Fixed bonded prosthodontics: a 10-year follow-up report. Part II. Clinical assessment

The survival rates of resin-bonded fixed partial dentures, bonded splints, and bonded combination splints and fixed partial dentures (splints with pontics replacing one or two missing teeth) were determined. For statistical analysis, the splints and splint-prostheses were combined into one group. The average age of all devices combined was 5.7 years. Eleven of 145 resin-bonded fixed partial dentures failed; the survival rate was 83.0%. There was no statistically significant difference between the survival rates of prostheses, whether bonded to prepared teeth or unprepared teeth. Fifteen of 98 splints and splint-prostheses failed. The survival rate of splints and splint-prostheses bonded to prepared teeth (71.6%) was higher than that of splints and splint-prostheses bonded to unprepared teeth (53.6%). To determine the continuing relevance of resin-bonded prostheses, the number of instances in which implant dentures could have been used was calculated. Implant treatment would have been possible in only 14 or 98 cases.
