Application of surgical periodontics for accelerated orthodontic correction of class ll division l malocclusion with skeletal discrepancy

Background There is a constant pursuit for substituting orthognathic surgical options by minimally invasive pre-orthodontic surgical procedures. Application of osseous resective surgery for alveolar reshaping is referred to here as "surgical periodontics for accelerated orthodontics". A parallel randomized clinical trial was designed to evaluate the clinical outcome of class 2 division 1 malocclusion with skeletal discrepancy using pre-orthodontic surgical procedures, comparing periodontally accelerated osteogenic orthodontics with surgical periodontics for accelerated orthodontics.

Methods Twenty-four adult orthodontics patients selected for this study were randomly divided into 2 equal groups. One group was treated with periodontally accelerated osteogenic orthodontics with augmentation grafting and the other was with surgical periodontics for accelerated orthodontics. These procedures were followed by fixed orthodontics treatment. Comparative evaluation of alveolar bone thickness was done by cone beam computed tomogram for both the groups.

Results The cephalometric parameters, A point nasion B point (ANB) angle and over jet of these subjects before and after the surgical interventions at three, six and twelve month’s intervals were compared to the base values, showing changes within 3 months when treated with surgical periodontics for accelerated orthodontics and within 6 months when treated with periodontally accelerated osteogenic orthodontics, without significant change in periodontal supporting alveolar bone thickness.

Conclusions Surgical periodontics for accelerated orthodontics and periodontally accelerated osteogenic orthodontics are effective pre-orthodontics surgical procedures for accelerating orthodontic treatment, without bringing any change in periodontal alveolar bone thickness.
