Methods Measurement of 11 dentalmodels was performed, midline of palate was defined as central line, the distance of every contact point to the midline was measured in each side.
CONCLUSION: Combination of 3-d finite-element model with spiral CT-cross technology establishes complex dentalmodels, simulates practical conditions authentically and is good in operation.
