Simplified technique for refabrication of cast posts and cores.
This article describes a simple procedure of recording contours of an existing cast post and core that needs to be reconstructed, using a polyvinyl siloxane material as a matrix for fabrication of a new cast post and core in a relatively short time with reduced cost. The procedure involves the use of an acrylic resin material under pressure, which minimizes void formation in the post-and-core p...
متن کاملComparison of the efficiency and effectiveness of various techniques for removal of fiber posts.
A study was conducted to determine the efficiency and effectiveness of several techniques for fiber post removal. Four groups of 20 mandibular premolars were endodontically treated and obturated. Post spaces were prepared for the following post systems: ParaPost XH, ParaPost Fiber White, Luscent Anchors, and Aestheti-Plus. After cementation, 10 posts of each group were removed with their corres...
متن کاملComparison of the time required for removal of intraradicular cast posts using two Brazilian ultrasound devices.
The aim of this in vitro study was to compare the time required for removal of intraradicular cast posts cemented with zinc phosphate (ZF) or glass ionomer cement (GIC), using two Brazilian ultrasound devices (BUD). Seventy two human inferior premolars with single root canals were sectioned transversally at the cementoenamel junction. In each specimen, the root canal was endodontically treated,...
متن کاملRemoval resistance of glass-fiber and metallic cast posts with different lengths.
This study evaluated the strength required to remove glass-fiber and metallic cast posts with different lengths. Sixty endodontically treated canines were included and their roots were embedded in acrylic resin after discarding the crowns. Samples were randomly assigned to 3 groups according to the post length (n = 20): I- 6 mm, II - 8 mm and III- 10 mm. Each group was divided into 2 subgroups ...
متن کاملAccuracy of cast posts fabricated by the direct and the indirect techniques.
STATEMENT OF PROBLEM Patterns for custom cast posts and cores can be fabricated either by the direct or the indirect technique. Which technique is more accurate is unknown. PURPOSE The purpose of this in vitro study was to investigate the effect of pattern fabrication technique on the accuracy of post fit. MATERIAL AND METHODS Ten intact extracted premolar teeth with a single canal and simi...
