Interactive online program to improve cephalometric tracing skills.

Cephalometric analysis has a key role in orthodontic clinical practice and research. The skills needed to accurately trace radiographs can be acquired only through practice. We developed an interactive, Internet-based system to help students hone their cephalometric tracing skills. The online system allows students to practice any time and at their own pace, and receive immediate graphical feedback on the quality of their work. It also allows instructors to update the collection of cases available to students for practice.
