Bone atrophy after tooth loss may leave insufficient bone for implant placement. Several reconstructive procedures for the maxilla have been proposed to increase alveolar bone dimensions in both the vertical and horizontal directions. Alveolar bone grafting from an intraoral donor site offers a successful treatment option to regain the original bone volume.

The present article describes the case of a 30-year-old male who reported to the Department of Oral Medicine and Oral Surgery at the University Dental Clinic of Monastir- Tunisia, for replacement of maxillary incisors 21 and 22, lost due to a traffic accident complicated by significant bone loss.

The patient underwent autogenous bone grafting using a modified Shell Technique, and autogenous bone was harvested from the mandibular ramus. The shells were trimmed to a thickness of 1 mm and placed to recontour the ideal shape of the alveolar ridge. The shells were then fixed with micro titanium screws, and the gap between the shells and the alveolar ridge was filled with a mixed xenograft and autogenous bone chips.

Postoperative follow-up was favorable, with considerable vertical and horizontal bone gain. This article aims to shed light on the importance of the Modified Shell Technique for vertical and horizontal bone provision and how it remains the "gold standard" for reconstructing bone loss, especially in the maxillary anterior region
