Beskrivelse
Inclusion Criteria:
- Patients are systemically medically free according to the American Society of Anesthesiologists (ASA) considered as ASA I.
- Ability to maintain good oral hygiene as evidenced in recall visits.
- patients who had a partial or completely edentulous alveolar ridge with apparent 3D defect following teeth loss.
- All patients were free from any local or general disease that may interfere with bone healing and had no history of previous grafting procedure at the designated edentulous ridge.
- The ridge had to exhibit severe vertical and horizontal (3D) alveolar ridge deficiency with alveolar ridge height less than 7 mm from the alveolar crest to the inferior alveolar canal and width less than 5 mm which was firstly measured by CBCT, or a clinically apparent increase in inter-arch space relative to the adjacent natural teeth.
- Pre-operative clinical assessment of soft tissue coverage was done to cover the graft and its membrane, in addition to assessment of occlusion and inter-arch distance should allow for the graft, membrane, implan and the future prosthesis.
Exclusion Criteria:
- Smoker (> 25 cigarettes/ day).
- Patients undergoing radiotherapy or chemotherapy
- Patients having infection or local lesions in the area of surgery.
- Patients with diabetes mellitus or bone diseases which may compromise the results.
- Patient with poor oral hygiene or active periodontal disease.
- Patient with limited mouth opening.
- Participation in other clinical trials

Foranstaltningsbeskrivelse |
Tidsramme |
|---|---|---|
|
change in vertical height of ridge
Tidsramme: up to 6 months
|
Cone Beam Computed Tomography (CBCT) was done immediately (1 week) and after six months to evaluate the changes in vertical, horizontal and volumetric measurements of the ridge.
OnDemand3D™ software was used to evaluate vertical and horizontal height.
Measurements were taken as follows: From the toolbar, the ruler was selected from the measurement section.
