Bone Grafts & Sinus Lifts

Advanced Dentistry.

Bone grafts and sinus lifts are advanced techniques that allow patients to benefit from secure and durable implants. Although these procedures serve different purposes and are carried out in various regions of the jaw, they both aim to increase bone volume and establish a supportive foundation for dental implants.

If you are contemplating dental implants and a sinus lift or bone graft is recommended, it is crucial to have a comprehensive understanding of these procedures.

Bone Grafts

Bone grafts can be used in various areas of the jaw to augment bone volume. The choice of grafting material and technique depends on the individual’s specific clinical situation and personal preference. Bone grafts help to rebuild and strengthen the jawbone, providing a solid foundation for dental implants.

Sinus Lift

Otherwise known as sinus augmentation is a surgical procedure designed to allow an increase of the amount of bone in the upper jaw, specifically between the area of the premolars and molars. This is particularly important for patients who have experienced bone loss due to periodontal disease, tooth loss, or anatomical variations.

These procedures, especially coupled with the patient’s own PRF, can significantly impact the success of dental implants. Knowledge about the processes, recovery times, and potential risks can help patients make informed decisions and prepare for their dental journey.

Bone Grafts & Sinus Lifts FAQ

Why would I need dental bone grafting?

The jawbone plays a critical role in oral health, providing support for teeth and facilitating proper chewing function. When teeth are lost, over time, the corresponding jawbone area can undergo a process known as resorption, where the bone diminishes in density and volume due to a lack of stimulation.

Grafting will provide adequate jawbone to ensure dental implants can be securely anchored.

What is the source of the bone graft material?

Autograft: This is considered the gold standard for bone grafting, as it uses the patient’s own bone, minimizing the risk of rejection and complications. The bone is typically harvested from the chin, jaw, or another area of the mouth.
Allograft: This graft uses donor bone from a human source, which is processed and sterilized in specialized bone banks. Allografts reduce the need for additional surgical sites and can be a viable option for many patients.
Xenograft: Sourced from animals, usually bovine, xenografts provide a scaffold for new bone growth. These materials are processed to ensure that they are safe and biocompatible.
Alloplast: Synthetic bone grafts made from materials like hydroxyapatite or bioactive glass. These materials mimic the properties of natural bone and promote bone regeneration while avoiding the risks associated with biological grafts.

How do I prevent bone loss?

By replacing lost teeth with dental implants. The titanium posts inserted into the jawbone serve as artificial tooth roots. Implants not only restore function and aesthetics but also promote bone growth by providing the necessary cellular stimulation during biting and chewing. It is this interaction that will maintain the integrity of the bone and prevent degradation.

What is the procedure for a bone graft?

Depending on your situation, a bone graft may be performed either before your dental implant surgery or on the same day as the implant placement.

The bone grafting procedure is conducted under local anesthesia or other sedation options tailored to your preference, including sleep dentistry (IV sedation) or general anaesthesia. If necessary, your dentist may first extract bone from other areas of your mouth, unless donor tissue is being utilized. The harvested bone will then be transplanted to your jaw and covered with a membrane to facilitate healing.

What is the difference between a Socket Graft and a Block Graft?

A socket graft is a surgical procedure performed immediately after tooth removal, filling the empty socket with bone grafting materials to preserve the alveolar bone. This technique maintains the natural shape of the jawbone, facilitating future dental implants without extensive surgeries and reducing complications related to bone collapse.

A block bone graft addresses more serious jawbone loss by transplanting a piece of bone from another area or a donor into the jaw. This provides essential support for dental implants, with careful planning using CT scans and X-rays. Block bone grafts are ideal for patients with severe bone loss and boast a high success rate. They involve a harvest site and specialised surgical techniques.

How is the sinus ‘lifted”?

Preparation: Before the procedure begins, the patient undergoes a thorough evaluation, including imaging studies like X-rays or CT scans, to assess bone density and the anatomy of the sinus. Anesthesia is administered to ensure the patient is comfortable throughout the procedure.
Accessing the Sinus: A small circular incision is made in the gum tissue of the upper jaw, typically near the area where the molars were located. The gum tissue is carefully lifted to expose the bone. Ultrasonic piezoelectric equipment is then used to create a small window or access point in the bone of the upper jaw.
Elevating the Sinus Membrane: With careful maneuvering, a special instrument is used to gently lift the sinus membrane (the sinus floor). This step is critical, as the membrane must be elevated without tearing or damaging it. The elevation of the membrane creates a space directly above the jawbone and bone grafting material is introduced.
Closure: Following the bone grafting, your implant may placed, if indicated in your treatment plan. The access point in the bone is closed, and the gum tissue is sutured back into place. Aftercare include guidelines for pain management and oral hygiene practices. Follow-up appointments will be scheduled to monitor healing.

Does my body integrate with the graft?

Yes, with proper care and monitoring of the site after surgery will ensure:

Healing: Blood vessels form around the graft, providing nutrients and oxygen.
Ossification: New bone cells develop within the graft over several months.
Bone Remodeling: The graft material is replaced with new bone tissue, strengthening the area.

What is the recovery like after a bone graft?

Most patients recover within a few days to a week, but full healing and integration will take around 3 months. After surgery, you might feel some pain with swelling and bruising around the mouth and cheeks. We can prescribe painkillers to ensure your comfort. It’s important to be gentle around the graft area, rest and stick to a soft-food diet for the first few days to avoid disturbing the graft site.
