I have treatment planned this patient for extraction of UR 1 [#8] and replacement with an implant. The tooth has had conventional endodontic therapy and then an apicoectomy. It has significant hard and soft tissue loss, advanced mobility and a periapical radiolucent lesion. It has a terminal prognosis. What is best to do here? Would it be better to extract the tooth, debride the socket and do socket preservation and allow the socket to heal and later install the implant? Would it be better to go back in a second time to do ridge augmentation and later install the implant? Or would it be better to extract the tooth, immediately install the implant at that time and do bone graft?
