The purpose of this study was to compare the effects of active and passive lacebacks on antero-posterior position of maxillary first molars and central incisors during leveling phase. Twenty-three subjects with Class I and Class II malocclusion were treated with first premolars extraction using preadjusted appliances (MBT 0.022-inch brackets). The leveling phase was performed with stainless ste...

Aim. To compare and evaluate the static frictional resistance offered by the four different types of ligation methods in both dry and wet conditions and at different durations when immersed in artificial saliva. Material and Methods. Alastik Easy to Tie modules, Super Slick Mini Stix elastomeric modules, Power "O" modules, and 0.009(″) Stainless Steel ligatures were used to compare the static f...

BACKGROUND To test the null hypothesis that there is no difference in the apical root resorption seen after orthodontic treatment with the conventional brackets and the self-ligating brackets. METHODS Pre-treatment and post-treatment periapical radio-graphs of 70 patients, (35 treated with the Damon3 0.022" bracket and 35 with the 0.022" 3 M bracket) were studied. The long cone paralleling te...

Background and Aim: Recycling of brackets can significantly reduce the price of fixed orthodontic appliances but if the bond is more prone to failure during treatment, this potential benefit will disappear. The aim of this study was to investigate the effect of chemical recycling on bond strength of metal orthodontic brackets and failure pattern of recycled brackets. Material and Methods: In th...

Background: Bodily alignment of teeth that are blocked out of the arch such as a lingually placed lateral incisor, is often time consuming and difficult. Though several treatment methods are available for accomplishing this, these approaches have some drawbacks. Aim: To describe how Mollenhauer aligning auxiliary (MAA) can be adapted to bodily align lingually blocked-out lateral incisors in pre...

  Objective: Orthodontic wires should have high resistance against corrosion in the oral environment. Since the effect of pH on corrosion has been well recognized, this study sought to assess and compare the electrochemical corrosion of orthodontic brackets and wires of different brands in acidic artificial saliva.   Methods: This in vitro experimental study was conducted on 24 mandibular centr...

  Background and Aims: Orthodontic bracket failure during treatment is a common problem. With the introduction of low shrinkage composites the question is that whether: this sufficient has coefficient bond strength for bonding bracket during orthodontic treatment. The aim of this study was to compare the shear bond strength (SBS) of silorane-based and metacrylate-based composites to metal brack...
