围绕种植体形成的口腔粘膜封闭,是含菌的口腔环境与无菌的粘膜下结缔组织间的界线。因此,良好的封闭不但能防止龈周组织感染,同时也是决定种植成败的关键因素之一。到目前为止,种植体的上皮附着是否存在,尚未同时得到光镜、电镜及组化方法的证实。从一系列的研究资料表明:种植体桩周区是非常薄弱的。细菌对种植体桩周的感染,和天然牙一样,是极为重要韵。因为龈下细菌是通过产生毒素、溶组织酶来破坏龈周组织,使种植体桩周感染,粘膜封闭被破坏,进而形成牙周袋,最终导致种植体与粘膜分离或脱落。在 Oral mucosa closed around the implants is the boundary between the buccal cavity containing bacteria and the sterile submucosal connective tissue. Therefore, a good seal will not only prevent peri peri-infection, but also determine the success or failure of planting one of the key factors. So far, the existence of epithelial attachment of implants has not yet been confirmed by light microscopy, electron microscopy and histochemistry. From a series of research data show that: implant pile perimeter area is very weak. Bacterial infection of the piles around the implant, like the natural teeth, is extremely important. Because subgingival bacteria through the production of toxins, tissue enzymes to damage the peri-peri-peri-implant tissue, so that the implant peritoneal infection, mucosal closure is destroyed, and then the formation of periodontal pocket, eventually leading to the separation and separation of the implant and mucosa. in
