Publicerade studier
Denzir startade som ett forskningsprojekt på Tandläkarhögskolan i Umeå 1987. Målet var att utveckla biokompatibla material för dentala applikationer. Ända sedan dess har vi varit aktiva genom att bedriva egna studier och stödja oberoende forskning inom material området zirconia. Här har vi samlat en del studier som alla berör våra material och produkter.
