the routine treatment for rotated maxillary incisor is a fi xed appliance, but in some instance the use of this method is impossible. in addition, in only limited cases of rotation, removable appliance is applicable. in this study, the use of a semi-removable appliance is presented, which has some benefi ts over the other methods. in this study, the corrections of about 70 -90° rotation of the ...

Introduction: Space maintenance in primary dentition in patients with early loss of several primary molars is a clinical challenge for pedodontists. In these cases, the conventional distal shoe appliance cannot be used and the efficacy of removable appliances is questionable. Thus, appliances with special designs providing increased patient acceptance and optimal efficacy are required in these ...

• Extraction of deciduous teeth no more than two weeks previously. • Absence of periodontal disease or any other pathology. • Absence of abnormal dental conditions such as crossbite, open bite, or deep bite. • Absence of carious lesions on the buccal surfaces of the abutment teeth. • Good oral hygiene. • Ability to attend follow-up appointments as required. Twenty-seven children (16 male and 11...

The present study was performed to test the tendency for plaque and calculus build-up along the wire of different types of bonded orthodontic canine-to-canine retainers, whether the presence of such retainers causes any damage to the teeth involved, the failure rate of the retainers, and any changes in incisor alignment during a 3-year period of retention. The four test groups received either r...

This study evaluated histologically the temporomandibular joint and posterior ramal regions in juvenile Rhesus monkeys whose mandibles had been positioned forward with a Herbst appliance. Acrylic splint Herbst appliances were bonded to the maxillary and mandibular dental arches of 20 male juvenile animals. The animals were killed at 3-, 6-, 12-, and 24-week intervals after appliance placement. ...

This case report presents the interceptive orthodontic treatment of a boy, aged 8 years 4 months with a Class I malocclusion with severe transverse maxillary deficiency and complete maxillary crossbite and correction using Haas expansion and fixed appliance. The treatment goals were to correct the posterior crossbite and anterior crossbite and restore the normality of the dentition and occlusio...

BACKGROUND Root resorption is one of the most common and undesirable sequelea of orthodontic treatment. The aim of this study was to evaluate the amount of root resorption in permanent incisors during 3 month active period of fixed orthodontic appliance therapy using periapical radiographs. METHODS Periapical radiographs of a total of 138 permanent teeth (n = 138, mandibular n1 = 52, maxillar...

facial deficiency or true mandibular prognathism are difficult to manage nonsurgically, particularly when a hyperdivergent mandibular growth pattern creates an anterior open bite. For the past 25 years, early growth modification of midfacial deficiency with expansion and facemask therapy has been the standard treatment for Class III malocclusions.1,2 A disadvantage of this ap proach is that it ...
