Given the higher resolution, lower radiation dose, and lower cost of CBCT in imaging the maxillofacial region, it stands to reason that CBCT can easily replace conventional CT in this regard. Three-dimensional imaging of cysts and tumors of the maxillofacial region can give the surgeon the vital information necessary for planning surgery; volumetric analysiscan help anticipate the need for and the volume of a potential graft for reconstruction.
The diagnosis and treatment planning of temporomandibular joint (TMJ) disorders often are quite challenging. Although magnetic resonance imaging remains the gold standard for imaging the intra-articular components of the TMJ, CBCT is shown to provide a complete three-dimensional radiographic evaluation of the bony components of the TMJ, eliminating the need for conventional radiography.
CBCT has recently been applied with significant impact to orthognatic surgery. It allows for the fabrication of intermediate and final splints to be used during surgery. An extended field of view CBCT of the patient is obtained. With it, an anatomically accurate virtual representation of the patient can be created. Based on the cephalometric analysis, virtual surgery can be performed on the virtual model, accurately planning the movements and seeing the actual results instantly. With the virtual surgical movements finalized, intermediate and final splints can be milled off the virtual models and shipped out to the surgeon. The splints are precise, accurate, and ready for use during the actual surgery.
The identification, treatment planning, and evaluation of potential complications of impacted teeth are greatly improved by adding the third- dimension through CBCT. The relationship of impacted third molars to the mandibular canal, adjacent teeth, sinus walls, and cortical borders is important diagnostic information that can directly impact the outcome of surgery.
Using CBCT to locate and evaluate impacted cuspids and supernumerary teeth seem to make the surgical procedure more efficient and less invasive. Because the anatomic structures adjacent to the region of interest can be seen in theee-dimensions, this additional information may reduce complications during surgery, contributing to a better outcome.
In our practice, the use of CBCT has revolutionized the way we approach our patients. There is no guessing game when it comes to treatment planning. The ability to show our patients the radiographic information in three-dimensions allows for a comprehensive conversation and understanding in part of the patient, surgeon, and restorative team. We are very excited to be able to offer your patients this option and are here to assist your practice in any way we can.
