This study introduces a novel laser ablation technique for precise bone removal in oral maxillofacial surgery. This method enhances safety by automatically adjusting laser power, preventing tissue damage from frictional heat during dental implant procedures.

Area of Science:

  • Oral and Maxillofacial Surgery
  • Biomedical Engineering
  • Laser Dentistry

Background:

  • Mechanical instruments in oral surgery generate frictional heat, potentially damaging surrounding tissues despite cooling systems.
  • Dental implant rehabilitation in the oral and maxillofacial region requires precise bone removal techniques.

Purpose of the Study:

  • To develop and evaluate a novel concept for precise bone removal using laser ablation in oral maxillofacial surgery.
  • To enhance the safety and accuracy of bone preparation for dental implant procedures.

Main Methods:

  • A preoperative plan was created based on a dataset using bovine bone.
  • Laser ablation was performed using a navigation system, guided by the preoperative plan.
  • The laser power was programmed to automatically decrease near planned cavity borders and critical anatomical structures.

Main Results:

  • The developed concept enables precise bone removal and adjustment of laser power according to the preoperative plan.
  • The system demonstrated automatic reduction of laser power to safeguard anatomical structures.
  • This approach ensures bone removal without thermal damage caused by frictional heat.

Conclusions:

  • Laser ablation offers a safe and precise alternative to mechanical instruments for bone removal in oral maxillofacial surgery.
  • The integration of navigation systems and adaptive laser power control enhances procedural safety and accuracy for dental implantology.
