Summary
Robotic-guided surgery offers the highest accuracy for dental implant placement, surpassing optical dynamic navigation and conventional freehand methods. While surgical time is longer, robotic and navigation systems significantly reduce early complications compared to freehand techniques.
Area of Science:
- Dental Implantology
- Surgical Navigation Technologies
- Medical Robotics
Background:
- Accurate 3D implant positioning is crucial for successful prosthodontic outcomes and patient safety in implant dentistry.
- Minimizing risks to adjacent anatomical structures is a key consideration in implant placement.
- Conventional freehand techniques may present challenges in achieving precise implant positioning.
Purpose of the Study:
- To compare the accuracy and clinical outcomes of robotic-guided (RG) surgery, optical dynamic navigation-guided (ONG) surgery, and conventional freehand (CF) surgery for single delayed dental implant placement.
- To evaluate secondary outcomes including operative time, postoperative pain, patient satisfaction, and early complications.
Main Methods:
- A prospective randomized comparative study involving 180 adult patients undergoing single delayed implant placement.
- Patients were allocated to three groups: RG surgery (n=60), ONG surgery (n=60), and CF surgery (n=60).
- Implant accuracy was assessed by superimposing preoperative and postoperative cone-beam computed tomography (CBCT) scans to measure deviations (angular, apical, coronal, depth).
Main Results:
- Robotic-guided surgery demonstrated the highest accuracy, with the lowest mean angular deviation (1.82°±0.64°), followed by ONG (2.34°±0.89°) and CF (4.87°±1.53°; p<0.001).
- Apical and coronal deviations followed the same pattern, indicating superior precision with RG and ONG.
- Early complications were significantly less frequent in the RG (3.4%) and ONG (6.8%) groups compared to the CF group (15.5%; p=0.042), despite longer surgical times for RG.
Conclusions:
- Robotic-guided surgery achieved the highest accuracy in dental implant placement within the study's limitations.
- Optical dynamic navigation offers a clinically significant improvement over conventional freehand placement.
- Further research is needed to evaluate long-term survival rates, prosthetic outcomes, and cost-effectiveness.
