【摘要】：目的:比較不同的純鈦種植體表面形貌對牙齦軟組織界面的影響,尋找一種有利于牙齦軟組織附著的種植體頸部表面形貌。方法:采用電化學方法使純鈦金屬種植體形成4種表面,即酸蝕組(AE組)納米表面、電化學腐蝕1和2組(ECE1和ECE2組)的微米表面、電化學腐蝕加酸蝕組(ECA組)的微米-納米表面,并以光滑組(S組)光滑表面作為對照,將5種試件即刻植于犬下頜骨中,術后20d及3個月分別處死各組犬,制作標本后采用掃描電鏡觀察牙齦軟組織與種植體表面結合界面的情況。結果:各組犬牙齦上皮與種植體表面連接緊密,組間比較未見明顯差異;去除軟組織后種植體表面未見上皮組織殘留。S組膠原纖維平行黏附于種植體表面,與種植體表面大部分開裂分離,去除軟組織后種植體表面殘留膠原纖維較少;其他各組膠原纖維均垂直扎向種植體表面,牙齦組織面與種植體表面形成復雜的微米-納米鑲嵌結構,與種植體表面開裂較少;ECE2組和ECA組去除軟組織后種植體表面殘留的膠原纖維多于AE組和ECE1組。結論:通過電化學方法處理得到的微米和微米-納米表面的種植體可明顯改善牙齦軟組織與種植體表面的黏附。
[Abstract]:Objective: to compare the effects of different pure titanium implants on the interface of gingival soft tissue, and to find a kind of cervical surface morphology which is favorable to the adhesion of soft tissue to the gingival tissue. Methods: the pure titanium implants were made into four kinds of surfaces by electrochemical method, that is, the nano-surface of acid etching group (AE group), the micron surface of group 1 and 2 (ECE1 and ECE2 group), and the micrometer surface of group 1 and 2 (ECE1 and ECE2 group). The micron-nanometer surface of the ECA group was added by electrochemical etching, and the smooth surface of the smooth group (S group) was used as the control. The five specimens were immediately implanted in the mandible of the dog. The dogs were killed 20 days and 3 months after operation. The interface between gingival soft tissue and implant surface was observed by scanning electron microscope. Results: the gingival epithelium and implant surface in each group were closely connected, but there was no significant difference between the two groups, and there was no residual epithelium on the implant surface after soft tissue removal, while collagen fibers in group S were attached to the implant surface in parallel. After removing soft tissue, there were fewer collagen fibers remaining on the implant surface, and the other groups of collagen fibers were perpendicular to the implant surface. The gingival tissue surface and implant surface formed complex micron-nano mosaic structure, and less cracking with implant surface, ECE2 group and ECA group after removing soft tissue implant surface residual collagen fiber more than AE group and ECE1 group. Conclusion: the adhesion of gingival soft tissue to implant surface can be significantly improved by electrochemical treatment of micrometer and micron-nano surface implants.
