Simplified method for determining fracture toughness of two dental ceramics.
This study compared the fracture toughness values (KIC), which were derived from simplified techniques: the indentation fracture (IF), the indentation strength (IS), and fractographic approach to that from a standard testing using surface cracks in flexure (SCF). Forty bar specimens, twenty IPS Empress(®) Esthetic and twenty IPS e.max(®)Ceram were prepared. Ten specimens in each material were t...
متن کاملFatigue of dental ceramics.
OBJECTIVES Clinical data on survival rates reveal that all-ceramic dental prostheses are susceptible to fracture from repetitive occlusal loading. The objective of this review is to examine the underlying mechanisms of fatigue in current and future dental ceramics. DATA/SOURCES The nature of various fatigue modes is elucidated using fracture test data on ceramic layer specimens from the denta...
متن کاملCeramics for Dental Applications: A Review
Over the past forty years, the technological evolution of ceramics for dental applications has been remarkable, as new materials and processing techniques are steadily being introduced. The improvement in both strength and toughness has made it possible to expand the range of indications to long-span fixed partial prostheses, implant abutments and implants. The present review provides a state o...
متن کاملNovel glass-ceramics for dental restorations.
BACKGROUND There are many different ceramic systems available on the market for dental restorations. Glass-ceramics are a popular choice due to their excellent esthetics and ability to bond to tooth structure allowing a more conservative approach. However, at present, these materials have insufficient strength to be used reliably in posterior regions of the mouth. PURPOSE The aim of this revi...
متن کاملOntoceramic: an OWL ontology for ceramics classification
In this note, we describe Ontoceramic, an OWL 2 ontology for cataloguing and classifying ancient ceramics. Ontoceramic has been defined through a synergic effort of computer scientists and archaeologists, by taking into account the most important papers in the field. It has been designed with the purpose of efficiently addressing significant problems concerning knowledge management about cerami...
