Surgical Robot or Static Guide for Dental Implant Placement
Comparison of Robotic and Static Guide Assisted Surgery for Rehabilitation of Monolateral Distal Extension Edentulism With Implant-supported Fixed Partial Dentures: a Multicenter Randomized Controlled Trial.
Precision in implant placement is a key requirement for safety and to support the long-term success of dental implants.
Optimal placement requires implementing a diagnostic standard that includes careful digital planning based on CBCT and intraoral scanning data.
Once the case is planned, adherence to the plan during surgery cannot be achieved through freehand surgery; guidance is needed.
Guidance has two key components: real-time tracking of osteotomy site preparation (achieved with dynamic navigation technology) and constraining instrumentation to the planned site (achieved through the application of a surgical template that guides the position and direction of bone drilling).
Robotic surgery enables both objectives: real-time monitoring and guidance.
Previous studies have shown high precision for both static guidance and robotic surgery, but the evidence is limited to a few small-sample-size studies, mostly in single-tooth gap applications.
Evidence of the applicability of the technologies to more challenging clinical conditions, such as the more complex distal extension, is lacking.
In addition, so far, dental implant robotics studies have focused only on metrics of implant placement precision and have failed to capture a broader context that may be equally important for clinical decision-making and patient preferences.
In this respect, it is important to emphasize the recent implant dentistry core outcome set and measurement (ID-COSM) framework that mandates capturing and reporting a full range of outcomes across multiple domains.

Degrees of Implant misangulation
기간: 3 months after implant surgery
|
The implant position was acquired 3 months after implant surgery with an intraoral scan (TRIOS 3; 3Shape) with a scan body in place.
The actual position was compared with the digital plan by the accuracy analysis software (DentalNavi 2.2; YakeRobot Technology Ltd) by an independent calibrated examiner blind to group allocation.
The discrepancy between planned and actual implant axis angulation will be measured in degrees.
