The current study demonstrates that implants placed with an initially thicker peri-implant soft tissue have less radiographic MBL in the short term.

Implant placement in patients with a history of GAgP might be considered a viable option to restore oral function with survival outcomes similar to those found in both patients with CP and HPs. However, the risk ratio for failure in patients with AgP is significantly higher when compared with HPs (4.0) and those with CP (3.97).

A number of diagnostic and management challenges exist for achieving complete regeneration of large through-and-through periapical lesions. An unfavorable endodontic outcome may occur as a result of uncontrolled infection or unpredictable bone healing. This article presents a case with a 15 × 15-mm through-and-through periapical lesion and persistent gingival swelling. Endodontic microsurgery and guided tissue regeneration were performed using a resorbable membrane and osseous substitute. A 2-year postoperative radiograph revealed complete resolution of the periapical radiolucency. Seven-year clinical and radiographic follow-up showed that the tooth was asymptomatic and a long-term successful outcome had been maintained.
