46例非连续患者接受正颌外科手术，其中珊瑚多孔羟基磷灰石（Interpore-200）块被用来代替间置骨移植是本报告的主题。手术包括上颌（7例）和下巴（12例）向下复位，唇腭裂患者（4例）和非唇腭裂患者（13例）的上颌前移，以及上颌横向扩张（12例）。本研究中纳入的患者仅为在无法获得羟基磷灰石的情况下采集骨移植物的患者。共植入93个解剖部位。使用植入物的并发症发生率为4.3%。随访6~20个月，平均9.3个月。此时，除了两名接受上颌骨扩张的患者外，所有患者的头影测量均证实了骨稳定性。讨论了珊瑚源多孔块状羟基磷灰石的生物学行为和力学性能。这些种植体特征使其成为正颌手术中插入使用的可行骨移植替代物。强调了其使用的适当适应症以及减少并发症的技术细节。
Forty-six nonconsecutive patients undergoing orthognathic surgery in whom blocks of coralline, porous hydroxyapatite (Interpore-200) were used in lieu of interpositional bone grafts are the subjects of this report. Surgical procedures included inferior repositioning of the maxilla (7) and chin (12), maxillary advancements in cleft (4) and noncleft individuals (13), and transverse maxillary expansions (12). Patients included in this study were only those in whom bone grafts would have been harvested had hydroxyapatite not been available. A total of 93 anatomic sites were implanted. The complication rate attributable to the use of the implant was 4.3 percent. Follow-up period ranged from 6 to 20 months, with a mean of 9.3 months. At this time, osseous stability was confirmed cephalometrically in all but two patients undergoing maxillary expansions. The biologic behavior and mechanical properties of coralline-derived, porous, block hydroxyapatite are discussed. These implant characteristics make it a feasible bone graft substitute for interpositional use in orthognathic surgery. Proper indications for its use as well as technical details to minimize complications are stressed.
