The Silorane-based Resin Composites: A Review.

Area of Science:

• Dental Materials Science
• Polymer Chemistry
• Restorative Dentistry

Background:

• Methacrylate-based resin composites (MRBC) exhibit significant polymerization shrinkage and stress, leading to clinical issues.
• Silorane-based resin composites (SBRC) were developed to address these shortcomings.
• Understanding SBRC properties is crucial for advancing dental restorative materials.

Purpose of the Study:

• To review research on silorane-based resin composites (SBRC).
• To evaluate SBRC's effectiveness in reducing polymerization shrinkage and contraction stress compared to MRBC.
• To critically appraise the physical, mechanical, and clinical performance of SBRC.

Main Methods:

• Systematic literature review of peer-reviewed dental articles (2003-2015).
• Searches conducted on PubMed and MEDLINE using keywords 'low shrinkage' and 'silorane composites'.
• Inclusion of 70 relevant articles for analysis of SBRC properties and clinical significance.

Main Results:

• Silorane-based resin composites demonstrate reduced polymerization shrinkage and contraction stress.
• SBRC exhibit favorable physical and mechanical properties, including bond strength and marginal adaptation.
• Evidence suggests SBRC can strengthen tooth structure, enhancing clinical performance.

Conclusions:

• Silorane-based resin composites offer a viable alternative to methacrylate-based composites due to lower shrinkage.
• SBRC possess promising physical, mechanical, and clinical characteristics for direct dental restorations.
• Further research and clinical application of SBRC are warranted to fully realize their potential.
