Summary
Denture adhesives enhance the dislodgement forces of maxillary complete dentures, though effectiveness varies between products. Two measurement devices showed poor agreement but are individually useful for research and clinical practice.
Area of Science:
- Dental materials science
- Biomechanical engineering
Background:
- Complete denture stability is crucial for patient satisfaction and function.
- Denture adhesives are commonly used to improve denture retention and chewing efficiency.
- Quantifying the mechanical forces affecting denture dislodgement is essential for evaluating adhesive efficacy.
Purpose of the Study:
- To evaluate the impact of four distinct denture adhesives on the dislodgement forces of maxillary complete dentures.
- To compare the incisal dislodgement forces measured by two different devices.
- To assess the effectiveness of various denture adhesives in enhancing denture stability.
Main Methods:
- 12 complete maxillary denture wearers participated in the study.
- Four commercial denture adhesives (Super Corega®, Corega Ultra®, Super Corega Powder®, Fittydent Cationic®) were tested.
- An electronic and disposable gnathodynamometer measured dislodgement forces at incisal and premolar sites, with and without adhesives.
Main Results:
- Statistical analysis (ANOVA) revealed significant differences in dislodgement forces based on the type of adhesive, denture type, and biting site (p < 0.05).
- Both measurement devices indicated significant differences between adhesives, denture types, and biting sites.
- Bland-Altman and Mountain plots showed poor agreement between the two measurement devices.
Conclusions:
- Denture adhesives demonstrably increase maxillary complete denture dislodgement forces, with notable variations among the tested products.
- While the two measurement devices exhibit limited agreement, each is considered valuable for assessing dislodgement forces in both clinical and research settings.
- The findings suggest that the choice of denture adhesive can influence denture stability, and appropriate measurement tools are necessary for accurate evaluation.
