Healing following GTR treatment of bone defects distal to mandibular 2nd molars after surgical removal of impacted 3rd molars

Abstract

Most bone defects showed healing up to 10%-20% of the tooth length at both test and control sites. 2 test and 2 control sites showed no improvement in the bone level. The mean values of bone healing registered in mm from the cemento-enamel junction (CEJ) were 2.6 +/- 2.19 SD and 3.0 +/- 2.20 SD for test and control sites, respectively. Different factors affecting the healing result are discussed.
