What Is Sinus Lifting?
Sinus lifting is a surgical procedure performed in the upper jaw, particularly in the molar region, when there is insufficient bone height to place dental implants. During this procedure, the floor of the sinus cavity is elevated, and a bone graft is added to create a solid foundation for stable implant placement.
Bone loss in the upper posterior jaw can occur due to tooth loss, natural bone resorption, sinus expansion, or prolonged edentulism. Sinus lifting increases the success rate of implant treatment by providing adequate bone support.
Why Is Sinus Lifting Done?
Sinus lifting is typically necessary in the following situations:
When bone height is insufficient
When planning implants in the upper jaw
When the sinus gradually descends, reducing available implant space
When bone volume is lost due to trauma or tooth extraction
This procedure ensures sufficient bone support in the upper jaw, helping implants achieve long-term stability.
Types of Sinus Lifting
Sinus lifting can be performed using two main techniques:
Open Sinus Lifting: Preferred when bone height is very limited. The gum is lifted, a window is opened in the jawbone, and the sinus membrane is carefully elevated. A bone graft is then placed. Healing usually takes 6-9 months.
Closed Sinus Lifting: Applied when bone height is relatively sufficient. The sinus floor is raised while preparing the implant site, and the graft is added. In this method, implant placement and sinus lifting can be done in the same session.
Sinus Lifting Procedure
The procedure is performed under local anesthesia and typically involves the following steps:
Bone height and sinus structure are evaluated using X-rays or CT scans.
The appropriate surgical technique is selected.
The sinus membrane is carefully elevated.
Bone graft material is placed into the cavity.
The area is closed, and the healing process begins.
Bone grafts can be derived from the patient’s own tissue, prepared bone powders, or synthetic materials.
Postoperative Care After Sinus Lifting
To ensure proper healing, patients should:
Avoid heavy physical activity for the first few days
Avoid keeping the mouth closed when sneezing or coughing
Avoid excessive pressure when cleaning the nose
Refrain from smoking and alcohol consumption
Take medications as prescribed by the dentist
Attend all follow-up appointments
During recovery, it is crucial that the bone graft integrates with the jawbone to provide a stable foundation for future implant placement.
