Grafting in Oral and Maxillofacial Reconstruction
BONE GRAFTING can be used to increase the width of a ridge, therefore allowing insertion of dental implants. This is particularly relevant in a person who has been edentulous long term in the lower jaw.
If you have had a cyst/tumour removed or had a chronic infection from a tooth this will also result in inadequate bone for placement of dental implants. Again the latest bone grafting techniques will overcome this and recreate adequate bone for the placement of the implants.
Impacted wisdom teeth can cause bone loss in the region of the distal (back) surface of the tooth in front, resulting in periodontal (gum) disease, or sensitivity of the back surface of the tooth. Bone grafting at the time of removal of the impacted wisdom teeth may prevent potential symptoms.
Many different types of bone grafting exist. Your surgeon will be able to offer a range of options appropriate to your individual requirements.
Bovine bone and porcine collagen are used in these procedures, as is your own bone, often from a chin graft which is more comfortable post surgery for you than the traditional bone graft site of the hip bone or rib bone.
Different objectives and outcomes eventuate from either type of bone grafts. Usually the surgeon will be able to provide examples of bone graft procedures that have been used on other people with exactly the same clinical requirements you have.

Bone Grafting prior to Implants
Often people decide to have an implant a long time after tooth loss. Minor bone grafting is used to enhance the dento-alveolus for later implant surgery. Overall it aims to provide for ideal dento-alveolar shape, to provide support for overlying gums, and to provide a bed for implanted titanium hardware.
General Bone Grafting to rebuild the Dento-Alveolar Form
The dento-alveolus becomes lost for a number of reasons, but often it is due to the process of tooth removal, or because of long term resorption that occurs after tooth removal. A number of techniques exist for rebuilding the dento-alveolus, but which are almost all based on graft harvest from another part of the body.
Bone Grafting and Wisdom Teeth Surgery
Impacted and abnormally located wisdom teeth often result in resorption of the alveolar bone behind the forward second molar leading to late development of periodontal problems with these teeth. Removal of a wisdom tooth can relieve the impactions or symptoms of impaction, but can cause the development of a large bone crater which leads to exposure and sensitivity of the root surface of the forward molar. Bone grafting performed at the time of "at-risk" wisdom teeth, can significantly reduce the risk of periodontal disease in affected second molar teeth.
Sinus Lift procedure prior to Implant Placement
The maxillary sinuses are air filled spaces in the cheek or zygomatic regions of the facial skeleton, and normally lie above the upper back teeth. The bone that exists around and above roots of the upper posterior teeth and below the floor of the maxillary sinuses is often very thin, and with tooth loss becomes very short in height. Sinus lift bone grafts are an effective means of preparing deep bone beds for dental implant placement.
Major Reconstructive Bone Grafting
With frank tumour or cystic disease, often the only treatment is to take away affected jaw bone, in which the tumour process is wholly embedded. Whilst maximally curative for recurrent disease, the treatment can lead to significant deformity and loss of anatomical form. Bone grafting performed at the time of ablative surgery aims to maximally preserve anatomical form, and to allow for normal dental treatment processes that can later replace teeth through dental implants.
Complimentary Attached Gingival (Gum) Grafting
With bone loss, soft tissues often shrink and become thinner. Bone grafting may lead to loss of vestibular depth, with impingement of non-attached gingivae to areas where dentures or implants require the durability of attached gingivae. Techniques exist for predictable mucosal grafts that can enhance attached gingivae in emerging areas of implants or around teeth affected by excessive tooth brushing or otherwise unstable gum form.
Maxillofacial Trauma Surgery
Surgery to correct for trauma to teeth, jaws and facial bones
Our surgeons at Profilo are able to provide the full range of treatment modalities for facial trauma through our rooms at Honeysuckle, or through our private hospital affiliates (Warners Bay Private Hospital, Toronto Private Hospital and Newcastle Private).
In particular, our doctors are available to privately assess patients for oral and maxillofacial trauma outside of normal work hours.
For most forms of trauma, it is vital to have an immediate assessment, and to arrange for a definitive treatment pathway as soon as possible after the accident. By operating out of private hospitals we are able to accommodate most forms of specific facial bony trauma, and without lengthy public hospital waiting periods for initial emergency management.
