Steel braces, that is, steel wire braces, and self-locking braces of the main differences are as follows:
One, the principle of different
1, steel wire braces: steel wire braces made of high-quality stainless steel wire, cross-section is diamond-shaped, mechanically rolled into the shape of a spring thread. Steel wire bushing diameter is larger than the screw hole, when the installation, the steel wire bushing is compressed and tightened, after the completion of the installation spring back to its original state, so that the steel wire bushing permanently fixed in the screw hole. Because of its larger diameter, so the steel wire bushing has a larger contact surface, and thus more solid than the original thread.
2, self-locking braces: the special Myojet self-locking bracket has a memory function that ensures that the archwire is in the correct position, which improves the effectiveness of movement of malocclusion and has a predictable treatment effect.
Two, the advantages are different
1, wire braces: threaded braces can form a high-precision internal thread in accordance with international standards, and its performance is better than the thread formed by tapping.
2, self-locking braces: accurate positioning, simplified treatment.
Three, different characteristics
1, steel wire braces: steel wire braces are divided into ordinary and locking type two, can be screwed into the metal or non-metallic materials in the threaded hole to form a high-strength, wear-resistant, high-temperature, shock, impact, corrosion-resistant performance of the standard M, MJ threads, and can be dispersed stress, protection of the substrate threads, which can comprehensively improve the performance of the use of screw holes to extend the service life of the machine. The service life of the machine can be extended.
2, self-locking braces: orthodontic treatment is shorter, mainly to reduce the time of operation of the alveolar groove, prolong the interval between follow-up, usually 3 months ahead of the completion of orthodontics.
