Issues with the mandible?


Hello, doctor.
I would like to ask...
um...
actually, I'm not sure what that area is called, but from the side view, the distance from my chin to my neck seems shorter than others.
Since everyone can move their mandible forward to create an overbite, I noticed that when I pushed my mandible forward, it seemed to be positioned a bit further back.
I consulted an orthodontist who mentioned that I have a malocclusion issue.
So, I would like to know if orthodontic treatment can help move my entire mandible forward a bit.
Additionally, would using a commercially available dual-layer sports mouthguard as a bite plate help if I bite down on it frequently? Thank you, doctor.

Dear Xiao Yu,
Based on your description, you have a Class II malocclusion, characterized by a smaller and retruded mandible with deep overbite.
During puberty (around high school age), it may have been possible to use an activator to promote forward growth of the mandible.
However, since you are now 25 years old, the only option for correction is through orthognathic surgery.
Using a functional appliance can only temporarily advance the mandible and does not provide a long-term solution.
Wishing you health and safety.
Sincerely,
Dr.

When it comes to jawbone issues and misalignment, orthodontics can indeed play a significant role in addressing these concerns. Your description suggests that you may be experiencing a form of malocclusion, which is a misalignment of the teeth and jaws. This can lead to various functional and aesthetic issues, including difficulties in chewing, speaking, and even discomfort in the jaw joint.


Understanding Jawbone and Orthodontics
1. Jawbone Structure and Function: The jawbone, particularly the mandible (lower jaw), plays a crucial role in facial aesthetics and function. If the mandible is positioned too far back, it can create a "weak chin" appearance and may lead to an overbite or other alignment issues. This misalignment can also affect the temporomandibular joint (TMJ), leading to pain and dysfunction.

2. Orthodontic Treatment: Orthodontics primarily focuses on correcting misaligned teeth and jaws. In your case, if your orthodontist has identified a malocclusion, they may recommend braces or clear aligners to gradually shift your teeth into a more favorable position. This process can also help in repositioning the jaw if necessary. In some cases, if the misalignment is severe, surgical intervention may be required in conjunction with orthodontic treatment to achieve optimal results.

3. Functional Appliances: In addition to traditional braces, orthodontists may use functional appliances designed to modify jaw growth and positioning. These devices can help in guiding the lower jaw forward, improving both function and aesthetics. It's essential to have a thorough evaluation by an orthodontist who can determine the best course of action based on your specific needs.


The Role of Mouthguards
Regarding your question about using a dual-layer sports mouthguard as a bite plate, it’s important to understand its limitations:
1. Temporary Relief: While a mouthguard can provide some temporary relief by cushioning the teeth and reducing the impact of grinding or clenching, it is not a substitute for professional orthodontic treatment. Mouthguards are primarily designed to protect teeth during physical activities and may not effectively address underlying alignment issues.

2. Potential Risks: Using a mouthguard without professional guidance may lead to further misalignment or discomfort. If the guard alters your bite or encourages improper jaw positioning, it could exacerbate existing issues rather than alleviate them.

3. Consultation with Professionals: It’s crucial to consult with an orthodontist or a dental professional before using any over-the-counter dental devices. They can provide tailored advice and ensure that any appliance used will not interfere with your treatment plan.


Conclusion
In summary, orthodontics can significantly help with jawbone misalignment and related issues. If your goal is to reposition your lower jaw, working closely with an orthodontist is essential. They can develop a comprehensive treatment plan that may include braces, functional appliances, or even surgical options if necessary. While using a mouthguard may provide some temporary comfort, it should not replace professional treatment. Always consult with a qualified dental professional to ensure that you are taking the right steps toward achieving your dental health goals.
