The in vivo interface attachment strength and histology of CSTi (cancellous-structured titanium)-coated cylindrical dental implants were compared with those of solid HA-coated dental implants of the same dimensions and geometry. The implants were placed in healed extraction sites in the mandibles and prepared unicortical sites in the femurs of canines. The mandibular implants were evaluated at two, four, eight, and 12 weeks post-implantation, and the femoral implants were evaluated at two, four, eight, 12, 16, 24, and 34 weeks post-implantation. The interface attachment strength of the CSTi implants placed in the mandible at two, four, eight, and 12 weeks was not significantly different from that of the control HA-coated implants. In the femurs, the CSTi implants were significantly stronger than the HA-coated implants at all time periods except 12 weeks (two, four, eight, 16, 24, and 34 weeks). The CSTi implants were able to achieve high percentages of bone ingrowth in the mandible and femur of up to 92% at the later time periods, thus providing a sound interface bond.
将具有松质结构的钛（CSTi）涂层圆柱形牙种植体的体内界面附着强度和组织学与相同尺寸和几何形状的固体羟基磷灰石（HA）涂层牙种植体进行比较。将种植体植入犬下颌骨的愈合拔牙部位以及犬股骨的单皮质部位。对下颌骨种植体在植入后2周、4周、8周和12周进行评估，对股骨种植体在植入后2周、4周、8周、12周、16周、24周和34周进行评估。在2周、4周、8周和12周时植入下颌骨的CSTi种植体的界面附着强度与对照HA涂层种植体的界面附着强度无显著差异。在股骨中，除12周（2周、4周、8周、16周、24周和34周）外，CSTi种植体在所有时间段均显著强于HA涂层种植体。CSTi种植体能够在后期使下颌骨和股骨中的骨长入比例高达92%，从而提供良好的界面结合。
