Abstract

Abstract: Objective: To repaire the posterior tooth defects in the elderly people with CEREC chairside CAD/CAM restorations, and to evaluate the clinical curative effect 1 year after treatment. Methods: A total of 52 posterior teeth from 48 aged patients were selected. Among them, 24 cases were onlays, 18 cases were inlays, and 10 cases were crowns. The inlays/onlays/crowns were designed and manufactured by CEREC chairside CAD/CAM system, and then bonded with resin cement. After 12 months, the patients were followed up. The teeth with restorations were assessed by using the modified USPHS criteria including restorations, tooth, and periodontal. At the same time, the patient's satisfaction was evaluated. Results: In all of the 52 restorations, the success rates of inlay, onlay and crown were 94.4%, 91.7% and 80.0%, respectively; among them, one inlay was fractured, one onlay did not close the edge, one onlay's edge integrity was mild defect, one teeth was fractured, one crown's adjacent relationship was not close, and one crown appeared papillitis. Conclusion: The restorations manufactured by CEREC chairside CAD/CAM system have a good short-term clinical curative effect. It is an effective way to repair the posterior tooth defects in the elderly people.

Key words: elderly, tooth defect, chairside CAD/CAM, inlay, onlay
