简要总结
The purpose of this research study is to assess the clinical effectiveness of a minimally invasive alveolar microperforation procedure to achieve accelerated tooth movement in patients undergoing orthodontic treatment for orthognathic surgery. "Accelerated tooth movement" means that Microperforation technique may help complete orthodontic treatment sooner than would be expected in conventional orthodontic treatment
详细描述
SAMPLE: For this prospective study, 22 subjects were selected, with skeletal discrepancies randomly divided into two groups: 1 - accelerated tooth movement technique (ATMT) and 2 - Control .
METHODS: MATERIAL - Orthodontic records done in two times, initial and preoperative; Plaster models of dental extracted jaw every 28 days converted in digital models; Cone Beam Computed tomography done in two times, initial and in the end of extraction space closure.
METHODS: Pre-molar extraction was performed before the Orthodontic Treatment to eliminate the RAP from the tooth extraction. After, at minimum 8 months for leveling, the extraction space closure was activated with light orthodontic traction (200 g each side) in anterior teeth, to maintain therapeutic osteopenia until contact point between the canine the second pre-molar is reached. Slide mechanic was chosen to performed anterior retraction on TADs in IZC.
Cortical perforations - ATMT Group: Flapless cortical micro-osteoperforations has been performed in the dental extraction area. Surgical protocol is flapless to preserve periodontal health. After local anesthesia, 3 micro osteoperforations are done with manual instrument, between the contour of free gum and tooth apex, and the canine and second pre-molar roots. The perforations near each tooth adjacent to the extraction area has 6-8 mm depth.
Results: On digital models - shortest distance between two adjacent teeth to the extraction space will be measured until the space closure.
