We performed an orthodontic treatment combined with mandibular distraction osteogenesis in a 15-year-old patient who wanted a correction of a chin deficiency and a protruding upper lip. The patient had an Angle Class II division 1 malocclusion with mandibular retrusion, a low mandibular plane angle, and scissors bite. First, a quad-helix appliance was applied to the mandibular dentition to corr...

BACKGROUND AND AIMS Malocclusion with its great hazardous effects seems to have become more prevalent in recent decades; therefore, the present study was carried out to assess the prevalence of different malocclusions among 13-15 year-old adolescents in Tabriz. MATERIALS AND METHODS The subjects in the present study consisted of 398 adolescents aged 13-15, who were randomly selected from 5 di...

facial deficiency or true mandibular prognathism are difficult to manage nonsurgically, particularly when a hyperdivergent mandibular growth pattern creates an anterior open bite. For the past 25 years, early growth modification of midfacial deficiency with expansion and facemask therapy has been the standard treatment for Class III malocclusions.1,2 A disadvantage of this ap proach is that it ...

Open bite has fascinated Orthodontics due to the difficulties regarding its treatment and maintenance of results. This anomaly has distinct characteristics that, in addition to the complexity of multiple etiological factors, have aesthetic and functional consequences. Within this etiological context, several types of mechanics have been used in open bite treatment, such as palatal crib, orthope...

Objectives Amelogenesis imperfecta (AI) comprises a clinically and genetically heterogeneous group of conditions that affects the dental enamel, occasionally in conjunction with other dental, oral, and extra oral tissues. The purpose of this case report was to describe the necessity of the multidisciplinary approaches taken to treat a young patient diagnosed with hypocalcified-type of amelogene...

AIM To prospectively evaluate the functional capacity of the masticatory musculature as a predictive variable in determining functional appliance treatment outcomes in Class II/1 malocclusion children. METHODS Twenty Class II/1 malocclusion children (11.4 ± 1.7 years) were treated with functional appliances during 1 year. Masseter muscle thickness and maximal molar bite force measurements, la...

Class III malocclusion associated with skeletal anterior open bite pattern in adults can be a challenging orthodontic problem, especially for the nonsurgical treatment. Conventionally, several treatment alternatives are available such as tooth extraction, molar intrusion, and absolute anchorage system or orthognathic surgical correction. Although correction with surgery may be the most effectiv...

Background Thalassemia is a group of congenital disorders which is characterized by a deficient synthesis of alfa or beta globulin chains in hemoglobin molecules. Due to the problems resulting from changes in face, especially in dento-maxillary regions, such patients require special attention regarding oral health. Thus in this study, we aimed to assess the dento-maxillofacial changes in Beta-t...

Some of the most perplexing problems that the restorative dentist is called upon to treat involve those of the Class II deep bite patient. Class II deep bites are usually hereditary or are problems associated with growth or habit. Others have developed during adult life as a result of posterior teeth being lost or worn own, with subsequent tooth drift. These patients usually display a significa...
