Evaluation of TMD signals and symptoms in individuals undergoing orthodontic treatment

Abstract

Objetivo: verificar a presença de sinais e sintomas de DTM em indivíduos em tratamento ortodôntico. Material e Métodos: foram avaliados 28 indivíduos que estavam em tratamento ortodôntico na clínica de uma faculdade do estado de São Paulo. Para identificar a presença de DTM foi utilizado o Research Diagnostic Criteria for Temporomandibular Disorders (RDC-TMD). A dor foi avaliada pela Escala Visual Analógica (EVA). A amplitude, dor e ruído durante os movimentos mandibulares, além da dor à palpação de músculos intra e extra orais e cervicais foram aferidos pelo Índice Craniomandibular (ICM). O limiar de dor à pressão foi avaliado por meio de algômetro. Os valores médios e desvio padrão foram obtidos e a análise foi expressa em porcentagem. Resultados: o RDC-TMD demonstrou que a maioria dos indivíduos não apresentaram DTM, que 3,57% apresentaram osteoartrite, 10,71% artralgia, 3,57% deslocamento de disco sem redução, 7% dor miofascial e 14,28% dor miofascial com limitação de abertura; A EVA evidenciou dor média de 1,37 cm (DP=1,4). A média do ICM foi de 0,26 (DP=0,14). O limiar de dor à pressão aferido com algômetro foi de 3,7 (DP=1,7) para o m. temporal anterior e de 3,00 (DP=1,2) para o feixe superficial do m. masseter inferior. Conclusão: foram observados sinais e sintomas de DTM em 39,13% dos indivíduos em tratamento ortodôntico.

Investigation of the association between orthodontic treatment and temporomandibular joint pain and dysfunction in the South Korean population

“…Temporomandibular disorders (TMD) are defined as clinical syndromes characterized by pain and dysfunction of the temporomandibular joint (TMJ) and related masticatory muscles 1. Many factors have been suggested to cause TMD, such as unstable occlusion, psychological factors, and genetic predisposition 2. Among the potential factors, there has been considerable controversy regarding the relationship between occlusal interference and TMD; this has led to questions regarding whether orthodontic treatment is associated with TMD.…”

Criteria for Provisional Restorations Used in Preparation for Comprehensive Orthodontic and Orthopedic Rehabilitation

“…Existing, failed prostheses are replaced. Provisional restorations are made immediately after the removal of low-quality structures and should be fabricated in such a way that the existing problems are addressed (Tanaka et al, 2016;Sarver, 2016; Abdel-Azim et al, 2015) (Fig. 1).…”

“…be restored in case of total orthopedic reconstruction of the dentofacial system (Tanaka et al, 2016;Pinho et al, 2012;Sojka et al, 2015). Before the fabrication of the final restoration, provisional restorations on the occlusal vertical dimension are performed and verified (Silva et al, 2018;Abdel-Azim et al, 2015).…”

“…In planning any orthopedic reconstruction, a prototype of the final restoration is pre-modeled (Tanaka et al, 2016;Pinho et al, 2012;Sojka et al, 2015;Fradeani, 2006). Such modeling may be used to transfer the model into the patient's mouth cavity and to assess the intended result in terms of esthetics and function in the provisional restorations phase (Fig.…”

“…This concept includes a functionally balanced occlusion, smile and face esthetics, temporomandibular joint (TMJ) and periodontium health, the integrity of hard tooth tissues, the maintenance of or increase in the airway volume, and the stability of the results obtained. To achieve a predicted treatment outcome, the close cooperation of an orthodontist with other dental specialists is required (Huang and Chen, 2015;Fradeani, 2006;Pinho et al, 2012;Tanaka et al, 2016;O'Rourke and Taylor, 2008;Sojka et al, 2015;Gorbunkova et al, 2016;Manfredini, 2018).…”
