About this study
The procedure begins with preoperative preparation, including patient positioning in a semi supine position with appropriate head support, induction of local anesthesia, and meticulous surgical site sterilization.
- Full thickness Vestibular flap and 2 horizontal releasing incision are made (Key Concept: The vestibular shifted flap provides additional flap length by translating vestibular mucosa coronally while preserving keratinized tissue and blood supply) in a group and conventional flap in the other group
- Flap elevation: Full thickness flap in the Donor site
- Using piezoelectric device, thin cortical bone blocks (1-1.5 mm thick) are harvested.
- Blocks are carefully shaped into flat "plates."
- The shell Graft placed, adapted and fixed with microscrews to restore desired horizontal dimension
- The space between the host bone and the fixed cortical plates is filled with bone particles.
- Tension free bilayered suturing

Treatment and study plan
vestibular shifted flap for bone augmentation
ProcedureThe procedure begins with preoperative preparation, including patient positioning in a semi supine position with appropriate head support, induction of local anesthesia, and meticulous surgical site sterilization.
- Full thickness Vestibular flap and 2 horizontal releasing incision are made (Key Concept: The vestibular shifted flap provides additional flap length by translating vestibular mucosa coronally while preserving keratinized tissue and blood supply)
- Flap elevation: Full thickness flap in the Donor site
- Using piezoelectric device, thin cortical bone blocks (1-1.5 mm thick) are harvested.
- Blocks are carefully shaped into flat "plates."
- The shell Graft placed, adapted and fixed with microscrews to restore desired horizontal dimension
. • The space between the host bone and the fixed cortical plates is filled with bone particles.
- Tension free bilayered suturing.

Primary outcomes
-
Horizontal Bone Gain Assessed in millimeters by Cone-Beam Computed Tomography (CBCT)
Time frame: 6 months
Horizontal bone gain will be evaluated using cone-beam computed tomography (CBCT). Alveolar ridge width will be measured in millimeters (mm) at standardized reference points before the augmentation procedure and at 6 months postoperatively. The outcome will be calculated as the change in ridge width (mm) from baseline to follow-up.
Secondary outcomes
-
Width of Keratinized Tissue Assessed by Periodontal Probe
Time frame: 6 months
The width of keratinized tissue will be measured clinically using a calibrated periodontal probe and recorded in millimeters (mm) at baseline and 6 months postoperatively. The outcome will be calculated as the change in keratinized tissue width from baseline to follow-up.
