Most people who have visited a dentist for a dental checkup are familiar with the process of getting a dental impression made.
The dentist uses an elastic material to make an accurate copy of a patient's mouth for diagnostic reasons or to create a mouth appliance.
However, some people find this particular dental care step to be uncomfortable. Boston patient Robert Green told WBZ-TV that the paste used to make a mold causes him to feel queasy.
Now, the use of lasers to do the work that dental impressions once did may be welcomed by patients such as Green, the news provider suggests.
As part of the procedure, a laser scans the teeth's surfaces and quickly produces a 3D holographic image of the patient's mouth.
This image is then sent to a laboratory, where a mold that can be used to make crowns, bridges and dental implants is fashioned out of polyurethane.
Dentist Dr Gordon Sokoloff explained that laser devices will "replace impressions as we know [them]." The process provides more dimensional stability than traditional impressions, he added.
