متن کاملAltering internal surface of putty impression material for better recording of tooth preparation margins
This article describes the clinical procedures for a modified putty-wash impression technique. In this method, the hydraulic pressure induced from planned flowing the wash material from the inner surface of putty impression toward the vestibules pull over the gingival tissues covering the finishing line. This simple method reduces the need to using retraction cord in normal depth finishing line...
متن کاملSurface reproducibility of resin die materials with various impression materials.
Surface reproduction was evaluated for epoxy resin and polyether resin dies as well as for gypsum dies by observing the changes in roughness. Significant differences were found by the interaction of the impression and the dies. The resin dies generally showed better results than the gypsum dies when the elastomeric impressions were used. Especially the resin dies were both excellent in surface ...
