Digital Impressions in Forest Hill, Toronto

In order to offer patients dental care services that meet our standards, your oral exam with Dr. Paul Deratnay can also include digital impressions. Digital impressions are dental scans taken with 3D scanning technology. 

The digital impression system captures the dentition with the use of polygons (triangles) and by that, it helps build up a highly accurate 3D image of the patient’s dentition. There are different ways of getting to a digital impression: either a desktop scanner scans a gypsum model to generate a digital model, or an intraoral scanner generates a digital impression directly from the patient’s oral cavity. Intraoral scanning creates digital replicas of teeth and gums, and displays the result directly on a computer or tablet screen. The dental specialist can then use these digital teeth impressions for assessing whether there is a problem, what it is, what treatment could be required, and communicating about all this with the patient.

Alginate is the most used material for traditional impressions. Even though the process of taking alginate impressions is not a painful medical procedure, patients do need to sit for multiple minutes or longer.
