Clinical comparision of restoring posterior teeth with indirect resin inlays and all-ceramic inlays for three years

Objective: To evaluate the clinical performance and inlays in restoring the posterior teeth.Methods: 50 posterior teeth were res tored with Ceramage inlays,and 46 posterior teeth were restored with Vita mark II inlays.All restorations were evaluated immediately,after 1 year and 3 years,according to modified USPHS parameters.Results: There was no significant difference in marginal discoloration,marginal sealability,and secondary carries between these two groups(P 0.05).The Ceramage inlays showed a significant performance in the color matching and resisting fracture than Vita mark II inlays(P 0.05).The achievement ratio of indirect resin inlays is 95 percent,and the achievement ratio of all-ceramic inlays is 73.7 percent.Conclusion: Indirect resin inlays can be suitable for eldlers with specifical requirement.
