements. with follow-up until the complete deciduous dentition. The treatment was divided into three stages. The first step was to correct the unilateral crossbite (anterior and posterior), on the right side, by making occlusal adjustment using a grid, and later with the addition of Planas Direct Tracks resin. The second stage used an encapsulated device to correct maxillary asymmetry. The third stage was completed after the eruption of the deciduous second molars with the functional analysis of lateral movements plus occlusal adjustments using a grid. Correction of unilateral crossbite (anterior and posterior) on the right side, symmetrization of the maxilla and better execution of lateroprotrusive movements. The results obtained in this case report suggest that the occlusal adjustment removed the dental interferences that caused the anterior/posterior crossbite on the right side; the maxilla was symmetrized with the distalization of sector 63-65, and the removal of dental interferences that prevented lateral movements made it possible to perform lateroprotrusive movements (right/left side) after the complete eruption of the primary teeth.

Sigma is the period of bone remodeling comprised of four phases: activation, resorption, the reverse phase and bone formation. Functional orthopedic appliances (FOA) provoke external stimuli directly at the application area, and indirectly through therapeutic posture change (TPC). The first modifications, which occur approximately 120 days after FOA use, alter the servo system through the central comparator, the occlusal comparator, the outer envelope, and the dental intercom. These changes are repercussions of the sigma period. The Objective is to demonstrate, through photos, the clinical result of the changes of the sigma period from six cases and ratify how important they are for the correct development and growth. The methodology consisted of comparison of the initial photos (intraoral – front and right/left profiles – and extraoral– front and left profile) and after 120 days of a series of six clinical cases of different malocclusions and different ages treated with FOA. After the period of 120 days, it is possible to observe clinical changes in the occlusal comparator and dental intercommunication that translate into improvement of the facial profile and lip sealing observed in the comparison of the photos.

Deep overbite is a malocclusion commonly found in children and difficult to treat, thanks to its instability. Deep overbite is a malocclusion commonly found in children and difficult to treat due to its instability. In deciduous dentition, the most effective treatment is the use of Planas Direct Tracks (PDT), which involves the application of composite resin on the occlusal surfaces of the posterior teeth. Although it is the most effective technique for treating deep bite, it shows a high recurrence rate. To solve this problem, the technique was modified by adding composed resin stops in the lingual face of the upper central incisors. in addition to the traditional tracks on the molars. This study, with the report of 2 clinical cases using the modified PDT, demonstrated that after one year, the treatment was stable and without recurrences, suggesting that the proposed modifications provide more stability than the traditional PDT.

The decrease in magnitude of maxillary dental anomalies at the primordial prevention level by using direct tracks, in addition to occlusal adjustments and masticatory guidance, has several features that can prove to be advantageous. The objective is to demonstrate how continuous in-person and online training performed by specialists in orthodontics and functional maxillary orthopedics of the Regional Hospital of Talca in the Maule region of Chile for odontologists in primary health care can be used to treat occlusopathy in its early stages. The cranial-cervical-mandibular system relies on genetic, environmental and functional factors for its development and the absence of functional stimuli can cause growth disturbances and malocclusions. The major advantage of Planas direct tracks is that it does not require patient collaboration because its basis is in selective wear and restoration with composite resin that acts continuously after construction. Additionally, it is low cost because sophisticated materials are not necessary for its execution and it is a simple technique that can be performed by general dentists, so it is not necessary to be a specialist in orthodontics.

This study evaluates maxillary changes in patients treated with jaw functional orthopedics through artificial intelligence and 3D technology, highlighting its advantages in precision and comfort. Growth changes in children aged 5-12 years after one year of treatment were analyzed using digital models and an intraoral scanner. The results showed significant changes in dental measurements and palatal rugaes, confirming the effectiveness of the treatment. Digital models proved to be superior to plaster models in durability and accuracy. Despite study limitations, such as the small sample size, the findings highlight the importance of 3D technology and suggest future directions for research in the area.

