What Is a Sinus Lift?
A sinus lift (also called sinus augmentation) 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 graft material is placed to create a stable foundation for dental implants.
Why You May Need Sinus Augmentation
You may need a sinus lift if:
​
-
You have insufficient bone height in the upper jaw
-
Bone loss occurred due to missing teeth
-
Your sinuses are too close to the jaw for implant placement
-
You’ve experienced periodontal disease
-
This procedure allows patients who were previously not candidates for implants to move forward with treatment.
Types of Sinus Lift Procedures
​
Open Sinus Lift (Lateral Window Technique)
-
Used when more bone is needed. A small window is created in the jawbone to access the sinus.​
​​
Closed Sinus Lift (Osteotome Technique)
-
A less invasive option used when only a small amount of bone is required.
​
Your dentist will determine the best approach based on your anatomy and treatment goals.
Sinus Lift Procedure Step-by-Step
-
Local anesthesia is administered for comfort
-
A small opening is made in the bone
-
The sinus membrane is gently elevated
-
Bone graft material is placed
-
The site is closed and allowed to heal
​​
In certain cases, dental implants can be placed at the same time.
Recovery and Healing Timeline
-
Mild swelling and discomfort for a few days
-
Most patients return to normal activities within 1–2 days
-
Full healing typically takes 4–9 months before implant placement
​​
Following post-operative instructions is critical for proper healing.
Frequently Asked Questions
Is a sinus lift painful?
-
Most patients report minimal discomfort. The procedure is performed under local anesthesia, and any post-operative soreness is typically manageable with medication.
​
How long does sinus lift healing take?
-
Healing usually takes between 4 to 9 months, depending on the extent of the bone graft and individual healing factors.
​
What is the success rate of a sinus lift?
-
Sinus lift procedures have a very high success rate, typically over 90% especially when performed by an experienced dental professional.
​
Can dental implants be placed at the same time?
-
Yes, in certain cases implants can be placed during the same procedure. This depends on how much existing bone is available.
