[Dimensional accuracy of microwave-cured denture base resin].

Area of Science:

• Dental Materials Science
• Polymer Chemistry

Context:

• Conventional denture base resins often suffer from internal porosity after microwave irradiation.
• Developing improved denture base materials is crucial for enhanced prosthetic fit and longevity.

Purpose:

• To evaluate the dimensional accuracy of a novel microwave-cured denture base resin.
• To compare its accuracy against conventional denture base materials: pour-type, heat-cured, and heat-shock resins.

Summary:

• Microwave-cured denture base resin demonstrated superior dimensional accuracy compared to heat-cured and heat-shock resins.
• Its dimensional accuracy was comparable to that of pour-type resins.
• Cooling methods (slow vs. rapid) did not significantly affect the dimensional accuracy of the microwave-cured resin.

Impact:

• Microwave-cured denture base resin exhibits excellent dimensional stability, making it a clinically valuable material.
• This material may lead to improved denture fabrication and patient outcomes by reducing distortion.
