  2. 16. Variables affecting stress development and resin conversion in light-cured dental composites

    Author : Nazanin Emami; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Elements; Maskinelement; Polymeric Composite Materials; Polymera konstruktionsmaterial;

    Abstract : The general aim of this dissertation was to identify and investigate factors that can be used to minimize stress development in light cured dental resins without compromising the conversion level of the polymer. Modulus of elasticity, polymerization contraction strain, degree of conversion and shrinkage of light-cure dental composites were determined after curing with three different light power densities where total irradiated energy (J/cm2) kept constant.

  5. 18. On platelet-rich plasma in reconstructive dental implant surgery

    Author : Andreas Thor; Göteborgs universitet; []
    Keywords : autogenous bone graft; bone formation; coagulation; clinical study; complement; dental implant; experimental study; growth factors; platelet activation; platelet-rich plasma; sinus lift surgery; thrombogenicity;

    Abstract : Abstract Background Severe athrophy of the edentulous maxilla may require augmentation before implants can be placed. Autogenous bone has been used for reconstruction in block or in particulated form. READ MORE

  6. 19. Micromechanical retention and chemical bonding to polycrystalline dental ceramics : studies on aluminum oxide and stabilized zirconium dioxide

    Author : Evaggelia Papia; Malmö högskola; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; alumina; aluminium oxide; bond strength; oxide ceramics; polycrystalline dental ceramics; stabilized zirconium dioxide; Y-TZP; zirconia; adhesive cements;

    Abstract : Det pågår en ständig utveckling av olika dentala material avsedda föratt ersätta förlorad tandsubstans. En materialgrupp som är särskiltintressant är höghållfasta keramiska material, oxidkeramer så somyttriumdioxidstabiliserad tetragonal polykristallin zirkoniumdioxid(Y-TZP). READ MORE

  7. 20. Submicron Calcium Phosphate Spheres for Biomedical Applications : Synthesis and Use

    Author : Tao Qin; Håkan Engqvist; Fredrik Nikolajeff; Jie Huang; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; calcium phosphate; spheres; dentinal hypersensitivity; drug release; tooth bleaching;

    Abstract : Calcium phosphate spheres as biomaterials have been attracting attention in recent years. Calcium phosphate occurs naturally in bone, and a hollow structure could be advantageous for drug loading and release. READ MORE
