Orthodontic treatment is considered successful only if optimal esthetic and
function are achieved.The objective of this study was to compare facial soft tissue profile changes
produced by a new technique (elastic forces based on skeletal anchorage
mini-plates) with changes
produced by conventional class-II elastic forces.
Success clinical attempts have been carried out to support fixed functional
appliances by using skeletal anchor plates placed in the symphysis to avoid mandibular incisors
protrusion.
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.
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 in
formation 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.
