OBJECTIVE To test the accuracy of a mathematical model (algorithm) that corrects measurements made on conventional lateral head films to corresponding dimensions observed in a cone beam computed tomography (CBCT) scan in human subjects. MATERIALS AND METHODS Thirteen subjects had lateral cephalograms taken with a conventional cephalometric machine as well as a CBCT scan. Measurements of midfa...

statement of problem: some vertical changes might be observed during the first stage of orthodontic treatment, aligning and leveling. purpose: the aim of this study was to evaluate dental and/or skeletal vertical changes occurring in the first stage of preadjusted orthodontic treatment. materials and methods: fourteen patients with an average age of 14.1 years were selected for this study. prea...

PURPOSE The purpose of this study was to evaluate the accuracy of panoramic imaging in measuring the right and left gonial angles by comparing the measured angles with the angles determined using a lateral cephalogram of adult patients with class I malocclusion. MATERIALS AND METHODS The gonial angles of 50 class I malocclusion patients (25 males and 25 females; mean age: 23 years) were measu...

objective: since orthodontic and orthognathic treatment planningin each ethnic group must be done according to the soft tissue facial characteristicsregarded as beauty,they thus vary from country to country.the main purpose of this articlewas to determine the mean range of the middle third of soft tissue facial profile and anteroposterior lip positioningusing 3angular and 2 linear measurements ...

 Place Duration of Study: Armed Forces Institute Dentistry (AFID), Rawalpindi Pakistan, Feb 2017 to Nov 2018.
 Methodology: Sample size was ...

INTRODUCTION The aim of this study was to determine whether 2-dimensional (2D) images produced from cone-beam computed tomography (CBCT) images taken with an iCAT scanner (Imaging Sciences International, Hatfield, Pa) can substitute for traditional cephalograms. METHODS Lateral and frontal cephalograms were taken of a radiographic phantom with known dimensions. Landmarks on the 2D images were...
