Robot-Assisted Dental Implant Surgery Following Guided Bone Regeneration: A Clinical Case Report

Accurate placement of dental osseointegrated implants is critical for long-term success, with factors significantly influencing stability and integration with surrounding tissues (i.e., depth, angle, and positioning within the bone). Nowadays, dental surgeries assisted by implant robots are gaining popularity. This occurs because dental robots provide precise and accurate minimally invasive surgery.

A 46-year-old woman visited a private dental clinic with missing teeth in positions 4.5 and 4.6. Upon clinical and radiographic examination, severe ridge atrophy was observed. To address this, horizontal and vertical guided bone regeneration (GBR) was performed using a customized titanium occlusive membrane. After 6 months, DICOM files of the patients were imported into the robot implant planning software (RemebotDent, Remebot, Beijing Rui Yi Bo Technology DICOM Ltd., China) for the placement of two dental implants (CLC CONIC, CLC Scientific, Vicenza, Italy).

After the GBR procedure, vertical bone gain was on average 2 mm, whereas horizontal bone gain was 5.28 and 5.34 mm in the middle position of 4.5 and 4.6. The robot-assisted surgery revealed high accuracy, since the implants in positions 4.5 and 4.6 showed a coronal global deviation of 0.42 and 0.57 mm and angular deviation of 0.62° and 0.69°, respectively.

This robotic surgical system can offer high accuracy and reliability with the preoperative plan. The potential for future collaboration between robots and surgeons may significantly alter the landscape of implant dentistry, and further studies are needed to confirm the accuracy of robotic implant placement.
