This study compares the heat generated during bone drilling using different protocols and implant systems, first in vitro and then in vivo with an animal model. In the experimental phase, thermal data were collected using an infrared camera while preparing implant beds in bone similes. The heat generated by a one-drill protocol with a new-generation drill bit and the Straumann BLT sequential drilling protocol was evaluated. The experimental study was then replicated in an animal model to assess the impact of these protocols on early osseointegration, measured by bone-to-implant contact (BIC) at three weeks post-surgery for Straumann BLT SLActive and Medentika Quattrocone implants. The results showed the BLT sequential protocol generated significantly more heat during drilling in bone similes compared to the new-generation drill bit. In the animal model, a histological analysis revealed a trend favoring shorter drilling protocols, with reduced drilling times and a potential advantage for osseointegration, though the BIC differences were not statistically significant. These findings suggest that minimizing the number of drilling steps and thermal stress may enhance osseointegration more effectively than advanced implant surface treatments. This aligns with emerging views on the importance of optimized drilling protocols and designs to reduce heat generation and better preserve surrounding bone structure.
本研究比较了使用不同方案和种植体系统进行骨钻孔时产生的热量，首先在体外进行，然后在动物模型中进行体内实验。在实验阶段，在骨模拟物中制备种植窝时，使用红外热像仪收集热数据。评估了使用新一代钻头的单钻孔方案和士卓曼BLT顺序钻孔方案产生的热量。然后在动物模型中重复进行实验研究，以评估这些方案对早期骨整合的影响，通过术后三周时士卓曼BLT SLActive种植体和Medentika Quattrocone种植体的骨与种植体接触（BIC）来衡量。结果显示，与新一代钻头相比，BLT顺序方案在骨模拟物钻孔过程中产生的热量明显更多。在动物模型中，组织学分析显示出有利于缩短钻孔方案的趋势，即减少钻孔时间，对骨整合可能具有潜在优势，尽管BIC差异无统计学意义。这些发现表明，与先进的种植体表面处理相比，尽量减少钻孔步骤和热应力可能更有效地增强骨整合。这与关于优化钻孔方案和设计以减少热量产生并更好地保留周围骨结构的重要性的新观点一致。
