statement of problem: a recent technique (mbt) has been introduced for easy and efficient orthodontic treatment by means of straight wire fixed appliances. although this technique has many advantages, in space closure stage causes up righting problem in upper incisors, which should be adjusted by applying additional torque in anterior region. purpose: the purpose of this clinical trial was to d...

BACKGROUND The aim of this study was to investigate the efficacy of orthodontic treatment using the Invisalign® system. Particularly, we analyzed the influence of auxiliaries (Attachment/Power Ridge) as well as the staging (movement per aligner) on treatment efficacy. METHODS We reviewed the tooth movements of 30 consecutive patients who required orthodontic treatment with Invisalign®. In all...

Objective: The aim of present study was to investigate the difference of torque control during intrusion force in incisors with normal, under and over-torque in lingual and labial orthodontic systems through finite element analysis. Material and Methods: 3D models of an upper right central incisor with different torques were designed in Solid Works 2006.The models were transferred to the ANSYS ...

The angle of long axis of tooth crown is called tip in mesiodostal and torque in faciolingual direction. Both have special importance for producing an ideal occlusion. The aim of the present study was determination of the average tip and torque of each permanent tooth in well treated patients with edgewise system compare to control group with normal occlusion. In this stu...

To evaluate the torque expression of right permanent maxillary central incisor with varying bracket positions and to compare same tooth different crown-root angulations. Finite Element Models Maxillary Central Incisor were used for simulation various angles. Three FEM models a angles (170˚,175˚,180˚, 165°) constructed heights subjected 30° labial root resultant expressions evaluated. The model ...

In this case report, we present an unusual approach that was used to treat a 14-year-old patient with a bilateral canine-premolar transposition and a missing maxillary lateral incisor. The orthodontic treatment involved maintaining the transposition and creating a space for lateral incisor replacement. Toward the end of the treatment, accentuated buccal root torque was performed, and lateral gr...

The objectives of this study were to evaluate (1) the impact of maxillary incisor inclination on the aesthetics of the profile view of a smile, (2) to determine the most aesthetic inclination in the profile view of a smile and correlate it with facial features, and (3) to determine if dentists, orthodontists, and laypeople appreciate differently incisor inclination in smile aesthetics. A smilin...

We have shown in a previous article [1] how a relatively simple unipoint system extemporaneously achieved the correction of tooth migration in cases of very advanced periodontal disease. Here, we are going to show how the same attachments in conjunction with micro-screws placed on each side of the pyriform aperture and in both sides of the mandibular symphysis, made it possible to correct an ex...
