Bioactive ceramic-reinforced composites for bone augmentation.
Summary of "Bioactive ceramic-reinforced composites for bone augmentation."
Biomaterials have been used to repair the human body for millennia, but it is only since the 1970s that man-made composites have been used. Hydroxyapatite (HA)-reinforced polyethylene (PE) is the first of the 'second-generation' biomaterials that have been developed to be bioactive rather than bioinert. The mechanical properties have been characterized using quasi-static, fatigue, creep and fracture toughness testing, and these studies have allowed optimization of the production method. The in vitro and in vivo biological properties have been investigated with a range of filler content and have shown that the presence of sufficient bioactive filler leads to a bioactive composite. Finally, the material has been applied clinically, initially in the orbital floor and later in the middle ear. From this initial combination of HA in PE other bioactive ceramic polymer composites have been developed.

SUMMARY This study evaluated the influence of ceramic thickness and ceramic materials on fracture resistance of posterior partial coverage ceramic restorations. Forty extracted molars were allocated i...
This study was conducted to develop novel ceramic bone substitute that resembles the autologous bone behaviour when used as graft material. Solid-state reaction at 1100 ºC was performed to synthesize...
To successfully rehabilitate edentulous patients using endosseous implants, there must be enough available bone. Several techniques have been proposed for augmentation of sites with insufficient bone ...
Straumann Bone Ceramic (SBC) and BioOss will be used as bone grafting materials when there is a need for bone augmentation in the posterior upper jaw. 9 months later the bone formation is ...
The objective of the study is to test the efficacy on bone formation of Straumann Bone Ceramic as a grafting material applied in buccal bone dehiscences on simultaneously placed oral impla...
This study is designed to perform a head-to-head comparison of two synthetic ceramic bone graft substitutes, bioactive glass (BAG) and beeta-tricalcium phosphate (TCP), in filling of conta...
The purpose of this study is to compare a new biomaterial with an already existing treatment principle (Bio-Oss/Bio-Gide) with regard to their ability to preserve the dimensions of the alv...
Comparison of the functional result and speed of rehabilitation between two types of hip prostheses: primary ceramic-on-ceramic total hip replacement versus metal-on-metal hip resurfacing.
Medical and Biotech [MESH] Definitions
Preprosthetic surgery involving rib, cartilage, or iliac crest bone grafts, usually autologous, or synthetic implants for rebuilding the alveolar ridge.
The eight bones of the wrist: SCAPHOID BONE; LUNATE BONE; TRIQUETRUM BONE; PISIFORM BONE; TRAPEZIUM BONE; TRAPEZOID BONE; CAPITATE BONE; and HAMATE BONE.
A type of porcelain used in dental restorations, either jacket crowns or inlays, artificial teeth, or metal-ceramic crowns. It is essentially a mixture of particles of feldspar and quartz, the feldspar melting first and providing a glass matrix for the quartz. Dental porcelain is produced by mixing ceramic powder (a mixture of quartz, kaolin, pigments, opacifiers, a suitable flux, and other substances) with distilled water. (From Jablonski's Dictionary of Dentistry, 1992)
Agents that inhibit BONE RESORPTION and/or favor BONE MINERALIZATION and BONE REGENERATION. They are used to heal BONE FRACTURES and to treat METABOLIC BONE DISEASES.
