Abstract:

امروزه انواع مختلفی از سیستم‌های روکش تمام پرسنلی در بین این انواع (Vita Zahnfabrik, Bad Sackingen Germany) In-Ceram از موقعیت ویژه‌ای برخوردار است. زیرا دارای زیبایی کافی و استحکام مناسبی می‌باشد.در این مطالعه، استحکام خمشی (Flexural Strength) ماده In-Ceram Core مورد ارزیابی قرار گرفته است. بدین منظور، ده نمونه میله ای شکل (Bar) با ابعاد 2.5× 6× 30 میلیمتر از ماده Core ساخته و توسط دستگاه اینسترون مدل 1195 به روش چهار نقطه‌ای، میزان استحکام خمشی اندازه‌گیری شده است.میانگین بدست آمده، استحکام خمشی 42 ±538 مگا پاسکال را نشان می‌دهد که این استحکام بیشتر از بقیه سرامیک‌های دندانپزشکی و قابل قبول برای استفاده کلینیکی است.

مقایسه استحکام خمشی پرسلن دندانی جدید (D4 Dentin)  با پرسلن دندانی کارخانه Vita (VMK 68N)

Statement of Problem: Dental porcelain is one of the best materials ever used in dentistry. Excellent tissue compatibility, esthetics, very low solubility in oral fluids, high compressive strength, and the lowest bacterial plaque accumulation on the glazed porcelain are some of its advantages. Porcelain brittleness due to its low tensile strength, impact strength and the occlusal attrition of o...

Fracture strength of three all-ceramic systems: Top-Ceram compared with IPS-Empress and In-Ceram.

PURPOSE The purpose of this study was to investigate the fracture loads and mode of failure of all-ceramic crowns fabricated using Top-Ceram and compare it with all-ceramic crowns fabricated from well-established systems: IPS-Empress II, In-Ceram. MATERIALS AND METHODS Thirty all-ceramic crowns were fabricated; 10 IPS-Empress II, 10 In-Ceram alumina and 10 Top-Ceram. Instron testing machine w...

بررسی اثر پالیش بر روی استحکام Flexural پرسلن فلدسپاتیک و مقایسه آن با اتوگلیز و اورگلیز

Statement of Problem: Ceramic restorations are popular because they can provide the most natural replacement for teeth. However, the brittleness of ceramics is a primary disadvantage. There are various methods for strengthening ceramics such as metal framework, ceramic cores, and surface strengthening mechanisms through glazing, work hardening and ion exchange. Purpose: The purpose of this stud...

تحلیل ریزساختار و سطح شکست و اندازه گیری استحکام خمشی فولاد متالورژی پودر کروم - مولیبدن

The fracture surfaces of PM Cr-Mo steels intensively depends on pores structure, densification, diffusion of alloying elements, contact area between particles (sinter necks), microstructural homogeneity, and type of applied load. Also, knowing about element distribution in PM parts to evaluate what places are good for crack growth, nucleation and coalescenc is important. In this investigatio...

بررسی تاثیر پدیده تبادل یونی (Ion exchange) بر روی استحکام خمشی پرسلن سرامکو II و پرسلن Colorlogic Venner

  The major foible of dental ceramics is their brittle nature. Therefore, the producers of these materials have focused on the “strength” issue. A method of increasing strength is ion exchange on porcelain surface which leads to formation of a compressive crust that opposing forces should overcome before developing a crack. In current study, ion exchange in two types of porcelain, Ceramco II wh...
