Effect of surgically facilitated accelerated orthodontics on treatment duration, root resorption and bone density

Introduction: The use of orthodontic treatment in adult patients for the treatment of malocclusion is becoming more common. But the major disadvantages of conventional orthodontic technique are the time consumed for the treatment (18 – 24 months), root resorption and formation of fenestrations and dehiscence. Periodontally Accelerated Osteogenic Orthodontics (PAOO) is a surgical technique which results in an increase in alveolar bone width, shorter treatment time, increase post-treatment stability, and decrease in the amount of apical root resorption. Objectives: The objective of the study was to evaluate the effect of Periodontally Accelerated osteogenic Orthodontics (PAOO) with surgical bur and piezicision on: Duration of orthodontic space closure, amount of root resorption, and the bone density. Materials and Methods: Forty subjects who needed orthodontic treatment were randomly selected and divided into two groups. Group I consists of 20 subjects who were selected for Periodontally Accelerated Osteogenic Orthodontics (PAOO) with surgical bur Group II: consists of 20 subjects who were selected for Periodontally Accelerated Osteogenic Orthodontics (PAOO) with peizocision. Patients were recalled at baseline, 3, 6, 9 and 12 months and were evaluated for amount of retraction, bone density, root resorption and detection of fenestration and dehiscence. Cone Beam Computerised Tomography (CBCT) was used to evaluate the bone density, root resorption and for the detection of fenestration and dehiscence. Results: In subjects where corticotomy was carried out with surgical bur the treatment time was less as compared to PAOO with peizocision. Group I had a mean retraction of 5.99 ± 0.5 mm after 3 months (p<0> Conclusion: PAOO with surgical bur (Group I) decreases the treatment time as compared to piezocision (Group II). Amount of root resorption in Group I which was around 0.34 mm and that of Group II was around 0.51mm which is very minimal and increase in the bone density was seen in the post-operative CBCT.
