Summary
This study shows that a new denture adhesive significantly improves maximum bite force until denture dislodgement (BFDD) for up to six hours in complete denture wearers.
Area of Science:
- Dental Materials Science
- Prosthodontics
- Biomechanical Engineering
Background:
- Complete dentures can affect chewing efficiency and stability.
- Denture adhesives are commonly used to enhance denture retention and patient comfort.
- Quantifying the impact of adhesives on functional parameters like bite force is crucial.
Purpose of the Study:
- To evaluate the efficacy of a novel denture adhesive.
- To determine its effect on maximum bite force until denture dislodgement (BFDD).
- To assess the duration of the adhesive's effect over a six-hour period.
Main Methods:
- A study involving 15 complete denture wearers (mean age 64).
- BFDD measurements were taken using a gnathometer at baseline, and at 1, 2, 4, and 6 hours post-application.
- Measurements were conducted with both existing and new dentures, with and without the new adhesive.
Main Results:
- A statistically significant increase in BFDD was observed with adhesive use across all time points for both denture types (p=0.003 for existing, p=0.05 for new).
- Mean BFDD increased from baseline (1.54-3.20 units) to 6 hours (3.99-4.60 units).
- The positive effect of the denture adhesive on BFDD was sustained for up to 6 hours.
Conclusions:
- The tested denture adhesive effectively enhances maximum bite force until denture dislodgement.
- This improvement in functional stability is maintained for at least six hours post-application.
- The findings support the use of this denture adhesive for improving chewing function in complete denture wearers.
