  1. 1. Resin composites Sandwich restorations and curing techniques

    University dissertation from Umeå : Odontologi

    Author : Anders Lindberg; Umeå universitet.; [2005]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; Adaption; Clinical; Degree of conversion; Depth of cure; Flowable; Resin composite; Restorations; SEM; Medicin;

    Abstract : Since the mid-1990s resin composite has been used for Class II restorations in stress-bearing areas as an alternative to amalgam. Reasons for this were the patients’ fear of mercury in dental amalgam and a growing demand for aesthetic restorations. READ MORE

  2. 2. Resin transfer moulded composite materials : processing, structure, property relationships

    University dissertation from Luleå : Luleå tekniska universitet

    Author : J. Anders Holmberg; [1997]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymeric Composite Materials; Polymera konstruktionsmaterial;

    Abstract : This thesis contains analysis of the performance of polymer composites manufactured by resin transfer moulding (RTM). The thesis consists of six papers, where the first two deals with the tensile strength of composites reinforced with randomly oriented glass fibres, which still is the most common reinforcement in RTM manufacturing.

  3. 3. Conventional, microfilled and hybrid composite resins laboratory and clinical evaluations

    University dissertation from Umeå : Umeå universitet

    Author : Jan W. V. van Dijken; Umeå universitet.; [1987]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; composite resin; caries; gingivitis;

    Abstract : Three types of composite resins, classified as conventional, microfilled and hybrid resins were compared with respect to surface characteristics, effect on the gingival margin, marginal adaptation and clinical durability in anterior cavities.The surface characteristics were studied in in vitro systems by means of scanning electron microscopy.

  4. 4. Process Modeling of Composite Manufacturing

    University dissertation from Umeå : Umeå universitet

    Author : Mohammad Sadegh Rouhi; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Finite element Analysis FEA ; Poro-Mechanics; Polymer Composites.; Manufacturing Technologies;

    Abstract : The focus of this research thesis is toward developing a framework for holistic modeling of composites manufacturing of fiber reinforced structural composites. The processes that have been considered are Liquid Composite Molding (LCM) and Out Of Autoclave (OOA) processes, ranging from Liquid Resin Infusion (LRI) and Resin Transfer Molding (RTM) in LCM processes, to Vacuum Bag Only (VBO) and Evac prepregs in OOA processes.

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

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Nazanin Emami; Luleå tekniska universitet.; [2004]
    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.
