Severe mandibular protrusion (underbite, Class III malocclusion)<\/strong><\/em><\/p>\n\n\n\n<p><br>This is a case where the lower jaw protrudes further than the upper jaw, and it is one of the most time\u2011sensitive conditions in pediatric orthodontics.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Optimal timing: ages 7\u20138<\/li>\n\n\n\n<li>Reason: Only at this age can the growth direction of the jaw be modified<\/li>\n\n\n\n<li>If the timing is missed: Many cases require considering jaw surgery in adulthood<\/li>\n<\/ul>\n\n\n\n<p><br>Children with an underbite tend to have strong forward jaw growth, so appliances are used to guide the growth direction downward. \u00a0<\/p>\n\n\n\n<p><br>If this period is missed, it becomes difficult to control jawbone growth, making it the most critical golden time in pediatric orthodontics.<\/p>\n\n\n\n<p><br><strong><em>2) When the chin is too retruded (weak chin, Class II malocclusion)<\/em><\/strong><\/p>\n\n\n\n<p><br>This is a case where the upper jaw grows faster than the lower jaw.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Optimal timing: around ages 10\u201312<\/li>\n\n\n\n<li>It\u2019s less time\u2011critical than an underbite, but it is still important to treat it during the growth period.<\/li>\n<\/ul>\n\n\n\n<p><br>In this case, a face mask or intraoral appliance must be worn for long periods, so cooperation from both the child and the caregiver is essential. \u00a0<br>Because the appliance must be worn consistently at home to be effective, the child\u2019s cooperation plays a decisive role in the success of pediatric orthodontic treatment.<\/p>\n\n\n\n<p><strong><em><br>3) When the teeth are crooked (crowding, alignment issues)<\/em><\/strong><\/p>\n\n\n\n<p>This is one of the most common pediatric orthodontic cases. &nbsp;<\/p>\n\n\n\n<p>This happens when the front teeth come in crooked as they transition to permanent teeth, or when there isn\u2019t enough space and crowding occurs.<\/p>\n\n\n\n<p>But the important point is, &nbsp;<\/p>\n\n\n\n<p>It does not mean that pediatric orthodontic treatment is always necessary just because the teeth are crooked.<\/p>\n\n\n\n<p>The necessary analytical factors are as follows.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Jaw size<\/li>\n\n\n\n<li>Space for the teeth to erupt<\/li>\n\n\n\n<li>Future growth potential<\/li>\n<\/ul>\n\n\n\n<p><br>By analyzing these three factors, we determine whether first\u2011phase orthodontic treatment is necessary or if second\u2011phase treatment during middle or high school will be sufficient.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"327\"

worry a lot when there is a wide gap between the front teeth. \u00a0<br>However, the timing of treatment varies depending on the cause, so a gap alone does not mean that pediatric orthodontic treatment should begin immediately.<\/p>\n\n\n\n<p><br><strong>\ud83e\uddb7 Why is pediatric orthodontic treatment during the growth period important?<\/strong><\/p>\n\n\n\n<p>Growth\u2011phase orthodontic treatment goes beyond simply aligning the teeth evenly, &nbsp;<\/p>\n\n\n\n<p>It is the only period during which the growth direction of the jawbone itself can be modified.<\/p>\n\n\n\n<p>Once a person becomes an adult, jawbone growth stops, so only the teeth can be moved, but &nbsp;<\/p>\n\n\n\n<p>Children\u2019s jawbones are still growing, so orthodontic treatment that utilizes the growth plates is possible.<\/p>\n\n\n\n<p>Especially in cases of underbite or a recessed chin, these conditions are closely related to the jawbone\u2019s growth pattern, &nbsp;<\/p>\n\n\n\n<p>The growth period is essentially the most effective\u2014and often the only\u2014time for pediatric orthodontic treatment.<\/p>\n\n\n\n<p><br><strong><em>\ud83e\uddb7 Phase 1 vs.

class=\"wp-block-list\">\n<li>A child\u2019s jawbone is still in the growth phase.<\/li>\n\n\n\n<li>Because a dental implant fuses with the bone, it does not move as the child

My six year old\u2019s front teeth are coming in crooked. Should we start pediatric orthodontic treatment right away<\/p>\n\n\n\n<p>A. It is difficult to determine based on the alignment of the front teeth alone. We decide on first stage orthodontic treatment after space analysis<\/p>\n\n\n\n<p>Q2. My child has an underbite and is ten years old Is it too late<\/p>\n\n\n\n<p>A. Ages seven to eight are the most effective, but it cannot be said that it is too late. A professional evaluation is essential<\/p>\n\n\n\n<p>Q3. My child has difficulty wearing the appliance properly Is pediatric orthodontic treatment still possible<\/p>\n\n\n\n<p>A. Cooperation is very important in growth\u2011phase orthodontic treatment. Jaw growth correction especially requires wearing the appliance at home as well<\/p>\n\n\n\n<p>Q4. My child\u2019s baby tooth fell out too early Is that okay<\/p>\n\n\n\n<p>A. Without a space maintainer, the permanent tooth is more likely to erupt crooked<\/p>\n\n\n\n<p>Q5. When a tooth falls out can I put it in water<\/p>\n\n\n\n<p>A. Water is strictly prohibited.
