Abstract

Purpose: The purpose of this study was to evaluate the clinical, histological and radiographic outcomes of the calcium phosphate double-coated anorganic bovine bone (InduCera; Oscotec Inc., Seongnam, Gyeonggi, Republic of Korea) compared with that of anorganic bovine bone (Bio-Oss; Geistlich Biomaterials, Wolhusen, Switzerland) in maxillary sinus augmentation, prospectively.

Patients and methods: Twenty-eight sinuses in 25 patients (3 bilateral) with vertical alveolar bone height from 2 to 5 mm were included in this study. The maxillary sinus was augmented with InduCera or Bio-Oss, followed by a healing period of 6 months. Trephine cores were obtained for histomorphometric evaluation with the implant placement. Cone-beam computed tomography (CBCT) scans were taken at 1 week and 6 months after sinus augmentation.

Results: The graft sites were healed without any notable complications in both groups. In histomorphometric analysis, the area of the newly formed bone was measured as 21.37 ± 8.87% for InduCera and 23.02 ± 5.88% for Bio-Oss, with no significant differences. Radiographically, no statistically significant differences were calculated between the groups in bone height at baseline, the height of bone augmentation, the final alveolar bone height (alveolar bone height + augmented height) after 6 months in panoramic radiograph. There were also no significant differences in the shrinkage rate of the grafted area volume in CBCT.

Conclusion: Although calcium phosphate double-coated anorganic bovine bone showed no additional effect compared with anorganic bovine bone from a histological and radiographical point of view, it could be used as the bone graft material in maxillary sinus augmentation.

磷酸钙双包覆牛骨增强上颌窦:多中心随机对照临床试验及组织学和影像学评价。
目的:本研究的目的是评价磷酸钙双包覆牛骨(InduCera;Oscotec Inc.,城南,京畿,大韩民国)与无机牛骨(Bio-Oss;Geistlich Biomaterials, Wolhusen, Switzerland)在上颌窦隆胸术中的应用。患者和方法:本研究纳入25例(3例双侧)28个鼻窦,牙槽骨垂直高度为2 ~ 5mm。上颌窦用InduCera或Bio-Oss增强,随后愈合6个月。植入后,获得环钻核进行组织形态学评估。锥形束计算机断层扫描(CBCT)于窦增强后1周和6个月进行扫描。结果:两组患者移植部位均愈合,无明显并发症。在组织形态学分析中,InduCera组新生骨面积为21.37±8.87%,Bio-Oss组为23.02±5.88%,差异无统计学意义。影像学方面,两组患者基线骨高度、增强骨高度、6个月后全景x线片最终牙槽骨高度(牙槽骨高度+增强骨高度)差异无统计学意义。在CBCT上,移植面积体积的收缩率也无显著差异。结论:磷酸钙双包覆牛无机骨与牛无机骨相比,在组织学和影像学上均无明显差异,但可作为上颌窦增强的植骨材料。
