Clinical Relevance

The clinical behavior of pure ormocer composite is reliable when used in class II restorations after 24 months of evaluation.

SUMMARY
Objective:

The aim of this study was to evaluate the clinical performance of class II restorations made using pure ormocer and methacrylate composites in a period of 24 months, using a split-mouth double-blinded randomized design.

Methods and Materials:

Thirty patients received two class II restorations (n=60) performed with different composites: GrandioSO (methacrylate, nanohybrid) and Admira Fusion (pure ormocer, nanohybrid). The universal adhesive system (Futurabond M+) was applied in all restorations using the self-etching mode. The composites were placed by the incremental technique. The restorations were evaluated using the FDI World Dental Federation criteria after 7 days and 6, 12, and 24 months postoperatively.

Results:

After 24 months, 23 patients attended the recall and 46 restorations were evaluated. Fisher's statistical analysis (5%) showed no difference between the materials. One pure ormocer restoration and one methacrylate restoration presented small fractures. Only one tooth suffered a fracture of the remaining tooth structure. Admira Fusion presented, respectively, 100%, 95.66%, and 100% of acceptable performance in general scores for esthetic, functional, and biological properties. GrandioSO presented, respectively, 100%, 91.31%, and 95.66% of acceptable performance in the same scores.

Conclusion:

After 24-month follow-up, nonsignificant differences between the tested composites was detected. Both materials provided acceptable clinical performance in class II restorations.
