[Treatment of jaw cysts with a new kind of nanoparticular hydroxylapatite].

This article reports on the treatment of jaw cysts using a new bone substitute material. Ostim is a nanocrystalline, phase-pure hydroxylapatite which is manufactured in an aqueous suspension and then concentrated to form a white paste with a 35% content. The material is applied directly into the bone cavity using a syringe and, due to its paste consistency, produces uniform surface contact with the walls of the bone cavity. The material is fully resorbed and ensures rapid bony regeneration of jaw defects with no complications during the healing process. The results of 44 applications were described.
