Modified Cast Dowel Core for Treatment of Mutilated Crowns – Case
Dislodgement of crown is not uncommon in routine clinical practice. Inadequate support for the core is the most common reason for such failures. With the advent of fibre posts and resin cements, core build up has become more effective. But sin certain conditions with severe deep bite, supra-eruption and mutilation, cast metal dowel core offer greater advantage compared to non-metallic posts and...

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...
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...
