Comparison of different ultrasonic vibration modes for post removal.
This in vitro study compared different ultrasonic vibration modes for intraradicular cast post removal. The crowns of 24 maxillary canines were removed, the roots were embedded in acrylic resin blocks, and the canals were treated endodontically. The post holes were prepared and root canal impressions were taken with self-cured resin acrylic. After casting, the posts were cemented with zinc phos...
متن کاملEffect of ultrasonic tip designs on intraradicular post removal
OBJECTIVES To evaluate the effect of different ultrasonic tip designs on intraradicular post removal. MATERIALS AND METHODS The crowns of forty human canine teeth were removed, and after biomechanical preparation and filling, the roots were embedded in acrylic resin blocks. The post spaces were made, and root canal molding was performed with self-cured acrylic resin. After casting (Cu-Al), th...
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 کاملEffect of the simulated periodontal ligament on cast post-and-core removal using an ultrasonic device
OBJECTIVE The aim of this study was to evaluate the effect of simulated periodontal ligament (SPDL) on custom cast dowel and core removal by ultrasonic vibration. MATERIAL AND METHODS Thirty-two human maxillary canines were included in resin cylinders with or without SPDL made from polyether impression material. In order to allow tensile testing, the roots included in resin cylinders with SPD...
متن کاملInfluence of Luting Agents on Time Required for Cast Post Removal by Ultrasound: an in Vitro Study
OBJECTIVE This in vitro study evaluated the influence of luting agents on ultrasonic vibration time for intraradicular cast post removal. MATERIAL AND METHODS After endodontic treatment, 30 roots of extracted human canines were embedded in resin cylinders. The post-holes were prepared at 10 mm depth and their impressions were taken using autopolymerizing acrylic resin. After casting procedure...
