OBJECTIVE To use published data to evaluate quantitatively the dental effects of noncompliance intramaxillary appliances in individuals with Class II malocclusion. MATERIALS AND METHODS A literature search was carried out identifing 13 prospective or retrospective clinical studies matching inclusion criteria. Only appliances with conventional anchorage designs were considered for the review. ...

background: the extraction of teeth for orthodontic purpose has always been a controversial subject in the speciality. the aesthetics impact of the soft-tissue profile might play a key role in deciding on premolar extraction or non-extraction (ne) treatment, particularly in borderline patients. the purpose of this cephalometric study was to examine the soft-tissue treatment effects of class ii ...

OBJECTIVE The aim of this study was to cephalometrically assess the skeletal and dentoalveolar effects of Class II malocclusion treatment performed with the Jones Jig appliance followed by fixed appliances. METHODS The sample comprised 25 patients with Class II malocclusion treated with the Jones Jig appliance followed by fixed appliances, at a mean initial age of 12.90 years old. The mean ti...

Class II malocclusion is one of the most common orthodontic problems in our population, and the most consistent diagnostic finding is mandibular skeletal retrusion. There are many treatment approaches for the correction of this malocclusion with varying degrees of scientific support. In the last twenty years, functional appliances were widely used for correction of sagittal intermaxillary relat...

The present study aimed to evaluate the cephalometric changes in Class II patients treated exclusively with cervical headgear (CHG) in the maxillary arch and fixed appliances in the mandibular arch as compared with a control group. The sample comprised 82 lateral cephalograms obtained pre- (T1) and post- (T2) treatment/observation of 41 subjects, divided into two groups: group 1-25 Class II div...

BACKGROUND To evaluate skeletal and dentoalveolar effects of Forsus fatigue resistant devices (FRD) and twin-block (TB) appliance in Class II malocclusion cases. MATERIALS AND METHODS Twenty young adult patients (age 13-17 years, overjet 6-10 mm) with a Class II division 1 malocclusion were randomly divided into two groups: group I included 10 patients treated with TB, Group II included 10 pa...

OBJECTIVE To compare dentoalveolar and skeletal changes produced by the pendulum appliance (PA) and the distal screw appliance (DS) in Class II patients. METHODS Forty-three patients (19 men, 24 women) with Class II malocclusion were retrospectively selected for the study. Twenty-four patients (mean age, 12.2 ± 1.5 years) were treated with the PA, and 19 patients (mean age, 11.3 ± 1.9 years) ...

In Class II malocclusion, a variety of treatment modalities have been presented in the literature. The camouflage orthodontic is a treatment alternative, involving extraction of premolars. In the absence of an important mandibular crowding, the interdental relations can be obtained by numerical reduction in the upper arch, resulting in a Class II molar and a Class I canine relationship. It is i...

AIM To evaluate the dentoskeletal effects produced by Fränkel-2 (FR-2) appliance during the treatment of patients with Class II malocclusion by mandibular retrusion and to verify the long-term stability of these changes. MATERIALS AND METHODS Pre-treatment, post-treatment and long-term serial cephalograms (at least 10 years after the end of treatment) of patients treated with FR-2 were comp...

The purpose of this investigation was to compare the dentoalveolar and skeletal cephalometric changes produced by the Fränkel (FR-2) and bionator appliances in persons with Class II malocclusion. Lateral cephalograms were available for 66 patients of both sexes, who were divided into 3 groups of 22. The control group included untreated Class II children, with an initial mean age of 8 years 7 mo...
