Retentive 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 کاملAn in vitro comparison of retentive force and deformation of acetal resin and cobalt-chromium clasps.
STATEMENT OF PROBLEM The use of metal clasps on anterior teeth may cause esthetic problems. Recently, acetal resins have been used as an alternative tooth-colored denture clasp material to improve esthetics. However, there are few studies to support acetal resin use. PURPOSE The purpose of this in vitro study was to compare the retentive force and deformation of acetal resin and cobalt-chromi...
متن کاملFlexibility of the Retentive Arm of Acetal Resin Clasp versus Cast Clasps- an in Vitro Study
Restoration of esthetics is an important factor to consider in the fabrication of a removable partial denture (RPD) . 1 Several types of polymers and metal alloys have been used in RPD construction. Frequently, RPD clasps made from the same alloy as the metal framework. The most common alloys used for clasps are cobalt-chromium (Co-Cr) alloy and gold and titanium alloys, although these may be u...

بر اساس نظریه افلاطون در باره شعر خلاقیت هنری مورد انتقاد قرار گرفته است. نظریه کلی در مورد شعر این بود که شعر از ظواهرتقلید میکند و نه حقیقت. چون سایه ای از حقیقت است. اما با پیدایش فلسفه نو افلاطونی، انتقاتات قبلی در مورد شعر و شاعری اصلاح شد. فلوطین در کتاب انئید، اساس خلق هنری را بر محور مُثل افلاطونی قرار داد. وی باور داشت که هنر مندان در خلق آثار هنری، تحت تاثیر مُثل افلاطونی بوده و عوالمی ...
