بررسی میزان gap و overhang در ناحیه finish line کوپینگهای تهیه شده با سه روش ریختگی با دو نوع آلیاژ در ایمپلنتهای ITI
Background and Aim: An important criterion for success assessment of implant-supported prostheses is marginal fit. Vertical and horizontal discrepancy can result in loosening of the prosthetic screw, crestal bone resorption, peri-implantitis and loss of osseointegration. Despite careful attention to waxing, investing, and casting, marginal discrepancies are inevitable. The aim of this study was...
متن کاملDeffects in Dental Alloys Cast Single Tooth Restorations
Casting failures of alloys in dental technology should be the exception, not the rule. They have to be detected in time and associated with possible causes. For the experimental part base metal alloys single tooth restorations were achieved using the conventional lost wax process for casting in order to be evaluated. Some casting defects obtained during the experimental part are exemplified: in...
متن کاملمقایسه Marginal gap دو آلیاژ بیسمتال (مینالوکس و وراباند2) در مراحل پخت پرسلن
Statement of Problem: Nowadays economical issues on high gold alloys have changed the practice of metal-ceramic restorations toward base-metal alloys. Minalux is one of the base-metal alloys produced in Iran. Marginal fitness is of high importance to be evaluated in dental alloys.Purpose: The aim of the present study was to compare the marginal adaptation of two base-metal alloys, Minalux (Mava...
متن کاملEvaluation of Soldered Joints of Two Base Metal Ceramic Alloys: Supercast and Minalux
Background: Different soldering techniques have a variety of applications in dentistry. One of the most important uses of soldering is to join multiple-unit fixed partial dentures together. In this Study, two base metal alloys (Supercast and Minalux) were soldered and their tensile, compressive and flexural strengths were measured and compared to each other. Materials and methods: In this ...
متن کاملVacuum Brazing of Zirconium-Based Alloy and 321 Stainless Steel Using Titanium Based Filler Metal
Both Zirconium-based alloys and 321stainless steel are widely used as engineering alloys due to their good mechanical properties. Conventional fusion welding techniques for Zr alloys and stainless steel are not feasible due to the formation of brittle intermetallic compounds such as (Zr3Fe, ZrFe2 and Zr2Fe) and corrosion cracking. Brazing is one of the most wide...
