“…A possible link with hormonal changes was suggested. Others have also reported DD in asymptomatic juveniles with prevalence varying with age (mean age 11 years, prevalence 8% 38 rising to 34% in a sample ranging from 6-25 years of age 39 ). However, whilst MRI studies may provide a basis for future research, study designs still require improvement and if links between DD and malocclusion are confi rmed, then the relationship is unlikely to be simple.…”

Objectives To review how occlusion, facial growth, TM disc position and malocclusion may relate to TMD; to review clinical studies investigating TMD pre-and post-orthodontic treatment as well as other studies linking occlusal features with TMD highlighting their limitations; and to make suggestions for improved study designs in the future in order to provide an evidence-base for clinical practice. Design Review article. Methods Electronic databases (MEDLINE and the Cochrane Database of Systematic Reviews) were used to select relevant and frequently cited studies (mean: 28 citations). Citation rate was confi rmed using the Web of Science. Study designs are reviewed and weaknesses discussed. Results Evidence is lacking to suggest static occlusal factors cause TMD. Conclusions Poor study designs have led to much of the controversy over whether occlusal factors (including orthodontics) 'cause' TMD. In order to provide an evidence-base for future clinical practice, suggestions to improve study designs are made.

“…In reality, TMJ DD may be less related to unwanted signs and symptoms than has been previously postulated. 17,27,33 According to the results of this study's skeletal Class III mandibular asymmetrical patients, we can infer that both the frontal mandibular plane angle (which indicates the horizontal asymmetry of the mandible) and the horizontal deviation of the lower incisor (measured from the vertical reference line) indicate the possibility of advanced TMJ DD on the side of mandibular displacement. Another possibility is that both joints may have DD to the same degree when the mandibular asymmetry is not prominent.…”

“…In other words, TMJ DD can be the cause of facial asymmetry. 13,14,26,27 If DD becomes progressive, it might cause bony changes. 28 An irregularly shaped right or left joint can also easily cause a problem.…”

Objective: To investigate the relationship between temporomandibular joint disk displacement (TMJ DD) and facial asymmetry in skeletal Class III patients. Materials and Methods: The subjects comprised 97 skeletal Class III adult patients seeking orthodontic treatment. In addition to the routine lateral and posteroanterior (PA) cephalograms, and regardless of the TMJ status, each subject consented to magnetic resonance imaging (MRI) to evaluate their TMJs. According to MRI readings, subjects were classified into four groups: group 1, bilateral normal disk position; group 2, bilateral DD with or without reduction; group 3, DD more advanced on the right side; and group 4, DD more advanced on the left side. PA and lateral cephalometric variables were analyzed to compare the four groups. Results: When the TMJ DD was more advanced on one side than on the other, the chin point usually deviated to the advanced side. When the TMJ DD status was equal or bilaterally normal, the amount of mandibular deviation was not significant. Conclusions: If a skeletal Class III patient has an asymmetric face, especially in the mandibular region, careful examination is necessary with regard to the status of the TMJ during orthodontic diagnosis and treatment planning.
