种植牙是70年代后期逐渐兴起的一门崭新的牙科技术,它是将生物材料制成的种植体植入人体颌骨中,在其桩部塑造牙冠外形,获得与天然牙一样的形态及功能。种植牙的主体是埋入骨内的种植体,它可由多种材料制成,但目前所用的主要是两种材料:一种是钛合金种植体,另一种是内层为钛合金,外层喷涂有羟基磷灰石的种植体。两种材料制成的种植体均有良好的强度及生物相容性。根据植入方式的不同,又可将种植牙分为一段式种植牙及二段式种植牙,所谓一段式种植体就是种植体的根部与桩部是联为一体的,植入种植体后,其桩部暴露在口腔内;二段式则是种植牙根部与桩部是分开的,先将根部植入
Implantation is a brand new dental technique that is gradually emerging in the late 1970s. It implants implants made of biological materials into the human jaw, shapes the crown in the stump, and obtains the same morphology as the natural teeth. Features. The main implant is embedded in the bone implants, which can be made of a variety of materials, but currently used mainly two kinds of materials: one is a titanium alloy implant, the other is the inner layer of titanium alloy, the outer layer Hydroxyapatite-coated implants. Implants made of both materials have good strength and biocompatibility. According to the different implantation methods, but also can be divided into one-stage dental implant and two-stage dental implant, the so-called one-stage implant is the root of the implant and the stump is a joint, after the implant, The stump is exposed in the oral cavity; the two-stage type is that the root of the implant is separated from the stump, the root is implanted first
