Latest Digital Dental Technology
The i500 system is a dental 3D scanner intended to be used to digitally record topographical characteristics of teeth and surrounding tissues. The i500 system produces 3D scans for use in computer-aided design and manufacturing of dental restorations.

A crucial distinction to other intraoral scanners is that MEDIT i500 offers a complete CAD/CAM workflow with associated design software and CAD integration through its chair side software. 

Advanced technology, proven result

Zoom Whitening is the most popular professional dental whitening brand. Philips Zoom WhiteSpeed delivers maximum results with its advaced LED light-activated technology and variable intensity settings. It whiten teeth up to eight shades in one procedure.

One Scan, Two Images
We are equipped with 3D CBCT X-Ray, which is a game changer in dental radiographic imaging. The additional information we get with 3D image is invaluable. Seeing things in three dimensions greatly increases understanding of the problem for patients also. Patients now can co-diagnose their issues and treatment needs with a dentist watching both 2D and 3D images on a monitor comfortably seating on a patient chair.
