Although the patient was pleased with the treatment, the gingival infection and fistula did not improve. The tooth mobility increases over the years (Fig.3). He will return for evaluation next Monday. What should be done?
After tooth extraction (Fig.4), a medium-sized implant (4.5 mm, Fig.5 green) will be placed in the mesial socket, but the coronal end of the long axis of the implant (white line) will be in the middle of the socket for future restoration.
