Building Bone in the Upper Jaw for Dental Implant Placement
When dental implants are planned for the upper back jaw, there must be enough bone beneath the maxillary sinus to securely support them. For some patients, bone loss or the natural position of the sinus leaves insufficient vertical bone for implant placement.
Sinus lift surgery, also called sinus augmentation, is a bone grafting procedure used to increase available bone in the upper jaw beneath the maxillary sinus. By carefully creating additional space and placing bone graft material in the area, the procedure can help establish a stronger foundation for future dental implants.
At Beverly Hills Cosmetic & Implant Center, 3D imaging can be used to evaluate the upper jaw, available bone, and sinus anatomy as part of comprehensive dental implant planning.
When a sinus lift is necessary, the procedure is coordinated with the overall implant treatment plan according to the patient’s individual anatomy and restorative needs.

What Is a Sinus Lift?
A sinus lift is a type of dental bone augmentation performed in the posterior, or back, portion of the upper jaw.
The maxillary sinuses are air-filled spaces located above the upper premolar and molar regions. The amount of bone separating the mouth from the sinus varies from person to person.
When there is not enough vertical bone to support a dental implant, sinus augmentation can be used to increase the amount of bone available.
During the procedure, the membrane lining the sinus is carefully elevated to create space for bone graft material. The graft is placed beneath the elevated membrane, allowing the area to heal and develop additional bone for implant support.
Why Might You Need a Sinus Lift Before Dental Implants?
Not everyone receiving an upper dental implant needs sinus augmentation.
The procedure may be considered when there is insufficient bone height between the mouth and the maxillary sinus for the planned implant.
This may occur because of:
- Long-term tooth loss
- Previous tooth extractions
- Natural sinus anatomy
- Bone resorption after losing teeth
- Periodontal disease
- Previous infection
- Individual jaw anatomy
After upper back teeth are lost, the surrounding jawbone can gradually remodel and decrease in volume.
At the same time, the maxillary sinus may occupy more of the available space in this region, leaving less bone for implant placement.
A sinus lift can help address this limitation when additional vertical bone is necessary.
How Do We Determine if a Sinus Lift Is Necessary?
A visual examination alone cannot provide all of the information needed to evaluate the relationship between the upper jaw and maxillary sinus.
Three-dimensional imaging is particularly useful when planning implants in this region.
At Beverly Hills Cosmetic & Implant Center, cone-beam computed tomography (CBCT) can provide detailed 3D information about:
- Available bone height
- Bone width
- Maxillary sinus position
- Sinus anatomy
- Planned implant location
- Surrounding anatomical structures
This information helps determine whether sufficient bone is already available or whether sinus augmentation should be incorporated into the dental implant treatment plan.
How Does Sinus Lift Surgery Work?
The exact procedure varies according to the amount of existing bone and the planned implant treatment.
In general, sinus augmentation involves carefully accessing the area beneath the maxillary sinus and elevating the sinus membrane.
Bone graft material is then placed into the newly created space.
The graft provides a framework that supports the body’s natural bone-healing process. As the area heals, new bone can develop and mature within the grafted region.
This can increase the amount of bone available to support a dental implant.
Can a Sinus Lift and Dental Implant Be Done at the Same Time?
In some cases, sinus augmentation and dental implant placement can be performed during the same procedure.
In other cases, the grafted area needs to heal before the dental implant is placed.
Whether simultaneous treatment is appropriate depends on factors such as:
- Amount of existing bone
- Ability to achieve adequate implant stability
- Extent of sinus augmentation required
- Bone quality
- Individual sinus anatomy
- Overall oral health
- Planned implant position
When there is adequate existing bone to provide appropriate initial implant stability, simultaneous placement may be considered.
When the available bone is more limited, a staged approach may be recommended so the sinus graft can heal before implant placement.
Your 3D evaluation helps determine the appropriate sequence.
Sinus Lift vs. Other Dental Bone Grafts
A sinus lift is a type of bone augmentation, but it is specifically designed for the posterior upper jaw near the maxillary sinus.
Other bone-grafting procedures address different anatomical needs.
For example:
Socket preservation may be performed when a tooth is extracted to help maintain bone at the extraction site.
Ridge augmentation may be used to rebuild areas where the jawbone has become deficient in width, height, or contour.
Guided bone regeneration (GBR) uses grafting material and a barrier membrane to support bone formation in a deficient area.
