Fabrication of Closed Hollow Bulb Obturator Using Thermoplastic Resin Material
Purpose. Closed hollow bulb obturators are used for the rehabilitation of postmaxillectomy patients. However, the time consuming process, complexity of fabrication, water leakage, and discoloration are notable disadvantages of this technique. This paper describes a clinical report of fabricating closed hollow bulb obturator using a single flask and one time processing method for an acquired max...
متن کاملRetentive forces and fatigue resistance of thermoplastic resin clasps.
OBJECTIVES The objective of this study was to evaluate the retentive force of clasps made from three thermoplastic resins and cobalt-chromium (CoCr) alloy by the insertion/removal test simulating 10 years use. METHODS On standardized premolar metal crowns 112 clasps were fabricated, including 16 CoCr (1.0 mm thick) clasps and 32 clasps (1.0 or 1.5 mm thick) from each of the following thermopl...
متن کاملNanocomposite Coating Based on Thermoplastic Acrylic Resin and Montmorillonite Clay: Preparation and Corrosion Prevention Properties
Different amounts of nanoclay were incorporated into the acrylic resin matrix at 0, 1, 3, and 5 wt.% loadings. The coatings were applied on low carbon steel plates. Optical microscopy, sedimentation test, transmission electron microscopy, and X-ray diffraction were employed to investigate the dispersion of nanoclay in matrix. The corrosion resistance of coatings was evaluated by electrochemical...
متن کاملEvaluation of Thermoplastic Resin as a New Pattern Material for Posts: Dimensional Accuracy and Detail Reproduction
Traditionally, dark-cure (cold-cure) acrylic resin is used as pattern material for cast post and core. A new post system that incorporates a specially designed plastic support rod and a thermoplastic resin has been introduced to the market and is claimed to simplify the procedure for cast posts fabrication. The aim of the present work was to evaluate the dimensional accuracy and detail reproduc...
متن کاملColor stability, water sorption and cytotoxicity of thermoplastic acrylic resin for non metal clasp denture
PURPOSE The aim of this study was to compare the color stability, water sorption and cytotoxicity of thermoplastic acrylic resin for the non-metal clasp dentures to those of thermoplastic polyamide and conventional heat-polymerized denture base resins. MATERIALS AND METHODS Three types of denture base resin, which are conventional heat-polymerized acrylic resin (Paladent 20), thermoplastic po...
