The aim of this study was to measure the increase in temperature in dental implants during the intake of hot beverages in vivo.
Eight successfully osseointegrated implants in 7 subjects were examined. Each subject was asked to drink the same volume of hot beverage. While drinking, temperature changes were recorded via 3 embedded thermocouples placed (i) in the implant's internal space, (ii) at the implant-abutment interface, and (iii) at the abutment. All thermocouples were linked to a computer and analyzed with appropriate software.
The maximum temperatures were 47.3 degrees C at the abutment, 45.6 degrees C at the implant's internal space, and 44.6 degrees C at the implant-abutment interface. A linear correlation was found between the temperatures measured (i) at the implant abutment and in the implant's internal space, and (ii) at the abutment and at the abutment-implant interface.
Further clinical studies are required to determine whether the habitual consumption of hot food and beverages may be considered a risk factor in the success of implant-supported prostheses.
本研究的目的是测量在体内摄入热饮时牙种植体的温度升高情况。
对7名受试者体内8颗成功骨整合的种植体进行了检查。要求每位受试者饮用相同体积的热饮。饮用过程中，通过3个嵌入式热电偶记录温度变化，热电偶分别放置在：（i）种植体内部空间；（ii）种植体-基台界面；（iii）基台上。所有热电偶均连接到计算机，并使用适当的软件进行分析。
基台处的最高温度为47.3摄氏度，种植体内部空间为45.6摄氏度，种植体-基台界面为44.6摄氏度。在（i）种植体基台处和种植体内部空间所测量的温度之间，以及（ii）基台处和基台-种植体界面处的温度之间，发现存在线性相关性。
需要进一步的临床研究来确定经常食用热食和热饮是否可被视为种植体支持修复体成功的一个风险因素。
