Three-dimensional Positional Accuracy of Dental Implant Placement Using a Haptic and Machine Vision Controlled Collaborative Surgery Robot: a Pilot Randomized Controlled Trial

For free hand dental implant placement, a key difficulty is to accurately control the position. Improving precision of dental implant placement is considered important for safety and efficacy of tooth replacement with dental implants. In particular, more precise implant placement is expected to yield a better restoration both in terms of aesthetics and ability for self-performed oral hygiene and thus prevention of peri-implant diseases. The goal of this randomized controlled trial is to compare the positional implant accuracy, and patient reported outcomes comparing two methods of implant placement: the use of a robotic assisted surgery and freehand surgery. Patients requiring single tooth replacement with a dental implant will be digitally planned using a CBCT and an intraoral digital scan. Subjects will be randomized to one of the two treatment modalities based on the plan. The accuracy of placement will be assessed evaluating the difference between the planned and the actual position using a CBCT immediately after surgery. Subjects will be followed up for one year to assess both patient reported and professional outcomes.
