When a patient's tooth has undergone severe damage, replacing or stabilizing the tooth requires good quality bone structure in order for any support system or implant to take. Patients with poor bone volume are unlikely to see the same results as those without this issue. With Orthogen, LLC's trademark product, NanoGen, however, periodontal professionals can perform tooth repair and replacement even on patients with these bone volume problems, because NanoGen's unique nanotechnology has been shown to encourage bone formation.
