Abstract
One hundred infrabony pockets with one- and two-wall bony defects were treated for reattachment. Mucoperiosteal flaps were raised, the tooth surfaces were scaled and planed, and the defects curetted. Flaps were sutured tightly and the sites protected with a surgical dressing. Antibiotic coverage was used in each case. Pre- and postoperative measurements were taken by the same clinician from the cemento-enamel junction to the base of the pocket. In 56 defects cancellous bone from the same patient was placed in the defect, and in 44 defects the treatment consisted only of open curettage without bone grafts. The results showed a trend towards more favourable clinical results using bone grafts; especially in the two-wall bony defects.
