PURPOSE
To evaluate the regenerative potential of a fully synthesized homogenous hydroxyapatite:β-tricalcium phosphate 60:40 alloplast material in sinus lift procedures.
MATERIALS AND METHODS
Hydroxyapatite:β-tricalcium phosphate was used for sinus floor augmentation. After 9 months, 12 biopsies were taken from 12 patients. Routine histologic processing was performed and specimens were analyzed using a light microscope and a digital camera.
RESULTS
Histologic evaluation showed 26.4% newly formed bone, 27.3% residual graft material, and 46.3% bone marrow. The osteoconductive index was 33.5%.
CONCLUSIONS
Hydroxyapatite:β-tricalcium phosphate 60:40 alloplast material was found to be biocompatible and osteoconductive in maxillary sinus augmentation procedures.
目的
评估一种完全合成的均质羟基磷灰石：β-磷酸三钙60:40异体骨材料在鼻窦提升手术中的再生潜力。
材料与方法
使用羟基磷灰石：β-磷酸三钙进行鼻窦底增高术。9个月后，从12例患者身上获取12份活检组织。进行常规组织学处理，并使用光学显微镜和数码相机对标本进行分析。
结果
组织学评估显示，新形成的骨组织占26.4%，残留移植材料占27.3%，骨髓占46.3%。骨传导指数为33.5%。
结论
发现在上颌窦增高手术中，羟基磷灰石：β-磷酸三钙60:40异体骨材料具有生物相容性和骨传导性。
