To date, the number of adult patients looking for aesthetic and comfortable alternatives to traditional fixed appliance therapies is increasing significantly. One of the biggest challenges an adult orthodontic patient faces is the time spent wearing the appliance: to accelerate orthodontic tooth movement and shorten treatment duration is thus a topical issue. Corticotomy is an effective and saf...
The availability of 3D dental model scanning technology, combined with the ability to register CBCT data with digital models, has enabled the fabrication of orthognathic surgical CAD/CAM designed splints, customized brackets, and indirect bonding systems. In this study, custom lingual orthodontic appliances were virtually designed by merging 3D model images with lateral and posterior-anterior c...
This study investigated the association of appliance type and tooth extraction with the incidence of external apical root resorption (EARR) of posterior teeth following orthodontic treatment. Pre- and posttreatment orthopantomograms were compared for 97 patients and a 4-grade ordinal scale used to measure EARR. The incidence of EARR was positively associated with tooth position (P < .001), appl...
background and objectives: long-term usage of fixed and removable orthodontic appliances creates a favorable environment for the augmentation of oral normal microflora particularly candida species, which can increases the risk of periodontal lesions. the aim of this study was to assess quantitative and qualitative alterations in the carrier rate of candida spp. after placement of fi...
OBJECTIVE To investigate by behavioral methods the relationship between emotional stress and pain during experimental tooth movement in rats. MATERIALS AND METHODS Sixteen male Sprague-Dawley rats (210 to 250 g) were divided into two groups. The experimental group was treated with an active Ti-Ni appliance, and the control group received a passive appliance. A force of 20 gf was delivered by ...

OBJECTIVE The aim of this study was to cephalometrically assess the skeletal and dentoalveolar effects of Class II malocclusion treatment performed with the Jones Jig appliance followed by fixed appliances. METHODS The sample comprised 25 patients with Class II malocclusion treated with the Jones Jig appliance followed by fixed appliances, at a mean initial age of 12.90 years old. The mean ti...
In orthodontics there has been a change in the treatment plan of crowding cases from extraction protocol. This was mainly due to introduction self-ligating bracket and temperature activated wires. Even though are certain exceptions, have evolved because its advantages such as low friction, shorter duration increased efficacy. Damon’s system existence since 1930 but it well developed past 30 yea...
The aim of this study was to evaluate the change in mandibular position during a two-phase orthodontic treatment of skeletal Class II malocclusion. Thirty consecutively treated Chinese male adolescents who had undergone two-phase treatment with Herbst appliance and fixed appliance and fulfilled the specific selection criteria were sampled. Cephalograms taken at T0 (before treatment), T1 (at the...
BACKGROUND Psychosocial consequences and post-operative anxiety in patients after fixed orthodontic treatment are important parameters that must be evaluated by clinicians not to effect patient and their parent's psychosocial mood negatively.
