  1. 1. Zirconium dioxide based dental restorations : studies on clinical survival and fracture behaviour

    Detta är en avhandling från Departments of Prosthetic Dentistry and Materials Science and Technology, Faculty of Odontology, Malmö University

    Författare :Christel Larsson; Malmö University.; [2011]
    Nyckelord :ODONTOLOGY; ODONTOLOGI; Medicine; Zirconium dioxide; Y-TZP; Dental restorations;

    Sammanfattning : ABSTRACT The loss of teeth can affect a person’s appearance and functions such as eating and speaking. There is thus a need for prosthetic re-habilitation to improve quality of life. For many patients, a fixed dental restoration is preferred, and a common restoration is a por-celain-fused-to-metal bridge retained by teeth or implants. LÄS MER

  2. 2. Resin composites Sandwich restorations and curing techniques

    Detta är en avhandling från Umeå : Odontologi

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

    Sammanfattning : 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. LÄS MER

  3. 3. Calcium aluminate cement as dental restorative Mechanical properties and clinical durability

    Detta är en avhandling från Umeå : Umeå universitet. Institutionen för odontologi

    Författare :Karin Sunnegårdh-Grönberg; Umeå universitet.; [2004]
    Nyckelord :mechanical properties; clinical; restorations; ceramic; cement; resin composite; adaptation; SEM; odontologi; Odontology;

    Sammanfattning : In 1995, the Swedish government recommended the discontinuation of amalgam as restorative in paediatric dentistry. Because the mercury content in amalgam constitutes an environmental hazard, its use has declined. LÄS MER

  4. 4. Clinical aspects of restorative treatment in the primary dentition

    Detta är en avhandling från Umeå : Umeå universitet. Institutionen för odontologi

    Författare :Mirja Varpio; Göteborgs universitet.; Gothenburg University.; [1993]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Child; Child; Preschool; Cohort Studies; Composite Resins; chemistry; DMF Index; Dental Caries; epidemiology; microbiology; pathology; therapy; Dental Cavity Preparation; classification; Dental Enamel; pathology; Dental Restoration; Permanent; statistics numerical data; Follow-Up Studies; Glass Ionomer Cements; chemistry; Humans; Molar; Prevalence; Prosthesis Failure; Recurrence; Sweden; epidemiology; Tooth; Deciduous;

    Sammanfattning : The failure rate of restorative treatment in primary teeth was studied in a cohort of children born in 1981 and related to caries diagnosis, prevalence and distribution on different tooth surfaces, and compared with a cohort of children born in 1971. Concurrently, the longevity of composite resin in modified Class 2 cavities in primary molars was followed up and the resistance of deciduous and permanent enamel to acid adjacent to composite resin and glass polyalkeonate cement (GPA) was tested in vitro.

  5. 5. On dental ceramics and their fracture a laboratory and numerical study

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Wen Kou; Umeå universitet.; [2010]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Dental ceramics; Finite element analysis; Fixed partial denture; Fracture; Numerical modeling; Surface treatment; ODONTOLOGY Biomaterials; ODONTOLOGI Biomaterial; odontologi; Odontology;

    Sammanfattning : Background Surface treatments and irregularities in the surfaces may affect the fracture of ceramics. The effects of various treatments on the surface texture of different types of ceramic cores/substructures was therefore qualitatively, quantitatively and numerically evaluated. LÄS MER
