Comparative Evaluation of Cemented and screw-retained implant-supported single-tooth restorations in the mandibular molar region

Abstract

Background: To evaluate cemented and screw-retained implant-supported single-tooth restorations in the molar mandibular region. Materials & methods: A total of 40 subjects implant-supported restorations were enrolled. A prosthetic rehabilitation of a mandibular molar was done. Debonding of the restoration was analyzed in the cemented-retained restoration group. The student-t test was done. The results were analysed using SPSS software. The significance level was set at P < 0.05. Results: The average rate of complications for cemented-retained restorations was 32.5% and 25% for the screw-retained restorations. Conclusion: In screw-retained restorations the presence of mucositis and peri-implantitis are lower than cemented-retained restorations.
