An 11-year reevaluation of resin-bonded fixed partial dentures.
Clinical success of resin-bonded fixed partial dentures is primarily dependent on their long-term retention. Retention rates of resin-bonded prostheses placed in 66 patients treated by three dentists in private practice were evaluated in the present study. Seventy-seven resin-bonded fixed partial dentures were followed over a period of 1 year to 11 years. Thirty (39%) became dislodged, but nine were successfully rebonded; thus there were 21 failures (27%). Prosthesis location and operator expertise minimally influenced the longevity of these restorations, but the luting agents tested in this sample had a profound impact on retention. Debonding rates were excessive for some materials tested, whereas other agents proved to be predictable. Modifications in preparation design that enhanced resistance form were also likely contributors to improved retention rates.
