摘要

目的:热的过量产生可导致临床骨结合失败。本研究比较了常规钻孔、环钻和牙槽扩张器在截骨过程中产生的热量。材料和方法:在10块牛股骨上进行了体外研究。在每根股骨上,使用常规钻孔、环钻和牙槽扩张器在1.5cm的距离上准备3个截骨点。截骨时,用大量生理盐水冲洗该部位。采用常规钻孔和骨环钻制备直径3.6 mm、长度11.5 mm的截骨点。用于准备截骨部位的牙槽扩张器尺寸为3.5mm,这是目前最接近的尺寸。温升是用热电偶温度计测量的。采用重复测量方差分析和Fisher最小显著性差异两两比较检验进行统计学分析。结果:重复测量方差分析显示,常规钻头、环钻和牙槽扩张器的产热差异显著(p结论:与牙槽扩张器和常规钻头相比,环钻产热最大。如果要使用环钻,必须同时使用内部和外部冲洗。在牙槽扩张器截骨术中产生较少的热量似乎是很有前途的,有利于更好的骨整合。

A comparative study to evaluate the heat generated during osteotomy with conventional drill, trephine and alveolar expander.

A comparative study to evaluate the heat generated during osteotomy with conventional drill, trephine and alveolar expander.

A comparative study to evaluate the heat generated during osteotomy with conventional drill, trephine and alveolar expander.

A comparative study to evaluate the heat generated during osteotomy with conventional drill, trephine and alveolar expander.

Purpose: Excessively produced heat could lead to clinical failure of osseointegration. This study was done to compare the heat generated during osteotomy with the conventional drill, trephine, and alveolar expander .

Materials and methods: This in vitro study was performed on ten bovine femoral bones. In each femoral bone, three osteotomy sites were prepared at a distance of 1.5cm using the conventional drill, trephine, and alveolar expander. During osteotomy, the site was irrigated with a copius amount of normal saline. Osteotomy sites of 3.6 mm in diameter and 11.5 mm in length were prepared using the conventional drill and bone trephines. The alveolar expander used for preparing the osteotomy site was 3.5mm, the nearest dimensions available. The temperature rise was measured using a thermocouple thermometer. Repeated measures ANOVA and Fisher's least significant difference pairwise comparison test was done for statistical analysis.

Results: Repeated measures ANOVA revealed a significant difference in the heat generation with the conventional drill, trephine, and alveolar expander (p<0.001). The mean heat generated was maximum with the trephine (28.26±0.246 0C) followed by the conventional drill (27.27±0.297 0C) and least with alveolar expander (25.64±0.142 0C). Pairwise comparison showed a significant difference in heat generated during osteotomy with conventional drill compared to trephine (P=0.023), conventional drill compared to alveolar expander (P=0.014), and trephine compared to alveolar expander (P<0.001).

Conclusion: The heat generated with trephine was maximum compared to the alveolar expander and conventional drills. If in case trephine is to be used, both internal and external irrigation must be used. Less heat generation during osteotomy by alveolar expander seems very promising and advantageous for better osseointegration.
