Abstract

BackgroundThis study aimed to investigate the effects of a minimally invasive, flapless procedure to enhance tooth movement in both jaws and to determine whether this triggers the acceleration when repeated monthly.Material and MethodsThe sample consisted of thirty-two individuals whose orthodontic treatment required canine retraction. They were divided into an experimental group and control group. Osteopunctures were performed using orthodontic mini-screws at the distal aspects of the canine teeth at the beginning and on the fourth week of distalization in the experimental group. The control group was treated with conventional mechanics. All canines were retracted. The rates of canine distalization, rotation, and tipping were measured on the first, fourth, and eighth weeks of distalization. First molar anchorage loss was also measured. Intergroup and intragroup analyses were performed.ResultsFlapless osteopuncture-facilitated tooth movement resulted in greater canine distalization and reduced molar movement in the maxilla in the experimental than in the control group during the first month of distalization. In addition, the extent of upper canine movement was significantly higher in the experimental group in the first month than in the second. No differences in canine and molar movement in the mandible were observed between the two groups.ConclusionsOP, as applied in this study, is an effective method for increasing the rate of tooth movement in the maxilla. Repeating the procedure monthly does not appear to show a major advance of tooth movement. Key words:Accelerated tooth movement, flapless osteopuncture.

Highlights

The growing awareness of good health has increased the demand for orthodontic treatment
No statistically significant differences were found for the canine distalization (CD) rate between the first four weeks and the second four weeks both in the maxilla and in the mandible. -Intergroup comparison The four parameters (CD, canine rotation (CR), canine tipping (CT), and molar mesialization (MM)) were assessed in the intergroup comparison
CD, Canine distalization; CT, Canine tipping; CR, Canine rotation; MM, Molar mesialization; ns, non significant (p>0.05); SD, Standard deviation; * significant at 95% level (p

Summary

Introduction

The growing awareness of good health has increased the demand for orthodontic treatment. Care was taken to ensure a distance of one mini-screw diameter between each perforation In both groups, mini-screws were placed between the roots of the second premolar and those of the first molar teeth to support anchorage. FA, fixed appliances; LA, levelling-alignment; CD, canine distalization; P, photos; AI, alginate impressions The data on both OP and control groups were evaluated under two main headings: intragroup and intergroup. -Intragroup comparison Only the CD rate was examined and compared between the first four weeks (T1–T3) and the second four weeks (T3–T4) of distalization both for the OP and control groups. No statistically significant differences were found for the CD rate between the first four weeks and the second four weeks both in the maxilla and in the mandible. No statistically significant differences were found in the mandible for all the parameters (Table 3)
