Abstract

Aim: Insufficient evidence is available in quantifying the retention between the simplified and conventional non-balanced dentures. The aim of the study was to quantify, compare the maxillary denture retention and patient satisfaction between conventional and simplified removable non-balanced complete dentures. Method: The randomized clinical trial recruited 44 patients (n=22) with definitive criteria. Simplified and conventional non-balanced complete dentures were fabricated for the intervention groups. The denture retention of maxillary complete denture was assessed with dynamometer and patient satisfaction with visual analogue scale. The mean retention of maxillary denture and satisfaction were recorded at 0-,3-, and 6 – month interval. The data were statistically analyzed. (α=.05). Results: The mean ±SD of retention for conventional denture at 0, 3, and 6 months by dynamometer ranged from 121.73 ± 1.64 N to 120.55 ± 1.57 N and
110.77 ±1.45N to 109.59±1.97 N for simplified denture. The mean ±SD of visual analogue score varied between 9.45±0.35 to 7.19± 0.69 for conventional dentures and 8.00 ±1.39 to 6.81±0.82 for simplified dentures. The repeated ANOVA, t-test and post-hoc Bonferroni revealed statistically significant differences between the two types of denture. (P<.05) Conclusion: Numerical retention and satisfaction were higher in conventional non-balanced denture than simplified denture.
