Rough implant surfaces have shown improved osseointegration rates. In a majority of dental implants, the microrough surfaces are obtained by grit blasting and/or acid-etching. The aim of this contribution was to evaluate the effects of acid-etching, after the grit-blasted treatment in titanium dental implants, on surface wettability, surface energy, osteoblast responses and its osseointegration behavior. Four surfaces were studied: as-machined, acid-etched, micro-rough by grit-blasting and the combination grit-blasted surface with acid-etched. The surfaces with increasing roughness show more osteoblastic adhered cells. This effect was most pronounced on samples blasted and blasted with acid-etching. The roughness obtained by grit-blasting is the main factor in comparison with the acid etching treatment in the biological response. These results were confirmed in vivo tests and histological analysis. The results demonstrated that the combination of the grit-blasted and acid-etched accelerated lightly bone regeneration at the different periods of implantation in comparison with the grit-blasted implants.
粗糙的种植体表面显示出更高的骨整合率。在大多数牙科种植体中，微粗糙表面是通过喷砂和/或酸蚀获得的。本研究的目的是评估喷砂处理后酸蚀对钛牙科种植体表面润湿性、表面能、成骨细胞反应及其骨整合行为的影响。研究了四种表面：机械加工表面、酸蚀表面、喷砂微粗糙表面和喷砂酸蚀组合表面。随着粗糙度的增加，黏附的成骨细胞增多。喷砂和喷砂酸蚀处理的样品效果最为明显。与酸蚀处理相比，喷砂处理获得的粗糙度是影响生物反应的主要因素。体内试验和组织学分析证实了这些结果。结果表明，与喷砂种植体相比，喷砂酸蚀处理组合加速了不同植入期的轻度骨再生。
