※ 引述《decay2 (decay)》之铭言： : ※ 引述《rabbi (阿德)》之铭言： : : 请问一下 : : dental implant 所谓 one piece design 和 two piece design : : 是什麽意思 有什麽作用 (我不太清楚这词 可能提问的不好) : : 另外google出一堆英文又发现submerged 和 non-submerged 等词 : : 又是代表什麽意思呢 : : 麻烦各位解说 谢谢!! : one piece design是指手术完後直接露出在牙龈外(non-submerged), : 而two piece design是指手术完後龈把整个植体包覆(也就是submerged), : non-submerged的好处是在接abument时不用再切开牙龈, 减少病人再一次的疼痛, : 但因为植牙手术完後就外露出来, 也相对增加感染的风险, 两者各有利弊. 以我个人的认知 上面说的这些最正确的名称应该是one stage和two stage 所谓的dental implant其实包含fixture和abutment one piece应该是fixture和abutment一体成形 我的根据是 http://medical-dictionary.thefreedictionary.com/two-piece+implant two piece implant的定义是either end-osteal or subperiosteal, having its infrastructure and abutment in separate parts. Generally, the abutment, which is threaded, is screwed to the infrastructure some weeks after its incision, so that healing has taken place. two stage implant的定义是an endosseous implant placed in the bone, with the soft tissue over the implant being sutured closed in a stage-one surgery to allow osseointegration of the implant. A second surgery is performed later in which the soft tissue over the submerged implant is removed in order to thread an abutment into the implant so that a prosthesis can be attached; also known as a submergible implant. 至於non-submerged应该就是所谓的one stage 传统的ITI算是一个很好的例子 他有一段1.8mm或2.8mm的smooth surface是在bone level之上 让fixture和abutment交接的microgap远离bone 有些人的论点是这可以减少bone的吸收 这是我比较能认同的观点 one stage implant的话ITI是我的首选 一般传统two stage implant由於microgap在bone level 所以有发展出platform switch 不过细菌会不会因为你把microgap往内缩就跑不过去 我个人是不相信啦 当然这个见仁见智 --
