Intraoral scanning bests conventional impression in improving patient reported outcomes: Study

The results of the study are as follows:

Seventeen studies were selected for qualitative synthesis.

· The 17 included studies provided data from 430 IOS and 370 CI performed in 437 patients.

· A total of 7 different IOS systems and their various updated versions were used for digital impressions.

· The results demonstrated that IOS was overall faster than CI independent of whether quadrant or complete-arch scanning was utilized, regardless of the nature of the restoration (tooth or implant-supported).

· IOS was generally preferred over CI regardless of the size of the scanned area and nature of the restoration (tooth- or implant-supported).

· Similar prosthodontic outcomes were reported for workflows implementing CI and IOS.

Thus, the researchers concluded that Within the limitations of this systematic review, IOS is faster than CI, independent of whether a quadrant or complete arch scan is conducted. IOS can improve the patient experience measured by overall preference and comfort and is able to provide reliable prosthodontic outcomes.
