The Effects of Diameter, Length and Insertion Method on the Stability of Orthodontic Miniscrew
Tóm tắt
This study investigated the maximum insertion torque value (ITV) of different dimensions of orthodontic miniscrews for primary stability, and further explored the effects of continuous rotation insertion and intermittent rotation insertion methods on the stability of orthodontic miniscrews.
Six different dimensions of orthodontic miniscrews, three lengths (6.0, 8.0, and 10.0 mm) and two diameters (1.4 and 1.6 mm), were inserted into the artificial bone specimens by using a torque testing machine, and continuous and intermittent rotation insertion methods were applied. There were a total of 12 groups, and each group was composed of five samples. The torque testing machine was used to record the maximum ITV and torque-time curve. The median maximum ITV of the orthodontic miniscrews in the 12 groups ranged between 11.5 and 23.7 N cm. In orthodontic miniscrews of 1.6 mm diameter, regardless of the insertion method, the ITV increased with length. For orthodontic miniscrews of 1.4 mm diameter, there was no statistical difference in the maximum ITV regardless of the inserted method as the differences in length were negligible (only 2.0 mm). Furthermore, there was no statistical difference in the maximum ITV required for the continuous rotation insertion and intermittent rotation insertion methods between inserting orthodontic miniscrews of similar dimensions. The maximum ITV mostly increased with the increase in the diameter or length of the orthodontic miniscrew. There was no statistical difference in the maximum ITV required for continuous rotation and intermittent rotation insertion methods.
