Scanning systems evaluated in PPR
September 30, 2015
The September issue of ADA Professional Product Review
, available online, includes an evaluation of the accuracy of six intraoral scanning systems.
Researchers at the University of Maryland Dental School, in collaboration with the ADA Science Institute, focused on the scanners' ability
to accurately scan a single molar abutment tooth in vitro.
"In order to help make a decision on which scanner to purchase, scanning accuracy is an important factor to consider, as it is a component in determining the quality of the final restoration," said evaluation co-researchers Drs. Gary Hack and Sebastian Patzelt in a statement. "Digital dentistry, in terms of optical impression making, is one of the most relevant topics discussed today in dentistry."
The evaluation found that, within the limits of its study, "all of the six investigated scanners produced clinically acceptable results in terms of accuracy. The small observed differences might be related to technological aspects of each device. Further, additional deviations can be expected in the oral environment due to saliva, blood and patient movements."
The current issue of PPR also includes a new feature called "Clinician's Corner: Diagnostic Challenge," a case study series that begins with a patient new to a practice who requests an emergency bridge repair and a safety checklist for dental equipment.
