A CT-scan provides more detailed information about the position of wisdom teeth and their proximity to nerves and sinuses. While not indicated routinely for wisdom teeth, this type of image is helpful for patients who have severe or deeply impacted wisdom teeth and when your dentist is concerned about proximity to nerves, sinuses, or cysts. Although rare, any irritation to the nerve that passes under the lower wisdom teeth, can lead to a period of numbness along the lip and chin area. In most cases, this condition is temporary and resolves gradually in six to eight weeks. Only in rare instances, it may become more prolonged or permanent. Recently, cone beam CT-scan (CBCT) machines like I-CAT have become more readily available in dental offices. With less cost and significantly less radiation, CT-scan is being used more often instead of a panoramic X-ray. The i-CAT Cone Beam 3D Dental Imaging System allows us to provide quick, comfortable, and effective dental imaging for a precise wisdom teeth diagnosis. i-CAT special features include:8 or 23 second scan that provides enough data for a complete all-on-4 treatment, A safer diagnosis with less radiation than traditional CT scanners, Increased comfort - patients are seated in an open environment with plenty of space, A more cost-effective imaging system, We can easily share the data with patients, so patients stay informed and are able to make educated decisions on their course of treatment.
