Use of electrosurgery or laser surgery in the presence of metallic implants has been implicated in generating heat-induced injury to peri-implant bone, with the subsequent loss of osseointegration. Studies involving lasers offer conflicting results, while in the case of the electrosurg, little research has been published supporting or refuting these claims. This study measured local heat effects created by use of a unipolar electrosurgical unit, a bipolar electrosurgical unit, and a neodymium:yttrium-aluminum-garnet (Nd:YAG) laser. Absolute temperature increase was measured during an in vitro uncovering surgical procedure performed with each unit. Analysis of variance for repeated measures was performed. Second, absolute temperature increase for each unit was compared with a theoretical clinical limit of a 10 degrees C increase. The findings suggest that use of the unipolar electrosurgical unit should be avoided, while judicious use of both the bipolar unit or the laser unit should produce temperature profiles well within clinical limits.
在存在金属植入物的情况下使用电外科手术或激光手术，被认为会对种植体周围骨产生热诱导损伤，进而导致骨结合丧失。有关激光的研究结果相互矛盾，而对于电外科手术，几乎没有发表过支持或反驳这些说法的研究。本研究测量了使用单极电外科设备、双极电外科设备和钕钇铝石榴石（Nd:YAG）激光所产生的局部热效应。在使用每个设备进行的体外翻瓣手术过程中测量绝对温度升高情况。对重复测量进行方差分析。其次，将每个设备的绝对温度升高与10摄氏度升高的理论临床限值进行比较。研究结果表明应避免使用单极电外科设备，而明智地使用双极设备或激光设备所产生的温度变化应在临床限值范围内。
