Fabrication of dental restorations made zirconia-based biomaterials with enhanced mechanical and tribological properties together customized surface topography microstructure for promoting enamel adhesion cell proliferation while hindering bacterial spreading is a very challenging task to accomplish through conventional machining operations. In fact, traditional milling processes sintered ceram...

The field of dentistry is constantly changing with the introduction new materials and techniques that resulted in good treatment outcome.Bio-ceramics are amongst recently introduced which have changed face dentistry. Bioceramics biocompatible, nontoxic, non-shrinking usually chemically stable within biological environment.The development bioceramic based has greatly improved dentist’s possibili...

We report elastic constant calculation and a "theoretical" tensile experiment on stoichiometric hydroxyapatite (HAP) crystal using an ab initio technique. These results compare favorably with a variety of measured data. Theoretical tensile experiments are performed on the orthorhombic cell of HAP for both uniaxial and biaxial loading. The results show considerable anisotropy in the stress-strai...

Bioceramics, because of its excellent biocompatible and mechanical properties, has always been considered as the most promising materials for hard tissue repair. It is well know that an appropriate cellular response to bioceramics surfaces is essential for tissue regeneration and integration. As the in vivo implants, the implanted bioceramics are immediately coated with proteins from blood and ...

PURPOSE We describe in our study a modified standard enucleation, using sclera harvested from the enucleated eye to cover the prosthesis in order to insert a large porous implant and to reduce postoperative complication rates in a phthisis globe. METHODS We perform initially a standard enucleation. The porous implant (Bioceramic) is then covered only partially by the patient's sclera. The imp...

Calcium phosphate ceramic scaffolds have been widely investigated for bone tissue engineering due to their excellent biocompatibility and biodegradation. Unfortunately, they have the shortcoming of low mechanical properties. In order to provide strong, bioactive, and biodegradable scaffolds, a new approach of infiltrating the macro-tube ABS (acrylontrile butadiene styrene) templates with a hydr...

Hydroxyapatite (HA), as a bone mineral component, has been an attractive bioceramic for the reconstruction of hard tissues. However, its poor mechanical properties, including low fracture toughness and tensile strength, have been a significant challenge to the application of HA for the replacement of load-bearing and/or large bone defects. Among materials studied to reinforce HA, carbon nanotub...

In vitro activity is important when considering the choice of a multiphasic bioceramic scaffold as phases can dissolve or transform at different rates. The aim this study focused on synthesis and in analysis ceramics obtained from melt by directional solidification. Depending growth rate new composition bioactive coexist same sample: akermanite, monticellite, tricalcium phosphate Nurse's A phas...
