title: [Pilot evaluation of masticatory efficiency and patients' satisfaction in long-centric occlusal pattern complete denture wearers].
abstract: 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 (P<0.05).
  
  
  CONCLUSIONS
  Complete denture with long-centric occlusion can be used to improve the clinical effect of edentulous patients  with severe absorption of residual alveolar rigde.
