Summary
Robotic computer-assisted implant surgery (rCAIS) offers superior accuracy for dental implants over static computer-assisted implant surgery (sCAIS). However, rCAIS involves longer surgery times and increased patient discomfort, necessitating careful consideration of trade-offs.
Area of Science:
- Dental Implantology
- Surgical Technology
- Computer-Assisted Surgery
Background:
- Static computer-assisted implant surgery (sCAIS) and robotic computer-assisted implant surgery (rCAIS) are emerging techniques for precise dental implant placement.
- Evaluating their comparative outcomes is crucial for optimizing clinical practice in restorative dentistry.
Purpose of the Study:
- To compare the accuracy, efficiency, and patient- and surgeon-reported outcomes of sCAIS versus rCAIS for single-tooth posterior edentulism.
- To provide data for informed clinical decision-making in implant dentistry.
Main Methods:
- A randomized clinical trial involving 36 patients undergoing posterior single-tooth implant restoration.
- Patients were allocated to either sCAIS (n=18) or rCAIS (n=18) groups.
- Implant placement accuracy was evaluated using cone-beam computed tomography (CBCT) by measuring deviations from the planned position. Surgery time and patient/surgeon feedback were also recorded.
Main Results:
- Robotic computer-assisted implant surgery (rCAIS) demonstrated significantly higher accuracy, with reduced coronal, apical, and angular deviations compared to static computer-assisted implant surgery (sCAIS).
- However, rCAIS procedures were significantly longer and associated with greater intraoperative patient discomfort.
- Surgeons reported easier site access with sCAIS, while procedure complexity and primary implant stability were comparable between groups.
Conclusions:
- Robotic computer-assisted implant surgery (rCAIS) offers superior accuracy in dental implant placement but at the cost of increased procedure time and patient discomfort.
- Static computer-assisted implant surgery (sCAIS) provides reliable accuracy with simpler operation and better adaptability.
- Clinical choices should weigh the enhanced accuracy of rCAIS against patient comfort, procedural efficiency, and resource allocation.
