In a clinical study in a microCT and histological evaluation of biopsy specimens from 17 patients participating in a clinical trial on sinus lift using Tigran’s non-resorbable Porous Titanium Granules (PTG), researchers have verified bone formation, mainly woven bone in close contact with the surface of the granules and bridging the intergranular space. No signs of inflammation in any of the biopsy specimens were observed. The authors point out that a prerequisite for sinus lift is primary implant stability and they underline that a significant resorption of a bone graft may occur over time, which may compromise the long-term implant stability. The authors conclude that the porous structure of PTG may favor osteoconduction and contribute to the stability that is necessary for long-term implant survival. The study has been published in the June issue of the International Journal of Oral & Maxillofacial Implants. Verket A, Lyngstadaas SP, Rasmusson L, Haanæs HR, Wallstrom M, Wall G, Wohlfahrt JC.

I am very pleased with the results in terms of bone growth but also with the authors comments on the all-important primary stability.” For further information, please contact: Arve Nilsson, acting CEO Tigran Technologies +46 768 60 77 10 a.nilsson@tigran.se www.tigran.se About Tigran Technologies Tigran Technologies AB (publ) is a dental development company based in Sweden.
