Bone is vital in the success of an implant; whenever a tooth is lost or extracted, a considerable amount of the bone that once surrounded the root portion may disappear. The rate and volume of bone lost varies from person to person but the most rapid amount of loss usually takes place in the first few months following the extraction. This is described as 'bone resorption'.
Don't worry if you haven't got enough of it or it is poor quality bone; at Gentle Dental Care we have the answers. We will use our diagnostic x-rays and 3D scan to determine if a bone graft is required. We are able to offer Onlay grafting or placement of synthetic material and tissue regeneration procedures to enable treatment with dental implants.
Bone volume to accommodate dental implants is an important consideration when planning implant treatment. Any deficiencies in jaw bone structure can be resolved using a number of bone augmentation techniques to either facilitate the placement of an implant, or to improve the aesthetic outcome of implant treatment by improving the contour of the supporting structures.
This is the most straightforward grafting procedure, often called "guided bone regeneration". The bone graft material is sourced from specially selected cattle and the patient does not require additional procedures to use their own bone. Bio-Oss™ has been used successfully for over 15 years and is used in specialist centres worldwide. To stabilise the Bio-Oss™ graft material a resorbable (dissolving) collagen membrane is sometimes required.
Bio-Oss is a safe, effective bone graft material from specially processed bovine sources. Under the electron microscope, Bio-Oss looks very similar to human bone. Because of its similarity to human bone, Bio-Oss is highly successful in helping new bone to form. In many cases using Bio-Oss eliminates the need for additional surgery to obtain your own bone to use as grafting material.
Because Bio-Oss is so similar to human bone, it is readily accepted by our defence mechanisms as a 'friendly' graft and is therefore not rejected. Bio-Oss acts as a framework onto which bone forming cells and blood vessels migrate. As these cells and blood vessels travel along the Bio-Oss framework, healthy new bone is formed and the defect is repaired.
Since Bio-Oss is highly purified bone, allergic reactions are highly unlikely. Every batch of Bio-Oss goes through highly controlled processing and sterilization procedures which remove impurities efficiently. At the end of these procedures, every batch of Bio-Oss must pass rigorous tests for purity and sterility, assuring the high safety standards of the materials.
Bio-Oss, because of its similarity to human bone, is highly successful in supporting new bone growth. Although new bone will begin to form within the first few months after grafting, the bone maturation process can take considerably longer. Your surgeon will be able to advise you as to how this may affect your treatment.
Bio-Gide is a thin resorbable membrane made from natural fibre material, collagen. Often when a bone graft is needed, Bio-Gide is placed directly over the grafted material. Bio-Gide encourages new bone to form and also prevents the growth of scar tissue into the grafted site.
In the back of the upper jaw the sinuses often occupy a large amount of space, leaving insufficient bone height for the placement of dental implants. Sinuses are large spaces in the bone and they have a thin lining. To create bone the sinus lining can be lifted and a bone graft (usually Bio-Oss™) can be placed in the floor under the sinus lining and allowed to heal.
This method of creating bone prior to implant placement is very predictable. On some occasions the sinus lift procedure and installation of the dental implants can even be carried out as a single procedure for the patient, so only one operation is required.
Your surgeon will advise you on the merits and risks of sinus lift procedures in your particular situation.
This procedure involves using the patient's own bone. This bone is considered to be the 'gold standard' in grafting procedures because the bone will have better healing properties and acceptance by the body.
In many instances, bone can be harvested and collected prior to or during implant bed preparation and re-used to repair any bone defect around the implant. This technique is particularly useful in managing some challenging cases which can otherwise be very difficult to treat and is much less traumatic for the patients.
On other occasions, if more bone volume is required, it involves using bone from another part of the patient's mouth, mostly from back of the lower jaw. This harvested bone block will be fixed to the site of the defect and it needs to be left to heal up for at least four months before placing the implant. The implant will take a further three months to integrate to the new bone. As a general rule, the augmented site using patient's own bone will have a shorter healing period compared to a graft using Bio-Oss™.
