Area of Science:

Dental Materials Science
Prosthodontics

Background:

Fabricating complete denture baseplates requires precise adaptation and dimensional stability.
Polymethyl methacrylate (PMMA) resins commonly used in dentistry exhibit polymerization shrinkage, potentially compromising fit and function.
Current methods may be time-consuming or result in dimensional inaccuracies.

Purpose of the Study:

To describe a novel technique for fabricating multiple acrylic resin baseplates for complete dentures concurrently.
To address and minimize polymerization shrinkage associated with acrylic resin baseplate fabrication.
To enhance the efficiency and accuracy of complete denture construction.

Main Methods:

A technique for simultaneous fabrication of multiple acrylic resin baseplates using master casts was developed.
Denture repair acrylic resin was utilized to mitigate polymerization shrinkage.
Conventional procedures were employed for baseplate stabilization as needed.

Main Results:

The described technique allows for the production of multiple denture baseplates in a single fabrication cycle.
The use of denture repair acrylic resin significantly minimized polymerization shrinkage compared to standard PMMA resins.
The fabricated baseplates demonstrated improved dimensional stability and accuracy.

Conclusions:

The novel technique offers an efficient method for producing multiple, dimensionally stable acrylic resin baseplates for complete dentures.
Minimizing polymerization shrinkage through the use of specialized acrylic resins enhances the quality of denture fabrication.
This approach has the potential to improve clinical outcomes and patient satisfaction in complete denture prosthodontics.
