Resin-bonded fixed partial dentures and splints in periodontally compromised patients: a 10-year follow-up.

In the present study, 139 periodontally compromised patients received a complete periodontal treatment; in 104 cases this was followed by orthodontic treatment. At the end of the entire therapy, a total of 150 Maryland restorations (69 resin-bonded fixed partial dentures and 81 resin-bonded splints) was placed and then followed for a period of up to 10 years (mean 6.7 y). Thirteen fixed partial dentures and 16 splints failed during the observation period; the 10-year cumulative survival rate from lifetable analysis was 76.2% (70.6% for fixed partial dentures and 80.7% for splints).
