Sinus Lifting
Learn how sinus lifting creates enough bone to support dental implants in the upper jaw.

Sinus Lift for Dental Implants: What Patients Need to Know
Â
A sinus lift, also known as sinus augmentation, is a dental bone-grafting procedure that may be recommended when there is not enough bone in the upper back jaw to support a dental implant.
Â
For some patients who have lost upper molars or premolars, the maxillary sinus can be positioned close to the jawbone. Following tooth loss, the bone may also gradually shrink, leaving insufficient space for an implant. A sinus lift can increase the available bone and create a more suitable foundation for implant treatment.
Â
Why Might You Need a Sinus Lift?
Â
Dental implants need sufficient healthy bone around them to provide long-term support. In the back of the upper jaw, however, the amount of available bone can sometimes be limited by the position of the maxillary sinus.
After a tooth is lost, the surrounding bone can gradually resorb. At the same time, the sinus may expand into the space previously occupied by the tooth roots. As a result, there may not be enough vertical bone to place an implant in the desired position.
A sinus lift can help overcome this limitation by carefully raising the sinus membrane and placing bone-grafting material beneath it.
Â
How Does a Sinus Lift Work?
Â
The basic principle of a sinus lift is to create additional bone beneath the maxillary sinus.
During the procedure, the sinus membrane is carefully elevated and a suitable bone-grafting material is placed underneath it. The graft provides a space in which new bone can develop.
The exact technique depends on the amount of bone available, the location of the planned implant and the patient's individual anatomy.
Â
Types of Sinus Lift Procedures
Â
There are two commonly used approaches to sinus augmentation.
Â
Crestal Sinus Lift
Â
A crestal or internal sinus lift is performed through the area where the implant is planned. It may be appropriate when only a relatively small amount of additional bone is required.
Â
In selected cases, the dental implant can be placed during the same procedure if sufficient bone is available to achieve good initial implant stability.
Â
Lateral Window Sinus Lift
Â
A lateral window approach provides access to the sinus through the side of the upper jaw. It is generally considered when a greater amount of bone augmentation is required.
Â
The sinus membrane is carefully lifted and grafting material is placed underneath it. Depending on the amount of existing bone and the treatment plan, the implant may be placed at the same appointment or after a period of healing.
Â
Can a Dental Implant Be Placed at the Same Time?
Â
Sometimes, yes.
Â
Whether an implant can be placed at the same time as a sinus lift depends on several factors, including the amount and quality of the remaining bone and whether adequate initial implant stability can be achieved.
Â
If there is enough existing bone to securely stabilise the implant, simultaneous implant placement may be possible.
When there is insufficient bone for predictable initial stability, the sinus graft may need to heal before the implant is placed.
Â
Your treatment plan should therefore be based on your individual anatomy rather than a fixed approach for every patient.
Â
What Happens Before a Sinus Lift?
Â
Careful planning is an important part of sinus lift treatment.
Your dentist will assess your teeth, gums, bone levels and overall oral health. Three-dimensional imaging such as a CBCT scan may be recommended when more detailed information about the jawbone and maxillary sinus is needed.
Â
The scan can help assess:
Â
-
The height and width of the available bone
-
The position of the maxillary sinus
-
The anatomy of the sinus
-
The planned position and size of the dental implant
-
Whether bone grafting may be required
-
Whether implant placement can potentially be performed at the same time
Â
This information helps create a treatment plan tailored to your individual circumstances.
Â
What Bone Graft Material Is Used?
Â
Different bone-grafting materials can be used for sinus augmentation. These may include materials derived from the patient's own bone, human donor bone, animal-derived materials or synthetic bone substitutes.
Â
The most appropriate material depends on the individual clinical situation and the treatment approach being used.
Â
Is a Sinus Lift Painful?
Â
A sinus lift is performed using appropriate local anaesthesia, so you should not feel pain during the procedure.
Some swelling, tenderness, pressure or bruising can occur afterwards. Your dentist will provide postoperative instructions to help support healing and minimise complications.
Â
Most patients can manage the recovery with appropriate aftercare and medication when required.
Â
What Should You Avoid After a Sinus Lift?
Â
Because the procedure involves the sinus area, protecting the surgical site during healing is particularly important.
Â
Your dentist may advise you to avoid activities that create significant pressure within the sinus, such as forceful nose blowing. You may also receive specific instructions regarding exercise, flying, sneezing and other activities depending on the procedure performed.
Â
Always follow the postoperative instructions provided specifically for your treatment.
Â
How Long Does a Sinus Lift Take to Heal?
Â
Healing varies from patient to patient.
Â
The required healing period depends on factors such as the surgical technique, the amount of bone grafting, the condition of the existing bone and whether an implant was placed at the same time.
Â
When the implant cannot be placed immediately, the graft may be allowed to mature before implant placement. Your dentist can assess the healing process and determine when the next stage of treatment should proceed.
Â
Are There Risks With a Sinus Lift?
Â
Like any surgical procedure, a sinus lift has potential risks and complications.
Â
One of the most important considerations is the sinus membrane. It is a delicate structure and can sometimes become perforated during the procedure. Other possible complications include infection, graft complications, postoperative sinus symptoms or inadequate bone formation.
Â
Existing sinus problems may also be relevant when planning treatment.
Â
This is why proper assessment, appropriate imaging and careful surgical planning are important before proceeding with sinus augmentation.
Â
Is a Sinus Lift Always Necessary for Upper Jaw Implants?
Â
No.
Â
Not every patient receiving an upper dental implant needs a sinus lift.
Â
Some patients have sufficient bone beneath the sinus for conventional implant placement. In other cases, alternative treatment approaches may be possible depending on the location of the missing tooth, available bone and the desired implant position.
Â
A sinus lift is recommended only when it is appropriate for the individual treatment plan.
Â
Sinus Lift and Dental Implants
Â
A sinus lift can be an important part of dental implant treatment when bone loss and the position of the maxillary sinus limit the available space for an implant.
Â
The goal is to create a suitable foundation for the implant while maintaining the health and function of the surrounding structures.
If you have been told that you do not have enough bone for an implant in the upper back jaw, this does not necessarily mean that dental implants are impossible. A sinus lift or another form of bone augmentation may provide an appropriate solution.
Â
Considering Dental Implants?
Â
If you are considering dental implants and have been told that you have insufficient bone in the upper jaw, an assessment can determine whether sinus augmentation is appropriate for you.
