Brief Summary

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.

Conditions

Maxillary Alveolar Reconstruction; Virtual Surgical Planning

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: TREATMENT
• Blinding Strategy: NONE

Study Groups

Computer guided island flap

Group Type: EXPERIMENTAL

Island osteoperiosteal flap

Intervention Type: PROCEDURE

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.

Computer guided conventional ridge splitting

Group Type: ACTIVE_COMPARATOR

Conventional ridge splitting

Intervention Type: PROCEDURE

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.
