OBJECTIVE To assess the relationship between skeletal morphology and stress direction on the temporomandibular joint (TMJ) by a two-dimensional rigid body spring model (RBSM). DESIGN Lateral cephalograms were analyzed and the information was processed with a fortran analysis program. SETTING AND SAMPLE POPULATION The subjects were 149 patients (54 men and 95 women, mean age 21.8 +/- 5.9 yea...

BACKGROUND AND AIMS Class III malocclusions are considered as one of the most complex orthodontic problems to diagnose and treat. Numerous studies have been conducted to determine the morphologic characteristics of craniofacial complex in patients with this malocclusion. The aim of this study was to determine the dentofacial characteristics of Class III malocclusion in Mashhadian adults. MATE...

OBJECTIVE The aim of this study was to evaluate the mean rotation of the upper first molar (U1(st) M) in cast models from nontreated patients presenting: Class I, skeletal Class II, dental Class II, and skeletal Class III, comparing with Class I orthodontically treated patients. MATERIALS AND METHODS One hundred cast models were evaluated with five groups, composed of nontreated Class I (n = ...

A study was conducted to investigate the condylar path angle in relation to Angle's classification, amount of overbite and subjective symptoms. The condylar path angle in Angle's Class I group was similar to that in the Class II group. The angle in the Class III group was smaller than in the other two classes. A tendency for the angle to decrease as the amount of overbite became smaller was obs...

BACKGROUND/AIM In malocclusion of skeletal class III, mandible is located in front of maxilla in sagital plain, which is manifested by a lower value of the sagital inter-jaw angle than in skeletal class I, where the jaw sagital relation is normal. Apart from the deformities on mandible and/or maxilla, in skeletal class III deformities are also frequent on the cranial base. The aim of this resea...

OBJECTIVE To evaluate the relationship between head posture and anteroposterior skeletal patterns in female adult patients. METHODS The study included 75 lateral cephalograms of orthodontic patients in the age range of 18-25 years. The study was conducted from May 2012 to January 2013 at the College of Dentistry, King Saud University, Riyadh, Kingdom of Saudi Arabia. The lateral cephalograms ...

Objective: This study seeks to review current and relevant literature on global Angle class III malocclusion prevalence. Materials and Methods: The electronic databases PubMed, ISI Web of Knowledge, and the Cochrane Database of Systematic Review were searched using specific inclusion criteria to obtain applicable articles. All pertinent references were also examined for acceptability. Results: ...

objective: attempts to treat class ii malocclusions without extraction in non-compliant patients have led to utilization of intraoral molar distalizing appliances. the purpose of this study was to investigate dental and skeletal effects of bonded molar distalizer (bmd) which is a simple molar distalizing appliance. materials and methods: sixteen patients (12 girls, four boys) with bilateral hal...

OBJECTIVE To compare self-esteem scores in 12 to 16-year-old adolescents with different Angle malocclusion types in a Peruvian sample. MATERIAL AND METHODS A cross-sectional study was conducted in a sample of 276 adolescents (159, 52 and 65 with Angle Class I, II and III malocclusions, respectively) from Trujillo, Peru. Participants were asked to complete the Rosenberg Self-Esteem Scale (RSES...

Sınıf III maloklüzyonlar tedavi başarısı ve yüksek relaps riski nedeniyle zor anomalilerden biri olarak tanımlanır. Büyüme gelişim dönemi içerisinde yapılan sınıf maloklüzyonların tedavisi aynı dönemde diğer tedavilerine oranla daha zordur. Bunun yanı sıra geç mandibuler büyümeye bağlı sonuçları olumsuz etkilenebilmektedir. tedavilerinin başarılı olması stabil kalması, anomalinin dişsel/iskelet...
