Abstract [Purpose] To develop a digital radiographic bone trabecular structure analyzing system and to applied it to mandible. [Methods] Structural change was simulated by removing spongy bone in human dried mandible. Using a morphological filter processing, the skeletal features were extracted from digital radiographic image data obtained by computed radiography before and after the removal of spongy bone. The skeletal volume, surface, thickness, number, separation, complexity, spacing continuity and connectivity on the skeletal binary images were determined by morphometric indices calculation, star volume analysis and node‐strut analysis. Using these quantified skeletal feature parameters, a mapping sheet for the structural evaluation was produced. The correlation between the fluctuation rate of each parameter after the removal of spongy bone with respect to the value before the removal of spongy bone and simulated structural change was examined. [Results] The skeletal binary image data quantified sixteen skeletal feature parameters using morphometric indices calculation, star volume analysis and node‐strut analysis. These parameters agreed with the theoretical fluctuation pattern in the simulated skeletal structure deterioration of the mandibular bone trabeculae. [Conclusion] Using a morphological filter and bone histomorphometry, the radiological bonemorphometric analyzing system is useful for the evaluation of the mandibular trabecular structure.
