Larger cases, particularly edentulous cases, can inherently introduce errors and decrease accuracy. There are many reasons why this can happen, but generally, it revolves around human error. One thing we recommend at CAD-Ray is that you bring in the patient, seat the surgical stent, and take another CT scan. You can easily pick up error or more importantly, you can dramatically boost your confidence during the surgery that you are delivering very precise and accurate care.[videopress rxWIzayq w=”1200″ hd=”true”]
The video above is a quick demonstration of what you can visualize. You can even take a digital measuring tool and draw lines through the metal tube to verify that your path of draw for fixture placement is accurate. It is also important to make sure you have the surgical stent seated all the way and properly indexed. You can use the opposing dentition and have the patient bite down on cotton rolls during the scan to prevent the device from moving inadvertently.
We recommend you do this days before the proposed surgery, not the day of surgery, in case you need to make corrections.
