Temporomandibular joint reduction surgery


If I underwent orthodontic treatment 3.4 years ago and am now experiencing issues with my temporomandibular joint (TMJ) (with milder symptoms at the time), will I need to undergo orthodontic treatment again after undergoing TMJ reduction surgery, given that my occlusion is currently normal?

Hello: It is recommended to inform the physician before surgery about any previous orthodontic treatment.
If necessary, minor adjustments to the position of the teeth may still be performed postoperatively.
You may ask the oral surgeon whether a referral to the orthodontist is needed for a discussion of the treatment plan.

After undergoing TMJ (temporomandibular joint) surgery, the necessity for orthodontic treatment can vary based on individual circumstances. In your case, since you had orthodontic treatment 3-4 years ago and your occlusion (bite) is currently normal, the decision to pursue further orthodontics after TMJ surgery will depend on several factors.

Firstly, it’s essential to understand the purpose of TMJ surgery. This procedure is typically performed to alleviate pain, improve jaw function, and correct any structural issues within the joint. If the surgery successfully resolves your TMJ symptoms and your bite remains stable post-surgery, orthodontic treatment may not be necessary. However, if the surgery alters your bite or if there are residual alignment issues, orthodontics might be recommended to ensure optimal function and aesthetics.

Secondly, the relationship between your teeth and jaw position is crucial. Even if your occlusion appears normal, subtle changes in jaw alignment post-surgery can lead to long-term issues. For instance, if the surgery results in a change in the position of your jaw, it might affect how your teeth come together, potentially leading to uneven wear, discomfort, or further TMJ issues. Therefore, a thorough evaluation by an orthodontist or your oral surgeon is essential to determine if any adjustments are needed.

Additionally, it’s worth considering that TMJ disorders can sometimes be linked to dental alignment issues. If your previous orthodontic treatment did not fully address underlying problems that contributed to your TMJ issues, you may still benefit from orthodontic intervention. An orthodontist can assess your current dental alignment and jaw relationship to identify any discrepancies that could be contributing to your TMJ symptoms.

Moreover, the timing of orthodontic treatment is also a factor. If you undergo orthodontics too soon after TMJ surgery, it may interfere with the healing process. It’s generally advisable to wait until you have fully recovered from surgery and your jaw has stabilized before considering any orthodontic adjustments.

In conclusion, whether you need orthodontics after TMJ surgery depends on the outcome of your surgery, the stability of your occlusion, and any changes in your jaw alignment. A collaborative approach involving your oral surgeon and an orthodontist will provide the best guidance tailored to your specific situation. They can perform a comprehensive evaluation, including imaging studies if necessary, to determine the best course of action. If orthodontic treatment is deemed beneficial, it can help ensure that your bite remains functional and comfortable, ultimately contributing to your overall oral health and quality of life.
