Lecture Description

There have been controversies regarding the relation between malocclusion and temporomandibular disorder (TMD). Previous studies reported that specific malocclusion does not seem to cause TMD. However, Class II malocclusion with anterior open bite is frequently observed in TMD patients, which implies TMD may cause clockwise rotation of the mandible and subsequent changes. Therefore, orthodontists must be cautious about the possibility of hidden TMD patients when treating Class II malocclusion with anterior open bite.

For correction of anterior open bite combined with TMD, this talk will present diagnosis of the malocclusion, orthodontic strategy for treatment, monitoring of the changes, and consideration of the muscular factors. A decision on a surgical or non-surgical approach should be made based on an accurate diagnosis, and each method needs a different orthodontic strategy. During orthodontic treatment, orthodontists should detect early favorable or unfavorable changes and the relevance of TMD. Furthermore, it is required for orthodontists to consider muscular factors to obtain predictable and stable outcomes.
