3D is often preferable to 2D as it shows depth as well as height and width. With 2D there is always an element of guesswork as the exact location of structures cannot be determined. Whilst 2D images are perfectly adequate for evaluating tooth decay, bone loss and other more common dental issues, 3D is essential for more complicated procedures such as implant placement and endodontics.

It is possible to achieve extremely clear, high-definition images with a digital 3D imaging machine which gives the clinician all the information they need to effectively diagnose and plan treatment. The technology behind digital X-ray machines has advanced significantly to enable the capture of sharp, accurate representations of patients’ oral anatomy in both 2D and 3D.

The real game-changer in recent developments in 3D digital X-ray technology is the ability to capture 3D images at extremely low radiation doses. This has removed a common barrier for many clinicians who have discounted 3D images due to the higher radiation doses required.

Dental practices are required to adhere to both the Ionising Radiation (Medical Exposure) 2000 Regulations (IR(ME)R) and the Ionising Radiations Regulations 2017 (IRR17) , which are based on the ALARA principle of only exposing a patient to a radiation dose that is “as low as reasonably achievable.” As a rule, dental practitioners should favour a lower dose wherever practicable, as long as the resultant X-ray provides the detail and information required to make an accurate diagnosis and an effective treatment plan.

An accurate picture of the oral situation is key for diagnosis, especially for more complex treatment such as endodontics and implant surgery. For instance, it enables endodontists to determine much more easily the presence and location of disease and therefore decide upon the long-term prognosis of the tooth.

A clear 3D model of the oral anatomy enables clinicians to plan treatment much more effectively. Implant surgeons can determine the optimum placement and angle of the implant, taking into account bone density and the location of any nerves. Endodontists can accurately plan their access and ensure they know the number and configuration of root canals and the curvature of the roots. 3D removes the element of surprise.

From accurate diagnosis and comprehensive treatment planning comes efficient treatment. The clinician is ready with the requisite tools and materials to carry out a planned and optimised treatment and this leads to better patient outcomes. Having a CBCT scanner in-practice with both 2D and 3D capabilities, and a range of dosage and field of view options means the clinician is fully equipped to make the right treatment decisions in the shortest possible time frame - which benefits the patient and the business.
