All Teeth Missing

Sometimes all the teeth are missing in the upper jaw and there is insufficient bone to support dental implants. This problem can often be corrected surgically with the use of Sinus Elevation (Lift) procedures  to replace the missing bone. The most commonly used techniques, are the Two-staged delayed approach or the Simultaneous bone graft and implant placement technique.
Two Stage Delayed Sinus Bone Graft Technique
In the upper jaw when the posterior ( back ) teeth are lost, the bone that was supporting them resorbs (disappears ) and all that is left are the large air filled spaces (Sinuses) with no bone inside them.
Diagram ( Fig.1 ) shows adequate bone on one side  (A) for some implants vs insufficient or minimal bone under the Sinus cavity in the upper jaw on the opposite side (B).




In the most challenging cases where there is less than 3 or 4 millimeters of remaining bone in the posterior areas ( back of the mouth ), the two-stage surgical protocol is preferred. Six to nine months is needed for the new Sinus bone graft to become mature then another 6 months is required for "osseointegration"  ( bone to bond to the implant ) before the implants are ready to support a bridge. In the example below, the x-ray shows minimal bone in the anterior ( front) part of the mouth and large sinuses in the posterior area.
Preoperative CT scan ( Fig.2 ) reveals 1-3 millimeters of remaining bone on both the right and left sides of the upper jaw. All the teeth are missing and the patient had been wearing a denture for twenty years. She is a well controlled diabetic.

The Axial CT scans also revealed a severely resorbed anterior ridge  ( Fig.3 ) which is too narrow for implant placement in the front of the mouth.


For the patient described above, Sinus Elevation ( Lift ) bone grafts were performed on both sides of the mouth using the Two-stage delayed approach. ( Fig 4 )

Nine months later 8 dental implants were placed into the newly regenerated bone and submerged beneath the soft tissue to be allowed to heal undisturbed. After a healing period of 6 months, the implants bonded to the regenerated bone, the tops of the implants were uncovered (exposed) and a full arch bridge was made for the patient by her prosthodontist (Fig. 5). The bridge is beautiful, non removable, functions like her original teeth and leaves her palate free.

As of 2015 this patient has been wearing her non-removable bridge for 21 years and comes into the office for dental cleanings twice a year.
Simultaneous Bone Graft and Implant Placement
In other patient situations when there is more bone available, but not quite enough to cover the whole implant (Fig. 6 ), a bone graft may done at the same time as the implant placement. This is called Simultaneous Bone Graft and Implant Placement versus the Two-stage delayed approach.
