Abstract

Background: In the mainstream, dental implants play a significant role. Today’s dentistry focuses on restoring esthetics, shape, occlusion, function, comfort, speech, and overall health. Microleakage at the tooth prosthesis contact has been the subject of numerous investigations in the past. Microleakage at the implant abutment prosthesis contact has received very little attention in the literature. As a result, a study was carried out to
assess microleakage at the implant abutment and prosthesis interface in cemented implant-supported prostheses cemented with three different commercially available luting cements. Materials and Methods: It was an in vitro comparative evaluation research. Atotal of 45 abutment analogue replicas were machined and divided into three groups. The marginal gap was measured with an optical microscope and luted with zinc oxide noneugenol cement, zinc polycarboxylate cement, and zinc phosphate cement. Cemented specimens were immersed in a 0.5% aqueous solution of basic fuchsin solution for 24 h after thermocycling to allow dye penetration. Copings were sectioned longitudinally and microleakage scores were calculated. The Chi-square test was used after the Kruskal–Wallis analysis of variance. The Mann–Whitney U-test was used to compare groups pairwise. Results: Mean microleakage score was least for zinc phosphate cement (1.064 ± 0.43) followed by zinc polycarboxylate cement (1.76 ± 0.41) and most for zinc oxide non-eugenol (2.31 ± 0.76). The results of the study were statistically significant, P < 0.05. Conclusions: It was discovered that all cements had some degree of microleakage. Zinc phosphate cement had a considerably lower mean microleakage score than zinc
oxide non-eugenol cement or zinc polycarboxylate cement. When the microleakage scores of zinc oxide non-eugenol and zinc polycarboxylate cements were examined, the difference was found to be minor, indicating that microleakage is equivalent in both cements.
