Bone grafting is an advanced technique which is commonly used as part of the preparations for a dental implant treatment. Dental implants need healthy jawbone structure as a base where they can be attached to. However, if the jawbone is thin or has deteriorated, it can be difficult or nearly impossible to successfully place the implants. Bone grafting improves the structure of the jawbone to aid the successful placement of dental implants. This technique involves the additional of bone grafting material to add height and volume to the jawbone.
There are different bone grafting options that can be done, depending on the patient’s specific case.
Onlay Grafting – this is a grafting type that involves the placement of grafting material either to the side of the top of the patient’s existing jawbone structure. This technique is usually done in cases when the patient’s jawbone has deteriorated due to long-term tooth loss.
Block Grafting – this technique involves the use of whole blocks of bone, which can be sourced from the patient’s own body, or through a tissue bank. The block of bone is specifically measured to fit the jawbone area, and is held in place with bone screws which will be removed after the bone has successfully integrated with the surrounding tissue.
Particulate Grafting – the material for this technique is made up of cortical and cancellous bone, which has the advantage of a quicker integration and regeneration time. This results to a shortened healing period, making it possible for the dental implants to be placed into the jawbone after a shorter period of time.
Interpositional Graft – this highly-advanced method involves sectioning the patient’s own bone, and then moving it to the area of the jawbone where it is needed for the implant treatment.
