Femtosecond laser pulses are employed in the preparation of implant cavities during dental implant surgeries in the field of digital dentistry, specifically focusing on optimizing laser pulse parameters to enhance precision and control thermal injury. In this study, experiments were conducted on sheep tibiae, where thermocouple sensors monitored the temperature variations during ablation. This approach aims to optimize the laser pulse parameters and control the temperature, ensuring smoother cavity margins and better preservation of the bone microarchitecture. Scanning electron microscopy (SEM) confirmed significant improvements in the quality of the implant cavities prepared using the femtosecond laser pulses.
在数字牙科领域的牙种植手术中，飞秒激光脉冲用于制备种植窝洞，特别注重优化激光脉冲参数以提高精度并控制热损伤。在本研究中，对绵羊胫骨进行了实验，实验中使用热电偶传感器监测消融过程中的温度变化。这种方法旨在优化激光脉冲参数并控制温度，确保种植窝洞边缘更平滑，更好地保留骨微结构。扫描电子显微镜（SEM）证实，使用飞秒激光脉冲制备的种植窝洞质量有显著改善。
