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...

This case report describes the retreatment of a patient with a Class II Division 1 malocclusion; she had the same anteroposterior discrepancy after undergoing fixed appliance treatment with extraction of 4 first premolars.

The aim of this longitudinal study was to assess the relation between the transverse craniofacial dimensions of subjects with Class II, Division 1 malocclusion and the breathing mode presented by them. Forty Angle Class II, Division 1 malocclusion subjects of both genders participated in the study, 23 of which were predominantly nose breathers and 17 were predominantly mouth breathers. The mean...

INTRODUCTION Our objectives were to assess treatment outcomes in Class II Division 1 patients who were treated orthodontically with extraction of the maxillary first permanent molars and to describe the changes in their facial profiles. METHODS This was a prospective, longitudinal, 1-group outcome analysis in a private practice, with outcome evaluation by independent observers at an academic ...

This study has defined the cephalometric values of the Craniofacial Analysis of the Tweed Foundation for a sample of Brazilian subjects. The sample consisted of 211 cephalometric radiographs from subjects aged 12-15, which were divided into two groups: Class II group, with 168 lateral teleradiographs (cephalograms) of white Brazilian subjects, with Angle Class II, division 1 malocclusion, of bo...

This case report was submitted to the American Board of Orthodontics as part of the board-certification process. The summary of treatment and records are reprinted here much as they were submitted to the board.

Introduction: The Purpose of this study was to evaluate dentofacial vertical dimension alteration in patients with class II division 1 malocclusion after the first maxillarypremolar extraction. Methods:This study used 24 cephalogramseach before and after treatment. Dentofacial dimension measured by Sivakumar and Valiathan method. The cephalometric measurements investigated were as follows : man...

The patient was a 9 years and 2 months old female from the Dominican Republic whose chief complaint was, “My front teeth stick out.” The patient’s medical history was noncontributory, and she denied any known drug allergies. Her dental history revealed preventive dental visits at 6-month intervals and a fractured incisal edge (maxillary left central incisor). The patient’s mother reported the p...

To assess changes in bimaxillary morphology in patients with Class II division I malocclusion treated using Twin Block appliances (TBA), pre- and posttreatment lateral cephalographs of 100 patients seven to 16 years of age were compared. The patients were divided into four groups: (1) prepubertal boys (mean treatment time; 13.6+/-4.0 months), (2) adolescent boys (20.1+/-7.7 months), (3) prepube...
