title: [Heat distribution within the bone tissue by rotary cutting instrument for IMZ implant. Heat analysis by a real-time thermography].
abstract: A highly skilled surgical technic is an important factor for the success of implant. But the heat generation during bone preparation will greatly affect the healing process of bone and prognosis of implant. In this study, the heat occurrence and distribution during bone preparation which performed on an in vitro mandible model (ribs of pig) were considered with the aid of a real-time thermography. IMZ implant drills and bur, designed for cylindrical type implant were used for the bone preparation. The conclusion are as follows: 1. Any drill or bur generates higher heat without water irrigation. 2. Heat distribution produced different shape of range according to different type of drills. 3. On a relationship of preparating time to heat generation, spiral drill takes the longest time to complete drilling but heat rising ratio is slow. Round bur and Canon drill take short time to complete drilling but it is accompanied with rapid heat rising.
