The study aims toward using autogenous bone grafts to solve decreased bone quantity in anterior maxilla while allowing the patient to recieve implants simultaneously (same time of grafting).

• Chin bone ring will be harvested from patient's(10 in number) chin to augment the recent extraction socket with buccal bone defect, followed by implant placement.
• The process of harvesting and placement of ring will be computer guided which adds lots of accuracy to the bone ring required size from the donor site and the proper placement of both the ring and the implant at the recipient site

Inclusion Criteria:

• Patients with non-restorable teeth in the maxillary anterior region with insufficient buccal bone height or buccal bone defect.
• Patients who have given their consent for this trial.
• Both genders males and females will be included.

Exclusion Criteria:
