[The function of the maxillofacial muscles in dentition defects and periodontal diseases].
Quantitative and qualitative changes of the function of the jaws in dentition defects and periodontal diseases were assessed. Besides dysfunction of every muscle involved, disordered relationships between antagonist and synergic muscles were revealed. Coordinated activity of maxillofacial muscles was 56.4% disordered in class I defects of dentition, 70.5% impaired in class II defects, and 83.3% disordered in class III defects.
