OBJECTIVE The purpose of this study was to assess the efficiency of compensatory orthodontic treatment of patients with mild Class III malocclusion with two preadjusted bracket systems. METHOD Fifty-six matched patients consecutively treated for mild Class III malocclusion through compensatory dentoalveolar movements were retrospectively evaluated after analysis of orthodontic records. The sa...

statement of problem: some vertical changes might be observed during the first stage of orthodontic treatment, aligning and leveling. purpose: the aim of this study was to evaluate dental and/or skeletal vertical changes occurring in the first stage of preadjusted orthodontic treatment. materials and methods: fourteen patients with an average age of 14.1 years were selected for this study. prea...

Manufacturers offer various prescriptions of preadjusted brackets for use in the "straight-wire" orthodontic technique. However, the need to incorporate bends in the rectangular wires during orthodontic finishing has led to concerns regarding the type of prescription chosen and the credibility of information provided by the manufacturer. The aim of this study was to compare the slot angulations...

OBJECTIVE The aim of the present study was to verify the torque precision of metallic brackets with MBT prescription using the canine brackets as the representative sample of six commercial brands. MATERIAL AND METHODS Twenty maxillary and 20 mandibular canine brackets of one of the following commercial brands were selected: 3M Unitek, Abzil, American Orthodontics, TP Orthodontics, Morelli an...

objective: the purpose of this study was to evaluate the dental movements of the labial segment and the canines during leveling and alignment using pre-adjusted appliances and light forces with the mbt technique. the effect of lacebacks on the horizontal movement of the first molars was also assessed. materials and methods: fourteen patients with a mean age of 14.08 years were selected for this...

BACKGROUND The objective of this study was to compare the frictional forces generated by three types of monocrystalline ceramic brackets coupled with conventional elastomeric ligatures (CEL) and nonconventional elastomeric ligatures (NCEL) during the alignment of apically displaced teeth at the maxillary arch. METHODS All tests (a total of 480 tests) were carried out in a dry state on a unive...

The difficulty of managing this reverse anchorage potential has led to an increase in the use of extraoral forces, functional appliances, and even orthognathic surgery to correct malocclusions with relatively slight sagittal discrepancies. In his last published article, Angle advocated angulated bracket placement that would tip the crowns of the maxillary teeth distally to correct a Class II, d...

: To compare the aligning efficiency, pain experienced by patient during alignment and post third order values of anterior teeth in I arch (study) group conventional NiTi (control) wire group. A prospective clinical study. total 40 dental arches (maxilla/mandible) were divided into 2 study groups with 20 each based on selection criteria. Group I. Twenty (maxillary/mandibular) having 0.018” prea...
