Sinus Lift

Sinus lifts are sometimes required when we lose upper molar teeth. 2 things can happen that complicate restoration of the area:

  1. There is loss of the volume of bone
  2. There is also a downward expansion of the maxillary sinus. A sinus simply means an air filled space encapsulated within bone. As it is in the maxilla, it is called the maxillary sinus.

 

With restoration of the posterior maxilla (upper jaw), the amount of available bone with which we can place dental implants is the bone volume between the gum ridge and the bottom of the sinus. This is often small and ever decreasing.

At great way to increase this volume is to lift the floor of the sinus back up to where it was. This process is called a sinus lift.

The careful lifting of the sinus membrane leaves a cavity that can easily be filled with bone, artificial bone or osteoinductive/conductive material.

Implants can often be placed simultaneously with a very high success rates. New oscillating bone cutting machines make this procedure very predictable, relatively simple and pain free.

This is a very common procedure as the posterior maxilla is very quick to give up its bone volume after tooth loss.

F.A.Q.

As compared to implant placement alone, only marginally. Again, the less soft tissue manipulation and damage, the less down time. This is a general rule that can be applied to all oral surgical procedures.

No. The nose is totally separate. Also, complications only arise of the sinus membrane is torn or perforated. Usually, even this is no big deal, but when the membrane remains intact, the success rates without complication are very high. Modern piezo machines make this eventuality unlikely, greatly enhancing the success rates of the procedure.
