Compatibility of denture cleansers with some new self curing denture base materials

Area of Science:

• Dental Materials Science
• Prosthodontics
• Biomaterials Wear

Background:

• Denture base materials undergo abrasion during normal function and cleaning.
• Specific denture cleansing regimens can exacerbate material wear.
• Evaluating the abrasion resistance of novel denture base materials is crucial for clinical longevity.

Purpose of the Study:

• To assess the abrasion resistance of two new acrylic resin denture base materials.
• To compare the wear caused by different denture cleansing regimens.
• To identify which cleansing agents contribute most to material loss.

Main Methods:

• Two novel acrylic resin materials (pour type and compression moulding) were tested.
• Mechanical brushing simulations were performed using various denture cleansers.
• Weight loss was measured to quantify abrasion.

Main Results:

• Both new acrylic resin materials exhibited comparable abrasion resistance.
• Significant weight loss was observed when using one of the paste denture cleansers.
• The type of denture cleanser significantly influenced the degree of abrasion.

Conclusions:

• The tested novel acrylic resins demonstrate similar durability against mechanical abrasion.
• Certain paste denture cleansers pose a higher risk of wear to acrylic denture bases.
• Material selection and appropriate denture hygiene practices are important to minimize wear.
