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...

AIM Removable appliances are a dependable choice for many patients but like all orthodontic appliances, they have some limitations in use. Patient selection and appropriate appliance design are two key factors for success. Many patients, especially adults, prefer intra-oral appliances to extra-oral devices. Sometimes a removable intra-oral appliance can solve a dental problem in a shorter perio...

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...

Introduction: Nowadays, removable orthodontic appliances are widely used in the treatment of straightening teeth and guided the growth of the jaws. These devices have acrylic parts in which methyl methacrylate monomers are used and have been the subject of discussion in recent years as a cause of epithelial lesions in the oral cavity, and they are considered as one of the factors in mucosal al...

Objectives Tooth rotation is one of the most prevalent dental anomalies. Early management of rotated teeth would prevent possible occlusal interferences. The purpose of this case report was to introduce a fixed-removable appliance, which can efficiently correct severely rotated anterior teeth in a short duration of time in mixed dentition period. Case A 7-year-old boy with a Class I malocclusi...

several appliances have been used for palatal expansion for treatment of posterior cross bite. the purpose of this study was to evaluate the stress induced in the apical and crestal alveolar bone and the pattern of tooth displacement following expansion via removable expansion plates or fixed-banded palatal expander using the finite element method (fem) analysis.two 3d fem models were designed ...

The correction of posterior crossbites is more complex than it appears. To develop an appropriate treatment plan, it is first necessary to determine if: (1) there is a functional jaw shift on closing; (2) the crossbite is unilateral or bilateral; (3) it is dental, skeletal, or a combination of both; and (4) it is related only to the maxilla or both jaws. Once the problem's apparent cause has be...

Maxillary central incisors impaction is a challenging problem in orthodontics, which has a major effect on dental and facial esthetics. Scientific literature agree on the importance of early diagnosis and appropriate intervention. This is a case report of a 10 year-old boy who presented with impaction of maxillary central incisor related to previous trauma to primary dentition and apparent spac...
