The effect of denture adhesive on bite force until denture dislodgement using a gnathometer

Abstract

Purpose: Denture adhesives are used to improve denture retention, stability and function. The purpose of this study was to determine the effect of a cream-type denture adhesive on bite force until denture dislodgement (BFDD) using an improved gnathometer.
Materials and Methods: Twelve denture-wearing patients (six females and six males, mean age: 69 years) were involved in the study. The maximum BFDD of two groups (“no biting pain” and “biting pain”) was measured using a disposable gnathometer before and after denture adhesive application. The standard curve of the gnathometer measurements was produced using a constant load compression testing machine from 10 N to 80 N.
Results: A significant difference was found between the no biting pain group and the biting pain group before the application of denture adhesive (p<0.0001). A notable improvement was observed in BFDD of the biting pain patients after denture adhesive was applied (p<0.0001). No significant difference in BFDD was found in the no biting pain subjects following the application of denture adhesive.
Conclusion: The following conclusions were drawn: 1) Denture adhesive is effective for improving the BFDD of complete denture wearers with biting pain; 2) The gnathometer is useful for measuring the BFDD of complete denture wearers.
