Implant planning using computed tomography

Abstract

The use of virtual images derived from tomography to plan and place osseointegrable implants is common in dental practice. Cone Beam Computed Tomography (CBCT) has become widely accessible due to its ability to provide three-dimensional images of anatomical structures with low radiation dose. This technique, when combined with planning software, allows for precise and non-invasive diagnosis, facilitating correct implant positioning. The advancement of 3D imaging in Dentistry, along with planning programs for guided surgery, has transformed implant diagnosis and treatment, improving outcomes for patients. A literature review study analyzed 17 articles published between 2010 and 2020, highlighting the advantages of CBCT. However, the technique is sensitive to patient movements, metallic artifacts, and specific device parameters, besides presenting higher radiation dose and cost compared to conventional radiographs. Implant positioning and abutment selection must be carefully planned with the aid of specialized software. Despite the observed benefits, further research is needed to refine this imaging method.
