An alternate pressure-free functional impression technique for implant-retained overdentures.

Overdenture treatment provides an esthetic and functional result that allows proper access for hygiene and maintenance. For implant-retained overdentures to be successful, functional loads must be distributed optimally to the mucosa and the abutments. For this purpose, impressions must record the soft tissue supporting areas simultaneously with accurate registration of the implant components. Usually, finger pressure is used to make functional impressions. This article describes an alternate pressure-free functional impression technique for implant-retained overdentures.
