Anterior Maxilla Alveolar Bone Deficiency
Conditions
Keywords
bone deficiency, khoury bone augmentation, anterior maxilla, vestibular shifted flap
Brief summary
two groups of patients both have alveolar bone deficiency in anterior maxilla, one group will be subjected to khoury bone augmentation with conventional flap the other with vestibular shifted flap
Detailed description
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

Masking
SINGLE (Subject)
Masking description
This trial is considered a randomized single blind clinical trial due to: * The participants will be blinded to the technique that will be used during the surgical procedure. * The operator will not be blinded for both techniques during the surgical procedure as the two techniques are different. * The outcome assessor cannot be blinded.
Intervention model description
Parallel Assignment Randomized clinical trial A trial will be carried out in hospital of Oral and Maxilofacial surgery department- Faculty of Oral and Dental Medicine Cairo University. Equal randomization: participants with equal probabilities for intervention Positive controlled :Both groups receiving treatment Parallel group study: Each group of patients receives a single treatment simultaneously.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Horizontal Bone Gain Assessed in millimeters by Cone-Beam Computed Tomography (CBCT) | 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
| Measure | Time frame | Description |
|---|---|---|
| Width of Keratinized Tissue Assessed by Periodontal Probe | 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. |
