INTRODUCTION The cervical vertebrae maturation (CVM) method is used to determine the timing of treatment of Class II malocclusion. Because its performance has not been tested in patients with Class II, the objective of this study was to evaluate the effectiveness of the CVM method in predicting craniofacial growth in Class II malocclusion. METHODS Twenty-nine untreated girls with Class II mal...

AIM The main objective of any orthodontic treatment is to achieve well-established stable occlusal relationship with a definite positive change in facial profile. The purpose of this study was to determine, if such a goal is achievable for patients who could be classified as borderline surgical cases without the invasive use of the actual surgery or, with the use of the recently developed and r...

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...

BACKGROUND Few studies have focused on the impact of malocclusion on lip - tooth relationships during smiling and speech. AIM To evaluate the impact of different malocclusions on lip - tooth relationships during smiling and speech, using video images. METHODS One hundred and three subjects with Class I (N = 31), Class II division 1 (N = 26), Class II division 2 (N = 16) and Class III malocc...

BACKGROUND The purpose of this study was to compare the occlusal stability of class II subdivision malocclusion treatment with 3 and 4 first premolar extractions. A sample of 156 dental casts from 52 patients with class II subdivision malocclusion was divided into two groups according to the extraction protocol. Group 1 comprised 24 patients treated with 3 premolar extractions and group 2 inclu...

Background and Aim: The aim of the present study was to evaluate the cephalometric changes in Class II division 1 mandibular deficient patients treated with Farmand functional appliance.  Methods and Materials: Twenty-seven subjects (17 girls and 10 boys) with the mean age of 11.1±1.4 years were involved in the present study. All the subjects were treated with Farmand functional ...

The treatment of class II malocclusion during adolescence is an important challenge for orthodontists, moreover, if there are other growth factors that hinder the reaching of a normal occlusion. Maxillary molar distalization is an orthodontic treatment method that has obtained an important diffusion since last years for correcting pure dental Class II malocclusion. In the past, several applianc...

Two case reports illustrate the effective treatment of Class II division 2 malocclusion with modifications to the Twin Block appliance. This approach may reduce the total treatment time and reduce the need for extra-oral anchorage. In each of the cases presented treatment has been carried out on a non-extraction basis with full correction of the malocclusion.
