Beskrivning
Inclusion Criteria:
- Patients were enrolled in the study on the basis of having insufficient bone height (<6mm), width (<3mm) or both, in either maxilla or mandible
Exclusion Criteria:
Patients with severe systemic disease (American Society of Anesthesiology III or IV) were excluded from the study.
In addition, patients who were pregnant, or patients with diseases affecting bone, such as:Paget's disease, osteomalacia, diabetes, vitamin D deficiency, alcoholism, hyperthyroidism cancer or osteoporosis as well as those on medications that might affect bone metabolism, such as bisphosphonates, corticosteroids or antiepileptic medicaments were also excluded from the study.

A graft surgery using autogenous bone chips surrounded by a rigid framework made over the atrophic sites of the mandible and maxilla to obtain bone augmentation to support dental implants

Volume of bone augmentation
Tidsram: 4 months
|
Volume of bone augmentation of the surgical sites was measured in the postoperative parasagittal CT scans using a region of interest (ROI) containing the entire bone box regenerated area using the closed polygon tool of the OsiriX software.
This measurements have been done in mm3

Postoperative pain
Tidsram: 4 months
|
The amount of pain was classified into three categories: heavy pain, with the patient taking more than eight painkillers (ibuprofen 400); moderate pain, when the patient took four to eight painkillers; or little pain, when the patient needed fewer than four painkillers.

Bone box time consuming
Tidsram: Minutes
|
In the control group this was measured from the moment the osteotomy incision began with the MicroSaw until the bone block was completely removed, splitting cortical plates and fixation to the buccal and lingual/palatal side of the bone defect using osteosynthesis screws after it is filled with the bone chips harvested previously.
In experimental group the time was measured from the open of porcine cortical plate envelope until the bone box was completely filled and sealed.
