Improved digital impressions of edentulous areas.

Intraoral scanners (IOSs) are widely used in the fabrication of fixed dental prostheses, in that their accuracy compares well with traditional impression making. Recently, IOSs have been successfully used in the fabrication of removable dental prostheses. Digital impressions are useful for patients with a gag reflex and sensitivity to impression materials. Moreover, IOSs can register excessively movable tissue in a passive state to achieve a mucostatic impression. However, scanning edentulous area with IOSs may be difficult and time-consuming, because edentulous sites are smooth and devoid of features. The stitching process may be faulty, especially in the palatal area. This article introduces a time-saving technique that easily captures tissues, prevents incorrect data processing, and uses common and inexpensive materials.
