(NVision: Coppell, TX) -- NVision Inc., a leader in 3-D noncontact optical scanning for more than 21 years, recently provided an orthodontic company with the information it needed to recalibrate its CT scanner. The company, an orthodontic supplier, used NVision’s Engineering Service Division to scan a human skull as part of the verification and inspection process for its in-house CT machine. The scanning results provided by NVision contained all the measurement data necessary for the orthodontic company to recalibrate its CT machine to the highest possible level of accuracy.

The use of CT scans in orthodontics has increased in recent years, primarily because such scans can provide practitioners with an enhanced view of a patient’s facial anatomy. Unlike traditional 2-D X-rays, CT scans provide a 3-D image of the patient’s skull, teeth, roots, and jaw that can be viewed from all angles, providing extra information that can’t be obtained solely with X-rays. This information can aid orthodontists and oral surgeons in diagnosing problems and planning treatment (figure 1).
