Inclusion criteria
* Inclusion criteria: 1. Patients from both genders with the age range of 18-60 years with good systemic health, no contraindication for periodontal surgery and able to maintain good oral hygiene. 2. Patient with anterior maxillary alveolar ridge deficiency (horizontal, vertical or combined defects) less than 2 mm in width or less than 6 mm in height - measured from the alveolar crest to the basal bone in order to be enrolled in this study. (56) 3. Adequate zone of keratinized gingiva at minimum 3mms. 4. Patient with sufficient inter-arch space for future dental rehabilitation. 5. Subjects who are not on any medication known to interfere with periodontal tissue health or healing within 6 months of the study.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| clinical evaluation | 6 months | The patients will be followed up clinically postoperatively every 48-72 hours for the first week then after 2weeks then one month and then after 3 months then after 6 months for preserving: Presence/absence of mesh instability, flap dehiscence, exposed mesh, bone graft loss outside the flap, hematoma or laceration. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| radiographic bone volume | 6,12 months | A CBCT will be done preoperatively (base line) and after 6 months and finally after 12 months postoperatively to assess dimensions of newly formed bone and its density. |
| histologically | 6 months | The bone cores, left inside the trephine burs will be carefully rinsed with a cold 5% glucose solution. The specimens will be fixed in 10% formalin solution at pH 7.2 for a week and dehydrated with a graded series of alcohols. After the pre-infiltration treatment the bone cores will then be completely embedded in 100% resin until the specimens became transparent. Finally, the bone cores will be oriented and polymerized. |
