Composite Resin Preheating Techniques for Cementation of Indirect Restorations

Area of Science:

• Dental Materials Science
• Restorative Dentistry

Background:

• Preheating composite resins is employed using various techniques and devices.
• A lack of consensus exists regarding clinical protocols for cementing with preheated composite resins.

Purpose of the Study:

• To identify methods for heating composite resins used in cementing indirect adhesive restorations.
• To determine the benefits and limitations of preheating composite resins.

Main Methods:

• A comprehensive literature search was conducted across multiple databases (PubMed/MEDLINE, Embase, Cochrane, Web of Science, Scopus, LIVIVO).
• Included studies focused on preheating composite resins for indirect restoration cementation, with no restrictions on study type, publication year, or language.
• Data extracted included preheating technique, device, temperature, and warming time.

Main Results:

• 14 articles were included in the final evaluation from an initial 304 identified studies.
• The Calset device was the most frequently reported preheating technique.
• Temperatures of 54°C and 68°C were common, with an average warming time of 5 minutes.

Conclusions:

• Preheating composite resins reduces viscosity, facilitating cementation of indirect restorations.
• Standardization of heating techniques is crucial for consistent clinical results.
• Factors like material temperature, restoration thickness, and resin composition influence procedural outcomes.
