近年来,各类陶瓷作为新的口腔科种植材料受到各方面注意。理由是陶瓷的生物适应性比金属高分子材料等优越。现已开发出的有氧化铝系统、碳系统等。在日本独自开发的氧化铝单晶种植体,近年来颇为普及。作者进行了磷酸钙陶瓷人工牙根的实验室观察和临床研究。发现第一,这种陶瓷是生物硬组织中无机质的主要成份,存在于生物体内,是生物体的重要组成成份,且和骨组织极易结合。第二,不含有机成份的磷酸钙陶瓷不存在生物拒绝反应,无被排斥之危险。在生物体内,生物学稳定性高。众所周知,
In recent years, various types of ceramics as a new stomatal planting material have been all aspects of attention. The reason is that ceramic biocompatibility superior to metal polymer materials. Already developed alumina system, carbon system and so on. Alumina single crystal implants developed in Japan alone are quite common in recent years. The authors conducted a laboratory observation and clinical study of calcium phosphate ceramic artificial tooth root. Found first, this ceramic is a bio-hard tissue bio-main components exist in the body, is an important component of the organism, and bone tissue easily combined. Second, calcium phosphate ceramic without organic components does not exist biological rejection reaction, there is no danger of rejection. In biology, biological stability is high. As we all know,
