Periodontally Accelerated Osteogenic Orthodontics (PAOO) vs Osteoperforations (A Review on Periodontal Reactions to Orthodontic Tooth Movement)

Abstract

A high number of adult patients are undertaking orthodontic treatment now because of the newer methods, technology, and innovations available in the market. Orthodontic profession is continually looking for new ways to perform treatment effectively for such patients, as there are many differences in the biology, motivation, and treatment objectives between adults and children. Aligner therapy and mini-implants are some of the ways of managing orthodontic treatment for adult patients. Treatment time is a concern for adult patients and methods to accelerate the orthodontic tooth movement have been a focus in the orthodontic field. Periodontal accelerated osteogenic orthodontics (PAOO) is a surgical procedure that is performed with a combination of alveolar corticotomy, bone grafting, followed by orthodontic treatment. This procedure uses the principle of regional acceleratory phenomenon (RAP). Another procedure commonly used for accelerated orthodontic tooth movement is osteoperforations. This is a minimally invasive procedure, which does not include a flap surgery. The purpose of this article is to describe the differences between adult and children periodontal tissues, the use of different appliances for adult treatment, how orthodontic treatment has been modified for adult patients, and the detailed explanation of procedures for accelerating orthodontic tooth movement such as PAOO and osteoperforations and the potential complications
