聚焦发育，而非聚焦症状
治疗从牙齿不齐的根本原因入手 —— 习惯、呼吸、颌骨生长 —— 而不是日后再用托槽掩盖问题。
儿童矫正 · 3–12 岁
东京 Myobrace —— 针对儿童的早期矫正治疗
聚焦发育的治疗方式，从根本原因入手解决牙齿不齐：口腔习惯、呼吸方式与颌骨生长。以 Myobrace 为主要系统；在适合的情况下采用 Invisalign First 或 Smartee Aligner。
Noticing something about your child's teeth or bite?
Worried your child's teeth or bite aren't developing quite right?
Crowding, a gap, an overbite, or a habit like mouth-breathing can be hard to read as a parent — and it is natural to wonder whether to wait or to act now.
Early, growth-guided orthodontics can gently steer how the jaw and teeth develop, often easing the need for harder treatment later. Below: how we assess and guide your child's development in Tokyo, the cost in writing, and what to expect — explained to you and your child in English.
About
什么是 Myobrace 与早期矫正治疗？
Myobrace 是一系列可摘式口内矫治器，旨在解决生长发育期儿童牙齿不齐的根本原因 —— 即不良口腔习惯、口呼吸与舌位异常。
与等到恒牙萌出后再用托槽或隐形矫治器治疗症状不同，早期矫正在儿童仍处于生长阶段时，引导自然颌骨发育并矫正不良习惯。
在罗丹齿科，Myobrace 系统是首选方案。Invisalign First 与 Smartee Aligner 在适合采用透明矫治技术的病例中，作为替代或互补系统使用。我们刻意不将传统扩弓板（拡大床）纳入诊疗方案 —— 我们的重点是通过良好习惯引导自然发育。

The Pureteth programme
Myofunctional training for growing children
Pureteth is a myofunctional training programme for children. Using a soft, removable trainer (Myobrace®) together with simple daily exercises, it works on the oral habits that can interfere with natural development — mouth breathing, low tongue posture, and incorrect swallowing — during the years a child is still growing.
Rather than waiting for all the permanent teeth to come through and then moving them, Pureteth aims to guide healthy jaw and facial growth early. Where habits are corrected in good time, this can reduce the likelihood of needing braces or extractions later — though every child is different, and some still benefit from further orthodontics in the teenage years.
A nationwide programme
Pureteth has been used in more than 2,000 cases across Japan, making it one of the country's more widely-used myofunctional training programmes.
Supervised by experienced clinicians
Treatment is supervised by dentists and staff experienced in myofunctional therapy, so your child is guided and supported at every stage.
Online consultations available
Busy families can begin with a remote consultation in English before visiting the clinic in person.
Early signs
Does your child show any of these signs?
Oral and facial development is strongly shaped by how the muscles of the tongue, lips and cheeks work together. Allergies, mouth breathing, and habits such as thumb-sucking can affect that balance and, in turn, the way the jaw and teeth develop. Many children begin to show signs from an early age — and the earlier they are noticed, the more options there usually are.
- Mouth breathing
- Thumb or finger sucking
- Low tongue posture / tongue thrusting
- Snoring or restless sleep
- Crowded or crooked teeth
- Difficulty closing the lips at rest
- Incorrect swallowing pattern
- Speech difficulties
- Grinding teeth
If habits like these continue, they may affect how the jaw develops and increase the likelihood of misalignment. A consultation can help you understand what — if anything — is worth acting on for your child.
Understanding malocclusion
Common types of misaligned teeth
There are many forms of malocclusion. These are some of the most common bite and alignment patterns seen in children:
Crowding
Teeth are crowded, overlapping, or rotated because there isn't enough room in the jaw. This is the most common pattern, often linked to a jaw that is narrower than the teeth need.
Overjet
The upper front teeth sit well ahead of the lower teeth (often described as 'protruding' front teeth). It can relate to jaw growth, genetics, or habits such as lip-biting or thumb-sucking.
Underbite (reverse bite)
The lower front teeth sit in front of the upper front teeth. It is often related to jaw growth patterns, and is one of the patterns where an earlier assessment is particularly worthwhile.
Open bite
The front teeth don't meet when the back teeth are closed together. It is frequently associated with tongue posture, thumb-sucking, or mouth breathing.
Crossbite
Some upper teeth bite inside the lower teeth instead of outside them. Left unaddressed, it can affect how evenly the jaw grows.
Deep bite
The upper front teeth cover too much of the lower front teeth when biting. Over time this can affect tooth wear and jaw comfort.
Why early intervention
Reasons families choose to start early
Works with natural growth
Starting during the growth phase means treatment can work with a child's development rather than against it, helping guide the jaw in a favourable direction.
No fixed wires or brackets
Pureteth uses a removable trainer rather than fixed braces, so children can eat, brush, and play sport as usual.
Gentle on daily life
Because the trainer is removable, it's easier to keep up good oral hygiene and fit treatment around school and family routines.
Addresses underlying habits
Myofunctional training works on the muscle habits — breathing, tongue posture, swallowing — that can sit behind misalignment, not only the position of the teeth.
May reduce later treatment
Guiding growth and correcting habits early can reduce the likelihood — though not always remove the need — of braces or extractions later.
Manageable for busy families
Daytime wear is only a short period each day plus overnight, which keeps the routine realistic to sustain over time.
The daily routine
What the Pureteth programme involves
The programme fits into everyday life through a simple, repeatable rhythm of wear and short daily exercises, with a monthly check-in at the clinic.
Night-time wear
Your child wears the Myobrace® trainer while sleeping, supporting the jaw and teeth through the night-time hours.
1–2 hours of daytime wear
A short period of daytime wear — after school or during quiet time — reinforces the night-time work and helps the routine settle in.
~10 minutes of daily activities
Simple daily exercises ('activities') retrain the muscles of the tongue, lips and cheeks and encourage nose breathing, in a way children can enjoy.
Monthly clinic visits
Once a month, the dentist checks progress, adjusts the trainer if needed, and updates the activities — so families always know how treatment is going.

