Bone grafting - Lapointe dental centres

A bone transplant is an intervention that is sometime necessary when the fitting of one or more dental implants is considered. To ensure its stability, the site of the future implant requires a thickness of bone of at least 6 millimetres. Following a tooth extraction, the lack of bone stimulation may bring about a resorption that often results in insufficient bone thickness. At times, the maxillary sinus located just above the upper molar roots hang down so low that the placement of the implant is impossible unless the width and height of the bone are corrected. In such a case, the sinus elevation and bone graft will be used. The source of the graft may vary. It can be taken from the patient or another individual of the same species or even another species (very often of bovine origin). In most cases, the intervention takes place under local anaesthesia. An incision is made, providing access to the site of the future implant. Once the soft tissue is moved back, access will be created in the bone, allowing the elevation of the sinus and the installation of the bone graft. Once the bone is well compressed, the bone window will shut itself up and the soft tissue will be closed by means of a few stitches. In the case of a bone graft requiring no sinus elevation, it may be decided to screw in bone plates on the side of the jaw. After some time, the graft will bind itself with the bone tissue already in place and will form a bone plate sufficiently strong to allow the addition of the implant. A pharmacological protocol adapted to this type of intervention reduces postoperative discomfort.
