摘要:

目的对比研究采用不同涂层的纯钛种植体表面骨结合力及耐腐蚀性。方法采用等离子喷涂技术在纯钛表面制备氮硅锆-羟磷灰石(ZrSiN-HA)复合涂层并植入实验动物下颌骨。利用扫描电镜(SEM)观察分析复合涂层的表面形貌,电子万能材料实验机对比检测ZrSiN-HA组、氮硅锆(ZrSiN)组、羟磷灰石(HA)组与纯钛种植体组涂层的骨结合力并观测各组断裂区域的形貌,电化学腐蚀测试系统对比检测4组涂层的耐腐蚀性。结果种植体表面喷涂ZrSiN-HA后较单纯喷涂HA的表面更加致密,结晶化明显;ZrSiN-HA涂层与其他涂层比较骨结合力最高,耐腐蚀性能最强。结论ZrSiN-HA涂层的应用有利于种植体的长期固位,对齿科修复体具有一定的应用价值。

Abstract:

Objective To compare the osseointegration and corrosion of different kind of coatings on pure titanium. ethods By plasma spraying technology, nitrogen silicon zirconium-hydroxylapatite(ZrSiN-HA) compound coating as prepared on the surface of pure titanium and the pure titanium was implanted with the mandible of the experimental nimal. The superficial appearance of the compound coating was observed and analyzed by scanning electron icroscope(SEM). The ZrSiN-HA, nitrogen silicon zirconium(ZrSiN), hydroxylapatite(HA) and pure titanium were ompared and examined. In the four groups, the bone binding force of coatings were detected, and the superficial ppearance of the break regions were observed by the electronic multipurpose material testing aircraft. In the four roups, the anticorrosive of coatings were compared and examined on the electrochemistry corrosion testing system. esults Experimental results indicated that the implant surface sprayed with the ZrSiN-HA was more compact than hat sprayed with HA. The crystallization was obvious. Compared with the other coatings, the bone binding force of he ZrSiN-HA coating was the highest, and its anticorrosive performance was the strongest. Conclusion The application f ZrSiN-HA coating is advantageous to the long-term retention of implant, and it has huge latent application alue to dental dummy.
