Clinical case description:

This lower right first molar was deemed unrestorable following endodontic treatment. The tooth was extracted and a ridge preservation technique was used. Geistlich Bio-Oss® and Geistlich Bio-Gide® were applied. Following healing tooth 46 was replaced with an implant. At the time of implant placement an infrabony defect was detected on tooth 47 which was treated by GTR using Geistlich Bio-Oss® and Geistlich Bio-Gide®.
