In a pilot study of two patients with bilateral sinus augmentation, deproteinized bovine particulates (Bio-Oss®) were placed as bone substitute material on one side and Tigran’s nonresorbable Porous Titanium Granules (PTG) on the other side. After 9 months, biopsies were performed for histologic and 3-dimensional analysis. Both types of bone substitutes were integrated into the bone. Multinuclear cells (responsible for bone resorption) were observed in the Bio-Oss biopsies, but not in the PTG biopsies. The study has been published in the August issue of the journal Implant Dentistry. Vandeweghe S, Leconte C, Ono D, Coelho PG, Jimbo R. Comparison of Histological and Three-Dimensional Characteristics of Porous Titanium Granules and Deproteinized Bovine Particulate Grafts Used for Sinus Floor Augmentation in Humans: A Pilot Study.

Arve Nilsson, acting CEO and director of Tigran Technologies, said: I am very pleased with the result, but also with that the authors emphasize the importance of biocompatibility and porosity of bone substitute materials.
