Castability of a commercial castable glass ceramics.
This study was carried out to determine the design and thickness of the cervical margin of a castable ceramic restoration from the point of view of its castability. Castability of castable ceramics was lower compared to Ag-Pd-Au and Co-Cr alloy with the use of the mesh pattern and rod pattern test (p < 0.05). It was more dependent on the pattern thickness than alloys (p < 0.05), and perfect rep...
متن کاملEffect of base metal alloys recasting on marginal integrity of castable crowns.
INTRODUCTION Base metals have a wide use in casting methods. Sometimes they are reused in laboratories which may have an adverse effect on the restoration marginal integrity. This study aimed to investigate the effect of recasting of alloys on marginal integrity of restorations. MATERIALS AND METHODS Models with two types of finishing lines shoulder bevel 45° and shoulder 135° were produced a...
متن کاملZirconia Bioceramics as All-ceramics Crowns Material: a Review
Zirconia (ZrO 2 ), known as a kind of bioceramics widely applied in prosthodontics, is considered as a promising alternative to conventional bioceramics owing to its desirable mechanical strength, toughness, wear resistance, corrosion resistance, biocompatibility etc. However, the development of zirconia is hindered due to its instability in long-term clinical observations such as the cracking ...
متن کاملMoldable and Castable Polygons
This paper introduces the concepts of Moldability and Castability of simple polygons and relates Moldability to Monotonicity. We detail a (n) algorithm for determining all n forward maximal monotone chains of a simple polygon and apply this algorithm to the problems of determining 2-Moldability, 2-Castability and the minimum monotone decomposition of a simple polygon 9]. Our results include a s...
متن کاملCombined Prosthesis with Extracoronal Castable Precision Attachments
Satisfactory restoration in a patient with a partially edentulous situation can be challenging especially when unilateral or bilateral posterior segment of teeth is missing. Successful restoration can be done with various conventional and contemporary treatment options. One such treatment modality is attachment-retained cast partial dentures. This paper describes a case report of a patient with...
