Many periodontists use a 3D volume rendering technique that allows for the visualization and measurement of a patient’s bone density prior to the implant procedure. Measuring bone density during the initial implant exam is critical, as it determines the next steps of the procedure. If a patient has low bone density, they may need a bone grafting procedure before the actual implant can be placed. Today’s technology allows periodontists to conduct a painless scan, also called CBCT or cone beam computer tomography, to completely map out all the structures in a patient’s mouth. The 3D volume rendering technique is done to enable the doctor to accurately assess bone density without invasive procedures, and a 3D volumetric reconstruction gives the doctor the information needed to begin planning for bone grafting. The doctor can use the reconstruction to determine where the bone graft should be placed and how much bone will be needed.

3D volumetric reconstruction
3D volumetric reconstruction is a newer technology that can be used in a variety of applications, particularly in the medical field. The area of a patient’s body is scanned via CBCT, or cone beam computer tomography, and is a painless imaging procedure. The structures of the body are recreated with 3D imaging, allowing a doctor to completely visualize the area of the patient’s body and even take certain measurements that help better plan for surgical procedures or treatments. One application of 3-D volumetric reconstruction is periodontics. Placing dental implants without good imaging is difficult and reduces the patient’s chances of a good outcome. X-ray technology helps periodontists visualize a patient’s mouth structures to some degree, however, 3D volumetric reconstruction allows for full visibility. This enables a periodontist to measure bone density, assess the location of nerves, and choose the optimal placement for dental implants.
