3 sacadas que você precisa saber sobre a ortopedia funcional dos maxilares

Summary

The transcript discusses the importance of proper nasal breathing in children and its impact on their dental and facial development. It highlights how poor breathing can lead to maxillary atresia, excessive mandibular growth, and crossbite issues. The script emphasizes the role of the tongue in shaping the jaw and provides detailed instructions on how to use orthodontic appliances like the SM3 to correct these issues. Special attention is given to the precise measurements and adjustments required for these appliances to be effective, ensuring proper alignment and expansion of the maxilla to encourage optimal dental growth.

Takeaways

• 😀 Breathing through the nose is essential for proper facial development in children. Without it, issues like maxillary atresia can occur.
• 😀 Parents need to be convinced of the importance of nasal breathing for their child's health and development. Showing visual aids can help in this process.
• 😀 Lack of nasal breathing causes the tongue to remain low in the mouth, which leads to abnormal jaw growth and can exacerbate existing conditions.
• 😀 A large jaw combined with a lack of nasal breathing can lead to significant growth in the mandible, resulting in a transverse jaw pattern (Class III).
• 😀 For effective treatment, it's crucial for children to breathe through their noses and position their tongue on the roof of their mouth.
• 😀 Crossbites, especially anterior crossbites, can be corrected by orthodontic treatments like disjunction, but nasal breathing and tongue positioning are key.
• 😀 When designing dental appliances, it's crucial to ensure the proper fit and function. If a crossbite is present, it's important to check the alignment and effectiveness of the appliance.
• 😀 Adjustments to dental devices should be made with care, especially when using appliances like the SM3. Proper activation and fitting are necessary for success.
• 😀 The wire bar in dental appliances, such as the ondulated bar, needs to have a specific design for effectiveness. It should create discomfort in the tongue to encourage proper oral positioning.
• 😀 A poorly designed appliance with insufficient space between components (such as the bar and the tongue) will not work as effectively, and adjustments may be needed to ensure the appliance fits properly.

Q & A

Why is it important to encourage a child to breathe through their nose?

Breathing through the nose helps to prevent issues like maxillary atresia and improper jaw development. If the child breathes through their mouth, it can cause the tongue to drop, affecting jaw alignment and leading to problems like overgrowth of the mandible.

What is maxillary atresia and how is it related to breathing through the nose?

Maxillary atresia is a condition where the upper jaw fails to grow properly. It occurs when the child breathes through the mouth, causing the tongue to drop and disrupting the natural growth of the jaw, leading to issues like a narrow upper jaw and misaligned teeth.

How does the position of the tongue affect jaw development?

The tongue plays a crucial role in guiding the growth of the jaws. When the tongue is positioned properly on the roof of the mouth, it stimulates the maxilla to grow outward. If the tongue is positioned incorrectly, such as when it rests low in the mouth due to mouth breathing, it can inhibit maxillary growth and promote excessive growth of the mandible.

What happens if a child has a large mandible and improper tongue positioning?

If a child has a naturally large mandible and improper tongue positioning (like a low tongue due to mouth breathing), the mandible can grow even larger, leading to an exaggerated jaw structure. This can result in a Class 3 bite, where the lower jaw protrudes more than the upper jaw.

Why is it necessary for a child to breathe through their nose for proper orthodontic treatment?

Nasal breathing is crucial because it helps maintain proper tongue positioning, which in turn supports correct jaw development. Without this, even orthodontic treatments like expansion or disjunction may not be effective in correcting jaw misalignments.

What is the significance of the crossbite in orthodontic treatment?

A crossbite occurs when the upper teeth do not align with the lower teeth properly, either in the front or back of the mouth. This can cause problems with jaw growth and lead to issues like an imbalanced bite and improper dental development, requiring orthodontic intervention.

What should an orthodontist consider when a patient has a significant anterior crossbite?

For a patient with a significant anterior crossbite, it is important to evaluate the growth of the maxilla and mandible. A crossbite may indicate a lack of maxillary development or excess mandibular growth, which may need to be addressed with specific orthodontic appliances or treatments.

How does the use of a specific orthodontic appliance, like the SN3 appliance, aid in crossbite correction?

The SN3 appliance is designed to correct crossbite by applying controlled pressure on the teeth and jaw. It helps reposition the teeth and promotes better alignment, and when used consistently, it can provide significant improvement in just a few months.

What is the importance of the 'ondulated bar' in orthodontic appliances?

The 'ondulated bar' is a key component in some orthodontic appliances. It helps ensure the tongue remains in contact with the roof of the mouth, providing the necessary discomfort to stimulate proper maxillary expansion. The design and spacing of this bar are crucial for the appliance to work effectively.

Why must the dimensions of the ondulated bar be precise for the appliance to work effectively?

The dimensions of the ondulated bar must be precise because the bar’s height and spacing directly impact how the tongue interacts with it. If the spacing is too wide or too narrow, or the height is incorrect, it may not create the necessary discomfort to stimulate the desired changes in jaw alignment and growth.
