16. On the tissue response to hafnium, titanium and thin calcium phosphate coatings
Abstract : Background: Titanium (Ti) is the gold standard material for load-bearing implants. Although high success rates have been reported for Ti implants, failures do occur. Alternative materials/surface modifications might further improve the performances of Ti implants, particularly in situations with non-optimal local tissue conditions. READ MORE

17. On the influence of micro-and macroscopic surface modifications on bone integration of titanium implants
Abstract : Background: Osseointegrated titanium implants are routinely used in clinical denstistry as anchorage units for dental prostheses. Although the overall clinical results are good, there are clinical situations when an optimized implant healing is desirable, for instance in order to shorten healing periods and to allow immediate loading.

19. Porcelain veneering of titanium : clinical and technical aspects
Abstract : Guld- och andra legeringar har i många år använts som material vid framställning av kronor och broar för ersättning av skadade eller förlorade tänder. Emellertid har tvivel uppstått kring lämpligheten av att använda guldlegeringar i tandersättningar, då guld har visat sig kunna ge biverkningar i form av allergiska reaktioner. READ MORE

20. Micro-grinding of titanium
Abstract : Titanium and its alloys are difficult-to-cut materials, commonly used in several application fields, such as: medicine, aerospace, automotive and turbine manufacturing due to their biocompatibility, corrosion resistance, excellent mechanical and thermal properties, and light weight. However, its machining is associated with several difficulties, such as high tool wear, low surface quality, high cutting forces and high costs. READ MORE
