Many inserted implants are affected by peri-implantitis. The aim of our study was to evaluate increases in implant temperature, depending on the diameter and chemical composition of implants. In particular we measured the time it takes for the temperature of an implant to rise by 10°C and evaluated laser power settings required to prevent thermal injury when an implant surface is decontaminated during the treatment of peri-implantitis. The study analysed six implants placed in porcine ribs and divided into two groups according to their diameter and chemical composition (grade IV and grade V titanium). The implants were irradiated with Diode and Er:YAG lasers using different laser parameters. The temperature was measured with a K-type thermocouple. The temperature on the implant surface rose as the laser power increased and the implant diameter decreased. The time required to increase the temperature of an implant by 10°C was less than it was for titanium grade IV. The temperature gradient was below 10°C for all implants treated using a laser power up to 1 W. It is important to choose the correct laser parameters, depending on the chemical composition and diameter of the implant, so that decontamination of the implant surface is thorough, effective and safe.
许多植入的种植体都会受到种植体周围炎的影响。我们研究的目的是评估种植体温度的升高情况，这取决于种植体的直径和化学成分。具体而言，我们测量了种植体温度升高10°C所需的时间，并评估了在治疗种植体周围炎期间对种植体表面进行去污时防止热损伤所需的激光功率设置。该研究分析了植入猪肋骨的6个种植体，并根据其直径和化学成分（IV级和V级钛）分为两组。使用不同的激光参数，用二极管激光和铒:钇铝石榴石激光对种植体进行照射。用K型热电偶测量温度。随着激光功率的增加和种植体直径的减小，种植体表面的温度升高。种植体温度升高10°C所需的时间比IV级钛种植体要短。对于所有使用高达1W激光功率治疗的种植体，温度梯度低于10°C。根据种植体的化学成分和直径选择正确的激光参数很重要，这样才能使种植体表面的去污彻底、有效且安全。
