A technique is presented for treating periodontal osseous defects. Medical grade calcium sulfate hemihydrate is used as both a component of a composite graft with demineralized freeze-dried bone allograft (DFDBA) and a barrier over the graft to contain it and to exclude unwanted soft tissue. A case report is presented demonstrating clinical and radiographic success using the technique in the resolution of a severe osseous defect on a maxillary lateral incisor.
本文介绍了一种治疗牙周骨缺损的技术。医用级半水硫酸钙既用作与脱矿冻干同种异体骨（DFDBA）复合移植的成分，又用作移植体上的屏障，以容纳移植体并排除不需要的软组织。本文还给出了一个病例报告，展示了使用该技术成功解决上颌侧切牙严重骨缺损的临床和影像学效果。
