Placing the Implants in Immature Grafted Sites
One of the most common causes of prosthetically related implant failure is believed to be the too rapid loading of the implant supported prosthesis. When the implants are to be placed in grafted bone sites, the timing of the surgery is of utmost importance. Failure is ensured if the implant is loaded before the surrounding bone matures from woven bone into lamellar. Woven bone is only partly mineralized and is immature bone with an unorganized structure that is unable to withstand full scale stresses. The waiting period mandatory for implant survival in cases of grafted bone sites ranges from 6-9 months.
