If you’ve been told you don’t have enough bone in your upper jaw for dental implants, your dentist may recommend sinus augmentation. This advanced procedure increases the amount of bone beneath the sinus cavity, creating a strong foundation for long-lasting dental implants.
At Riverplace Periodontics, our experienced specialists provide personalized treatment plans to help patients restore their smiles with confidence. Whether you’re considering dental implants or have been advised to undergo a sinus augmentation procedure, understanding the process can help you make informed decisions about your oral health.

What Is Sinus Augmentation?
Sinus augmentation, also called a sinus lift, is a surgical procedure that adds bone to the upper jaw in the area of the molars and premolars. The sinus membrane is gently lifted, and bone grafting material is placed beneath it to increase bone height.
This additional bone creates the support needed for successful dental implants placement.Patients who have experienced bone loss due to missing teeth, gum disease, or natural anatomy often benefit from sinus augmentations before dental implants.
Why Is Sinus Augmentation Needed Before Dental Implants?
Dental implants require sufficient jawbone to remain stable over the long term. Unfortunately, the upper back jaw naturally has less bone than other areas of the mouth.
Common reasons patients need sinus augmentation before dental implants include:
- Bone loss after tooth extraction
- Advanced periodontal disease
- Naturally large sinus cavities
- Long-term missing teeth
- Insufficient bone for implant placement
Without enough bone, implants may not integrate properly, increasing the risk of implant failure.

How to Know If You Need Sinus Augmentation?
You may benefit from a sinus augmentation if you:
- Want dental implants in the upper back jaw
- Have been told you lack adequate bone height
- Have experienced jawbone deterioration
- Are in good overall health
- Maintain healthy gums
A comprehensive examination and 3D imaging help determine whether a sinus lift is the right solution.
Understanding the Sinus Augmentation Procedure
The sinus augmentation procedure is carefully planned to maximize safety and long-term success.
Step 1: Comprehensive Evaluation
Your periodontist evaluates your oral health using digital X-rays and CBCT imaging to assess bone volume and sinus anatomy.
Step 2: Local Anesthesia
The treatment area is numbed for your comfort. Sedation options may also be available.
Step 3: Creating Access
A small opening is made in the upper jawbone near the missing tooth area.
Step 4: Lifting the Sinus Membrane
The sinus membrane is gently elevated to create space for bone graft material.
Step 5: Bone Grafting
Bone graft material is carefully placed beneath the sinus membrane to increase bone height and create a stable foundation for dental implants.
Step 6: Healing
The area is closed with sutures, allowing the graft to integrate naturally with your existing bone.

Sinus Augmentation Recovery
Most patients experience a smooth augmentation recovery with minimal discomfort.
During Recovery You May Notice:
- Mild swelling
- Slight bleeding
- Nasal congestion
- Minor discomfort
- Bruising around the cheeks
These symptoms typically improve within several days.
Recovery Tips
- Avoid blowing your nose.
- Sneeze with your mouth open.
- Take prescribed medications as directed.
- Eat soft foods for several days.
- Avoid smoking during healing.
- Follow all post-operative instructions.
Complete bone healing usually takes 4 to 9 months, depending on the individual and the graft material used.
Sinus Augmentation Cost
The sinus augmentation cost varies based on several factors, including:
- Complexity of the procedure
- Amount of bone graft needed
- Type of graft material
- Whether sedation is used
- Insurance coverage
- Additional implant treatment
Because every patient’s oral health needs are different, the cost of sinus augmentations varies based on the complexity of the procedure and your personalized treatment plan. During your consultation, your periodontist will provide a detailed cost estimate and discuss available financing options to help make treatment more affordable.
