Abstract
A longitudinal study of bone changes in the mandible was conducted. Duplicate radiographs were taken at 3-month intevals with the use of a positioning instrument, which included an aluminum calibrating wedge. The in-duplicate values obtained over the investigation period made it possible to assess the precision of the method and to analyze effects that take place with time. Significant bone changes were observed in seven volunteers between various observation periods at intervals of 6 and 9 months.
