OBJECTIVE To assess self-esteem and depression in patients submitted for orthognathic surgery. METHODS Assessment was realized on 29 patients, male and female, aged 17 to 46, presenting Angle Class III malocclusion and referred for surgical treatment, during the preoperative (orthodontic preparation) and postoperative (six-month postoperative) periods. Either maxillomandibular or isolated pro...

INTRODUCTION The purpose of this study was to determine the skeletal, dental, and soft-tissue changes in response to camouflage Class III treatment. METHODS Thirty patients (average age, 12.4 + or - 1.0 years) with skeletal Class III malocclusions who completed comprehensive nonextraction orthodontic treatment were studied. Skeletal, dental, and soft-tissue changes were determined by using pu...

ABSTRACT
 Background: The aim of the present study was to evaluate craniocervical posture in adolescents with different malocclusions using a practical photographic analysis method. 
 Methods: Thirty-two (10-15 years) were recruited. subjects divided into three groups according Angle Classification as Class I (10 subjects), II (12 subjects) and III subjects). Craniocervical postural a...

BACKGROUND AND AIMS The oropharyngeal (OP) and nasopharyngeal structures seems to play roles in the development of the dentofacial complex. Soft palate as a part of nasopharyngeal and OP apparatus has an important role in phonation, deglutition and respiration. The aim of this study was to find whether any correlation exists between the three types of malocclusion and airway space using lateral...

The causal relationships between oral function and craniomandibular morphology are poorly understood. The aim of this study was to determine whether quantifiable features of masticatory jaw movements and associated EMG activity correlated with variation in morphology as defined by the ANB angle. Thirty-six healthy subjects with no previous orthodontic treatment, asymptomatic masticatory muscles...

By means of computer-based statistical methods, several types of Class II malocclusion have been discovered with defining horizontal and vertical characteristics. Of the six horizontal types, four are severe syndromes, one is a loose, ill-defined grouping of cases with mild skeletal features, and one has only the dental features of Class II. Five vertical types associates with Class II were als...

Sixty-nine experienced Chinese orthodontists evaluated 108 Chinese patients' facial attractiveness from set of photographs (frontal, lateral, and frontal smiling photos) taken at the end of orthodontic treatment. These 108 patients, which contained an equal number of patients with Class I, II, and III malocclusion, were randomly selected from 6 orthodontic treatment centers throughout China. Sp...

OBJECTIVES To successfully meet expectations on facial esthetics, it is important to understand normal craniofacial growth and the impact of orthodontic treatment thereon. To date, there have been few studies documenting changes in facial esthetics through photography. The objective of this study was to compare facial soft tissue esthetics before and after orthodontic treatment by means of phot...

background: functional appliances such as bionator have been used to treat class ii malocclusion. the purpose of this study was to compare the skeletal, dental and soft tissue effects of bionator appliances with multi-p (a newly developed appliance) in the treatment of class ii malocclusion. subjects and methods: 45 class ii children were chosen and randomly assigned to either the bionator or m...

As a novel performance, methanol gas conversion to dimethoxymethane (DMM) in one-step based on Fe-Mo-O (iron molybdate mixed oxides) catalysts with high surface area fabricated by metal organic frameworks (MOFs) precursors was improved. For this approach, at first, Fe(III) precursors (iron (III) 1,3,5-benzenetricarboxylate (MIL-100 (Fe) and iron terephthalate (MOF-...
