Clinicians have been using implants made by titanium or delrin with varying results. In this study dividable implants, bone growth chambers (BGC), of titanium and delrin were inserted into the rabbit tibia. The ingrowth of hard tissue into a canal in the implant was evaluated after 3 weeks by microradiography and numerically determined by computer analysis. Results showed that bone ingrowth into titanium implants was significantly larger than into delrin implants (P less than 0.005). The possible reasons for this are discussed.
临床医生一直在使用由钛或聚甲醛制造的植入物，效果各异。在本研究中，将可分割的钛和聚甲醛植入物——骨生长室（BGC）插入兔胫骨。3周后，通过显微放射照相术评估硬组织向植入物管道内的生长情况，并通过计算机分析进行数值测定。结果显示，钛植入物中的骨生长明显大于聚甲醛植入物（P小于0.005）。本文讨论了造成这种情况的可能原因。
