Orthodontics and the temporomandibular joint: where are we now? Part 1. Orthodontic treatment and temporomandibular disorders.

Orthodontists are concerned about the possibility of a link between the treatment they provide and temporomandibular disorders (TMD). The purpose of this article was to review the literature relating malocclusion and orthodontic treatment to problems of the temporomandibular joint (TMJ) and surrounding anatomy. In Part 1, the relationship of orthodontic treatment to TMD is discussed. In Part 2, the relationship of TMD to malocclusion will be addressed.
