Bone grafting

What is Bone Grafting

PM Oral Surgery performs bone grafting procedures aimed at regenerating lost jawbone. There are many reasons why bone loss occurs. For example, dental extractions can encourage jawbone to resorb due to lack of stimulation, periodontal disease and infection can also trigger bone loss. Bone loss can eventuate over years due to direct trauma or injury, even misaligned teeth can cause bone deterioration. Other reasons for performing a bone grafting procedure may include bone loss as a result of a sinus deficiency, a birth defect or osteomyelitis (a bacterial infection in the bone or bone marrow).

Bone Grafting Procedure

There are three types of bone grafting procedures performed at PM Oral Surgery. A socket graft (also known as the alveolar ridge preservation graft), a block bone graft (autogenous ramus/chin graft) and a subantral bone graft or sinus lift. Click for more information on sinus lift procedures.

A socket graft aims to prevent bone resorption at the site of an extracted tooth when a dental implant cannot immediately be placed. This socket graft fills up the space of the missing tooth with bone substitute and is set with collagen membrane and stitches.

In cases of significant jawbone loss, an autogenous ramus or block bone grafting procedure may be performed. This is where live bone from the patient's lower jaw (posterior mandible), chin (symphysis) or palate is removed and then transferred to the deficient area. The bone graft is then secured with one or two small screws and overlayed with bone substitute and collagen membrane.

It can take up to four months for the new bone to fuse to the jaw, before a dental implant or dentures can be fitted.

Bone Grafting Aftercare

For the first few days post-surgery, it is common to experience dislodged particles inside the mouth. While this is normal, there are some aftercare instructions to abide by to foster an excellent graft result and speedy recovery.

  • Avoid touching the wound or applying pressure with your tongue or fingers
  • Avoid chewing on the graft site
  • Do not smoke for a minimum of two weeks post-surgery
  • Avoid alcoholic beverages in the first week post-surgery
  • Gently rinse with warm salt water ((1/2 a teaspoon of salt in a glass of warm water) at least 4 to 5 times a day immediately following surgery.
  • Follow the oral surgeon's instructions should a medical oral rinse by prescribed
  • Continue with an oral hygiene routine (gentle brushing twice daily with a soft-bristled tooth brush and flossing once daily

Be mindful to avoid disturbing the graft area and commit to maintaining a healthy oral hygiene routine to promote faster healing.
