Spacer made from a visible light-cured resin for processing denture soft liners.

Area of Science:

• Dental Materials Science
• Prosthodontics

Background:

• Soft lining materials enhance comfort and stability in complete dentures.
• Controlling the thickness and retention of these materials is crucial for clinical success.

Purpose of the Study:

• To introduce and evaluate a light-curing spacer technique for managing soft lining materials in complete dentures.
• To improve the control over thickness and probability of retention of soft lining materials.

Main Methods:

• A spacer fabricated from light-curing denture base material was utilized.
• The denture base resin was packed against the spacer and partially cured.
• The cured spacer was removed to create a uniform space for the soft lining material.

Main Results:

• The light-curing spacer facilitated precise control over the thickness of the soft lining material.
• The spacer prevented displacement, ensuring consistent space for material packing.
• This technique increased the probability of the soft lining material staying in the denture base.

Conclusions:

• The light-curing spacer is an effective tool for managing soft lining materials in complete dentures.
• This method enhances the predictability and stability of soft-lined dentures.
• It offers a reliable approach to achieving uniform thickness and secure retention.
