Do you have missing teeth? If so, the passage of time will result in the jawbone associated with those teeth being atrophied or reabsorbed. These type of bone issues can create significant challenges for patients desiring dental implants.
Thanks to advanced technology, bone can be grown where needed. Because of this ability, implants that are the correct length and width can be placed. Craig Conrow DDS MS FACP has given several patients a fully restored aesthetic appearance and oral functionality.
The inadequate bone structure resulting from tooth extractions, injuries or gum disease can be repaired with bone grafts. The new bone is either obtained from a tissue bank or taken from your own tibia, hip or jaw. In the upper posterior jaw, sinus bone grafts can also be performed. If needed, special membranes that dissolve under the gum can encourage regeneration of the bone and protect the bone graft. These instances are referred to as guided tissue regeneration or bone generation.
Defects of the jaws are usually addressed with major bone grafts. Defects of this nature can be the result of traumatic injuries, congenital defects or tumor surgical procedures. Larger problems are repaired with the use of the patient’s own bone. Depending on the size of the problem, the bone could be harvested from a variety of sites. Common donor sites include the hip, lateral knee and skull. Procedures of this nature normally take place in the OR and result in a hospital stay.
Located behind your cheeks, above the upper teeth are your maxillary sinuses. The sinus cavities are similar to empty rooms that have nothing in them. Some natural teeth roots extend up into the maxillary sinuses, and when those upper teeth are removed only a thin layer of bone remains to separate the mouth and the maxillary sinus from one another. Dental implants need bone to be held in place. It is virtually impossible to place dental implants in the bone when the sinus wall is thin.
A sinus graft is a procedure that enables many patients to have dental implants rather than be forced to wear loose fitting dentures. When there is enough bone between the bottom of the sinus and the upper jaw ridge to ensure the implant is properly stabilized, sinus augmentations can often be performed as a single procedure with the placement of the implant.
