Sažetak
The aim of this study was to determine the differences in clinical performance between materials for indirect composite restorations based on Ormocer (Admira) and nano-hybrid composite resin (Grandio), both at baseline and 36 months after placement. Modified USPHS criteria were used to analyse the degree of quality. Marginal integrity was assessed 36 months after placement, whereupon the restorations fabricated from Grandio achieved an Alpha 1 score of 70.7% and an Alpha 2 score of 29.3%. The Wilcoxon test revealed a statistically significant difference in the evaluation of marginal integrity (p=0.003), anatomic form of the marginal step (p=0.025) and discoloration of the margins (p=0.014) at baseline and after 36 months. For Admira, the Wilcoxon test showed statistically significant differences in the evaluation of surface texture (p=0, 025), anatomic form of complete surface (p=0, 034), anatomic form of marginal step (p=0, 008), marginal integrity (p=0, 002) and discoloration of the margins (p= 0, 008) at baseline and after 36 months. According to the number of restorations awarded the Alpha 1 score (excellent), the overall success rates for marginal integrity was 70.7% for Grandio and 71.8% for Admira, both evaluated 36 months after placement. Results have shown that the indirect restorations were acceptable after a period of 36 months, which indicates a 100% success rate. Over a period of 36 months years, no statistically significant differences have been noted between the two materials clinically tested: the nano-hybrid composite resin Grandio, and the Ormocer composite Admira. Indirect composite resin restorations represent a good therapy choice for severely damaged teeth.
