Objectives: Simplified application and caries preventive features are desired properties for an ideal dental restorative material. Therefore, the aim of this study was to evaluate the clinical performance of a newly developed bioactive alkasite-based resin composite (Cention Forte, Ivoclar Vivadent, Schaan, Liechtenstein) with these properties. Methods: Vital teeth with class I or II restoration need were included in the study. A total of 49 patients received 90 posterior restorations. Extension for retention and beveling were avoided during cavity preparation. The primer (Cention Primer, Ivoclar Vivadent) for alkasite restorative materials was applied prior to restoration placement. Two independent observers made the evaluations using the FDI criteria (scores 1-5) for esthetic, functional, and biological properties. Patients were recalled after three to four weeks (baseline) and one year. Wilcoxon signed rank test was used to evaluate the differences between FDI scores at baseline and after one year. Results: Ninety restorations at baseline and 86 restorations at one year were evaluated. The overall success rate of the restorations was 98.8%, and the overall survival rate was 100% after one year in function. Only one restoration was clinically unacceptable (FDI score 4) due to a small material chip after one year. Conclusions: Quality of the restorations was unaffected in terms of marginal adaptation, marginal discoloration, and secondary caries formation, whereas color and surface luster of the restorations deteriorated slightly over time. No retention loss or tooth fracture was observed.
