[Interpretation of orthodontically treated by means of punched cards. 2. Data at the completion of treatment].
The authors analysed the key-word cards of 3245 terminated orthodontic cases. Statistical data were obtained about treatment results, therapeutical aids, duration of treatment and co-operation of the patients. These data give a survey on the achievements of the orthodontic practitioner, the choice of his methods and the utilization of his therapeutical aids. The authors could draw certain conclusions as to their own work in practice. Furthermore, they realized that the use of key-word cards permits to evaluate critically their achievements and to perform collective scientific studies.
