Sinus Bone Regeneration
The maxillary sinuses are behind and above your cheek bone and on top of the upper back teeth. These sinuses are empty cavities with the roots of the natural upper teeth extend up into the cavity. As we age, our sinus cavities get bigger. When these upper back teeth are removed, there is bone loss and much less bone separating the maxillary sinus and the mouth. Dental implants need this bone to predictably hold them in place long term. The bone in this area of the mouth is routinely very soft (like Styrofoam) so having plenty of bone and a number of implants is essential for long term success
So the upper back part of the mouth is a unique situation where the bone is lost both from the sinus cavities getting bigger and from the bone lost from periodontal disease, trauma, infection and or denture wear. REMEMBER wearing a denture or a partial ACCELLERATES the bone loss in an area where a tooth is missing. When the resulting sinus floor is very thin, it is impossible to predictably place dental implants in this bone and either sinus bone regeneration or other methods may be needed to replace the lost chewing teeth (see Teeth in a Day).
These sinus bone regeneration procedures must be performed on a healthy sinus and Dr Kammeyer will often work with ENT physicians to help attain a stable sinus health before proceeding with this procedure. Dr Kammeyer has been regenerating bone in the sinus cavity since 1995 and has had extensive training at Loma Linda University where these procedures were developed.
