Reprodutibilidade cinemática da mandíbula durante atividades funcionais: abertura e excursão lateral

Abstract

Introduction: Temporomandibular joint (TMJ) is part of the stomatognathic system (SE) and is responsible for sucking, chewing, talking, swallowing. The kinematics is a reliable tool for quantitative evaluation of the movement, which records the trajectories of markers fixed in the body segments and assesses more accurately the human movement. Objective: To a systematic review of the use of kinematics and its application in the TMJ and analyze the kinematic reproducibility of the jaw by means of a three-dimensional tool for functional activity. Material and Methods: The following databases were consulted: BIREME, Capes, PubMed, Science Direct, Scielo and Peter. The search terms used were: "Kinematics", "Temporomandibular Joint", "CentricRelation", "Movements", "Patient-SpecificModeling", "MovementDisorders" in English and Portuguese. After two reviewers independently search, 40 articles were found and after the application of the exclusion criteria, 17 articles were selected for analysis. Participants included in the study underwent four stages of evaluation. As early 2 and 2 after one week. All participants were assessed with RDC / TMD and to exclude any sign or symptom of TMD and clinical condition. They evaluated the movements of opening; Obliquity, rotation, Translation / Antero-posterior, lateral-lateral and vertical movement. Results: 17 articles evaluated and studied three-dimensional dispisitivos demonstrated methodological differences regarding the types of models and variables to be studied. In the opening movement of the present results are promising because it presented ICC considered excellent (0.48 to 1.32). However for the laterality movements it needs a certain amount of caution because the results ranged from "poor" good "reproducibility (0.30 to 0.57). Conclusion: There is no scientific evidence of the clinical application of any of the models of kinematics evaluation of the jaw. The three-dimensional model is reproducible to be opening Intra / Inter days and Intra / Inter evaluators and less reproducible lateral excursions for intra / inter-day and inter evaluators.
