Abstract:
Objective :To explore the therapeutic efficacy of chairside CEREC all-ceramic restorations in children with first permanent molars with severe defects and to summarize the clinical methods and procedures.
Methods: Forty teeth of 7-15 years old thirty-four children with first permanent molars with severe defects were selected. After careful tooth preparation, a total of 40 all-ceramic restorations (8 inlays, 32 onlays) were designed and manufactured using the CEREC 3D system, and all prostheses were bonded with composite resin cement. Immediately after treatment and after 24 months, the subjective satisfaction of the patients was assessed. The clinical efficacy was analyzed using modified USPHS criteria at 12 months and 24 months. Evaluations included secondary caries, marginal adaptation, surface texture, color matching, fracture, anatomical form, adjacency relationship and gingival health.
Results : For the 40 all-ceramic restorations of the first permanent molars, after 24 months, 100% of the teeth were grade A for secondary caries, surface texture and fracture of the prosthesis, and 85% of the teeth were up to grade A for the other indexes at 12 and 24 months. There were no significant differences (P > 0.05) between 12 months and 24 months. Immediately after treatment and after 24 months, the subjective satisfaction of the patients was greater than 94%.
Conclusion :Application of the CEREC 3D system had a clear curative effect and resulted in high satisfaction in the repair of permanent molars with severe defects in children.
