- To understand the principles of 3D imaging compared to 2D techniques in implantology
- To understand radiation safety and when to prescribe CBCT scans
- To know how to minimize radiation exposure in implantology
- To be able use basic and advanced image manipulation tools for implant diagnosis
- To acquire technical skills on digital impressions and optical scan fusion
Participants will acquire basic diagnostic skill for analysis of dental CBCT volumes, in the field of implantology, by practicing several clinical cases in a software on computers. Different analysis and segmentation tools will be explained and practiced in the software, including panoramic reconstructions, nerve and tooth segmentation, optical scan fusion and implant planning. In addition, a hands-on of optical scanning with focus on scanning ergonomy will be part of the course.
Over the last 10 years, 3D Cone Beam CT has rapidly gained a central position in dental diagnosis, next to the traditional 2D methods, especially in implant dentistry. The last generation of this 3D imaging technology delivers extremely high resolution images at very low dose which allows us to safely plan dental implants.
However, without proper understanding of 3D imaging technique, overexposure of our patients is once more at risk. It is thus extremely important to gain proper knowledge on its use and follow the proper guidelines to keep the doses ALARA, as low as reasonably achievable. Furthermore, the risk of misinterpretation has increased with 3D volumes, given the large amount of data and tremendous amount of software tools, so it is imperative for clinicians to gain proper knowledge and understanding of 3D datasets and their manipulation to obtain a proper 3D implant planning environment.
It is therefore the objective of this course to cover the basic diagnostic tools and the complete virtual implant treatment workflow and depict where the several pitfalls may lead to inaccuracy or worse to incorrect treatments. Using several clinical cases, the practitioner will gradually learn how to use 3D software tools for basic and more advanced implant planning, including the transfer by means of surgical guides.

Part 1: 09: –12:30 | CBCT analysis in implantology
In this first part, the lecturer will teach the basic skills on how to manipulate 3D CBCT datasets, this focused on the field of implantology. Both Small and Large field CBCT cases will be manipulated in this part, which will be present in a software platform on the computers. The lecturer will first show how a 3D CBCT software platform is organized, and which are the tools to go through the different planes (axial; sagittal; coronal).Basic visualization tools like image enhancement tools will be show, followed by more advanced analysis tools like interactive MultiPlanarReformatting of images and the reconstruction of panoramic overview images from the volume. The candidates will themselves after the demonstration, manipulate the volumes to practice basic skills. Documentation of cases using screenshots and annotations will be taught in this first part. Slowly more advanced tools like segmentation of nerves and teeth will be taught to the students.
Part 2: 13:30 – 18:00 | Virtual patient in implantology
After basic skill adoption, the candidates will progressively be introduced to more advanced tools like segmentation of nerves and the fusion of optical or digital impressions with the CBCT volume. A hands-on focused on digital impressions will also be included to give dentists the tips and tricks how to adopt adequate ergonomy for fast optical scanning. The students will then manipulate themselves the images to create more complex implant treatment environments, with the introduction of guide design for the transfer of the implant planning.
