BACKGROUND: Extraction of premolars and retracting the anterior teeth using mini-implants and anterior retraction hooks became advent now a day. In such treatments, consolidation of arches is not done in regular practice. So, the present study is concentrated on effects of consolidation in two implant and three implant combinations of retraction and intrusion. METHODS: A three-dimensional FEM model of maxillary teeth and periodontal ligament housed in the alveolar bone with the first premolars extracted is generated with appropriate number of elements and nodes...

BACKGROUNDS: This article reports C-tube miniplates as a practical temporary anchorage device choice to treat open bite patients with maxillary sinus pneumatization. METHODS: The C-tube components are titanium anchor plates and monocortical screws that are basically similar to any other miniplate systems, but it has the unique characteristic of the tube head to be malleable. The manipulation of the head part is easy due to the composition of pure titanium. The I-shaped C-tube with 3 holes and T-shaped C-tube miniplates were placed above the apices of maxillary molars as an absolute anchorage system to intrude the posterior maxilla...

INTRODUCTION: Orthodontic treatment is a fundamental tool when approaching in a multidisciplinary manner a prosthetic rehabilitation, thanks to the possibility to place in an ideal position the involved teeth and to improve or even correct any periodontal defects. Several orthodontic tricks and version have been developed to limit as much as possible orthodontic appliances extension and treatment duration. However, it is not always easy to control teeth movements and manage anchorage when only few teeth are involved...

A girl, aged 11 years 4 months, with a skeletal Class II pattern and a severe overjet (10 mm) was treated with a Twin-block appliance. After 9 months of appliance therapy, the skeletal Class II was overcorrected. After 26 months of retention, when the occlusion was stable and the growth rate was diminishing, fixed orthodontic appliances using temporary skeletal anchorage devices were initiated. The total active treatment time with fixed orthodontic appliances was 30 months. Posttreatment records after 18 months demonstrated excellent stability: a functional occlusion and a pleasing facial balance...

The patient in this case is an 11-year-old girl, whose mandibular left canine was transmigrated. The traction to the arch was assisted by using a temporary skeletal anchorage device. After 5 months of poor response to traction, the biomechanics were re-adjusted, obtaining effective traction in to the arch in 12 months. After this period, the treatment was completed with fixed orthodontic appliances.

INTRODUCTION: When the mandibular permanent second molar becomes impacted, it is identified as a malocclusion that needs treatment as it often leads to unwanted complications such as caries and periodontitis of the adjacent permanent first molar. Other less common complications include root resorption of the adjacent first molar root or continued root development to be in close proximity to the inferior dental alveolar nerve. MATERIALS AND METHODS: This paper seeks to differentiate various levels of severity of impaction and review treatment options that are considered clinically available for the proper management of the impacted mandibular permanent second molar...

INTRODUCTION: The mini-implant, temporary anchorage devices (TADS), are now a common method of treatment in Orthodontics with versatility, minimal invasiveness and the relationship between costs and benefits that they offer even today. Skeletal anchorage has, to a large degree, replaced conventional anchorage in situations where anchorage is considered either critical, insufficient, or likely to result in undesirable side effects such as vertical displacements generated by inter-maxillary force systems...

BACKGROUND: Stability is determined as one of the requirements in use of Temporary Anchorage Devices (TAD) in orthodontics. Miniscrew has been a widely used Bone Anchor. Compared with mini-implant that necessitates osseointegration; mechanical retention is a determining factor for primary stability of miniscrew. Studies investigated various ways to increase primary stability. The aim of this study is to introduce a new configuration of miniscrew system which is believed to obtain more primary stability...

An anterior open bite is one of the most difficult occlusal abnormalities to treat. Quite often this aberration entails dental component and/or skeletal component. The skeletal open bite will require intrusion of the posterior sextants with the assistance of bite blocks, temporary anchorage devices, high pull headgear, and as a last resort - orthognathic surgery. The orthodontic treatment should be augmented with the orofacial myofunctional therapy. In this article, the author describes 3 different variations of treatment of the dental anterior open bite, first on acrylic models, and then on the actual patients...

A 15-year-old girl who had a unilateral condylar fracture with severe crowding in both arches was treated with 4 premolar extractions followed by orthodontic therapy with a temporary skeletal anchorage device in the maxillary arch. The total active treatment time was 21 months. Her occlusion was significantly improved by orthodontic treatment, and the range of condylar movement was also improved. Posttreatment records after 30 months showed excellent results with a good stable occlusion. The remodeling process of the condyle was confirmed with cone-beam computed tomography images...

A woman was referred to the orthodontic clinic for treatment. She was diagnosed with a skeletal Class II malocclusion, a steep mandibular plane, and an anterior open bite. Conventional orthodontic treatment was considered to correct the maxillary protrusion and anterior open bite, but the patient also requested improvement of her facial esthetics. We therefore decided that nonsurgical treatment consisting of 4 premolar extractions combined with temporary anchorage devices was indicated. Satisfactory improvement of the overjet and overbite, and proper functional occlusion were obtained, resulting in a Class I molar relationship...

Asymmetries are among the most challenging problems in orthodontics. Proper diagnosis is critical to discern first whether the asymmetry is dental or skeletal. If it is dental, one must then determine whether one dental arch or both are at fault. Once diagnosed, the next challenge is determining not only an appropriate treatment plan, but also the appropriate mechanics plan. This aim of this article is to present a patient with a severe asymmetry to emphasize the importance of a problem-based differential diagnosis to develop both a sound treatment plan and a mechanics plan that successfully integrates miniscrews from the start of the process...

A 45-year-old woman presented with an anterior open-bite complaining chiefly of her unpleasant smile esthetics and masticatory and speech problems. Treatment included speech therapy initiated immediately after bonding. Lingual spurs were positioned on the mandibular incisors in order to help tongue rehabilitation. During the working phase, temporary anchorage devices (TADs) were used at the mandibular anterior segment to intrude the lower left premolars. A splint was used to ensure retention in the upper and lower arches; an enveloppe linguale nocturne (ELN) was provided...

Extra-oral appliances are used in orthodontics to apply forces to the jaws, dentition or both and the popularity of these appliances is cyclical. Although the use of retraction headgear for the management of Class II malocclusion has declined over the last 20 years with the refinement of non-compliance approaches, including temporary anchorage devices, headgear still has a useful role in orthodontics. The use of protraction headgear has increased as more evidence of its effectiveness for the treatment of Class lIl malocclusion has become available...
