Abstract
Statement of problem
Bilateral balanced occlusion has been advocated over nonbalanced occlusion for improved
removable complete denture stability and function. However, assessments of quality
of life and patient satisfaction studies between the 2 occlusion schemes are lacking.
Purpose
The objective of this parallel randomized control trial was to determine the difference
in quality of life and patient satisfaction between the nonbalanced and bilaterally
balanced occlusal schemes.
Material and methods
Sixty participants were included in the parallel randomized control trial of nonbalanced
and bilaterally balanced complete dentures. Thirty were recruited into each group
with definitive inclusion and exclusion criteria as per the Consolidated Standards
of Reporting Trials (CONSORT) guidelines. Quality of life was estimated from the oral
health quality of life (Oral Health Impact profile) for edentulous patients questionnaire,
and patient satisfaction was analyzed from a visual analog scale. The estimation was
made at 0, 3, and 6 months after denture insertion. The data were statistically analyzed
with the Friedman, Mann-Whitney, and t test (α=.05).
Results
The mean ±standard deviation Oral Health Impact profile score was 60.81 ±8.87 for
nonbalanced dentures and 64.12 ±8.98 for bilaterally balanced dentures. The mean ±standard
deviation visual analog scale score was 2.84 ±0.28 for nonbalanced dentures and 2.90
±0.31 for bilaterally balanced dentures. The Mann-Whitney and t test indicated nonsignificant differences between the 2 groups and at different time
intervals for Oral Health Impact profile and visual analog scale scores (P>.05).
Conclusions
The study detected no significant differences between the 2 occlusal schemes in quality
of life or patient satisfaction.
