Bone Grafting and Sinus Lift Procedure

A sinus lift/augmentation is a surgical procedure performed by an oral and maxillofacial surgeon or periodontist. In the procedure, the bone mass is increased in the upper jaw to accommodate the titanium post of the implant. The sinus membranes on both sides of the nose can be operated and lifted higher for placing bone graft. With time and better technology, sinus lifts have become common as more patients now opt for dental implants than traditional dental restoration solutions.

Why Get Sinus Lift?

A sinus lift is required when the bone height and mass are insufficient in the upper jaw or if the distance between sinuses is too little to load the implant. A sinus lift is an ideal procedure to increase the foundation volume for the implant so it may strongly fuse with the bone.
The following cases qualify for a sinus lift procedure:

  • If a patient has too many teeth lost in the upper jaw and the bone has either weakened or is in an inoperable state.
  • The upper jaw bone has been weakened or significantly eroded due to disease such as periodontal (gum) disease.
    Excessive loss of teeth ultimately weakens the jaw itself. In such cases, it becomes imperative to increase the bone volume before inserting dental implants.
  • When the maxillary sinus and jaw bone are too close, it becomes necessary to opt for a sinus lift to qualify for dental implants.

Getting Ready For A Sinus Lift

Sinus lift requires additional bone, which can be extracted from the patient’s own body, a donor or even a cow. Complete X-Ray of the complete jaw and a special type of CT scan will be taken, so the dentist can accurately measure dimensions of the bone and determine the overall health of the sinus. The patient must also inform the maxillofacial surgeon of any seasonal allergies he/she has so the procedure may be scheduled when the allergies are not active. We routinely does sinus bone grafting and and our success rate is in par with the global success rate. 

  • The Procedure

The dental surgeon will begin with an incision at the precise point where the teeth were and will lift the tissue to directly access the bone. A selective, small opening in the bone will be made and the sinus membrane between the jaw and sinus will be lifted upwards. From here, the bone material is added to the secured space, which usually ranges between millimetres.
Once the graft has been added, the incision is closed with stitches so the gum tissue can heal. A period of 4-9 months is given so the graft material can completely mesh with the bone and create a strong base for the implant to load in.
