Accuracy of Guided Implant Surgery Using an Intraoral Scanner and Desktop 3D-Printed Tooth-Supported Guides
Summary
Desktop 3D-printed guides offer accurate single-tooth implant placement. This study confirms their acceptable fit and precision for guided surgery, making it more accessible.
Area of Science:
- Dental Implantology
- Digital Dentistry
- 3D Printing Technology
Background:
- Desktop 3D printers are increasing accessibility to guided implant surgery.
- Tooth-supported guides offer a precise method for implant placement.
Purpose of the Study:
- To evaluate the accuracy of single-tooth guided implant surgery using a 3D-printed tooth-supported guide.
- To assess the fit and precision of desktop 3D-printed guides for dental implants.
Main Methods:
- Fifteen implants were virtually planned for a mandibular molar using Exocad software.
- A tooth-supported guide was designed and manufactured with a desktop 3D printer.
- Implants were placed in resin casts, and digital impressions were compared to virtual positions.
Main Results:
- Mean angular deviation was 2.63 degrees, with coronal and apical deviations of 0.52 mm and 0.90 mm, respectively.
- Internal guide fit averaged 79.5 μm.
- Accuracy was acceptable in buccolingual, mesiodistal, and vertical directions.
Conclusions:
- Desktop 3D-printed tooth-supported guides provide an acceptable fit.
- These guides demonstrate acceptable accuracy for single implant placement in guided surgery.
- The use of 3D-printed guides enhances the accessibility of guided implant surgery.
