The effects of groove depth of cylinder implant on bone anchorage

槽道设计是圆柱形种植体获得坚固骨支抗的重要因素。本研究旨在探讨圆柱形种植体槽深对骨支抗的影响。在4只猕猴的下颌骨中植入4种不同深度的种植体（0.15、0.25、0.35、0.45mm）。3个月后，对种植体-骨界面进行临床和组织学比较。0.15mm槽和0.25mm槽在皮质骨区或编织骨区显示高的骨接触率。但0.35mm和0.45 mm槽深组编织骨区的骨接触率较其他槽深组低。这些结果表明，圆柱形种植体设计中的槽深对骨支抗有影响。

The groove design is important factor for solid bone anchorage on cylinder implant. In this study we evaluated the effect of groove depth of cylinder implant on bone anchorage. Implants with 4 different depth grooves (0.15, 0.25, 0.35, 0.45mm) were inserted in mandible of 4 monkeys. Implant-bone interfaces were compared clinically and histologically after 3 months. 0.15mm groove and 0.25mm groove were showed high bone contact ratio in cortical bone area or woven bone area. But 0.35mm groove and 0.45 groove were showed lower bone contact ratio in woven bone area compared from other groove depths. These results suggested that bone anchorage had been effected by groove depth on cylinder implant design.
