Virtual apicectomy simulator training significantly improves surgical skills. Trainees demonstrated better preservation of vital structures and reduced bone removal in physical reality after virtual practice.

Area of Science:

  • Oral Surgery
  • Surgical Simulation
  • Medical Education

Background:

  • Apicectomy requires precise bone reduction to avoid damaging adjacent nerves and teeth.
  • Assessing the transferability of virtual surgical skills to real-world procedures is crucial for validating simulation training.

Purpose of the Study:

  • To evaluate the effectiveness of a virtual apicectomy simulator (VOXEL-MAN) in improving surgical skills.
  • To determine if skills learned in a virtual environment are transferable to physical apicectomy procedures.

Main Methods:

  • Two groups of trainees were compared: one receiving virtual training before a pig cadaver apicectomy, and a control group.
  • Performance was assessed by the probability of preserving vital structures and the volume of bony defects created.

Main Results:

  • Virtual surgical training led to a six-fold increase in the probability of preserving vital neighboring structures (P<0.001).
  • Trainees with virtual training created significantly smaller bony defects (0.25 ml) compared to the control group (0.47 ml) (P<0.001).
  • The ability for objective self-assessment of performance was significantly enhanced post-virtual training.

Conclusions:

  • Virtual apicectomy simulator training is effective in enhancing surgical precision.
  • Skills acquired through virtual simulation are transferable to physical apicectomy procedures, improving patient safety outcomes.
