Patient: In May last year, I had two porcelain teeth, one of them killed the nerve, the other did not, in December, the examination found a bit of alveolar bone resorption, so remove the original porcelain teeth in the hospital after the root canal treatment, but I found that during that period, the alveolar bone resorption is very fast, when the porcelain teeth before redo I can clearly see the bone above one tooth, the other tooth is very concave, two teeth above the concave are very Although now I have redone the porcelain teeth, but the effect is still not very good Is there any way to repair the bone resorption? Please guide you, if there is no such technology in China, where can, looking forward to your valuable advice! Doctor: Generally speaking, the resorption of alveolar bone will not cause facial collapse deformity, only when the maxillary cusp teeth (tiger teeth) after extraction, may cause a certain degree of facial collapse, mainly slightly old feeling, but most can be corrected by dental implants. For your age and dental situation, alveolar bone resorption should be a vertical height reduction, will not affect the face, can be restored to the original state through dental implants (including porcelain dental repair), alveolar bone resorption after the height of the reduction, can also be made up through dentures. As for the porcelain teeth above the concave is related to the counterparts of the tooth surface, not artificial phenomenon, is to establish a normal bite relationship. If you feel that after wearing porcelain teeth still feel the face is not full, or uncomfortable, can be solved by redoing porcelain teeth, and properly increase the thickness of porcelain teeth outside to support the face. These problems can be solved domestically. In addition, each person’s face is actually not 100% symmetrical, but usually few people to pay attention to, once there is some doubt, it will produce the more you look at the feeling of asymmetry, so you also have to rule out the psychological illusion, you can let friends or family around to see if there is really a significant change from the previous.
