The influence of selective grinding on the thickness discrimination threshold of patients wearing complete dentures.
The influence of selective grinding on the ability of patients wearing complete dentures to discriminate thicknesses occlusally was evaluated. The study included two groups of white Caucasian patients, matched for age, sex and duration of edentulism; 12 wearing traditional complete dentures and 12 wearing maxillary complete denture and mandibular implant-retained overdenture (MIR-OVD). The ability to discriminate thickness was evaluated before and after selective grinding. In both groups, sensitivity improved after selective grinding. Subjects wearing MIR-OVD showed a better ability to discriminate thickness than those rehabilitated with traditional complete dentures. The thickness discrimination threshold might be a suitable method to evaluate complete dentures fit.
