Surgical stents are designed in the same manner as a scanning appliance with the exception that radiopaque markers are not needed. In fact, most surgeons simply modify their CT stent and use it during surgery. Surgical stents can be modified in many ways. For example, some surgeons prefer occlusal coverage over the existing teeth, while others want the appliance to have full palatal coverage.
