Abstract
Statement of problemThe accuracy of implant placement is a prerequisite for prosthetically driven implant surgery and is necessary to ensure the long-term stability of dental implants. Imprecise implant position may bring difficulties for restoration, damage anatomic structures, affect peri-implant tissues, and lead to ultimate implant failure. PurposeThe purpose of this retrospective clinical study was to compare the accuracy of implants placed with an autonomous dental implant robotic (ADIR) system with those placed with static computer assisted implant surgery (sCAIS). Material and methodsThirty-nine participants were enrolled in this retrospective study: 20 participants had received implant surgery with the ADIR system and 19 participants had implants placed with sCAIS. The preoperative plans and postoperative cone beam computed tomography (CBCT) scans after implant placement were matched during the study. The coronal, apical, and angular deviations were measured and analyzed. A linear regression model was established to analyze the source of deviation. MANOVA was used to compare differences in the major outcome variables (α=.05). ResultsA total of 60 implants were placed in 39 participants (30 in each of the 2 groups). The mean ±standard deviation coronal, apical, and angular deviation of the ADIR system group and sCAIS group were 0.43 ±0.18 mm versus 1.31 ±0.62 mm (P<.001), 0.56 ±0.18 mm versus 1.47 ±0.65 mm (P<.001), and 1.48 ±0.59 degrees versus 2.42 ±1.55 degrees (P=.003), respectively. In addition, there was no significant difference in accuracy in the different implant regions (anterior, premolar, molar, maxilla, mandible) (P>.05). No complications were observed. ConclusionsThe accuracy of the implant position using the ADIR system was significantly higher than with sCAIS, suggesting that the ADIR system can achieve minimally invasive and excellent accuracy. In addition, implant regions had no significant influence on the accuracy of implant placement. (Keywords: Robotic system, Implant surgery, Static guide, Autonomous, Accuracy)
