title: Dynamical changes of occlusion and articulation during treatment of mandibular angle fractures.
abstract: Outcomes of mandibular fractures were stated as frequent reason of temporomandibular joint dysfunctions. The objective of this study was to evaluate dynamical changes of occlusion and articulation during treatment of mandibular angle fractures. 12 subjects with mandibular angle fractures underwent analysis of occlusion and articulation in all stages of healing. Findings of investigations were presented in Posselt's and intercondylar axis diagrams, occlusiograms and relative force vs. time graphs. Comparison of results in first day, 1, 3 and 6 months after trauma showed that despite typical process of fragments healing and good fixation but with insufficiently balanced occlusion and posttraumatic discoordination of muscle activity first signs of TMJ articular discs dysfunction were found. Our results confirm the concept that early rehabilitation of mandibular function and occlusion are essential to prevent developing functional disorders of TMJ.
