Overjet and Mandibular Retrusion in Children? Try the Frankel 2 Appliance
Posted: May 28 , 2026
Many parents notice that after their children start losing baby teeth and growing permanent teeth, the upper teeth significantly overlap the lower ones, a condition commonly known as overjet. From the side view, the chin also appears receded. Medically, this is classified as Class II malocclusion. Without timely intervention, it may affect the child's facial profile and chewing function. For such issues, orthodontists often recommend the Frankel 2 appliance.
As a removable orthodontic device, the Frankel 2 appliance consists of a lower lip bumper, buccal shields, lower base plate and steel wires, and children can take it on and off by themselves. Its core function is to guide the mandible forward, correct occlusal relationship and boost the normal development of the mandible. It delivers particularly remarkable results for children under 10 who are in the growth and development period. Generally, obvious improvements can be observed after six months to one year of wear.
Different from fixed braces that are bonded to teeth, the Frankel 2 appliance can be removed during meals and tooth brushing, bringing great convenience to daily use. It is mainly worn at night for sufficient hours, and extra wearing time during the daytime is advised as directed by dentists. Numerous parents have reported that after months of consistent wear, their children's overjet is alleviated and the chin looks more proportionate. It should be noted that this appliance must be customized and adjusted by professional dentists, and regular follow-up visits are essential to guarantee the treatment outcome. If your child has similar dental problems, consult an orthodontist to check if the Frankel 2 appliance is a suitable option.
Frankel 2 appliance is an effective solution for kids with overjet and mandibular retrognathia, which works well during children's growth stage with easy operation and comfortable wearing experience.
