16. On dental ceramics and their fracture : a laboratory and numerical study
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
17. All-ceramic Fixed Partial Denture. Studies on aluminum oxide- and zirconium dioxide-based
Sammanfattning : Keramiska material har länge använts inom tandvården för framställning av tandersättningar. Keramer har många goda egenskaper som gör dem särskilt lämpliga att använda i munnen. LÄS MER
18. Soft tissue integration to dental implants
Sammanfattning : Soft tissue integration is a prerequisite for implant success. The role of the soft tissue barrier at implants is to provide an effective seal that protects the underlying bone and prevents access for microorganisms and their products. LÄS MER
19. Dental restorative materials from a work environmental perspective
Sammanfattning : The main occupational health hazard for dental personnel is muscle-skeletal problem, followed by symptoms caused by exposure to chemicals. Clinical dental work includes exposure to a number of products like soap, detergents, disinfectants, amalgam, mono- and oligomers, catalysts, inhibitors, solvents and adhesives. Some are chemically very active. LÄS MER
20. Managing Effects of Manufacturing Variation in Dental Medical Device Treatments - Increasing Geometrical Robustness
Sammanfattning : Today, there are many solutions for dental rehabilitation. A damaged tooth can be replaced with a dental crown, and a toothless patient can be rehabilitated with implants and a corresponding bridge set-up. Traditionally, a dental crown is manufactured by veneering porcelain to a metal surface that is obtained through the use of casting principles. LÄS MER
