Jawbone necrosis
Jawbone necrosis refers to a dead jawbone. Causes can be chronic inflammation, radiation (in connection with cancer treatment) or medication (especially chemotherapeutic agents, or cortisone). The most common are drug-induced jawbone necrosis.
A clinical feature is, for example, a small piece of exposed bone in the mouth. Symptoms may include jaw pain, bad breath, sensation in the lower lip, or other pain in the oral cavity. The augmentation of the jaw bone with suitable materials creates the conditions for subsequent implantation. After healing, the prognosis for further dental measures is good.
Summary
The prerequisite for placing jawbone implants is the presence of sufficient bone substance. If this is not the case, bone augmentation can be used to remedy the situation.The materials used for bone augmentation are either the body’s own bone or bone substitutes of animal, plant or synthetic origin. In the maxillary sinus area, a lifting of the maxillary sinus floor (sinus lift) creates sufficient jaw bone for an implantation. The implantation of jaw bone can be done either simultaneously or after healing.
