악골 결손부에 이식된 Biphasic Calcium Phosphate (OssPol®)의 단기간 체적 안정성: Simplant Program을 이용한 3차원 부피 계측 연구

Abstract

bone. Materials and Methods: The subjects included in this study were 20 patients, matching the inclusion criteria of the current study, who received bone grafting treatment at Yonsei University Dental Hospital department of oral and maxillofacial surgery between march 2010 till September 2010. Postoperative cone beam CTs (Ray Co., Ltd./ Rayscan symphony, Seoul, South Korea) were taken for each patient at 1 and 6 months. All CBCT slices were fixed at 1.0mm intervals. The thickness of the grafted bone was measured at 1 and 6 months, by converting these images into Dicom files and using the Simplant® software program (Materalise, Leuven, Belgium). Results: As the result, 85.45% of transplatanted biphasic calcium phosphatemass is maintained until six months and the average volume loss from 1-month to 6-month is 0.24 cc. Conclusion: We conclude that, the biphasic calcium phosphate has enough short-term stability as a scaffold until the ingrowth of new bone apposition.
