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 ...

BACKGROUND AND AIM: Severe rotation of tooth is one of the most common problems in orthodontics and considered as a developmental phenomenon. These rotations can cause cosmetic problems, gingival recession, and traumatic occlusion. By using removable appliances, severe rotations can be treated. Furthermore, gingival damage, tooth attrition, and transposition of other teeth could be prevented. E...

Orthodontists from different backgrounds may have different opinions about removable and fixed orthodontic appliances, but there have been few objective comparisons of their relative treatment effectiveness. It is the purpose of the present study to analyze objectively the effectiveness of these two types of appliances. Eighty cases involving patients who had been treated with removable applian...

The aim of this study was to compare the ability of 46 isolates of Candida albicans to produce mycelial form with oral source in three groups of individuals including, removable appliance wearers, non-wearers and oral medicine patients. Saliva samples were obtained from all subjects along with a foam imprint from the fitting surface of the upper removable appliance in the case of patients. Colo...

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 ...

The aim of this case report was to introduce an appliance for correcting severe rotation of anterior teeth in the mixed dentition period. A 9-year-old Iranian boy with a mixed dentition Class I malocclusion complained of a severely rotated of upper right central incisor. There was a mesiodens between the central incisors. The supernumerary tooth was first extracted and then a Whip appliance whi...

the present report describes orthodontic treatment of a patient with skeletal class iii malocclusion and maxillary hypoplasia. to correct the retrusive maxilla, the treatment plan included an intra-oral removable device. it had the advantages of good patient cooperation, ease of construction and effective modification. forward growth of the maxilla, minimal downward and backward rotation of the...

Fifty-two patients (35 female, 17 male) completed questionnaires related to their experiences during the first 7 days of appliance wear (31 fixed, 21 removable) and then after 14 and 90 days. Most problems relating to discomfort and pain resolved within 4-7 days. The problems encountered with fixed appliances were generally more severe than with removable appliances. Swallowing and speech were ...

Anterior crossbite correction in early mixed dentition is highly recommended as this kind of malocclusion do not diminish with age. Uncorrected anterior crossbite may lead to abnormal wear of the lower incisors, dental compensation of mandibular incisors leading to thinning of labial alveolar plate and/or gingival recession. There are several methods for solving this problem. In this article we...
