What is the recommended CT scan technique for a complete mandibular subperiosteal model?

The recommended CT scan technique for a complete mandibular subperiosteal model is to use 2-3 mm slices. This slice thickness provides a balance between spatial resolution and image noise, allowing for detailed visualization of anatomical structures while minimizing the volume of data that requires processing.

Using this slice thickness enables effective detection of critical features and anatomic variations within the mandible, which is especially important for surgical planning in implant dentistry. Thinner slices could yield superior detail but often lead to increased radiation exposure and larger datasets that can be cumbersome to analyze. Conversely, thicker slices might poorly represent smaller structures or finer details needed for accurate assessments. Thus, 2-3 mm slices are optimal for capturing the necessary detail without adding unnecessary risk or complexity.
