Purpose:
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).
Conclusion:
Lingualized occlusal complete denture can achieve good masticatory efficiency for edentulous patients with flat or depressed residual ridges.
