Which plan is better and why for 8yr old class ii overbite w/ mild crossbite? expander, 12mo of headgear, partial braces or braces 3-6mo & koi

AAFO: Try looking up one at the american academy for functional orthodontics website. Interceptive treatment of a particular condition during growth is generally a better choice in terms of overall results. It often can minimize the need for extraction of permanent teeth, extensive orthodontics that may include headgear and maybe orthognathic surgery.

Overbite: If the cross bite is in the posterior teeth an expander would be good. Partial braces can also correct the arch configuration to allow the permanent teeth to erupt into more ideal relationship. This may reduce or possibly eliminate the need for full braces later. Consult with your dentist if he does braces, or have an orthodontist examine the child.

Best advice consult with qualified orthodontic specialist. They are dento-facial growth and development experts. While many dentists straighten teeth, orthodontists harmonize faces. Any qualified orthodontist welcomes 2nd opinions.

Likely expander: hard to really say based on your description and not seeing your son, but I would guess that an expander would work fine and be the least painful or difficult for him

See an Orthodontist: Many orthodontists offer an initial complimentary consultation. This allows you to find out what type of treatment is recommended for your individual situation and get all your questions answered. Take care.
