PURPOSE
Current literature has revealed that surface etching of endosseous implants can improve bone-implant contact. The aim of this study was to evaluate the differences in bone-implant contact (BIC) between sandblasted/acid-etched and machined-surface implants.
MATERIALS AND METHODS
Thirty-two Sprague-Dawley rats were used in this study. Two implant surfaces, Ecotek (sandblasted/ acid-etched) and machined, were used with 1 implant placed in each tibia of the animals. A total of 64 implants were placed. BIC was evaluated at 5, 15, 30, and 60 days. Histomorphometry of the BIC was evaluated statistically.
RESULTS
The sandblasted/acid-etched surface demonstrated a greater BIC percentage than the machined surface. This difference was statistically significant only at 30 and 60 days after healing.
DISCUSSION AND CONCLUSION
The sandblasted/acid-etched surface demonstrated a stronger bone response than the machined one at a later period of healing.
目的
当前文献表明，骨内种植体的表面蚀刻可改善骨与种植体的接触。本研究的目的是评估喷砂/酸蚀表面种植体与机械加工表面种植体在骨与种植体接触（BIC）方面的差异。
材料与方法
本研究使用了32只Sprague-Dawley大鼠。使用两种种植体表面，即Ecotek（喷砂/酸蚀）和机械加工表面，在每只动物的胫骨中植入1枚种植体。共植入64枚种植体。在第5、15、30和60天评估BIC。对BIC的组织形态计量学进行统计学评估。
结果
喷砂/酸蚀表面的BIC百分比高于机械加工表面。仅在愈合后30天和60天，这种差异具有统计学意义。
讨论与结论
在愈合后期，喷砂/酸蚀表面比机械加工表面表现出更强的骨反应。
