2018 Annual Session Conference

Accelerated Osteogenic Orthodontic Tooth Movement: The Evidence

‐ May 6, 2018 2:55pm

Surgically or periodontally assisted osteogenic orthodontics (SAOO or PAOO) involves bone perforations adjacent to the teeth to be moved. The purpose of perforations is to create trauma resulting in the regional acceleratory phenomenon (RAP) to produce an increase in the speed of tooth movement, shortening treatment times. There are numerous reported methods for inducing the RAP to affect the speed, amount and extent of tooth movement; however, many reports are anecdotal, or commercially promoted. This presentation will include the current evidence related to both invasive and minimally invasive techniques, as well as the use of bone grafting as an adjunct procedure.

Learning Objectives:

  • Discuss the evidence related to the various PAOO procedures reported to stimulate the RAP.¬†
  • ¬†Discuss the efficacy of the various PAOO procedures and their limitations.
  • Determine those cases where PAOO may be beneficial.
