A statistical correlation is found between the S-N/mandibular plane angle and clinical freeway space, but there was no correlation after TENS stimulation. The S-N/MP angle did not prove to be a reliable predictor of freeway space.
The authors describe a new program for cephalometric analysis which uses a commonly available microprocessor (computer) and digitizing pad to register fifteen commonly identified cephalometric landmarks to produce a meaningful analysis which is printed out for permanent or hard-copy record. Conventional and digitizing errors of cephalometric measurement are… (More)
