There are many reasons why individuals get a sinus-lift surgery, but according to Colgate, the primary reason for getting this procedure done is because there is not enough bone height in the upper jaw. This means the sinuses are too close to the jaw for a dental implant procedure.

Tooth loss and gum disease are some of the primary reasons why the bone in this area goes missing, states Colgate. In some individuals, the maxillary sinus is just naturally too close to the upper jaw for implants, as the size of the sinuses vary among individuals, and the sinuses can grow larger during the aging process, making sinus-lift surgery the only option.

The surgical process starts with a bone graft, and then four to nine months later, an implant is put in place, according to Colgate, allowing the grafted mesh inserted in the jaw to mesh with the existing bone.
