Fixed partial dentures in an up to 8-year follow-up

Information on the longevity of fiber-reinforced composite fixed partial dentures (inlay fpds) should be considered in the selection of materials,operative techniques and patient instructions related to prognosis and long-term cost-effectiveness. objective: this study evaluated the long-term survival of fiber-reinforced,adhesively-bonded composite prostheses placed in posterior teeth. materials and methods: twenty-one patients that received adhesively bonded polyethylene inlay fpds in posterior teeth were selected from a private practice dental office and invited to evaluation. of the eligible 21 patients,13 (mean age 50.3 ±11.5 years) agreed to be enrolled as participants,providing 22 restorations,as several subjects presented more than one inlay fpd. one dentist placed all inlay fpds using ribbond as reinforcement and tetric ceram/durafil or charisma/renamel composite combinations,according to manufacturer's instructions. two independent calibrated operators performed the evaluation,using modified usphs criteria. survival functions of restorations were analyzed with kaplan-meier and log rank test (α = 0.05). results: the majority of restorations received a or b scores. four (18.2%) inlay fpds fractured among the 22 evaluated. the mean estimate survival rate was 7 years (95% ci: 5.9 to 8.1),and the overall percentage of survival was 81.8%. there were no significant differences (p>0.05) between composite combinations or tooth location considering all clinical aspects evaluated and survival functions. conclusion: posterior fiber-reinforced fixed partial dentures exhibited acceptable clinical performance after a period up to 8 years.
