Cone Beam CT scans are used to determine the bone width and height in the planning for dental implants. This is a more accurate way to ensure that the implants can be well placed and important structures are avoided. Today, this is the gold standard for dental implant planning. In some dental software programs, the images can be loaded and the implants planned virtually. A stent is fabricated through the software and used for the surgery. This is known as guided surgery.
