Abstract
Background: Recently developed imaging techniques, such as cone beam computed tomography (CBCT) and CAD/CAM technology, have facilitated reliable implant planning and implant surgical guide production by 3D printing. This study compared the accuracy of implant-guided surgery using the R2GATE® program with CBCT before and after surgery.
Patients and methods: The study included patients who visited the Department of Oral and Maxillofacial Surgery at Chonnam National University Hospital from September 2021 to March 2022. Twenty-four implants were placed in eleven patients. Using R2GATE® Windows (Megagen implant, Daegu, Korea) software, implant placement was planned. The difference was measured by the CBCT before and after surgery. The cervical and apical distance and angular deviation of the implants were measured. Statistical analysis was performed using an independent t-test, Pearson correlation, and multiple regression analyses.
Results: The three-dimensional linear distance difference between the planned implant and the placed implant was 0.97?±?0.37 mm at the cervical and 1.13?±?0.36 mm at the apical. The difference in angle deviation between the planned implant and the placed implant was 3.42?±?2.12°. Among the variables affecting the accuracy of implant placement, a statistically significant difference was found when using a tissue-supported implant guide, implant diameter and implant length.
Conclusion: Based on these results, using the R2GATE® program is useful to use an implant digital surgical guide, and it will be used in various clinic.
