## 3 Results
Data analysis identified the first occurrence of a grade of \"Bravo\" in Criteria 1, 4, and 7 over the 10-year follow-up period; the same for both criteria was 4.55% (Table 5). Four of the all-studied restorations (\(n=86\)) had to be replaced at year 5 follow-up because of fracture (failure rate 4.65%; Kaplan-Maier). There are no restorations with bulky, cohesive fractures. Group II demonstrated a satisfactory success rate in terms of color matching and secondary carious lesions during the 5-year follow-up period (Table 5, Figure 1). \begin{table}
