Abstract

Aim: This study was aimed to clinically assess the two inlay retained bridges (tub- and inlay-shaped designs) in missing posterior teeth cases. Materials and methods: Thirty cases with missing single posterior tooth were included in the trial and divided into two main groups with a 1:1 allocation ratio (n = 15 for each group). Group I (the control group) received an inlay-retained bridge with inlay design on both abutments. Group II (the intervention group) received an inlay-retained bridge with tub design on both abutments. The inlay-retained bridges were fabricated from monolithic zirconia and bonded using dual-cured self-adhesive resin cement after treating the fitting surfaces mechanically and chemically. The clinical evaluation of the retention, marginal adaptation, and secondary caries occurrence was commenced following the Modified United States Public Health Service (MUSPHS) criteria 12 months after cementation. Results: The results show that the difference was not statistically significant between both groups regarding retention, marginal adaptation, and secondary caries occurrence after 12 months of cementation, with 0.05 statistical significance level and confidence interval of 95%. Conclusion: Within the limitations of this trial, the retention, the marginal adaptation, and the secondary caries for both inlay-retained bridge designs exhibited comparable outcomes. Clinical significance: The use of the inlay-retained bridges with tub design can be superior to the inlay-retained bridges with inlay design regarding the conservation of the tooth structure with the same retention rate, marginal adaptation, and occurrence of secondary caries in missed posterior tooth cases.
