Summary

The study aims to compare the effect of periodontal accelerated osteogenic orthodontics (PAOO) with horizontal or vertical releasing incisions on operation time, healing, adverse effects, and effectiveness of bone augmentation. Methods: A total of 22 patients requiring PAOO surgery due to orthodontic treatment were enrolled in this trial, and randomly divided into test or control group, consisting of 11 subjects in each. The test group will receive PAOO with horizontal extending incisions on both sides of the flap; while the control group will receive PAOO with vertical releasing incisions; the two groups use the same surgical technic except for the incision design. Outcome measures include: operation time, postoperative scar, radiographic data (alveolar height and alveolar ridge thickness), gingival thickness, etc. Clinical evaluation will be performed at 1 week, 2 weeks, 3months, 6 months and 12 months after operation.

Conditions

• Malocclusion

Interventions

Type	Name	Description
PROCEDURE	horizontal extending incision	a papilla preserving incision will be made on the labial side of the front teeth with a thin alveolar bone or dehiscence and/or fenestration. Then horizontally extending incisions will be added to each side of the initial incision, extending one to two teeth beyond the defected area, before a full-thickness flap is lifted.
PROCEDURE	vertical releasing incision	a papilla preserving incision will be made on the labial side of the front teeth with a thin alveolar bone or dehiscence and/or fenestration. Vertical releasing incisions will be made on each side of the initial incision before a full-thickness flap is lifted. The incision formed an oblique trapezoidal flap with a wider base.
