3-D scanning technology has become increasingly popular in recent years, and for good reason. Not only is it more comfortable for patients, but it also eliminates the need for messy impressions and puts less stress on the teeth. The key advantage of the procedure is that it does not require a physical impression. This implies that patients are not required to retain an unpleasant material in their mouths. Compared to tactile impressions, digital scans are also more accurate.
