[Reproducible and congruent radiographs for the study of bone structure].
Radiograms that are reproducible and are as identical as possible are an absolute prerequisite for objective early diagnosis of the smallest changes in the bone structure. Changes that are no longer visible to the naked eye, are recorded by photometry and can be represented objectively by computerized evaluation. It is the object of this study to develop a method for taking roentgenograms with films generally used in the dental office, which allows to always the area always to be radiographed reproducibly. The x-ray machine is described and tested on four patients. The radiograms are photometrically scanned and entered into a computer in order to check the location of the radiograph. The results show that with our method it is possible to take identical radiograms at different times.
