Sinus augmentation, also known as sinus lift surgery or sinus grafting, is a dental procedure designed to increase the amount of bone in the upper jaw, specifically in the area of the maxillary sinuses. This procedure is often necessary for individuals who have experienced bone loss in the posterior upper jaw or have insufficient bone height to support dental implants.

Here’s an overview of the sinus augmentation process:


  • Bone Insufficiency: Sinus augmentation is commonly performed when there is insufficient bone height in the upper jaw, particularly in the premolar and molar regions.
  • Tooth Loss: Individuals who have lost one or more upper back teeth may experience bone resorption over time, necessitating augmentation for implant placement.

Preoperative Evaluation:

  • Before the sinus augmentation procedure, thorough diagnostic imaging, such as X-rays or CT scans, is conducted to assess the current bone density and sinus anatomy.
  • The dentist evaluates the patient’s medical history and overall oral health to determine the suitability for the procedure.

Surgical Procedure:

  • Incision: The procedure typically begins with a small incision in the gum tissue at the site of the intended implant.
  • Access to Sinus Cavity: A small opening is made in the bone, providing access to the sinus cavity.
  • Lift and Graft: The sinus membrane is gently lifted upward, and a bone graft material is placed in the space created between the jaw and the sinus membrane. The bone graft may consist of the patient’s own bone, donor bone, or synthetic materials.
  • Closure: After the grafting material is placed, the incision is closed with sutures.

Healing and Integration:

  • Over the next several months, the bone graft integrates with the existing bone, promoting the growth of new bone.
  • During the healing period, patients may be advised to avoid strenuous physical activities and follow postoperative care instructions.

Implant Placement:

  • Once the augmented area has healed and gained sufficient bone density, dental implants can be placed in the upper jaw to support prosthetic teeth.

Follow-up Care:

  • Regular follow-up appointments with the dental team are essential to monitor healing progress and ensure the success of the implant placement.
Sinus augmentation is a well-established and effective procedure that has enabled many patients with insufficient bone in the upper jaw to benefit from dental implants. It allows for the restoration of missing teeth and the improvement of oral function and aesthetics. However, individual outcomes may vary, and the success of the procedure depends on factors such as the patient’s overall health and adherence to postoperative care instructions.
