Conventional Flap Versus Vestibular Flap in Bone Augmentation ((RCT))
Assessment of Vestibular Shifted Flap Versus Conventional Flap on Ridge Augmentation in Patients With Anterior Maxillary Bony Deficiency: a Randomized Control Trial
Studieoversikt
Status
Intervensjon / Behandling
Detaljert beskrivelse
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

Horizontal Bone Gain Assessed in millimeters by Cone-Beam Computed Tomography (CBCT)
Tidsramme: 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.
