performed?Following tooth extraction, there follows a period of healing during which there is loss of bone from around the tooth socket.\u00a0 This takes place over a few months but continues at a slower rate over the years that follow.\u00a0 Therefore if a tooth bas been missing for a period of years, it is common to find that there is insufficient bone remaining to support an implant in its correct position and bone grafting may be required.\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0Bone defects may also occur in the jaws as a result of acute or chronic infection or following\u200b the removal of teeth that are impacted and require bone removal for their extraction.Implant Planning Before ExtractionIf implant treatment is planned for the replacement of a tooth before it is extracted, then the tooth is removed very gently in what is termed an atraumatic extraction technique thereby preserving as much bone as possible.\u00a0 Then the socket from which the tooth has been removed is generally filled with a grafting material to preserve the bony ridge.\u00a0 This process is called ridge preservation and it results in the maintenance of the bone and may prevent the need for bone grafting at the time of implant placement later after healing of the site has taken place.Should there be insufficient bone in which to place an implant, it is possible to grow additional bone following bone-grafting procedures.\u00a0 Bone grafting is a common procedure that restores the contour of the jaw-bones and encourages the growth of new bone in a defect where bone has been lost or destroyed.By replacing lost bone, implants can be placed in the most appropriate position to ensure the crown is correctly located to function against the opposing tooth.\u00a0 If implants were placed where previous bone remained, then the implant may be located both in the wrong position and at an incorrect angulation making restoration difficult or impossible.Different bone grafting techniquesThere are several different bone grafting techniques and augmentation materials that may be used. Grafting materials can be in the form of a block, granules or paste.\u00a0 All are used in entirely different techniques.\u00a0 Dr Colin Priestland will explain to you the technique that is most suitable for your treatment.What grafting materials are used here?Generally, Dr Colin Priestland uses bovine (cow-derived) bone matrix that has been de-proteinised, demineralised and sterilised.\u00a0 The products are then mixed with the patient\u2019s blood or blood products to allow a mouldable graft to be placed into a bone defect.\u00a0 This material must then be covered with a barrier membrane.A barrier or occlusive membrane is a material that prevents the defect and graft being invaded by overlying soft tissue cells.\u00a0 By the exclusion of soft tissue, the defect or graft can only be repopulated by cells native to the defect, these being the osteoblasts responsible for the manufacture of bone.The usual material used as a barrier membrane by Dr Colin Priestland is a porcine (pig-derived) collagen membrane.\u00a0 It is dissolving and disappears in time but prevents soft tissue growing into the graft site during the early stages of healing and thereby favours the formation of new bone at the site.Swiss Grafting MaterialsThe materials used in the practice are generally manufactured by Geistlich and include BioOss Collagen Block, BioOss granules, BioGide collagen membrane and Mucograft collagen matrix.\u00a0 Geistlich is a Swiss company that has been involved in the production of grafting materials for many years.\u00a0 They produce a range of bone grafting products that are used in orthopaedic surgery and oral surgery.\u00a0 These grafting products are the only bone augmentation materials accepted by the International Red Cross and that allow patients who have been treated with them to continue to be blood or organ donors.There are numerous other grafting products available made by many companies throughout the world, some that are human donor tissue, some animal derived products and others that are entirely synthetic.\u00a0 All products used in this practice are approved by the Therapeutic Good Administration and are approved for use in Australia.\u00a0 Products used in other countries, but not TGA approved, are not used at our practice.Use of patient\u2019s own bone for graftingSome bone defects are large and therefore it may be necessary to use a combination of the grafting material supplemented with bone from the patient, this being referred to as a mixed autograft.\u00a0 Bone granules may be obtained from adjacent sites within the mouth or blocks of bone may be harvested from either the chin or the back of the lower jaw.\u00a0 In extensive jaw reconstructions, bone may be harvested from ribs or from the pelvis.Small bone grafts can be completed in the chair here in the practice but more extensive grafting or multiple grafts are generally performed in the Mater Day Surgery Unit at Hyde Park under a day stay general anaesthetic.Radiological investigation before implant therapy \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 If you are to receive implant therapy, then you will have a 3D cone bean CT scan taken to allow accurate assessment of the remaining bone shape and volume.\u00a0 The cone beam scan will also identify the area where bone grafting has been performed and demonstrate that there is now sufficient bone of adequate density to support an implant.If you are being assessed for an implant prior to any grafting procedure, after a recent dental extraction for example, Dr Colin Priestland will then place an implant in the best position in the site of the missing tooth or teeth, \u201cvirtually\u201d on the computer screen and this then allows him to assess if you are going to require bone grafting to achieve the intended outcome.Pre-surgical explanations and informed consentYou will receive a thorough explanation of the procedure and the planning will help you to understand what is to be done.\u00a0 You will have the opportunity to ask any questions and receive detailed answers.\u00a0You will receive a leaflet on implants to ensure you have a thorough understanding of the treatment including the risks, benefits and potential complications.Only after all the planning has been performed and you have had the opportunity to ask questions will you be asked to sign your informed consent for the surgery.\u00a0 You will then be provided with information leaflets on post-operative care at home, medications that you should take after surgery and a prescription for those medications.For more information:\u00a0Bone Graftscontact the friendly team at NQ Surgical Dentistry today on\u00a0(07) 4725 1656 or call in to see us at\u00a0183 Kings Rd,
