Jaw Bone Loss and Deterioration
A weakening of the jaw bone can occur when an adult tooth is removed without a replacement. The jaw bone usually ‘senses’ real teeth, through stimulation from chewing, biting – when a tooth is missing, then the jaw bone will no longer sense a tooth’s presence. The lack of sensing is received by the brain and interpreted as no longer necessary, so the jaw bone will begin to disintegrate and become absorbed back into the body. This type of deterioration can take place as early as 18 months after the initial extraction, but can also occur throughout the remainder of their lifetime.
Extractions on the upper portion of the jaw can also affect the sinus cavity of the patient. This could have lasting effects on the air pressure and the resorption on the bone in the affected area. Dr. El Deeb can perform a sinus lift that can treat the hyperneumatized sinuses.
The other biggest cause of jawbone deterioration is periodontal disease. It can affect the gums, alveolar bone, ligaments and cementum. Plaque makes up for the most common cause of periodontal disease and both gingivitis and periodontitis (the two main categories of periodontal diseases) can play a part in jaw bone deterioration. Gingivitis is caused by plaque. If gingivitis were to spread to become periodontitis, the gums around the tooth and holds it in place will deteriorate. This can lead to a loss or loosening of teeth, and as a result – jaw bone deterioration.
If a patient has experienced a knocked-out tooth or a broken or chipped tooth that is below the gum line, the stimulation to the jaw bone will stop and deterioration will occur. Depending on how long ago the accident or injury occurred, bone grafting will be necessary to treat the loss of jaw bone.
Dentures that are not anchored into the jaw bone can also have similar effects. If the body does not detect motion, pressure or other stimuli from a tooth, the natural response is to resorb back into the body. Some bridge work and dentures are placed directly on the gum line, and no not send stimulus so the alveolar bone. In fact, the bone loss on the jaw may be so great, that the original dentures may not properly fit anymore.
Dr. El Deeb can restore bone growth and function with a bone graft procedure.
For extreme cases of misaligned teeth, there may be instances where opposing teeth do not touch. The corresponding jaw bone then will lack the stimulus necessary to maintain its shape and deterioration may occur. Grinding, TMJ and general lack of treatment can also cause this loss to occur.
Osteomyelitis is an infection of the jaw bone and bone marrow. Without antibiotics or treatment, it can lead to inflammation and a reduced flow of blow supply to the jaw bone. Dr. El Deeb may be required to perform a bone graft in a case of Osteomyelitis.
Facial deformities, after effects from facial tumors or general deficiencies of the sinus, are also common occurrences. Tumors generally spread to the jaw if they are malignant. Dr. El Deeb would have to make an assessment on a case by case basis as to the treatment, but it would typically require reconstructive bone grafting procedures.
