An unconventional impression method using implant mount: an alternative to open-and closed-tray impression technique

Background:Various impression techniques have been proposed for making implant prostheses. Impressions are made at level –closed and open tray impressions, as well abutment impressions. Closed copings used to make the The limitations associated with copings, including expensive ones, pose a significant challenge in limited mouth-opening cases, customization of is not feasible.Aim: This study aimed compare dimensional accuracy four methods, open-tray, closed-tray, disposable mount coping splinted coping.Materials methods:An ideal maxillary edentulous acrylic model was windows created canine molar regions.
