When the upper back jaw does not have enough bone to support a dental implant, the problem is often related to the location of the sinus cavity above the missing teeth. A sinus augmentation, sometimes called a sinus lift, can create additional bone height in this area so implant treatment may become possible.
Dr. Anil Dwivedi will evaluate the amount of available bone, the position of the sinus and the planned implant site before determining whether sinus augmentation is appropriate. The procedure is not necessary for every upper-jaw implant case, but it can be an important step when existing bone volume is insufficient.
Why the Upper Jaw Sometimes Needs More Bone
The bone in the back portion of the upper jaw can become thinner after teeth are lost. At the same time, the sinus cavity may extend into the area where implant support is needed, leaving limited bone between the mouth and the sinus.
A dental implant needs adequate bone around it for stability. If the available bone is too limited, our dentist may recommend sinus augmentation before or in conjunction with implant placement.
The goal is to create a stronger foundation in an area where natural anatomy or previous bone loss has reduced the available support.
How a Sinus Augmentation Works
During sinus augmentation, our dentist carefully accesses the bone beneath the sinus and gently elevates the sinus membrane. Bone grafting material is then placed in the newly created space.
Over time, the grafted area is intended to develop into a more substantial volume of bone that can support an implant. The exact technique depends on how much existing bone is present and the amount of additional height needed.
In some cases, the implant may be placed during the same procedure. In others, the graft is allowed to heal first before implant placement is completed.
How We Determine Whether You Need a Sinus Lift
The decision begins with imaging and a clinical evaluation rather than with symptoms alone. You may not be able to tell that bone height is limited simply by looking at the area or noticing how it feels.
Our dentist may use CBCT imaging to view the sinus, remaining bone and nearby anatomy in three dimensions. This can help determine how much bone is available and whether sinus augmentation would improve the implant site.
The scan can also help our dentist plan the location and dimensions of the future implant more precisely.
When Sinus Augmentation May Be Recommended
A sinus lift may be considered when an implant is planned for the upper premolar or molar region and there is not enough vertical bone beneath the sinus. Reasons for limited bone may include:
- Bone loss after a tooth has been missing for an extended period
- Natural anatomy that places the sinus close to the tooth roots
- Bone changes related to periodontal disease
- Previous extractions that resulted in reduced ridge height
- The need for additional support before implant placement
Our dentist will determine whether grafting is needed based on your imaging and the requirements of the planned implant rather than using the same approach for every patient.
What to Expect During the Procedure
The area is anesthetized before treatment begins. Depending on the technique selected, our dentist creates access to the sinus area, carefully elevates the membrane and places the graft material beneath it. Once the graft has been positioned, the surgical area is closed and allowed to heal. If the implant is being placed at the same appointment, that step is completed according to the treatment plan.
You will receive instructions about eating, cleaning the area and protecting the surgical site during recovery.
Can an Implant Be Placed at the Same Time?
Sometimes. Whether the implant can be placed during sinus augmentation depends largely on how much native bone is present and whether the implant can achieve sufficient initial stability. If there is enough existing bone to support the implant securely, simultaneous placement may be possible. If not, our dentist may recommend allowing the graft to heal first and placing the implant later. The safest sequence is determined by the anatomy and stability of the site rather than by trying to shorten treatment time unnecessarily.
Healing After Sinus Augmentation
Some swelling, tenderness or minor bruising can occur after treatment. You may also receive specific instructions designed to avoid unnecessary pressure changes in the sinus area during early healing.
Our team can review your postoperative care instructions with you, while our dentist will determine whether follow-up evaluation is needed. It is important to follow the directions you receive because the grafted area needs time to stabilize and heal.
If you develop increasing pain, persistent bleeding, unusual drainage or another symptom that concerns you, contact the office so our dentist can evaluate the area.
How Sinus Augmentation Supports Implant Treatment
The purpose of a sinus lift is not simply to add bone. The added bone is intended to create the support needed for future implant placement in an area where the original anatomy would otherwise make treatment more difficult.
Dr. Dwivedi has placed more than 1,000 dental implants and completed more than 1,000 implant restorations during his career. He has also completed more than 500 hours of continuing education related to implant dentistry.
That combination of surgical and restorative experience helps support treatment planning that considers both the grafted site and the final tooth replacement from the beginning.
Benefits of Sinus Augmentation
When additional bone is needed in the upper back jaw, sinus augmentation may provide several advantages:
- Creates additional bone height for implant placement
- May expand implant treatment options in areas with limited bone
- Helps establish a stronger foundation for upper-jaw implants
- Allows implant placement to be planned around individual sinus anatomy
- May reduce the need to avoid an otherwise useful implant location
The amount of benefit depends on your anatomy, the condition of the existing bone and the implant plan developed for your case.
Sinus Augmentation as Part of Oral Surgery
A sinus lift is one type of oral surgery that may be used to prepare a site for future restorative treatment. It is usually recommended because of a specific anatomical limitation rather than as a routine step for every dental implant.
Our dentist will explain why the procedure is being considered, how much grafting is expected and when implant placement may occur.
Understanding how the graft fits into the larger treatment plan can make the sequence of care easier to follow.

Frequently Asked Questions About Sinus Augmentation
What is sinus augmentation?
Sinus augmentation is a bone-grafting procedure used to increase bone height in the back portion of the upper jaw. It may be recommended when there is not enough bone beneath the sinus to support a dental implant.
Is a sinus lift required for every upper dental implant?
No. Many upper-jaw implants can be placed without sinus augmentation. Our dentist will review your imaging and determine whether the available bone is sufficient for the implant being planned.
Why does bone decrease beneath the sinus?
Bone can shrink after teeth are lost, and some people naturally have less bone between the mouth and sinus cavity. Periodontal disease and previous extractions may also contribute to reduced bone volume.
Can a dental implant be placed during the sinus lift?
Sometimes. If enough existing bone is available to provide initial implant stability, simultaneous placement may be considered. Otherwise, our dentist may allow the graft to heal before placing the implant.
How is a sinus lift planned?
Our dentist will use your examination and dental imaging to evaluate the remaining bone and sinus anatomy. CBCT imaging may be used when three-dimensional information is needed for more detailed planning.
How long does a sinus graft take to heal?
Healing time varies based on the size of the graft, the amount of existing bone and whether an implant was placed at the same time. Our dentist will monitor healing and determine when the site is ready for the next stage of treatment.
What should I avoid after sinus augmentation?
You may receive instructions intended to minimize pressure around the sinus and protect the graft while it begins to heal. Follow the specific directions provided for eating, cleaning and physical activity after your procedure.
How do I find out if I need a sinus lift?
Call 703-734-1080 to make an appointment with our dentist. We can evaluate the planned implant site, review your imaging and determine whether sinus augmentation is necessary.
