Summary
A passive Robot Arm (3D method) shows improved accuracy in orthognathic surgery model planning compared to traditional manual techniques. This robotic approach enhances precision in all three dimensions for better surgical outcomes.
Area of Science:
- Orthognathic surgery
- Surgical planning
- Robotic surgery
Background:
- Model surgery is a critical step in orthognathic surgery planning.
- Traditional manual techniques for model surgery have limitations in precision.
- Advancements in robotic technology offer potential improvements in surgical accuracy.
Purpose of the Study:
- To evaluate the accuracy of a passive Robot Arm (3D method) for model surgery in orthognathic procedures.
- To compare the precision of robot-assisted model surgery with the conventional manual technique.
- To determine the efficacy of robotic assistance in achieving planned surgical outcomes.
Main Methods:
- Seventeen patients undergoing orthognathic surgery participated.
- Model surgery was performed using both a manual technique (Group A) and a passive Robot Arm (Group B).
- Maxillary casts were measured pre- and post-model surgery and compared to the original treatment plan across X, Y, and Z axes.
Main Results:
- Statistical analysis revealed significant differences between the groups in the X-axis (P=0.026) and Y-axis (P=0.021).
- No significant difference was found between the manual and robotic techniques in the Z-axis (P=0.762).
- The Robot Arm demonstrated higher accuracy in the horizontal and vertical planes.
Conclusions:
- Model surgery performed with a passive Robot Arm is more accurate than manual model surgery.
- Robotic assistance in model surgery offers enhanced precision for orthognathic procedures.
- The 3D method using a Robot Arm shows promise for improving surgical planning accuracy.
