Maxillary Sinus Lift

A sinus lift is a surgical procedure that aims to increase the bone volume in the upper back jaw. This technique is used when there is not enough bone to place dental implants. The maxillary sinus is an air-filled cavity located above the upper back teeth. During the procedure, the surgeon gently lifts the sinus membrane (Schneiderian membrane) and adds bone graft material into the space created. This process, also known as sinus floor elevation, creates a solid base for the placement of implants. The procedure can be performed using a lateral or crestal approach, depending on the amount of remaining bone available.

Types of Sinus Lift Procedures

There are two main sinus lift techniques: the lateral approach and the crestal approach. The lateral approach involves opening a bony window in the lateral wall of the maxillary sinus to access the sinus membrane. This technique allows for greater bone augmentation (average 8.5 mm) and is indicated when the residual bone height is less than 5-6 mm. The less invasive crestal approach uses osteotomes inserted through the alveolar crest to gently elevate the sinus floor. It is best with at least 5-6 mm of residual bone and allows for an average augmentation of 4-5 mm. The choice between the two techniques depends primarily on the patient's anatomy and the amount of available bone. Both procedures have demonstrated comparable long-term implant success rates.

The breast lift process step by step

The sinus lift process begins with a thorough evaluation using x-rays and CT scans. The surgeon examines the anatomy of the sinus and jaw to plan the procedure. On the day of surgery, local anesthesia or sedation is administered. The surgeon makes an incision in the gum to expose the bone and creates a small window to access the sinus membrane. The membrane is gently lifted to create space for the bone graft. The graft material is placed into the space created to stimulate the growth of new bone. Finally, the incision is stitched shut. The healing period lasts several months, during which the new bone integrates with the existing bone, creating a solid foundation for dental implants.

Risks and potential complications

Sinus lifts, while generally safe, do carry some risks. The most common complication is sinus membrane perforation, which occurs in 10-34% of cases. Perforations less than 5 mm have an implant survival rate of 97.14%, but this rate decreases significantly for larger perforations. Other possible complications include sinus infection, sinusitis, bleeding, and swelling. Acute postoperative sinusitis occurs in 10-20% of patients, while chronic sinusitis occurs in 4-8%. Risk factors include tobacco use and a history of sinus disease. In rare cases, nerve damage or implant failure may occur. Proper preoperative evaluation and careful surgical technique can significantly reduce these risks.

Conclusion

Sinus lift is a fundamental solution for those who want dental implants but have little bone in the upper jaw. This procedure, although it carries some risks, has a significant impact on the quality of life of patients, allowing them to recover functionality and smile. The choice between lateral and crestal approaches, together with a careful pre-operative evaluation, are key factors in the success of the procedure.

For those considering this option, it is essential to be well informed and consult with an experienced professional. A thorough understanding of the process, risks and benefits helps you make an informed decision. To get started on this journey, you can book a free consultation at our Go Health Albania clinic.

FAQs

Question: How is a sinus lift performed?
Answer: A sinus lift is performed by moving the membrane between the maxillary sinus bone and the jaw upwards to create a space. The transplanted material is then inserted into this space, the amount of which varies but is generally a few millimetres.

Question: What should you avoid doing after a sinus lift?
Answer: After a sinus lift, it is advisable not to drive or ride a bicycle for the first 2 hours. It is also important not to spit or rinse your mouth for the first 2-3 hours after the procedure.

Question: How long does a sinus lift procedure take?
Answer: The duration of a maxillary sinus lift procedure varies depending on the complexity of the case, but generally ranges between 1 and 2 hours.
