Abstract:

Bone is among the most frequently transplanted tissues in the body. In Europe, about one million patients encounter a surgical bone reconstruction annually. The worldwide market of bone replacement materials is currently estimated at 5 billion Euros, with a 10% growth due to the ageing of the population. Natural grafts present several drawbacks which pushed scientists to investigate synthetic biomaterials. Although most synthetic bone substitutes available possess some of the positive properties of autografts, none yet have all the benefits of one's own bone. Among the available biomaterials,

Abstract:

Bone is among the most transplanted tissues for regeneration of bone defects, caused by trauma, age-related bone loss or bone infections. Due to their similar characteristics to the mineral phase of bone, calcium phosphates (CaPs) have raised a lot of interest. Some properties of CaPs, like biodegradability, biocompatibility, bioactivity and osteoconduction represent a great potential for this application. Among them, calcium phosphate cements (CPCs) have additional advantages like injectability and in situ hardening ability. Moreover, the possibility to tune the porosity of CaPs in general an

Abstract:

Calcium phosphates (CaPs) have been used extensively as bone replacement materials, substrates for drug release and transfection agents because of their non-cytotoxic nature and chemical similarity to the mineral component of human bone. However, biomolecule attachment to CaPs usually rely upon adsorption, which can lead to inconsistent coverage and variable release, and the fate of CaPs upon cellular internalisation is not fully understood. The difficulty in tracking the particles can be related to the visual similarity to granulation within the cells. This thesis sought to functionalise the

Bone defects resulting from disease or traumatic injury is a major health care problem worldwide. Tissue engineering offers an alternative approach to repair and regenerate bone through the use of a cell-scaffold construct. The scaffold should be biodegradable, biocompatible, porous with an open pore structure, and should be able to withstand the applied forces. Phosphate-based glasses (PGs) may be used as reinforcing agents in degradable composites since their degradation can be predicted and controlled through their chemistry.

Abstract:

One of the greatest obstacles to clinical translation of bone tissue engineering is the inability to effectively and efficiently vascularise scaffolds. This limits the size of defects that can be repaired, as blood perfusion is necessary to provide nutrient and waste exchange to tissue at the core of scaffolds. The goal of this work was to systematically explore whether architecture, at a scale of hundreds of microns, can be used to direct the growth of microvessels into the core of scaffolds. A pipeline was developed for the production of hydroxyapatite surfaces with controlled architecture.

Calcium phosphates (CaP) are widely used in various fields of biomedical applications as implant materials, mainly due to their chemical similarity to the inorganic component of bone. In many of the applications the dimensional accuracy is critical and implants need to be shaped, sized and machined as per requirement. But, being a ceramic material with strong atomic bonding, they have high hardness, brittleness and thus a limited ability to be machined and shaped to an accurate dimension required for many critical surgical applications. Hence, these ceramic based materials cannot compete with

博士<br>淡江大學<br>化學工程與材料工程學系博士班<br>100<br>To fulfill the properties of barrier membrane useful for guided bone tissue rgegenration in the treatment of periodontitis, a simple process containing oven-drying and lyophilization was proposed in this study to produce composite membrane from biodegradable chitosan (CS) and fnctional calcium phosphate. Calcium deficient hydroxyapatite (CDHA) having an average particle size of 45 nm was synthesized by reverse emulsion method. It was converted to the respective biphasic calcium phosphate (BCP, 226 nm) and ß-tricalcium phosphate (TCP, 450 nm) by calcinatio

碩士<br>國立臺灣大學<br>臨床牙醫學研究所<br>102<br>There are various kinds of commercial products claimed to be able to relieve the symptoms of dentin hypersensitivity, but none of the products have immediate and long-lasting effects. Our previous study showed that gelatin-templated calcium mesoporous silicate (GCMS) with 30% H3PO4 could efficiently occlude dentinal tubules by precipitation thus have great potential in treating dentin hypersensitivity. Also, GCMS with 30% H3PO4 could show great biocompatibility through dentin disc barrier. To be an idea dental material, it is important to find out the mechani

Tese de doutoramento em Engenharia de Tecidos, Medicina Regenerativa e Células Estaminais<br>Bone and cartilage defects derived from trauma or disease are major problems in orthopedics. Tissue engineering and regenerative medicine provides promising strategies for the regeneration of damaged tissues. Biomaterials, processed into porous scaffolds and hydrogels, have been playing a crucial role in the tissue regeneration. Controlling the physicochemical properties of biomaterials is important for inducing proper cellular response towards tissue formation, thus facilitating the regeneration

碩士<br>義守大學<br>材料科學與工程學系碩士班<br>93<br>A chemical reaction method was used to study the formation mechanisms of hydroxyapatite or calcium phosphate salts on the surface of different ceramic substrates, through controlling different concentrations of Ca2+、PO43- and OH- in the aqueous solution. In this study, sintered Ca3-(PO4)2, Al2O3 and ZrO2 ceramic composites were fabricated to be plate-like substrates for this particular chemical coating process. In the chemical coating or reacting process, different ceramic substrates were dipped in the 1 M H3PO4 aqueous solution at T=25~80℃ and pH=0.7~11,

Abstract:

Calcium phosphate cements are hydraulic cements.These are formed by a combination of one or more calcium orthophosphate powders. Calcium orthophosphates have been studied as bone re-pair materials for the last 80 years. CPC self-hardens to form hydroxyapatite, having excellent osteoconductivity and bone-replacement capability. The present study was aimed at preparation of alpha tricalcium phosphate and Si doped alpha tricalcium phosphate and studying the effect of addition of glass fibers into them. The physicochemical and mechanical properties of á-tricalcium phosphate (á-TCP) cement and Si d

Abstract:

The interaction at the surfaces of load bearing implant biomaterials with tissues and physiological fluids is an area of crucial importance to all kinds of medical technologies. To achieve the best clinical outcome and restore the function of the diseased tissue, several surface engineering strategies have been discussed by scientific community throughout the world. In the current work, we are focusing on one such technique based on laser surface engineering to achieve the appropriate surface morphology and surface chemistry. Here by using a pulsed and continuous wave laser direct melting tech
