The aim of this systematic review of the literature was to assess the scientific evidence on the efficiency of functional appliances in enhancing mandibular growth in Class II subjects. A literature survey was performed by applying the Medline database (Entrez PubMed). The survey covered the period from January 1966 to January 2005 and used the medical subject headings (MeSH). The following stu...

The purpose of this study was to determine the effect of the T4K, a prefabricated functional appliance, on the transverse and anterior-height dimensions of the maxillary and mandibular dental arches. Dimensions before and after treatment were measured on the sample, then, natural growth was subtracted from the treatment effects and compared with twice the error of the method. A clinically signi...

The present case report addresses the treatment of an Angle Class II malocclusion in an adult female patient, long face pattern, with posterior open bite and dental arches extremely expanded, due to previous treatment. The patient and parents rejection to a treatment with orthognathic surgery led to orthodontic camouflage of the skeletal discrepancies. This clinical case was presented to the Br...

OBJECTIVE The purpose of this study was to cephalometrically compare the skeletal and dentoalveolar effects in the treatment of Class II malocclusion with Pendulum and Jones jig appliances, followed by fixed corrective orthodontics, and to compare such effects to a control group. METHODS The sample was divided into three groups. Group 1: 18 patients treated with Pendulum, Group 2: 25 patients...

OBJECTIVES We evaluated the skeletal and dentoalveolar effects of the Forsus Fatigue Resistance Device (FRD) and the Twin Block appliance (TB) in comparison with nontreated controls in the treatment of patients with class II division 1 malocclusion. MATERIALS AND METHODS THIS RETROSPECTIVE STUDY INCLUDED THREE GROUPS: TB (n=37; mean age, 11.2 years), FRD (n=30; mean age, 12.9 years), and cont...

The identification of the skeletal maturation stage of the cervical vertebrae has proven an important reference for orthodontic diagnosis. The aim of the present study was to determine the association between the skeletal maturation stage of the cervical vertebrae and types of malocclusion according to the age and gender of participants. A total of 361 individuals (168 males and 193 females) be...

Introduction: Knowledge of the distribution of different malocclusions in a geographic location could help orthodontics better know the problems in that region. Moreover, giving awareness about the problem and treatment possibilities can help people. This study aimed to determine types of malocclusion and dental caries in children aged 11 to 14 years in Roudsar, Iran. Materials and Methods: In...

INTRODUCTION This article demonstrates the description and use of a new appliance for Class II correction. MATERIAL AND METHODS A case report of a 10-year 5 month-old girl who presented with a skeletally-based Class II division 1 malocclusion (ANB = 6.5°) on a slightly low-angle pattern, with ML-NSL angle of 30° and ML-NL angle of 22.5°. Overjet was increased (7 mm) and associated with a deep...
