Abstract

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 confirmed 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.
