The procedure is typically performed under local anesthesia, but sedation or general anesthesia may be used depending on patient comfort and the complexity of the procedure.

Surgical Access: An incision is made in the gum tissue where the back teeth used to be. The tissue is raised, exposing the bone underneath.

Lifting the Sinus Membrane: A small, oval window is opened in the bone, and the membrane lining the sinus on the other side of the window is gently pushed upward.

Bone Grafting Material: The space underneath the lifted sinus membrane is filled with a bone grafting material. The material can be taken from your own body (autogenous bone), from a cadaver (allogenic bone), from cow bone (xenograft), or can be a synthetic material.

 The gum tissue is stitched back into place.

Recovery and Healing
Healing Time: The healing process can take several months as the bone graft must integrate with the patient’s bone. After healing, dental implants can be placed.
Postoperative Care: May include pain relievers, antibiotics, and an antimicrobial mouthwash. Instructions will be given on diet and oral hygiene practices during the healing period.
Follow-up Appointments: To monitor the healing process and determine when implants can be placed.
Risks and Considerations

A risk during surgery, which can usually be repaired at the time of the procedure.
Postoperative Infection: As with any surgical procedure, there is a risk of infection.
Graft Failure: Rarely, the bone graft may not integrate well, necessitating further treatment.
A sinus lift is a common and generally safe procedure that can make dental implants possible for patients who otherwise wouldn’t be candidates due to insufficient bone in the upper jaw. It’s important to have a thorough consultation with a qualified dental specialist to understand the procedure, associated risks, and aftercare requirements.
