Dentist in Mira Road A sinus lift refers to the augmentation or lifting up of the maxillary sinus to make more room for new bone.
Maxillary sinuses are Air filled cavities that are located just above the back portion of the maxilla or upper jaw.
Maxillary sinus floor augmentation is also termed as Sinus lift, Sinus graft or sinus procedure.
It is a surgical procedure which aims to increase the amount of bone in the upper jaw i.e the area of premolar and molar by placing a bone graft.

When a tooth is lost, the alveolar process begins to remodel. The vacant tooth socket collapses as it heals leaving a toothless area. This collapse causes a loss in both height and width of the surrounding bone. Also, when a maxillary molar or premolar is lost, the maxillary sinus pneumatizes in this region which further diminishes the thickness of the underlying bone. Due to all these reasons there is a loss in volume of bone that is available for implantation of dental implants which rely on osseointegration (bone integration), to replace missing teeth. Basically The goal of the sinus lift is to graft extra bone into the maxillary sinus, so more bone is available to support a dental implant.
The graft material used can be either
- an autograft:- Patient’s own tissue
- an allograft:- Graft/ tissue taken from another patient
- a xenograft:-Graft/ tissue taken from animal
- an alloplast:- A growth factor infused collagen matrix
Once the graft has been placed It takes about six to eight months for the sinus augmentation bone to become part of the patient’s natural sinus floor bone (dentist in mira road).
We have to wait for atleast six months before implants are attempted. However, some surgeons perform both the augmentation and dental implant simultaneously, to avoid the necessity of two surgeries.
