2. 1. On dental ceramics and their fracture : a laboratory and numerical study

   Author : Wen Kou; Göran Sjögren; Tore Dérand; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Dental ceramics; Finite element analysis; Fixed partial denture; Fracture; Numerical modeling; Surface treatment; Biomaterials; Biomaterial; odontologi; Odontology;

   Abstract : 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. READ MORE

4. 2. Interface Defeat and Penetration: Two Modes of Interaction between Metallic Projectiles and Ceramic Targets

   Author : Patrik Lundberg; Bengt Lundberg; Charles E. Anderson Jr.; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering physics; projectile; target; impact; interface defeat; penetration; tungsten; ceramic; replica scaling; Teknisk fysik; Engineering physics; Teknisk fysik;

   Abstract : Ceramics constitute an important group of low-density armour materials. Their high intrinsic strength makes it possible to design ceramic armour systems capable of defeating projectiles directly on the ceramic surface. READ MORE

5. 3. Deformation and Fracture of Ceramics and Ceramic Composites

   Author : Thomas Hansson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : An understanding of the deformation and fracture behaviour of ceramic materials is of considerable importance in the development of ceramics as reliable structural materials. Of particular interest is how such behaviour is influenced by the microstructure, for example in multiphase materials such as composites. READ MORE

6. 4. On core and bi-layered all-ceramic fixed dental prostheses, design and mechanical properties : studies on stabilized zirconiumdioxide

   Author : Deyar Mahmood Jallal Hadi; Malmö högskola; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Y-TZP; Zirconia; All-ceramic FDPs; connector design; radius; state-of-the-art; CAD CAM; multi-layer technique; veneering ceramic; split-file; over-pressing; dental porcelain; MECHANICAL PROPERTIES;

   Abstract : Loss of teeth can affect a person’s self-esteem, social life, appearance and oral function. Reconstruction of a missing tooth has scientifically been shown to increase self-esteem and quality of life and to maintain oral function. For many patients a fixed dental prostheses (FDP) is preferred, either tooth- or implant-supported. READ MORE
