How to determine bone quality in CBCT
Author Reinhilde Jacobs
This is an inactive lesson for testing
Authors Nikolaos Donos , Jay ELLIOTT
To earn CE credits a lecture has to be watched completely and the referring exam needs to be passed. An exam is passed if at least 70% of all answers are correct.
After achievement a personal certificate is issued. It is valid 1 year. The certificate is anytime retrievable in the „My certificates“ area on Dental Campus.
The exam can be repeated 4 times. Each re-examination can be taken after anytime.

Learning objectives
After completing this module you should be able to:
- Determine the clinical indications for a CBCT in implant dentistry and decide in which specific situation the use of a CBCT is justified
- Know the guidelines for the use of CBCT in dental and maxillofacial radiology and find additional online resources on CBCT guidelines
- Describe the technical principles of a CBCT
- Understand the dosimetry of a CBCT in comparison with conventional CT scans
- Explain how the following factors influence radiation dose and image quality: voxel size, patient position, field of view, pulsed or continuous radiation, patient movement, metals in the oral cavity, detector type, parameter settings (mAs, kV), reconstruction algorithm
- Position the patient correctly and set the multiplanar reformatting spline (curve that serves as a basis for panoramic view and cross-sectional images)
- Interpret CBCT data correctly and recognize errors and artifacts
- Recognize proper anatomy and pathology in CBCTs and find other important online learning resources on CBCT anatomy and pathology
- Determine bone quality and quantity with CBCTs by relative Hounsfield values
- Link local and systemic bone quality to implant success
- Be aware of the possibilities of anatomical models based on CBCT data and know about their accuracy
- Discuss the possibilities and limitations of CBCT
