These methods can also be called indirect or direct method.

It can be achieved by two different ways: Through systems with or without the use of radiographic films. The concept of the digital radiographic image refers to the image obtained from X-rays incidence and displayed on the computer.

The use of both digital radiography and conversion of manual film to a digital format offers several advantages - it is easy to use, allows several analyses to be performed at a time, promises convenience when generating treatment predictions, takes up less storage space, allows superimposition of images, provides the option to manipulate the size, and contrast of the image and provides the ability to archive and improve access to images to overcome the problem of film deterioration, which has been a major source of informations loss in craniofacial biology. With the rapid evolution of computer radiography, digital tracing has slowly replaced the manual tracing methods. The use of computers in treatment planning is expected to reduce the incidence of personal errors due to operator fatigue and provide standardized, fast, and effective evaluation with a high rate of reproducibility. Reproducibility of measurements by the operator is also a significant factor in determining the accuracy of any method of analysis. Cephalometric errors can be divided into those related to the acquisition, identification, and technical measurement. However, despite its widespread use in orthodontics, the technique is time-consuming and has several drawbacks, including a high-risk of error in tracing, landmark identification, and measurement. The conventional cephalometric analysis is performed by tracing radiographic landmarks on acetate overlays and measuring linear and angular values. The digital evaluation of cephalometric analysis supplemented with two-dimensional profile photo of the patient provides an overview of changes caused by the therapy. The cephalometric analysis can be performed manually or by software. It is essential for correct treatment assessment and later for the evaluation of the therapy. In orthodontics, cephalograms are the crucial diagnostic component. Cephalometric norms were published by prominent clinicians and researchers, and are used for diagnosis, treatment progress, posttreatment evaluation, and research. Available from: ДЇor more than seven decades, cephalometry has been one of the main diagnostic tools available to the orthodontist. Comparison of conventional and digital cephalometric analysis: A pilot study.

Conclusion: According to this study, is reasonable to conclude that the manual and digital tracings show the statistically significant difference. (B) From McNamara analysis variables Nasolabial angle and L1-APog show statistically significant differences and the Mandibular length shows the statistically very significant difference. Results: (A) From Burstone analysis variables N-Pg II Hp show statistically very significant difference, and ANS-N, U1-NF, N-B II Hp, L1-Mp, and Go-Pg shows the statistically significant difference. Statistical significance was set at the P < 0.05 level of confidence.

A paired t-test was used to detect differences between the manual and digital methods.

Statistical analysis was undertaken using SPSS 17.0 version (Chicago, Illinois, USA) statistical software program. Data were subjected to statistical analysis. No differentiations were made for age or gender. McNamara analysis and Burstone hard tissue analysis were performed by both conventional and digital method. The radiographs were subsequently scanned and digitized using Dolphin Imaging software version 11.7. Materials and Methods: Conventional lateral cephalograms of 20 subjects were obtained and manually traced. Aim: The aim of the study was to analyze and compare the manual cephalometric tracings with computerized cephalometric tracings using Burstone hard tissue analysis and McNamara analysis.
