Abstract:

To evaluate the effects of the Damon technique, Smart Clip technique and MBT technique in nonextraction samples using the peer assessment rating (PAR) index. Methods90 cases were selected to assess pretreatment and posttreatment dental casts. Based on the same pretreatment PAR score, samples were divided into three groups, each had 30 cases. The data were statistically analyzed. ResultsThe  posttreatment PAR score of the anterior tooth alignment in the Damon group was a little bit higher than in the other two groups. There were no significant differences in other PAR scores. The treatment period of the Damon group was shorter than that of the MBT group by 4.36 months, and of the Smart Clip group was longer than that of the MBT group by 2.65 months. ConclusionThe Damon technique, Smart Clip technique and MBT technique produced the same treatment results, but the treatment period was different.