Recently, there has been a rapprochement between disciplines interested in the functioning of the stomatognathic system and ophthalmological alterations, particularly visual function. There is evidence of the relationship between craniofacial anatomical factors and dysfunctions in TMJ biomechanics. Our work investigates the possible relationship between facial asymmetry of mandibular origin and visual acuity in a young adult population. The sample population consisted of 25 subjects (14 female and 11 male) with mandibular asymmetry diagnosed with the Simões Panorogram and the Planas Masticatory Functional Angle to determine the presence or absence of preferential chewing. Likewise, a Snellen chart and an ocular occlude were used to measure visual acuity. To determine the correlation between preferential chewing and the degree of visual acuity, Spearman’s Rho test was used with a 95 % confidence level. The SPSS V.26 statistical program was used. 52 % of the subjects were asymmetrical due to preferential chewing, and 42 % were asymmetric for different reasons. Subjects with unilateral preferential chewing had more excellent visual acuity on the side of asymmetry. Here, we report a positive relationship between subjects who presented asymmetry due to preferential chewing and more excellent ipsilateral visual acuity.

Diagnosis and treatment of mesiocclusion in the deciduous denture can provide balance for the development of occlusion, function, and aesthetics during craniofacial growth and development [1-4]. Jaw Functional Orthopedic (JFO) intervention was performed starting in the deciduous dentition, using the principles of Neuro Occlusal Rehabilitation (NOR) and use of functional orthopedic devices with subsequent follow-up, in two children diagnosed with distinct skeletal Classe III malocclusion. The treatment provided harmonious growth and development between the bone bases of the jaws, compatibility between the middle and lower thirds of the face, improvement in the lateral cephalometric profile, with alteration in the gonial angle, especially in the patient who started treatment at 3 years old of age; thus, avoiding future functional, aesthetic and skeletal complications for the craniofacial complex.

This article presents a case report of a patient with Angle Class III malocclusion and total crossbite, nasal breathing, treated in 11 months with the GUIA PAM III (Postero Anterior Marinho’s) appliance. Early treatment, initiated at 6 years and 8 months repositioned and controlled mandibular growth and corrected the crossbite. Cephalometric measurements taken before and after treatment were used to evaluate the changes resulting from the use of the PAM III appliance proved effective in both stimulating maxillary growth and in increasing maxillary length. According to the results obtained in the initial and final cephalometric measurements, we were able to observe significant changes such as the cephalometric values SNA, which was 84.54° and changed to 86.46°, and 1/.NA, which was 7.72° and changed to 17.14°.

Relapse has always been the main problem in orthodontics. But is it due to the treatment method? Or the age of the patient or the anatomy of the skull? At the examples of some case histories, these questions are considered and hopefully, will contribute a bit to this eternally controversial subject.

Impact of occlusal trauma on periodontal disease: a literature review

Periodontal disease can be defined as a chronic inflammatory process primarily associated with the accumulation of dental biofilm that affects the supporting periodontal and protective tissues of the periodontium, including root cementum, gingiva, alveolar bone, and periodontal ligament. However, evidence indicates that non-microbial factors, such as occlusal trauma, may also contribute to its progression. In this context, the need to investigate the possible correlation between loss of periodontal attachment and the presence of occlusal alterations, particularly those arising from repetitive traumatic loading, is emphasized. The present study aimed to critically analyze the existing scientific literature on the relationship between occlusal trauma and periodontal impairment. A total of twenty-eight articles were included, selected from the SciELO, PubMed, and Google Scholar databases, published between 1999 and 2025, using terms such as occlusal trauma, periodontal disease, inflammatory mediators, and periodontal inflammation. The qualitative analysis aimed to highlight convergences and divergences in the findings, thereby contributing to a deeper understanding of the factors that influence periodontal disease. The study revealed that, although occlusal trauma is not a causative factor of the disease, it exacerbates the destruction of already compromised tissues, highlighting the need for an integrated therapeutic approach for its management.

This case report intends to present a functional appliance designed by the first author, that follow the principles expected for all functional appliances. It is not anchored on teeth. It does not produce mechanical forces and uses tongue and mandible posture change as natural forces. The appliance was used for 24 months, only to sleep. The patient came complaining discomfort with improper occlusion of the teeth and temporomandibular pain. Body balance was evaluated by DIERS and was also altered. It was possible to find out the presence of a unilateral crossbite and alteration on condyle position inside the cavity evaluated by CBCT. After the treatment with CPB (Cranial Posture Balance) appliance associated with osteopathic procedures, the occlusion and the temporomandibular complains were improved.
