Lateral scanned cephalogram
were evaluated twice by the same researcher with an interval of one week difference.
Regarding image diagnosis, a lateral cephalogram
is part of early orthodontic documentation, and its assessment has allowed orthodontists to observe possible upper airway obstructions.
To evaluate the stage of skeletal maturation of each cephalogram
according to the method described by Hassel and Farman.
The lateral cephalogram
was digitized in the University of Manchester, Department of Orthodontics, using an IBM[R]-compatible computer.
Each lateral cephalogram
was traced on 8 x 10 inch standard translucent acetate tracing paper, over a standard illuminated view box with a fine-point lead pencil (0.5 mm) and following measurements were done as defined in Table 1.
Periapical radiographs of the canines and first molars and lateral cephalogram
were obtained before and after the distraction procedure to measure the amount of retraction achieved during distraction.
20 landmarks were marked on each cephalogram
and 15 parameters indicating skeletal, dental and soft tissue parameters were selected and measured (Table 1).
Material and Methods: Fifty patients between 11-14 years of age were recruited having cervical maturation (CVM) stage 3 as diagnosed by their lateral cephalogram
. Only Skeletal class II patients as confirmed by ANB values of >4 and SNB values of <78 having low angle (SN-MP) are included in this study.

Cephalometrically, the patient had a similar dental and facial pattern to that in the beginning of the treatment, as observed in the posttreatment cephalogram
and the superimposition (Figures 2b, 2c; Table 1).
Subsequently, the lateral cephalogram
was used to determine the selection criteria for ordering a corrected lateral tomogram of the TMJ , to investigate the possible association between the joint structure and condylar position and craniofacial morphology , and to measure the TMJ positions of Malays and Chinese with facial asymmetry for assessing its impact on the temporomandibular disorders .
