[Osteogenetic potential of gelatin and collagen in poorly regenerating bone layers (animal experiments)].

Normal tissue defects in the tibiae of 16 sheep were filled with gelatine, collagen or a mixture of both. Comparable rates of new bone formation occurred after observation periods of 6 and 12 weeks. The difference is not statistically significant. In our experiment collagen and gelatine showed neither a positive nor a negative influence on new bone formation.
