title: The influence of orthognathic surgery on occlusal force in patients with vertical facial deformities.
abstract: This study utilized bite-force measurements to determine the effect of various orthognathic surgery procedures on occlusal force generation in 42 patients with vertical facial deformities. The results showed that orthognathic surgery produced marked alterations in occlusal force levels which continued to occur up to a year after surgery. Measurements indicated that advancement of the mandible may result in weaker force levels, while bimaxillary surgery for the treatment of a "long face" brings the previously weaker bite force to a more "normal" level.
