Surface treatments of the biomaterials are of great interest in many biomedical applications. Hydroxyapatite is a favorable candidate for surface modification of the implants. To date, a wide variety of methods have been developed to produce bio-active/biocompatible coatings with desirable features in order to improve the performance of the implants. This paper strives to overview the present p...

The fracture rate of third-generation ceramic liners is greatly reduced compared with first- and second-generation liners because of improvements in the design and manufacturing process. Fractures of the alumina-bearing couple are rare for the same reason.This article describes a case of a fracture of an alumina-bearing couple delta ceramic liner without trauma history that was treated with cer...

Cast metal post-core systems have a long history of successful use because of their superior physical properties. However, their high elastic modulus can cause stress concentrations within the surrounding radicular dentin, resulting in root fractures. Moreover, the increasing demand for more esthetically appealing and biocompatible restorations has led to the development of tooth-colored, trans...

A new integration concept for micro-nano-integration based on a new bonding technique between nano-scaled, modified Black Silicon (BSi) and an adapted, unfired LTCC substrate is presented. The novel technique enables to combine advantages of silicon and ceramic technology, especially electrical and fluidic interconnects from nmto mm-scale. Current bonding concepts of silicon on ceramics need jo...

objectives : the purpose of this in vitro study was to compare the marginal adaptation and fracture resistance of a zirconia-based all-ceramic restoration with two preparation designs. materials and methods: twenty-four mandibular premolars were randomly divided into two groups (n=12); the conventional group received a peripheral shoulder preparation and the modified group received a buccal sho...

different techniques have been introduced for the removal of ceramic brackets. since the early 1990s, lasers have been used experimentally for debonding ceramic brackets. the goal of this study is to give a comprehensive literature review on laser-aided ceramic bracket debonding. pubmed and google scholar databases were used to identify dental articles with the following combination of key word...
