AIM The metal ion released from the orthodontic appliance may cause allergic reactions particularly nickel and chromium ions. Hence, this study was undertaken to determine the amount of nickel, chromium, copper, cobalt and iron ions released from simulated orthodontic appliance made of new archwires and brackets. MATERIALS AND METHODS Sixty sets of new archwire, band material, brackets and li...

The introduction of mini-implants has broadened the range of tooth movements possible by fixed appliance therapy alone. The limits of fixed orthodontic treatment have become more a matter of facial appearance than anchorage. Many complex cases which would previously have required surgery or functional appliances can now be treated with fixed appliance therapy using mini-implants. A mutilated de...

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...

INTRODUCTION Hemifacial microsomia (HFM) is a birth defect involving craniofacial structures derived from the first and second branchial arches. Although it is a relatively uncommon malformation, it is the second most common craniofacial birth defect after cleft lip and palate (CL/P). CASE PRESENTATION This is a case report about the successful orthodontic treatment of a patient with mild hem...

Although maxillary central incisors impaction is not a high frequent clinical condition, it is responsible for some undesirable aspects of patients smile from esthetic and functional points of view. There are some etiologic factors associated to this dental disturbance but the scientific literature is consensual on determining the importance of the early diagnosis and proper intervention. This ...

This clinical case report describes the orthodontic treatment of an 8-year and 9-month old female patient with Angle Class I malocclusion, anterior crossbite and canine Class III relationship. Orthodontic treatment was carried out in two stages. The first one was orthopedic, while the second one included the use of a fixed appliance and the need for space gain for reshaping of maxillary lateral...

The fixed or removable orthodontic appliances mostly use intrinsic force to move teeth. is exerted by the appliance and dissipated against teeth supporting structures. skeletal Class II correctors evolved from various modifications of original activator. These reposition mandible in downward forward direction, activating attached associated muscle. resultant thus created transmitted not only bu...

BACKGROUND This study compared the oral hygiene and caries risk of patients treated with labial and lingual orthodontic appliances throughout a prospective evaluation of the status of the oral environment before and after bracket placement. METHODS A total of 20 orthodontic patients aged 19 to 23 years were included in the study and were divided into two groups: 10 patients wore Roth labial a...

This study compared the effects produced by two different molar distalizers, namely cervical headgear (CHG) and the intraoral pendulum appliance, associated with fixed orthodontic appliances. The headgear group comprised 30 patients (19 females, 11 males), with an initial age of 13.07 years [standard deviation (SD) = 1.3], treated with CHG and fixed orthodontic appliances for a mean period of 3...
