Purpose:
To compare the effect of relieving dental crowding by using a newly designed low frictional force single-wing bracket and conventional MBT brackets on typodont model.
Methods:
Two replicated typodont models were made with a same crowded upper arch. The two different types of bracket were bound separately on two typodont models. Clinical course was simulated with warm bath. The typodont models' crowded upper arch was aligned with 0.014 NiTi. The data were analyzed for t test using SPSS12.0 software package.
Results:
In the MBT bracket group, the degree of the dental crowding reduced 2.58mm, compared with 5.49mm in the newly designed group.Significant difference between self-ligating brackets and conventional design was found between the two groups(P<0.05).
Conclusions:
It is indicated that the newly designed low frictional force single-wing-bracket relieves dental crowding faster than the conventional MBT bracket on typodont model.
