Palatal and maxillary Arch width changes in patients with Class II division 1 malocclusion treated with maxillary first premolar extraction

Objective: The aim of this study was to determine palatal and maxillary arch width changes during MBT PEA with maxillary first premolars extraction treatment in patients with Class II division 1 malocclusion. Material and Methods: Dental casts of 24 Class II division 1 patients (8 males and 16 females) were evaluated. The minimum age of the subjects at the beginning of treatment was above 16 years with mean age 02.02± 2.82. All patients were treated with extraction of the maxillary first premolars and MBT PEA. Pre- and post-treatment maxillary and palatal (inter-canine and inter-molar) widths were measured using a digital calliper of 0.01 accuracy. Paired samples t-test was used to evaluate the treatment changes within total sample and within males group and females group. Differences between males and females were tested using independent samples t-test. Results: At the end of treatment, maxillary and palatal inter-canine widths increased significantly (P>0.001).The maxillary inter-molar width increased but the values were statistically insignificant (P<0.05). The palatal inter-molar width increased significantly (P>0.01). No significant differences were observed between males and females. Conclusions: Class II division 1 patients treated with extraction of maxillary first premolars had tendency for an increase in palatal and arch width during treatment except maxillary inter-molar width. It seems that a more thorough assessment and investigation including pretreatment arch shape and factors related to anchorage should be carried out.

Relationship between craniofacial morphology and cervical vertebral posture in patients with skeletal Class II malocclusion

The aim of this study was to investigate the relationship between cervical vertebral posture in patients with skeletal Class II malocclusion by using lateral cephalometric radiographs were taken by natural head position.

Relationship between craniocervical posture and skeletal patterns of malocclusion in the sagittal plane ( cephalometric study )

The Objective is to study the relation between craniocervical posture and skeletal patterns of malocclusion in the sagittal plane in adults , None of them had a history of previous orthodontic or orthognathic surgery treatment by using lateral cephalometric radiographs. our sample consisted of 71 adults patients; class I (n=21) , class II (n= 30 ) , class III (n=20 ) .All radiographes were taken in natural head position.

A study of the relationship between congenital hypodontia and skeletal malocclusion in a sample from the Syrian coast

This study aims to determine the skeletal problems in sagittal plane in patients with congenital hypodontia. In this study, 96 cephalograms were taken of Syrian coastal father and mother. The sample was divided according to gender and to location of the missing teeth. The angles SNA, SNB and ANB were studied.

The relationship between impacted mandibular third molar area morphology and mandibular length in adults with skeletal malocclusion in the sagittal plane

Impacted mandibular third molar area has been a topic of interest for a long time, and one of the most investigated parameters for two reasons:1- the lower third molars are the second most frequently impacted teeth[1,2 ]. 2- the lack of space is considered to be the major cause of this.so the radiographic diagnosis for this area is an important issue for orthodontists because of it's important role in mandibular third molar eruption wich play an impact on lower arch crowding and stability of orthodontic treatment. Objective:to study the relationship between impacted mandibular third molar area morphology and mandibular length in adults with skeletal malocclusion in the sagittal plane and to investigate the effect of sex on this area in these subjects by using cephalometric radiographic.

A study of prevalence of malocclusion in the three planes in sample of Syrian coast children in mixed dentition stage

Malocclusion is considered one of the most prevalent dental problems .This research aimed to study the prevalence of malocclusion states in the Syrian coast community. The sample of study consists of 1200 patients in mixed dentition stage (569 males – 631 females) with mean age (8.65 ± 1.4 years for male, 8.64 ±1.36 years for females). The study showed a prevalence of malocclusion in about 84.8% of the sample, with about 58.33% for vertical plane malocclusion and 84% for sagittal plane malocclusion, and 37.8% for transversal plane malocclusion. We concluded that it is very important to improve the hygiene awareness between our community population for better prevention and treatment of these problems.

Evaluation of the Efficacy of the Twin Block vs the Schwarz Double Plate in Skeletal Class II Correction: a Lateral Cephalometric Study

functional treatment of skeletal class II malocclusion is one of the most important treatment options in mixed dentition. The aim of this research is to evaluate the effectiveness of two of the most popular functional appliances in daily orthodontic practice which are: Schwarz double plate and twin block, and to compare the effectiveness of these appliances.

Dental anomalies study in the Orthodontics Syrian patients with Class I malocclusion (Retrospective study)

Dental anomalies are congenital defected teeth which have a certain prevalence in various malocclusions. the aim of this study was to determine the prevalence of different dental anomalies in Class I malocclusion patients seeking orthodontic treatment.

Skeletal and Dento -Alveolar Changes During Treatment of Class II Malocclusion with Fixed Appliances and Combined with the Distal Jet

Distalizition of the upper first Molar is a common treatment modality and very important method to correct Distal Malocclusion, or to create Spaces in the upper arch. The Distal Jet has recently been proposed to distalize maxillary molars in Class II cases with no need for patient cooperation.
