DentiiScan is the first dental cone-beam CT scanner that has been researched and developed in Thailand by Thai researchers from the National Electronics and Computer Technology Center (NECTEC) and the National Metal and Materials Technology Center (MTEC) under the National Science and Technology Development Agency (NSTDA), Thailand. DentiiScan provides 3D information of anatomical structures without superposition and distortion, unlike conventional 2D X-ray images. It is widely used for diagnosis and treatment planning in dental and maxillofacial applications, such as dental implant placement, maxillofacial surgery, impacted tooth extraction, orthodontics and jaw cysts. Not only for dental applications, DentiiScan can be applied for other applications, such as implant-supported auricular prosthesis and acute sinusitis. Furthermore, DentiiScan provides less radiation doses to a patient than typical medical CT scanners. DentiiScan has already passed the radiation safety test from the Department of Medical Sciences, Ministry of Public Health; and the machine safety test from the Electrical and Electronic Product Testing Center (PTEC). DentiiScan received the ethical approval from the national ethics committee by the Institution of the Development of Human Research Protections (IHRP), Ministry of Public Health to test on volunteer patients and the testing was completed.
