أجريت هذه الدراسة بهدف تحري دقة القياس و التأكد من وجود اختلافات في القياسات الخطية و الزاوية للمركب القحفي الوجهي بين طريقتي قياس ثنائية و ثلاثية الأبعاد لدى مرضى ذوي أنواع مختلفة من سوء الإطباق و مقارنة القياسات بين أنواع سوء الإطباق. تألفت العينة من 40 مريضاً حيث أجريت لهم صور طبقي محوري ثلاثي الأبعاد بالحزمة المخروطية CBCT و تم اشتقاق صور ثنائية الأبعاد و قسموا الى ثلاث مجموعات لسوء الإطباق الهيكلي ثم أجريت قياسات على تلك الصور و تم الحصول على النتائج و تحليلها إحصائياً.
This study was carried out aiming to investigate the accuracy of measurements , differences in linear and angular measurements of the craniofacial complex using both the two and three dimensional method of measuring in patients with different kinds of malocclusion ; and also to compare each kind of malocclusion to the others. The sample of the study consisted of 40 patients , divided into three groups – a group for each skeletal malocclusion , Cone Bean Computed Tomography (CBCT) was performed for each patient , then two dimensional radiographs were derived from the CBCT ; after performing the measuring , collecting the results and analyzing them statistically.

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.
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 III) using CT .

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.
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.
Individuals with dental crowding are the most frequent patients in
the orthodontic clinic. Therefore, it is useful to know the
contributing factors of dental crowding for planning of orthodontic
treatment and achieving stability and retention.
Th
e aim the study. Was studying effect of teeth sizes and linear
and angular dental Measurements on mandibular anterior
crowding in the early stage of mixed dentition.
