As you know PAOO (Periodontaly Accelerated Osteogenic Orthodontics) is a REVOLUTIONARY effective treatment approach in adults to decrease treatment time and reduce the risk of root resorption and relapse. Treatment time can be reduced up to 4.5 months with 70% less chance of root resorption and relapse. (Supported by periodontics and orthodontics literature). In many cases it can eliminate the indication of some orthognatic surgeries. Indications of the procedure are dentoalveolar discrepancies such as:

  • Severe Crowding, Open bite, Palatal
  • Expansion/lingual or buccal
  • Segmental movements, CI II /CI III
  • Relations, Rotations and more.
