No results posted yet for this study

Summary

Corticotomy and micro-osteoperforation (MOP) have been proven to accelerate tooth movement and shorten orthodontic treatment time, compared to conventional treatment. MOP is less invasive; however, it is unclear whether it is as effective as a corticotomy. The purpose of this study was to compare the maxillary canine retraction achieved by these techniques.

Conditions

  • Malocclusion, Class I/II

Interventions

PROCEDURE

Micro-Osteoperforations

MOPs were performed with a stainless-steel manual drill tip that had 1.6mm diameter with an adjustable depth set to 5mm (Excellerator® RT; Propel Orthodontics, Milpitas, CA). Six perforations were made along 2 parallel vertical lines (each line with 3 holes spaced \~2mm apart) distal to the canine and perpendicular to the buccal cortical bone. The mini-screws were placed. A NiTi closed-coil spring was placed and secured with a 0.014"SS ligature wire at the canine and mini-screw. A Dontrix gauge was used to measure the force (150g)

PROCEDURE

Corticotomy

A full-thickness labial mucoperiosteal flap was reflected. Two vertical corticotomies (1 mesial and 1 distal to the canine) were performed. The cortical bone was cut 2 to 3 mm below the alveolar crest towards the apex, until bone marrow was exposed. Cortical-cancellous bone grafts (0.5cc; PuraGraft, Kingwood, TX) were placed at the corticotomy sites. The mini-screws were placed. A nickel-titanium (NiTi) closed-coil spring was placed and secured with a 0.014"SS ligature wire at the canine and mini-screw. A Dontrix gauge (Orthopli Corp., Philadelphia, PA) was used to measure the force (150g)
