Since the late 1980s, CT was used for surgical planning in oral and maxillofacial surgery and early endosseous implant placement. 5 Since its introduction, CT imaging of the orofacial region has been of interest as a clinical tool. 5 CT was the first technology to allow visualisation of both hard and soft tissues of the facial bones through the ability to acquire multiple consecutive cross-sectional images. Technological advances in radiological imaging have led to the introduction of new 3D imaging methods in many fields of radiology, including dentomaxillofacial radiology. ![]() However, the evolution of diagnostics and treatment in different dental disciplines has raised the need for three-dimensional (3D) imaging to overcome anatomical overlap and distortions inherent to 2D radiology. 1,2 For routine diagnostics, these imaging modalities may often suffice. In dentomaxillofacial diagnostics, traditional radiologic examinations are usually limited to two-dimensional (2D) views such as intraoral and panoramic radiographies. Dentistry has witnessed tremendous advances over the past decade, with a shift towards digital dentistry, not only for diagnostics but also for surgical planning and treatment. ![]()
