How to Deal with Your Child’s Class II, Division 2 Bite

Class II, Division 2 Malocclusion occurs when your child’s upper anterior teeth are tilted back toward his or her mouth, causing the lower jaw to be pushed back in a retruded positon. While many patients suffer from Class II, Division 2 Malocclusion, these cases are easily treatable! Once your child’s smile has been classified as Class II, Division 2 Malocclusion, treatment is considered if the “overjet,” or the amount of space the lower teeth overlap the upper teeth, is greater than 6mm. Once the overjet is determined, the goal is then to correct the Class II position to a Class I position, which is the state of an ideal smile.

A large percentage of patients with Class II, Division 2 Malocclusion suffer from resulting medical conditions, including TMJ and breathing disorders. This type of malocclusion also increases your child’s risk of trauma to his or her upper incisors, especially if his or her lips do not sufficiently protect his or her smile. Correcting malocclusion is necessary for both aesthetic and medical reasons. Not only will your child be able to speak, breathe, and eat easier, but his or her facial profile will be greatly enhanced, including a better nose proportion, fuller lips, and a broader smile.

Prior to treating Class II, Division 2 Malocclusion, the dental arches must be the appropriate size and shape. Once the dental arches are accurately developed, the upper anterior teeth will be adjusted to their ideal positions. This adjustment of the upper anterior teeth increases the “overjet,” because the lower jaw is still in a retruded position. Then, the lower jaw is corrected by pulling it forward. This adjustment to the lower jaw can be done surgically or by using a simple mouth appliance. Once the jaw positioning is fixed, your child’s smile can then be straightened through conventional orthodontics.

Parents, as you consider treating your child’s Class II Division 2 Bite, here are some questions you may be asking and some input that may help:

  • Should I wait or treat this now? Although early Class II, Division 2 Malocclusion treatment is typically more costly, it can result in a 40% less chance of trauma to your child’s upper incisors. Early treatments can also increase both the attractiveness of the facial profile and overall self-esteem.
  • How much of an impact will a functional appliance have on my child’s development? Functional appliances are extremely effective when correcting Class II incisal relationships, they can have a significant impact on your child’s health by correcting breathing issues, and they can alter facial feature development, but they won’t alter actual skeletal patterns to a meaningful degree. They won’t change what’s been pre-determined by your child’s genetics
  • Finally – if you’re wondering whether to get your child a fixed appliance or a removable appliance? There is much better patient cooperation with a fixed appliance, however there is no difference in the treatment results between fixed appliances and removable appliances. They both work. So consider your child when making this decision.
