The development of bone augmentation procedures has allowed CASE REPORT

sufficient amount of bone for standard implant placement. Thus, upper front tooth region (Figure 1). A cone-beam computed tomography
the indications for implants have broadened to include jaw (CBCT) scan showed a severe periapical lesion with significant alveolar
regions with bone defects and those with a bone anatomy that is bone loss (Figures 2 to 5). Failing endodontic treatments were also
unfavorable for implant anchorage. observed in both the upper central incisor regions (Figures 4 and 5)
Among the different techniques, the best-documented and necessitating the need for extractions. Since patient was young and
most widely used method to augment bone in localized alveolar healthy, dental implants were discussed as an option post-extraction,
