Objectives: To study the stress distributions in maxillary central incisor restored with Ni-Cr custom-made, gold custom-made, prefabricated titanium and prefabricated glass fibre dental posts subjected to oblique occlusal load at 100 N. Materials and Methods: Four three dimensional finite element models of a maxillary central incisor restored with Ni-Cr (Model I), gold custom-made (Model II), prefabricated titanium (Model III) and prefabricated glass fibre (Model IV) dental posts were constructed and oblique loading of 100 N was applied. Stress analysing at the along the centre of the post and post-surrounding structure interfaces were computed. Results: The result of this study indicates …
Alumina Ceramic For Dental Applications: A Review Article., Ahmed A. Madfa
Alumina Ceramic For Dental Applications: A Review Article., Ahmed A. Madfa
Ahmed A. Madfa
Alumina has received considerable attention and has been historically wellaccepted as biomaterials for dental and medical applications. This article reviews the applications of this material in dentistry. It presents a brief history, dental applications and methods for improving the mechanical properties of aluminabased materials. It also offers perspectives on recent research aimed at the further development of alumina for clinical uses, at their evaluation and selection, and very importantly, their clinical performance. This article also stated about the Functionally Graded Materials (FGMs) which has been conceived as a new material design approach to improve performance compared to traditional homogeneous and …

The emergence of Mineral Trioxide Aggregate (MTA) as endodontic repair filling material has generated a lot of interest due to its superior sealing ability and biocompatibility. Although MTA possesses superior sealing ability to traditional endodontic repair filling materials, such as calcium hydroxide, but it has poor handling characteristics. A novel endodontic repair filling materials with similar chemical composition, but improved handling characteristics, was recently developed. Recently, BioAggregate repair filling materials is claimed as biocompatible material and promotes cementogenesis and forms a hermetic seal inside the root canal. More recently, Biodentine and EndoSequence endodontic repair materials introduced to the market. Both …

Due to an increasing interest in esthetics and concerns about toxic and allergic reactions to certain alloys, zirconia was proposed as a new ceramic material in the later part of 20th century. It has become a popular alternative to alumina as biomaterial and is being used in dental applications for fabricating endodontic posts, crown and bridge restorations and implant abutments. It has also been applied for the fabrication of esthetic orthodontic brackets. This article presents a brief history, dental applications and new methods for fabrication of zirconia improving its mechanical properties. Additionally, the bonding between zirconia and resin cements as …
