PURPOSE To evaluate the dimensional accuracy of several impression methods including agar alginate combined impression in vivo; the marginal accuracy of stone dies was determined using a new electroformed master crown technique. MATERIALS AND METHODS Cast cores with knife-edge and chamfer margins and electroformed master crowns were fabricated for 3 patients. Five impressions were taken of ea...

Statement of the Problem: Understanding about impression materials, their properties, uses and manipulation can guide operators towards having more successful restorations. Purpose: The aim of this in vitro study was to compare the accuracy of a condensation silicone impression material, Optosil, and an addition poly siloxane impression material, Elite-HD. Materials and Method: A laboratory mod...

Impression management, the process by which people control the impressions others form of them, plays an important role in interpersonal behavior. This article presents a 2-component model within which the literature regarding impression management is reviewed. This model conceptualizes impression management as being composed of 2 discrete processes. The 1st involves impression motivation—the d...

A major aim of Kansei engineering is to translate human impressions into physical features of certain objects. When seeing a certain object, different individuals would try to express their impression of it with many different words even if they feel the same emotion for the object. However, no efficient approach to deal with such a large variety of impression words has been proposed so far. Th...

This research explores the use of impression management tactics in combination. Two studies were conducted to identify three profiles of impression management use and to examine how three individual difference variables are related to these patterns. The results suggest that women are less aggressive than men in using impression management, that high self-monitors favor positive impression mana...

Though the necessity to place the finish line into the gingival sulcus obviously has a negative effect on the quality of the impression,4,8-10 aspects of gingival retraction have only been sparsely investigated.3-5 The aim of gingival retraction is to allow access for the impression material beyond the abutment margins and to create space for the impression material to be sufficiently thick. Te...

PURPOSE The aim of this study was to evaluate the effect of dimensional stability of splinting material on the accuracy of master casts. MATERIALS AND METHODS A stainless steel metal model with 6 implants embedded was used as a master model. Implant level impressions were made after square impression copings were splinted using 5 different techniques as follows. (1) Splinted with autopolymeri...

BACKGROUND Different factors such as impression techniques and materials can affect the passive fit between the superstructure and implant. The aim of this study was to determine the effect of different impression materials and techniques on the dimensional accuracy of implant definitive casts. MATERIALS AND METHODS Four internal hex implants (Biohorizons Ø4 mm) were placed on a metal maxilla...
