人工合成是趋势,是未来。
但目前在口腔领域,理论上同种异体骨理论上比异种骨更理想。
bio-oss最早出现是因为有些国家不许用同种异体骨。 他制作的最早目的就是把牛骨处理后像人骨结构。
Bone allografts are an excellent replacement option with good osteoconductive properties and certain types are known to be osteoinductive due to their release of bone morphogenetic proteins (BMPs) in demineralized freeze-dried bone allografts (DFDBAs).8 Xenografts on the other hand are also a highly utilized bone grafting material, especially in countries where the use of allografts is not permitted. Xenografts were first developed to act as a standard replacement material similar to allografts, it has since been revealed that unlike allografts, xenografts typically do not resorb over time, and in particular, the intensively studied deproteinized bovine bone mineral (DBBM, Bio-Oss?, Geistlich, Switzerland) has been characterized as a nonresorbable material in many studies due to its histological stability over time.
