Figure Lengend Snippet: Precision in thermocouple positioning and surgical cavity distance. (A) Precision measurement and operational effects of the femtosecond laser pulses control system during thermocouple hole positioning. The real-time monitoring system automatically identifies and locates the exact positions of the thermocouple holes, with the pink circles and coordinate data around each hole demonstrating the precision of the positioning, and (B) the positional relationship between the thermocouple holes and the surgical cavity, where the distance between the thermocouple holes and the cavity is precisely controlled at 0.5 mm. This demonstrates the system's high precision and reliability in performing delicate operations.

Figure Lengend Snippet: Temperature variations during laser pulses ablation and microstructural comparisons with mechanical drilling. (A) Temperature variation curve when conducting experiments on the exposed cortical bone surface using optimized laser pulse parameters, and (B) microstructural treatment differences between laser pulses and mechanical drilling through SEM observations. The upper part displays the debris generated by mechanical drilling, highlighting the additional tissue damage that physical cutting actions can cause. The lower part shows the results of laser pulses ablation, illustrating cleaner and more precise ablaton effects, reducing debris and debris generation during surgery, thereby providing a safer and more accurate technique for clinical implant cavity preparation.
