Accuracy of digital surgical guides for dental implants

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.

Comparison the accuracy of a novel implant robot surgery and dynamic navigation system in dental implant surgery: an in vitro pilot study

“…A template-guided implant placement study revealed that implant insertion with a length of 8 to 9 mm resulted in significantly higher precision than insertion with lengths of 10 to 11 mm and 12 to 13 mm, although angle deviation was unaffected by implant length [ 25 ]. Similarly, a recent research has shown that there is a statistically significant difference in the deviation of the apical and cervical regions during implant placement, depending on the implant diameter and length, when using digital surgical guides for dental implants [ 26 ]. In order to reduce the influence of this aspect, we utilized the same implant diameter and length for each paired group.…”

Impact of 3D imaging techniques and virtual patients on the accuracy of planning and surgical placement of dental implants: A systematic review

“…Furthermore, the angular deviation between the planned and placed implants exhibited a variance of 3.42 ± 2.12°. 16 In evaluating factors influencing implant placement accuracy, statistically significant differences were observed in cases involving tissue-supported implant guide, implant diameter, and implant length. 48 Similarly, dynamic computer-aidedd implant surgery achieves an accuracy within a clinically acceptable range and exhibits potential for clinical implementation.…”

“…Moreover, these technologies have enabled the production of implant surgical guides through 3D printing, thereby enhancing the overall efficacy of dental implant procedures. 16 Augmented reality (AR) has progressively been applied in dental implant surgery, marking another dimension of technological integration. Nevertheless, the level of improvement in accuracy that can be achieved by integrating a dynamic navigation system with AR technology is currently unknown and requires further investigation.…”

Adjacent Implant Influence on Tooth Restoration in a Gastro-Esophageal Reflux Disease (GERD) Patient Using Monoblock Post-Fused Crown: A Case Report

“…Considering the patient's history of gastroesophageal acid reflux [11] and existing dental implants, the nearby prosthesis made of "all metals" could potentially lead to galvanism [13]. As highlighted by Kim SM (2023), contact between two different metal alloys in the presence of saliva initiates electrochemical reactions [13]. This phenomenon can result in galvanic erosion, additional soft tissue problems, tooth erosion, crown corrosion, and peri-implantitis [13].…”

“…As highlighted by Kim SM (2023), contact between two different metal alloys in the presence of saliva initiates electrochemical reactions [13]. This phenomenon can result in galvanic erosion, additional soft tissue problems, tooth erosion, crown corrosion, and peri-implantitis [13]. Therefore, in light of the patient's color preference, concerns regarding GERD, and the risk of galvanism, a monoblock post-fused porcelain crown was selected for this case.…”
