Background: Periodontally accelerated osteogenic orthodontics (PAOO) combines periodontal therapy with\northodontic therapy, which minimises treatment time. This study compared the effectiveness of a bovine-derived\nxenograft with that of bioactive glass when combined with PAOO for the treatment of adult patients with\nmoderate crowding of the teeth.\nMethods: In this prospective, single-masked clinical trial, 33 orthodontic patients (20 women, 13 men; mean age\n21.2 Ã?± 1.43 [18 âË?â?? 27] years), were randomly allocated to one of three groups. Group 1 underwent a modified\ncorticotomy technique on the labial side only, whereas group 2 was treated with the same technique combined\nwith PAOO using a bovine-derived xenograft and group 3 was treated in the same way but combining PAOO with\nbioactive glass. The total treatment duration was recorded from the start of active orthodontic treatment,\nimmediately after corticotomy, and at the time of debonding. Probing depth was evaluated clinically and bone\ndensity and root length were evaluated radiographically on the day of surgery (baseline, T1), post-treatment at\ndebonding (T2), and 9 months post-treatment (T3).\nResults: The duration of orthodontic treatment was markedly reduced to an average of 11.4 Ã?± 0.14 weeks in all\ngroups. All probing depths were < 3 mm, the interdental papillae were well preserved, there was no loss of tooth\nvitality, and there was no evidence of significant apical root resorption at any time interval. All groups showed a\ndecrease in mean bone density at T2 followed by an increase at T3. The net percentage change that occurred\nbetween baseline and 9 months post-treatment was significantly different between the three groups. Groups 2 and\n3, where grafts were incorporated, demonstrated a statistically significant greater increase in bone density than\ngroup 1 at T3.\nConclusion: Combination of orthodontic treatment and periodontal surgery is an effective treatment for adult\npatients that decreases the duration of active treatment and reduces the risk of root resorption. Use of a bovine derived\nxenograft with modified corticotomy provided superior benefits in terms of increased bone density than\ndid the use of bioactive glass.
