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.
