【Abstract】 Objective To establish the normal MESH diagrams of Chinese in Beijing,and to build a computerized MESH analysis system for orthodontic practice.Methods Twenty-eight subjects with normal occlusion were selected in Beijing and their lateral cephalograms were taken at the age of thirteen and eighteen,respectively.Individual MESH diagrams were then established for each subject mainly according to Moorrees′ method from the cephalograms orientated in estimated natural head position.Male and female normal MESH diagrams were created.A computerized MESH analysis system was also developed. Results The normal MESH diagrams of Chinese in Beijing,thirteen and eighteen years old respective,were established.The computerized MESH analysis system was constructed and used in orthodontic patients.Conclusions MESH analysis is a proportional analysis method.It can show the results directly,succinctly and holistically.It is also a favorable complement and amendment to the commonly used angle and linear X ray analysis methods.更多还原
