In practice evaluation of a denture adhesive using a gnathometer.

PURPOSE This study measured the extent to which the performance of a maxillary complete denture can be improved with the use of a denture adhesive. This in-practice evaluation assessed both a quantitative measure (force until dislodgement), without and with the adhesive, and patients' perception regarding the use of adhesive. MATERIALS AND METHODS A total of 194 patients (77 men, 117 women) who wore maxillary complete dentures were tested for denture performance both without and with denture adhesive. A simple gnathometer was used. Patient perceptions were also assessed by a questionnaire and analyzed for denture performance as well as the effects on speaking and chewing, fit and comfort, and perceived confidence. RESULTS There was a 63.4% improvement in bite force dislodgement with the use of a denture adhesive. A total of 79.2% of the patients perceived better denture performance (bite force dislodgement) with adhesive use. A total of 55.7% perceived an improvement in speaking and chewing. A total of 56.2% noticed the fit and comfort were better. A total of 63.9% responded that they had improved confidence. CONCLUSIONS Use of a denture adhesive can improve the incisal (or protrusive) biting force for patients who wear a maxillary complete denture. Subjectively, the patients reported an improved perception of denture performance and that the use of adhesive provided greater confidence when using the prosthesis.
