An intraoral scanner is a handheld electronic device which can be inserted into the patient’s mouth to map the anatomical structures within the buccal cavity. The images are sent to a PC where they give a 3-dimensional visual representation of the patient’s mouth, teeth, roots, gums and bones, as well as the nerves and airways. Scans can be sent in an instant to your dental laboratory if required, meaning the whole process is quicker, safer, more efficient and more comfortable for the patient than traditional x-rays or modelling.

An intraoral dental scanner records the 3D geometry of the mouth and associated structures accurately and precisely by casting structured light on the area to be mapped. The handheld device uses image sensors to capture areas of interest which are sent to and processed by associated software. A point cloud is constructed which is then further interpreted by the software to create a virtual 3-dimensional surface model which is typically called a ‘mesh’.

The obvious factors are accuracy, speed, flexible workflows and an open system. But just as important is the quality of the software and the options it presents in terms of how scanned images are displayed – can they be easily understood by patients for educational purposes and to enhance customer satisfaction and approval of treatment options? You should also make sure your scanner is fully integrable with other technologies you use in your practice and with any external lab you use. Factor ongoing maintenance and repair costs into your budget; and ensure your staff on board with the technology and willing to learn how to use it before investing in an intraoral scanner.
