Summary
Cementing dental prostheses with preheated composite resin shows controversial results compared to traditional resin cement. Further research is needed to establish its superiority for durability and aesthetics.
Area of Science:
- Dental Materials Science
- Prosthodontics
- Biomaterials Engineering
Background:
- Traditional resin cements are standard for dental prosthesis cementation.
- Preheated composite resins offer potential advantages in handling and properties.
- Evidence comparing preheated composite resin cementation to traditional methods is evolving.
Purpose of the Study:
- To systematically review the literature and determine if preheated composite resin cementation is superior to traditional resin cement for dental prostheses.
- To analyze available laboratory studies evaluating this specific cementation technique.
Main Methods:
- A systematic review adhering to PRISMA guidelines was conducted.
- Extensive database searches and gray literature review were performed.
- Nine laboratory studies with low risk of bias were included for qualitative analysis.
Main Results:
- While the degree of conversion was maintained, marginal adaptation was impaired with preheated composites.
- Consensus is lacking regarding microhardness, microtensile/shear strength, failure load, viscosity, film thickness, and color stability.
- Included studies presented a low overall risk of bias.
Conclusions:
- The superiority of preheated composite resin cementation over traditional cements for single-unit prostheses remains controversial.
- Insufficient consensus exists in current literature regarding long-term durability, resistance to masticatory forces, and aesthetic outcomes.
