Histologic and histomorphometric assessment of implants and periapical tissues when placed in the sockets of extracted teeth, teeth with periapical lesions, and healed lesions: A canine study

Abstract

Eighteen canine mandibular premolars were divided into 3 groups. In group 1, implants were inserted in periapical lesions. In group 2, implants were inserted when lesions were radiographically healed. In group 3 (control), implants were inserted immediately after extraction. There was no significant difference in average bone implant contact between the 3 groups. Considering the limitations of this study, immediate placement of dental implants in tooth sockets with periapical lesions should be proposed only under special circumstances.
