3D imaging and diagnosis in dentistry: pitfalls and manipulation tools
Hands-on course
23 Nov 2017, 09:00 – 18:00 The Royal Rose Hotel, Abu Dhabi Area of interest: General Dentistry

Course description

Over the last 10 years, 3D Cone Beam CT has rapidly gained a central position in dental diagnosis, next to the traditional 2D methods. The last generation of this 3D imaging technology delivers extremely high resolution images at very low dose which opens continuously doors to new indications.

However, as with any radiographic modality, it is extremely important to gain proper knowledge on its use since a certain dose is distributed to the patient. European recommendations have been established following the general principle, ALARA, as low as reasonably achievable, meaning that the CBCT user but also the referring dentist need to be aware of all parameters to improve image quality and dose for each individual clinical case. This means that there is a risk that the final diagnostic outcome may be insufficient, or worse, may be redundant at the expense of the patient.

In addition, even when obtaining high quality and correctly taken 3D images, there is a risk of misdiagnosis or inadequate treatment planning when manipulating such 3D information. Understanding the 3D data file and how to analyze this volume is one of the main pitfalls in the digital treatment workflow of the dental patient. But 3D analysis and 3D diagnosis are merely the first step in the process. Thorough knowledge of technology, including software tools, will enable subsequent virtual planning of the diagnostic case. It is thus necessary for dental practitioners to understand the basic concepts of 3D technology, the generated volumes and the 3D image analysis, which will be explained during this lecture, using several clinical cases.

Course objectives

  • To understand the principles of 3D imaging compared to 2D techniques
  • To understand radiation safety
  • To recognize when to prescribe CBCT scans
  • To know how to minimize radiation exposure
  • To be able to interpret basic dental CBCT images
  • To acquire technical skills on image processing

Hands - on

Partiipants will acquire basic diagnostic skill for analysis of dental CBCT volumes, 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, TMJ and airway analysis, optical scan fusion and implant planning.
