Bioceramics dental applications

Surface properties (such as topography and wettability) of bioceramics similar to human bone can be obtained by decreasing the grain size of ceramic formulations into the nanometer regime. Such surface properties must be incorporated into proactive bioceramics for orthopedic and dental applications surface properties similar to those of physiological bone are needed in order to promote select cell interactions that lead to sufficient osseointegration between an orthopedic or...

HAp is one of the most important bioceramics for medical and dental applications because it is the main inorganic constituent of human hard tissue like bone and teeth. The chemical structure of HAp is presented in Fig. 3.

Knowledge of the surface structure of CaHAP panicles is fundamentally needed not only in medical and dental sciences but also in application of synthetic CaHAP particles to bioceramics and adsorbents for biomaterials, because the affinity of CaHAP surface to biomaterials is an important factor in all the cases. The surface structure of CaHAP was investigated by various means including infrared (IR) (38,39), NMR (40). TPD (41), and XPS (42). Among these methods, IR spectroscopy is most appropriate for the surface characterization of CaHAP particles. 

CBPCs may have an important role even in the production of artificial implants. Typically, one may exploit rapid-prototyping to produce exact shapes of the implants. From a practical standpoint, formation of a ceramic out of a paste would appear to be most suitable for rapid-prototyping processes [11]. Thus, coupling CBPC with rapidprototyping should lead to artificial body parts that not only match the namral bones in their composition, but in structure as well. The science of CBPCs paves the way for their use not only as dental cements and bioceramics for the 21st century, but as discussed in earlier chapters, many other applications as well. 

Abstract Aluminates form in binary systems with alkali, alkaline earth or rare-earth oxides and share the high melting point and resistance to chemical attack of the pure A1203 end-member. This means that these ceramics have a variety of applications as cements, castable ceramics, bioceramics, and electroceramics. Calcium aluminate cements are used for example in specialist applications as diverse as lining sewers and as dental restoratives.

Bioceramics. Ceramics used in biomedical applications. The chief applications are as dental ceramics (q.v.) and prostheses (q.v.). Alumina and synthetic apatite or hydroxyapatite are the most frequently used for prostheses, which must be compatible with body fluids. 

Bioceramic Applications The performance requirements of yttria-stabilized tetragonal zirconia polycrystal (TZP) to form biocompatible, strong components for use as hip, knee, and dental prostheses, and which demonstrate long-term resistance against aggressive body fluids and mechanical wear and tear, during a predicted lifetime of 15-20 years in the human body, include ...
