title: [Evaluation of masticatory efficiency of lingualized occlusal complete denture].
abstract: OBJECTIVE
  To compare the masticatory efficiency of lingualized occlusal complete denture with that of semi-anatomical occlusal complete denture.
  
  
  METHODS
  Sixty cases with flat or depressed residual ridges were selected from 2009 to 2011. After randomly divided into two groups, the patients were treated with lingualized and semi-anatomical occlusal complete dentures, respectively. A comparative study of masticatory efficiency was carried out on patients wearing lingualized occlusal complete dentures with those wearing semi-anatomical occlusal complete dentures in different period (1st, 2nd, 3rd, 6th month) after wearing. SAS6.16 software package was used for data analysis.
  
  
  RESULTS
  Once masticatory time or masticatory times were fixed, there was no significant difference between lingualized occlusal dentures and semi-anatomical occlusal complete dentures (P>0.05).
  
  
  CONCLUSIONS
  Lingualized occlusal complete denture can achieve good masticatory efficiency for edentulous patients with flat or depressed residual ridges.
