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: 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...

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...

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...

Aim: The aim of this study was to quantify secretory immunoglobulin A (S-IgA) in the saliva of children with type 1 diabetes, asthma, no systemic disease, and no systemic disease but wearing a removable orthodontic appliance. Methods: The study recruited 116 children who had either type 1 diabetes or asthma, were systemically healthy, or were systemically healthy but wore a removable orthodonti...

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...

A new modality of orthodontic treatment based on the thermoformed appliance was developed and trialled clinically. A light-cured resilient lining material commonly used for denture relining was placed locally and sequentially in thermoformed appliances to generate orthodontic forces. The new method appeared to be effective. All the presented cases showed substantial improvement in dental alignm...

Aim: The purpose of this study was to assess chlorhexidine effects on plaque index and salivary levels of mutans streptococci (MS) when used as the immersion solution for removable orthodontic appliances and added to their acrylic resin composition. Methods: Forty-five patients (6 to 12 years old) were randomly assigned into three groups with 15 patients each. Group I (control)—without orthodon...
