Bone Imolant for lost bony support What can be done to preserve existing bone and add lost bone ? Preservation
5-10% of bone is lost in the first year after an extraction and a further 2% a year thereafter. It is beneficial to implant bone at the time of tooth loss, to reduce bony loss and preserve as much ridge as possible.
This is done by packing bone particles into the socket at the time of extraction. A collagen membrane may be used to protect the implant. Several types of bone are available, including uman bone, artificial bone and, best of all, the patient's own bone. Bone Implants If not enough bone exists to permit a dental implant (or to seat a denture) then ridge augmentation can replace missing bone. This may be as blocks of bone or bone particles. New bone may be held in place by titanium screws or using membranes.
Sinus Lift When vertical bone is lost to an expanding nasal sinus. new bone may be added by simultaneously pushing the sinus membrane up and placing bone particles in its place. Small amounts may be achieved. enough for single implants through the implant drill hole : closed sinus lift; For larger amounts and multiple implants, a more extensive surgery: open sinus lift surgery is necessary.
