Parameter Optimization of Ultrafast Laser for Dental Implant Cavity Accurate Preparation
Objectives: To optimize the ultrafast laser parameters and to predict and control the temperature of three-dimensional accurate ablation of bone and soft tissues for implant cavity preparation by robot surgery system controlled through multivariate polynomial models.
Methods: The femtosecond laser was controlled by the robot surgery system to three-dimensional accurate ablate the tibia and soft tissue of sheep for implant cavity preparation in vitro experiments, the temperature of implant cavity was monitored in real time by the thermocouple sensor, and the multivariate polynomial model was used to analyze, predict and control the laser parameters and temperature changes. The implant cavities were observed by electron microscopy technology to evaluate the effect of implant cavity.
Results: The ultrafast laser surgery system controlled by the robot was used to integrate three-dimensional accurate ablation soft and hard tissues (including bone tissue with a thickness of 2mm soft tissues), and implant cavities with a diameter of 4mm and a depth of 6mm was prepared. The operating parameters predicted by the multivariate polynomial model maintained the average temperature at 39.85°C, with a temperature fluctuation range of 5.3°C, and ensured that the maximum temperature was controlled within 42.5°C to meet clinical safety requirements. Scanning electron microscopy (SEM) confirmed significant improvements in the quality of the implant cavities prepared using the femtosecond laser pulses. The high degree of agreement between the model prediction and the actual measurement data further proves the effectiveness of the temperature control strategy.
Conclusions: The ultrafast laser surgery system controlled by the robot enhances both precision and safety in automated implant cavity preparation, significantly reducing thermal damage to surrounding tissues. In this study, the surgical outcome was improved by precisely optimizing the laser pulse parameters. The robot-controlled ultrafast laser surgery system has great potential and broad application prospects in dental implant and bone tissue surgery.
