[Pilot evaluation of masticatory efficiency and patients' satisfaction in long-centric occlusal pattern complete denture wearers].

Objective:To assess the masticatory efficiency and patient' satisfaction in long-centric occlusal pattern complete denture wearers.Methods: The anatomic occlusal pattern and long-centric occlusal pattern complete dentures were made for each of 10 edentulous patients with severe alveolar rigde absorption simultaneously using the technique of interchangeable artificial teeth.The order of delivery of different occlusal pattern complete denture was determined according to randomized principle.For each kind of occlusal pattern complete denture,the masticatory efficiency was measured with spectrophotometer after the dentures were worn 2,4,6,8,10 and 12 weeks.A psychometric questionnaire was completed by the patients after wearing the dentures for more than three months and analyzing the patients' rating of the denture satisfaction.Results: No significant differences in masticatory efficiency was found between the long-centric occlusal pattern complete denture wearers and the anatomic occlusal complete denture wearers.The patients' grade of denture satisfaction in long-centric occlusal pattern complete dentures wearers was significantly better than that in anatomic occlusal denture wearers(P0.05).Conclusion: Complete denture with long-centric occlusion can be used to improve the clinical effect of edentulous patients with severe absorption of residual alveolar rigde.
