Abstract:

Objective To study the clinical effect of the functional muscular equal pressure zone on complete denture.Methods Artificial teeth were arranged within the functional muscular equal pressure zone. With this technique 35 complete dentures were made to rehabilitate 35 edentulous patients whose alveolar bones were moderately or seriously absorbed. After three months′ following up, the satisfaction of these patients were investigate. Results After prosthesis treatment, 35 patients enunciated well and the aesthetic effect was favorable. 89 percent of these patients satisfied the retention and the stability of the maxillary denture, and 78 percent satisfied the retention and the stability of the mandibular denture. 79 5 percent of these patients satisfied the mastication efficiency.Conclusion With the technique, the complete denture is fairly stable in patient′s mouth. The technique can enhance the denture′s retention and improve the patient′s mastication efficiency, especially to these whose alveolar bones are moderately or seriously absorbed. Clinically the technique is of high practical value to these edentulous patients who are difficult to be rehabilitated.
