Types of Technology

Cone Beam 3D Imaging

Cone beam computed tomography is an innovative medical imaging technique that provides orthodontists with 3D views of the patient. This can assist the doctors in being proactive with treatment.

Digital Impressions

Advanced scanners, like the iTero Scanner,  work by capturing thousands of pictures of your teeth and oral structures and assembling them into an incredibly precise 3D model in five minutes or less!


Invisalign is a discreet approach for mild to moderate teeth realignment. As you move from one aligner to the next, your teeth will gently straighten, allowing you the freedom to focus on other things.


SureSmile takes away the stress of uncomfortable treatment options and provides fast and efficient progress. Unlike normal braces, SureSmile’s advanced technology ensures precise results.

3D Printing

Our two in-house 3D printers make high-capacity and flexibility the main priority. This technology allows us to provide faster processes, serve our customers better and guarentee the best experience.
