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...

objective: the aim of this study was to evaluate the dimensional stability of casts made from an alginate impression material poured immediately and stored after specific periods. materials and methods: the common alginate used in iran (super; iralgin, golchai co., tehran, iran) was tested. a master model was mounted on a special device and used to obtain the impressions. these impressions were...

This paper gives a personal impression of the conference “Asymmetrical PNe II: From Origins to Microstructures”, flags some of the highlights, gathers together some facts and terminology, and indicates some promising future lines of work in this field.

Basilar impression is a skeletal malformation characterized by translocation of the upper cervical spine and clivus into the foramen magnum, giving rise to various symptoms related to brainstem, upper spinal cord, and cerebellar compression. It is generally classified as primary (familial), in which the defect is unaccompanied by intrinsic abnormalities of bone, or as secondary, reflecting an i...

abstract introduction: impression making is one of the most important steps in fixed prosthodontics. due to contra-dictory opinions on the issue of the accuracy of silicone impression material as a function of technique, this study was carried out to assess the dimensional accuracy of master casts made by rapid silicone material as a function of three impression techniques: with 2mm space, with...
