The excessive temperature fluctuations during dental implant site preparation may affect the process of bone-implant osseointegration. In the presented studies, we aimed to assess the quality of cooling during the use of 3 different dental implant systems (BEGO®, NEO BIOTECH®, and BIOMET 3i®). The swine rib was chosen as a study model. The preparation of dental implant site was performed with the use of 3 different speeds of rotation (800, 1,200, and 1,500 rpm) and three types of cooling: with saline solution at room temperature, with saline solution cooled down to 3°C, and without cooling. A statistically significant difference in temperature fluctuations was observed between BEGO and NEO BIOTECH dental systems when cooling with saline solution at 3°C was used (22.3°C versus 21.8°C). In case of all three evaluated dental implant systems, the highest temperature fluctuations occurred when pilot drills were used for implant site preparation. The critical temperature, defined in the available literature, was exceeded only in case of pilot drills (of all 3 systems) used at rotation speed of 1,500 rpm without cooling.
牙种植体植入部位制备过程中温度波动过大可能会影响骨-种植体骨结合过程。在本研究中,我们旨在评估使用3种不同牙种植系统(BEGO®、NEO BIOTECH®和BIOMET 3i®)时的冷却质量。选用猪肋骨作为研究模型。使用3种不同的旋转速度(800、1200和1500转/分钟)以及3种冷却方式进行牙种植体植入部位的制备:使用室温生理盐水、冷却至3°C的生理盐水以及不进行冷却。当使用冷却至3°C的生理盐水进行冷却时,观察到BEGO和NEO BIOTECH牙种植系统之间的温度波动存在统计学显著差异(22.3°C对21.8°C)。对于所有三种评估的牙种植系统,当使用导向钻进行种植体植入部位制备时,温度波动最大。仅在不进行冷却、以1500转/分钟的转速使用导向钻(所有3种系统)的情况下,超过了现有文献中定义的临界温度。
