Clinical outcome of implant-supported all-ceramic fixed partial prostheses for posterior tooth restoration / 实用口腔医学杂志

ABSTRACT

Objective:To evaluate the outcome of implant-supported all-ceramic fixed partial prostheses (FPPs)in posterior area. Methods:The clinical data of 1 20 implants-supported 53 fixed dentures in 47 patients were collected from July 201 1 to June 201 2 and prospectively studied.Complication and failure of implants and /or prosthesis,biological and technical complications were evaluated. Results:43 restorations with 1 00 implants in 37 cases were followed up for 1 2 -24 months.Veneering ceramic chipping was observed in 9(20.9%)prostheses.Inflamed marginal gingivitis was found around 3(7.0%)prostheses.No implant was involved in technical complication.Cumulative survival rate was 1 00% for implant-based analysis and 1 00% for prostheses-based analysis.Conclusion:Implant-supported all-ceramic fixed partial dentures may be a feasible treatment modality for posterior dental restoration.
