What Is A Sinus Lift and What You Need To Know About It

 

A sinus lift, also called sinus augmentation, is a surgical operation performed by dental specialists to increase the volume of bone in the upper jaw that may be necessary if the upper jaw requires dental implants. Placing an implant with no bone reinforcement raises the risk of the implant’s failure but can also induce sinus membrane blockage. The bone in that area no longer gets the stimulation it needs to grow, resulting in bone loss.

Why Would You Need A Sinus Augmentation?

There are a few particular explanations of why someone requires a dental sinus lift operation. For instance:

Generally speaking, where the bone in the upper jaw does not support dental implants, sinus lifting is required. Bone density in that part of the mouth declines quickly after a tooth loss. Consequently, the bone loss makes a correct dental implant placement impossible.

What Happens Before a Sinus Lifting Procedure?

The three most common forms of bone used in sinus lift surgeries are autogenous bone surgery, allogeneic bone surgery, and xenograft.

Autogenous bone is the bone that comes from your own body. The specialist extracts it from other parts of the body or teeth. In certain circumstances, the surgeon takes the bone from the hip or tibia of the recipient.

Allogenic bone is the bone that comes from a cadaver.

Lastly,  the xenograft technique consists of using the bone of a cow.

An X-rays will help define the bone source so that the surgeon or dental expert can examine the jaw and sinus anatomy.

How Is The Sinus Lifting Procedure Operated?

During the operation day, the surgeon makes an incision in the gum line where the posterior teeth used to exist. The tissue is lifted from the surface until the incision is done.

Afterward, the surgeon creates a small, circular window in the bone itself using a specific tool.  This window provides the surgeon with a direct and clear view of the sinus. Then, he will gently pull up the jaw membrane leaving the way to see the jaw bone itself.

The following step is inserting a few granules of graft material into the missing tooth gap. Although the amount of graft varies, it is crucial to develop bone growth.

After grafting the bone, the specialist will close the tissue with a few stitches. Then, time is given for the bone to heal. A few months later, the treated area will be ready for dental implants placement.

When Should You Contact A Professional After The Sinus Lifting Procedure?

What Are the Risks of The Sinus Lift Treatment?

As with any surgery or procedure, sinus lift treatment implies some risks. The biggest threat is that it could puncture or tear a sinus membrane. Your surgeon will aim to resolve it if this occurs, but if it is not successful, he will delay your operation to a later date. As in every surgical operation, infection represents a major risk.
