Abstract：Objective To observe the clinical effects of chairside CAD/CAM LavaTM Ultimate composite resin nanoceramics onlays restorations after gingival wall elevation in repairing subgingival defects of molars in elderly patients,providing reference for clinical application. Methods From January 2022 to May 2023,68 patients with a total of 68 molar teeth were selected after gingival wall elevation and restoration with CAD/CAM Ultimate ceramic onlay in the Stomatology Department of Beijing Hospital of Integrated Chinese and Western Medicine. After gingival wall elevation with resin filling,chairside CAD/CAM Ultimate ceramic onlays restorations were applied. At 1 week,6 months,and 1 year after restoration,the clinical effect was evaluated according to the American public health service standards in 7 aspects:edge cohesion,dental integrity,fracture of the restoration,edge coloring,gingival health,restoration retention,and secondary caries in A,B,and C grades. Results One week post-operation,there were no lost follow-ups. The onlays in all seven aspects were evaluated as Grade A in all 68 cases. At 6 months post-operation,one case was lost to follow-up,leaving 65 cases evaluated as Grade A. In one case,the onlay fell off,and after re-adhesion,no loss was observed. One case exhibited mild gingival inflammation. After 12 months post-operation,there were 2 additional cases lost to follow-up. Among the remaining 63 cases,evaluations showed Grade A ratings. Two cases exhibited mild gingival inflammation. Marginal integrity,tooth integrity,marginal discoloration,restoration retention and absence of secondary caries were all well maintained. The success rate at 12 months post-repair was 92.6％ (63/68). Conclusion For elderly patients with subgingival defects on molars,CAD/CAM Ultimate ceramic onlays restorations after gingival wall elevation offer advantages of high restoration success rates,precision,efficiency,convenience and rapid application,making them suitable for clinical promotion and application.
