For the classification of temporomandibular disorders, the third category is bone wear, which can be combined in any other category of patients, usually middle-aged and elderly patients. If unfortunately you are not a middle-aged or elderly patient lacking and have this problem, then my only advice is to hurry to learn rest position and maintain good cervical posture, replace the missing teeth, avoid unilateral chewing and try not to eat hard objects. However, many young patients, especially female patients, are very much entangled in this problem, and the fear of bone wear and face deformation makes them go around to doctors, and the internet is also full of all kinds of speculations and fears that the face deformation will be more serious in the future, in fact, face deformation will occur when the articular disc is displaced, at this time it is not the bone wear, but the vertical height of one side without the articular disc that makes the mandible In this case, it is not the wear and tear of the bone, but the lack of vertical height of the articular disc on one side that causes the mandible to be different in length, or the left and right mandibles are not in the same plane and rotate from side to side, usually to the affected side, causing the face to change shape. The change of facial shape after the displacement of the articular disc is immediate and relatively stable. In some cases, the condylar bone is resorbed and the length of the condyle becomes significantly shorter, which is more serious and does not exclude the need for surgery. In many adolescents, some patients have condylar resorption, which should be monitored periodically, but it will reach an equilibrium and will not continue endlessly. We have seen several cases of severe condylar bone wear without displacement of the articular disc. This joint is very capable of repair, and a good resting position can increase the chances of the joint repairing itself. However, if you clench your teeth, chew hard objects frequently, or even grind your teeth at night for a long time, you will put pressure on the joint for a long time and cause bone wear, resulting in more serious deformation. So again, it is important to emphasize the resting position and maintain the overall cervical posture. Some patients complain that their muscles have atrophied, inflammation in the joints will make the muscles suffer atrophy, and the affected side of the joint will be used less after the disease, and the muscles will also atrophy, but as long as the joints are used slowly and correctly in the future, the muscles will still be slowly strong and plump. You should also divert your attention from thinking about this disease and your face. The face is not completely symmetrical, and how many people will look at you directly from the front, and when you have the disease, you can only actively treat and adapt to the physical changes brought about by the disease. When bone changes are combined with pain, it is necessary to rely on anti-inflammatory and analgesic drugs to improve inflammation and eliminate pain. Bone changes are not scary, pain is the problem we need to address.
