Astudy of the effect of Sagital malocclusion at Class I and Class II on Facial Asymmetry at the Frontal Plane for a Sample of Patients Using Computed Tomography (CT)

The asymmetric face is common so that increased interest in it .there are different ways to assess the asymmetry. Computed tomography is an accurate way that enable the examiner for reading the face at three planes ,and present three-dimensional information on the cranial mandibular Complex whereas (3D) analysis is essential for making a precise diagnosis of craniofacial morphology. Aim : This research aims to study the asymmetric at the facial patterns malocclusion (class I. Class II) using CT . the research sample consists of 48 CT image (male 23 and female 15)their ages ranged between 18 and 35 years old and did not receive any orthodontic treatment before, and devided into two groups according to the malocclusion ptterns(17 class II, 31 class I ) . Analysis was performed T. student test then calculated for all the data obtained . This study showed that a significant difference between the class I and class II malocclusion in each of the right and left.

A Study of the Dental and Skeletal Features of the Anterior Open Bite in Permanent Occlusion in Syrian population in median region

The aim of This study was to identify the skeletal and dentoalveolar components in Syrian adult subjects whom have an anterior open bite by comparison with the normal occlusion subjects. This study showed elongation of upper and lower incisors, of upper molar height and increasing of anterior facial increasing height (P<0.05) in anterior open bite group compared with natural occlusion group .

Articular eminence Inclination and its relationship with incisors mesiodistal inclination in skeletal class I occlusion adults with no clinical and radiographic symptoms of TMDs

Articular eminence participates in the functional formation of the posterior guidance of the mandibular movement, it's the anatomical point where functional stresses can result in alteration of the contours of the articular eminence, and its inclination respectively, Hence, orthodontists need to know the relationship between the articular eminence Inclination and the mesiodistal inclination of upper and lower incisors to achieve more stable results of orthodontics treatment. Aim The aim of this research is to investigate the relationship of upper and lower incisors mesiodistal inclination with the inclination of the articular eminence in class I skeletal occlusion in adult subjects with no clinical nor radiographic symptoms of TMDs. Materials and methods: In result of radiographic study and a multistage clinical examination protocol, 46 Caucasian patients with no prior orthodontics treatment were selected (19 males, 27 females) from 16 to 27 years of age with skeletal class I occlusion and no clinical or radiographic signs and symptoms of TMDs. Furthermore, cephalometric evaluating of the Inclination of the articular eminence and the mesiodistal inclination of the incisors was performed; Pearson's Correlation Coefficient was calculated to investigate the relationship of articular eminence Inclination with the mesiodistal inclination of the incisors. Results: no significant relationship between incisors mesiodistal inclination and the articular eminence inclination was found. Conclusions the steepness of the articular eminence appears not to vary with mesiodistal inclination of the incisors in skeletal class I occlusion adults with no clinical and radiographic symptoms of TMDs
