Comparative Study Between Porcine and Autologous Cortical Plates
17. december 2019 opdateret af: Jesús Torres García Denche, Universidad Complutense de Madrid
Split Bone Block Technique: Clinical and Radiographic Study Between Autologous and Porcine Xenogeneic Cortical Plates. Randomized Clinical Trial
The aim of this study is to evaluate the outcome of three-dimensional bone regeneration procedures using thin cortical porcine xenograft plates in combination with autogenous bone chips compared with thin autogenous cortical plates and autogenous bone chips.

Detaljeret beskrivelse
Materials and methods: 16 patients referred for implant placement and with insufficient bucco-lingual (BL) alveolar bone width (<4 mm) were included in the study.
Patients received autogenous cortical plates (ACP) of either porcine xenogeneic (XCP).
The aforementioned groups were compared in regards to bone augmentation using General Estimating Equations (GEE) and logistic regression.
Demographic data, trabecular bone density, graft site, postoperative pain, and time consuming were also analyzed

Beskrivelse
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.

Volume of bone augmentation
Tidsramme: 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
Tidsramme: 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
Tidsramme: 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.
