Objective assessment of denture adhesive effects on masticatory function in removable partial denture wearers.

Area of Science:

• Dental Science
• Prosthodontics
• Biomaterials

Background:

• Limited clinical research exists on the impact of denture adhesives (DA) for removable partial denture (RPD) users.
• Extensive tooth loss presents challenges for RPD wearers, affecting masticatory function.

Purpose of the Study:

• To evaluate the efficacy of DA in improving masticatory function among RPD wearers.
• To assess the impact of DA on masticatory performance (MP) and maximum occlusal force (MOF).

Main Methods:

• A 12-week clinical trial involving RPD wearers using cream-type DA daily.
• Measurement of MOF and MP at baseline, 1 week, and 12 weeks post-intervention.
• Analysis of oral tissue conditions and exploration of factors influencing MP changes.

Main Results:

• Significant improvements in RPD retention (98.4%) and stability (90.2%) were observed with DA use.
• Both MOF and MP showed statistically significant improvements over the 12-week period (P<.001).
• Participants with poorer baseline MP and those with problematic or metal-based dentures reported greater benefits.

Conclusions:

• Denture adhesive effectively enhances RPD retention and stability in individuals with extensive tooth loss.
• DA use leads to significant improvements in masticatory function and performance.
• DA is a beneficial adjunct for RPD wearers seeking to improve their chewing efficiency.
