Abstract
The present article describes a dental implant planning workflow to solve the CBCT artifact problem. The technique uses a radiopaque 3D-printed tray to take impressions and complete data alignment of the dental arches where implants are planned. From the impressions, 3D Boolean inversion is performed to obtain the surface mesh of teeth and virtually remove the undercut of dentition mesh before an implant surgical guide is designed. The trueness and precision of 3D alignment are then compared with the original radiographic template alignment using the double-scan method. In the present study, the results showed that this method could improve alignment trueness and allow for the elimination of radiographic template making, reducing patient visits and making possible a same-day guided implant surgery.
期刊介绍：
This journal explores the myriad innovations in the emerging field of computerized dentistry and how to integrate them into clinical practice. The bulk of the journal is devoted to the science of computer-assisted dentistry, with research articles and clinical reports on all aspects of computer-based diagnostic and therapeutic applications, with special emphasis placed on CAD/CAM and image-processing systems. Articles also address the use of computer-based communication to support patient care, assess the quality of care, and enhance clinical decision making. The journal is presented in a bilingual format, with each issue offering three types of articles: science-based, application-based, and national society reports.
