Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of oral cavity, and particularly relates to a multifunctional children's arch expander and a manufacturing method thereof. Background Art
[0002] As the human jaw degenerates, children are increasingly prone to severe jaw underdevelopment, both in width and length. Dental expansion is an effective treatment for malocclusion in children with small dental arches. When a child's dental arch is small and the crowns are too wide, resulting in crowded or irregular teeth, expansion therapy can be achieved by wearing orthodontic braces to gradually widen the arch, providing ample space for the teeth to align properly. This not only improves dental aesthetics but also reduces the need for tooth extraction during orthodontic treatment. However, it's important to note that traditional expanders (such as spiral expanders) can cause some discomfort during use, such as damage to the oral mucosa and pain or discomfort. Children's orthodontic clear braces can also be delayed in achieving effective expansion due to occlusal issues and the rapid loss of brace distalization force. Therefore, this integrated bimaxillary expansion brace allows patients to remove it freely and maintains open occlusion during wear, providing a more effective and stable expansion of the teeth without occlusal interference. Summary of the Invention
