目的探讨直线和狭窄结构的光滑和粗糙种植体表面与种植体骨表面微损伤的关系。材料和方法将直线和锥形、粗糙和光滑表面的诺贝尔Biocare种植体植入绵羊下颌骨。结果与种植体类型无关，种植体近端的微损伤、微裂纹、交叉性损伤和弥漫性损伤明显高于远离种植体的骨微损伤。结论与粗锥形、光滑圆柱形和光滑圆锥形种植体相比，粗糙圆柱形种植体骨基质微损伤比例增加。本文引用：Barteed PM，Kuliwaba JS，Lee V，Shah S，Marino V，Fazzalari NL。表面粗糙度和形状对钛牙种植体周围骨表面微损伤的影响口头实施。Res.22,2011年；613-618doi：10.1111/j.1600-0501.2010.02024.x.
ObjectivesTo assess the relationship between smooth and roughened implant surfaces of straight and narrow configurations with respect to microdamage of the bone surface during placement of dental implantsMaterials and methodsStraight and tapered, rough and smooth surface Nobel Biocare implants were placed into sheep mandibles. Microdamage within the bone adjacent to the implant surface was quantitated using a semi-automated digitized histomorphometric method.ResultsIndependent of implant type, microdamage, microcracks, cross-hatch damage and diffuse damage were significantly higher close to the implants compared with far from the implants. Microcracks and cross-hatch damage were higher for the rough cylindrical implants than all the other implant types.ConclusionsInsertion of a rough cylindrical implant type results in an increased fraction of microdamaged bone matrix in comparison to rough tapered, smooth cylindrical and smooth tapered implants.To cite this article: Bartold PM, Kuliwaba JS, Lee V, Shah S, Marino V, Fazzalari NL.
