Use of Cone Beam Computed Tomography in Implant Dentistry

Abstract

The literature supports the use of CBCT in dental implant treatment planning particularly in regards to linear measurements, three-dimensional evaluation of alveolar ridge topography, proximity to vital anatomical structures, and fabrication of surgical guides. Areas such as CBCT-derived bone density measurements, CBCT-aided surgical navigation, and postimplant CBCT artifacts need further research. ICOI RECOMMENDATIONS: All CBCT examinations, as all other radiographic examinations, must be justified on an individualized needs basis. The benefits to the patient for each CBCT scan must outweigh the potential risks. CBCT scans should not be taken without initially obtaining thorough medical and dental histories and performing a comprehensive clinical examination. CBCT should be considered as an imaging alternative in cases where the projected implant receptor or bone augmentation site(s) are suspect, and conventional radiography may not be able to assess the true regional three-dimensional anatomical presentation. The smallest possible field of view should be used, and the entire image volume should be interpreted.

A Comparison of Micro-CT and Dental CT in Assessing Cortical Bone Morphology and Trabecular Bone Microarchitecture

“…In recent years, dental CT has been widely used in dental clinical practices mainly because dental CT is not only inexpensive and involves low radiation doses [18], [29], [30], but it also possesses higher spatial resolutions for precisely measuring bone shapes and contours than traditional computed tomography does. Hashimoto et al [31] indicated that both the magnification and distortion of dental CT are extremely small (error < 0.1 mm).…”

Does cone-beam CT alter treatment plans? Comparison of preoperative implant planning using panoramic versus cone-beam CT images

“…An adequate determination of the bone height is recommended for avoiding the potential risks of intrusion of implants into vital anatomical structures including nerves, blood vessels, and impacted or supernumerary teeth 17. The buccolingual width and angulation of the available bone are the most important criteria for implant selection and success.…”

Conditions and calibration to obtain comparable grey values between different clinical cone beam computed tomography scanners

“…10,11 As the BMD can be measured by non-destructive X-ray-based technology, it is also utilized to diagnose bone disease and estimate bone quantity and quality of dental implantation sites in the clinical settings. 6,12,13 Bone is a heterogeneous material consisting of minerals on a collagen matrix. 14,15 The composition of bone changes by modelling and remodelling processes, which are activated at different time points.…”

“…[1][2][3][4][5][6] As the CBCT is an X-ray-based device, the dense materials of hard tissues (i.e. bone and tooth) absorb more radiation energy than soft tissues (i.e.…”
