Background: After tooth extraction changes of the shape of the alveolar bone follows a predictable pattern, which proves to be challenging in restoring its form and function, especially in the esthetic zone. Autogenous grafts remain the gold standard because of their predictability. The island osteoperiosteal flap (I-flap) is introduced as a modified alveolar split bone grafting technique used to gain width, height and modify the facial or buccal bone plate position. Aim of the study: This study aims to evaluate in anterior atrophic maxillary ridge augmentation using guided unreflected island osteoperiosteal flap (I-Flap) approach with simultaneous implant placement and interpostional bone grafting in comparison to computer guided ridge splitting method.

Crestal incision using no. 15 blade on a bard parker no. 3. Two blind lateral vertical ostotomies at about 1.5 to 2 mm from the adjacent tooth roots to preserve subpapillary and root bone coverage. These cuts are to ensure the complete fracture of buccal plate while being attached to the overlying periosteum.
Crestal incision and 2 vertical releasing incisions will be made using a no.15 blade mounted on a Bard Parker no.3. Then, a full mucoperiosteal flap reflection to expose bone.

Change in pain scores
Pain (by Visual Analogous Scale): Score 0 - No pain. Scores 1 to 3 - Mild pain. Scores 3 to 7 - Moderate pain. scores 7 to 10 - severe pain.
Time frame: 1 day, 3rd day and 1 week
Secondary implant stability
implant stability was measured using ostell device
Time frame: 4 months
Change in bone level (bone gain)
Immediate post-operative CBCT (T1) will be done to measure the alveolar bone gain, to assess the proper implant positioning, and finally to measure the width of the out-fractured buccal plate and the amount of interpositional bone graft. Four months postoperatively CBCT (T2) will be done to measure amount of bone gain
Time frame: Baseline and 4 months
Change in bone density
Bone density at implant body is measured by using computerized tomography values
Time frame: baseline and 4 months