Risks & considerations
风险与注意事项
Every dental procedure carries some risk. The points below outline what most patients can expect. Your individual risk profile is discussed in detail during your consultation, and any case-specific considerations are noted in writing as part of your treatment plan.
- 依从性至关重要 —— 必须按照建议时长每日佩戴训练器，并持续完成训练动作。
- 治疗周期取决于儿童的生长模式；年龄较小且习惯仍较活跃的儿童见效更快。
- 并非所有错颌畸形都能仅通过早期矫正解决；部分病例在青少年阶段仍需托槽或隐形矫治。
- 家长的支持必不可少 —— 尤其是年龄较小的孩子，需要鼓励才能坚持日常训练。
Not suitable for
- 存在严重骨性差异、成年后可能需要手术干预的儿童（将在咨询时评估）。
- 孩子或家庭无法承诺坚持每日佩戴与训练计划的情况。
Concerns addressed

Stay length depends on the treatment — see the section above for the typical timeline. Your final itinerary is confirmed after the online consultation so flights and accommodation can be planned with confidence.
Common questions
Frequently asked
我的孩子应在几岁开始 Myobrace？
+
Myobrace 最早可从 3 岁开始，多数儿童在 5 至 9 岁之间起始，此时不良习惯与发育中的牙列更容易受到引导。最佳起始年龄将在初次评估时确认。
Myobrace 治疗需要多长时间？
+
活跃治疗期通常持续 12–24 个月，具体取决于孩子的年龄、生长模式与佩戴依从性。之后进入保持期以稳定治疗效果。
Myobrace 是否能取代传统托槽？
+
在部分病例中可以 —— 成功完成 Myobrace 的儿童通常在青少年时期几乎不需要或完全不需要进一步矫正。在其他情况下，Myobrace 也能打下良好基础，简化日后的托槽或隐形矫治。
为什么罗丹不使用扩弓板（拡大床）？
+
我们的方案优先通过习惯矫正引导自然颌骨发育。扩弓板通过机械力扩展腭部，确实能起到一定作用，但并未解决导致错颌的根本习惯问题。我们更专注于习惯与发育本身。
孩子佩戴 Myobrace 时还能参加运动吗？
+
可以。Myobrace 训练器仅在白天佩戴 1–2 小时（通常是在家中做安静活动时）加整夜佩戴。运动、进食与刷牙时取下即可。
如果孩子拒绝佩戴训练器怎么办？
+
依从性是成功的关键因素。我们会与家长共同制定适合不同年龄阶段的引导策略，并循序渐进地升级训练器，让孩子逐步舒适适应。
做 Myobrace 是否必须住在东京？
+
每月至每两个月一次的现场复诊最为理想。国际家庭通常会与当地正畸医师协调进行常规复查，并定期到罗丹完成关键阶段的评估。
Invisalign First 与 Myobrace 有何不同？
+
Invisalign First 是一种针对生长期儿童的透明矫治系统。对于更适合透明矫治技术的病例，它可与 Myobrace 互补或替代。具体选择将在咨询时根据个案情况决定。
