The nasal sinuses exist within the upper jaw bone, close to the roots of the back teeth. In many cases, pain within the sinuses can be mistaken as tooth pain because of their proximity.
When back teeth are lost, the jaw bone shrinks. If the sinuses expand into the area where the roots of the teeth once existed, a sinus elevation with graft may be needed prior to implant placement.
To elevate the sinus and rebuild lost bone, grafting material is inserted under the sinus membrane and through the jaw bone. When bone loss is extensive, a healing period may be required prior to implant placement.
Implants can be placed once the graft consolidates within the jaw bone. After healing, crowns can be fabricated over the implants to replace the missing teeth.