Sinus augmentation specifically creates additional bone beneath the maxillary sinus when more vertical bone is needed for implants in the upper back jaw.
Some implant cases may require more than one type of bone augmentation depending on the anatomy.
What to Expect With Sinus Lift Surgery
Consultation & 3D Evaluation
Your teeth, gums, jawbone, missing-tooth area, and overall oral health are evaluated.
CBCT imaging provides three-dimensional information about the maxillary sinus and available bone.
Personalized Treatment Planning
The amount of existing bone and planned implant position are evaluated to determine whether sinus augmentation is necessary.
Your treatment plan will also establish whether the implant may be placed at the same appointment or after the graft has healed.
Sinus Augmentation
The treatment area is anesthetized for comfort.
The sinus membrane is carefully elevated, and bone graft material is positioned beneath it according to the treatment plan.
Healing
The grafted area requires time for bone development and maturation.
Healing time varies according to the extent of augmentation, amount of existing bone, grafting approach, individual healing, and whether an implant was placed at the same time.
Dental Implant Treatment
If implant placement was not performed simultaneously, the area is evaluated after appropriate healing to determine when the implant can be placed.
Recovery After Sinus Lift Surgery
Recovery varies according to the extent of treatment and whether additional procedures are performed at the same appointment.
Patients may experience temporary:
- Swelling
- Soreness
- Tenderness
- Minor bleeding
- Bruising
- Nasal or sinus-related sensations
Because the procedure involves an area close to the sinus, following postoperative instructions is particularly important.
Patients may be instructed to temporarily avoid activities that create pressure within the sinus, such as forceful nose blowing. Specific restrictions and their duration depend on the individual procedure.
You will receive personalized postoperative instructions regarding oral hygiene, diet, physical activity, medications when appropriate, and protection of the surgical area.
How Long Does a Sinus Lift Take to Heal?
Initial soft-tissue healing occurs before the underlying graft has fully matured.
Bone development after sinus augmentation generally requires several months, although the exact healing period varies considerably.
Factors that can influence healing include:
- Amount of bone grafting performed
- Existing bone volume
- Grafting technique
- Whether an implant was placed simultaneously
- Smoking or tobacco use
- Overall health
- Oral hygiene
- Individual healing response
If your implant treatment is staged, the grafted area will be evaluated after healing to determine when implant placement can proceed.
Sinus Augmentation as Part of Dental Implant Planning
The purpose of sinus lift surgery is not simply to add bone. The augmentation should be planned according to the position and requirements of the future dental implant.
At Beverly Hills Cosmetic & Implant Center, implant planning considers the relationship between the available bone, sinus anatomy, proposed implant position, and final restoration.
This comprehensive approach helps determine whether sinus augmentation is necessary and how it should fit into the overall treatment sequence.
Frequently Asked Questions About Sinus Lift Surgery
A sinus lift, or sinus augmentation, is a bone-grafting procedure used to increase bone in the back portion of the upper jaw beneath the maxillary sinus. It is commonly performed when additional bone is needed to support dental implants.
A sinus lift may be recommended when there is insufficient vertical bone between the mouth and maxillary sinus to support the planned implant. This can occur because of long-term tooth loss, previous extractions, bone loss, or natural sinus anatomy.
No. Many patients have adequate bone for implant placement without sinus augmentation. CBCT imaging can help determine how much bone is available and whether additional augmentation is necessary.
Sometimes. If enough existing bone is present to provide appropriate implant stability, the implant and sinus augmentation may be performed during the same procedure. When there is more significant bone deficiency, the graft may need to heal before implant placement.
A sinus lift is a specific type of dental bone graft. It adds bone beneath the maxillary sinus in the posterior upper jaw. Other bone grafting procedures, such as socket preservation or ridge augmentation, are used for different anatomical situations.
The timeline varies. Some patients receive implants at the same time as sinus augmentation, while staged cases require a healing period before implant placement. The amount of existing bone, graft size, healing response, and treatment approach all influence timing.
Local anesthesia is used during the procedure to maintain comfort. Patients can experience temporary soreness, swelling, tenderness, or other postoperative symptoms afterward. Specific recovery experiences vary by patient and the extent of surgery.
Not every patient with limited upper-jaw bone requires the same treatment. Implant position, available bone, anatomy, and the type of restoration being planned all influence the options. A 3D evaluation is necessary to determine whether sinus augmentation is needed or whether another implant approach may be appropriate.
