Study Overview
Brief Summary
the aim of this study was to assess both horizontal and vertical alveolar bone augmentation for sever atrophied anterior maxilla and mandible, using L- shape autogenous bone block harvested from the symphysis. eleven partially edentulous patients seeking horizontal and vertical alveolar bone augmentation in the anterior maxilla or mandible were included in this study. For each patient, autogenous bone block was harvested from the symphysis, trimmed to L-shape and used to augment the anterior maxilla or mandible horizontally and vertically. Horizontal and vertical bone gain was measured by CBCT immediate postoperative and at 6months after grafting.
Detailed Description
A total of 11 partially edentulous patients needing extensive horizontal and vertical bone augmentation in the anterior maxilla or mandible were included in this study. The patients were recruited from the Outpatient Clinic of Oral and Maxillofacial Department, Faculty of Dentistry, Mansoura University.
Before the surgical operation, all patients were informed about the treatment options, the nature of the operation, and the probable postoperative sequelae. An informed consent was signed from each patient.
Preoperative assessment
- Patients' medical status were carefully evaluated.
- A thorough intraoral examination was done to evaluate oral hygiene, occlusion, and mucosa that covers the recipient and donor sites.
- Preoperative CBCT was done for each patient to evaluate bone width and height in both the recipient and donor sites.
Surgical procedures Prophylactic antibiotic 600 mg Clindamycin (Clindam, Sigma, Egypt) was administered 1 hour before surgery. A thorough mouth rinsing using Chlorhexidine mouth wash (Hexitol, Adco, Egypt) for about 1 min was done immediately before surgery.

Outcomes
Primary Outcomes
numerical rating scale for pain measurement
Time Frame: 3 days post-surgery
Pain intensity was measured at three days after surgery on a 0 to 10 numerical rating scale in which 0 = no pain, 1-3 = mild pain, 4-6 = moderate pain, 7-9 = severe pain, and 10 = the worst pain imaginable.
questionnaire for sensory disturbance
Time Frame: with in 6 months
This was assessed by patients' complaint (patient questionnaire) to determine any change in subjective sensation in the lower lip, chin and mental area. if there is pain or not. if there is numbness or not.
infection and dehiscence of soft tissue
Time Frame: with in 6 months
This was determined clinically by presence=1 or absence=0, of pus formation or graftb exposure.
width of the alveolar ridge
Time Frame: immediate post-operative and after 6 months
CBCT cross section view was used for evaluation of alveolar ridge width and preoperatively, immediate postoperative (within one week after grafting), and at 6 months after grafting.
height of the alveolar ridge
Time Frame: immediate post-operative and after 6 months
CBCT cross section view was used for evaluation of alveolar height preoperatively, immediate postoperative (within one week after grafting), and at 6 months after grafting.
