Will Orthodontic Treatment for Deep Bite Make My Chin More Protruded?

After orthodontic treatment for deep bite, I hope my chin does not become more pronounced?

I am currently undergoing orthodontic treatment for deep bite.
My doctor’s treatment plan involves placing four bone screws near the upper and lower wisdom teeth to pull the upper teeth back while simultaneously pulling the lower teeth forward.
I would like to know if this will cause my jaw to shift and become more prominent than it already is, as I already have a slight overbite and am concerned that the treatment may worsen it, making my appearance less favorable.
I would like to ask the doctor a few questions: (1) Can the use of bone screws allow the entire row of teeth to move forward or backward? (2) Is there a method to use the chin as a pivot point (keeping it stationary) while moving the lower teeth forward? (3) Are there other treatment options available that could help minimize the prominence of my chin? Thank you for taking the time to read and patiently consider my questions.
Wishing you health and happiness!

Hello, the patient's deep bite condition is caused by the protrusion of the maxilla and the retrusion of the mandible.
Therefore, what we observe externally (the protrusion of the chin you mentioned) is due to the cartilage tissue, while the bone itself does not protrude.
So there is no need to worry about it becoming more severe after correction.
The bone screws are used for anchorage, and teeth will be repositioned from within the oral cavity; these two parts need to move relative to each other.
The patient must also be patient and follow the orthodontist's instructions throughout the treatment process.
During this period, please maintain oral hygiene.
Wishing you safety and health.
Sincerely, Dr.
Huang Chih-Cheng, Director of Dentistry, Taoyuan Hospital, Ministry of Health and Welfare.

More Info

Orthodontic treatment for deep bite can indeed raise concerns about the potential for changes in facial aesthetics, particularly regarding chin prominence. Your current treatment plan, which involves the use of bone screws (also known as temporary anchorage devices or TADs) to reposition your teeth, is a common approach to address deep bites. Let's address your concerns and questions in detail.

1. Will the use of bone screws allow for the movement of the entire dental arch?
Yes, bone screws are designed to provide a stable anchor point for orthodontic forces. They can facilitate the movement of both the upper and lower teeth. In your case, the treatment aims to retract the upper teeth while simultaneously advancing the lower teeth. This dual movement can help correct the deep bite effectively. However, the extent of movement will depend on individual anatomical factors and the specific mechanics employed by your orthodontist.

2. Is it possible to use the chin as a fixed point while moving the lower teeth forward?
In orthodontics, the chin itself cannot be used as a fixed point in the same way that bone screws can. However, orthodontists can employ various techniques to minimize the impact on the chin's position. For instance, careful planning of tooth movement can help achieve a more balanced facial profile. Your orthodontist may consider using additional appliances or techniques to ensure that the lower teeth are moved forward without significantly altering the position of the chin.

3. Are there alternative treatment methods to prevent chin protrusion?
If you are concerned about exacerbating the existing chin prominence (often referred to as a "prognathic" appearance), it is essential to discuss this with your orthodontist. They may suggest alternative strategies, such as:
- Surgical options: In some cases, orthognathic surgery may be recommended to reposition the jawbones for a more harmonious facial profile. This is typically considered when dental treatment alone cannot achieve the desired results.

- Different orthodontic mechanics: Your orthodontist may explore other methods of tooth movement that could minimize the impact on your chin's appearance. This could include adjusting the force applied to the teeth or using different types of appliances.

- Comprehensive treatment planning: A thorough evaluation, including X-rays and 3D imaging, can help your orthodontist devise a treatment plan that considers both dental alignment and facial aesthetics.

It's crucial to maintain open communication with your orthodontist throughout your treatment. Share your concerns about the potential for increased chin prominence, and ask for their professional opinion on how to achieve the best possible outcome. They can provide you with a tailored treatment plan that addresses both your dental needs and aesthetic goals.

In conclusion, while orthodontic treatment for deep bite can lead to changes in facial aesthetics, careful planning and execution can help mitigate any adverse effects. Your orthodontist is your best resource for understanding how your specific treatment plan will affect your facial profile and for exploring options that align with your aesthetic preferences. Remember, patience is key in orthodontic treatment, and maintaining good oral hygiene during this process is essential for achieving optimal results.
