日本东京医科齿科大学的加藤一男和田端恒雄与旭光学工业公司共同研制成功了合成磷灰石陶瓷材料。其方法是:将碳酸钙粉末加热,再加入磷酸水溶液,升温到700℃,这时所得的晶体即为磷灰石粉末。然后再将粉末按需要加工成一定的形状,经1000℃～1100℃高温烧灼后,坚固成型,是最理想的人工牙种植材料。此材料无毒性,机械强度 Japan Tokyo Medical Dental University Kato Kazuo and Tian Hengda male and Asahi Optical Industries co-developed the successful synthesis of apatite ceramic materials. The method is: heating calcium carbonate powder, adding phosphoric acid water solution and raising the temperature to 700 DEG C, and the crystal obtained at this moment is apatite powder. And then the powder processed into a certain shape as needed, after 1000 ℃ ~ 1100 ℃ high temperature cauterization, solid molding, is the best artificial dental implant material. This material is non-toxic, mechanical strength
