The long-term effects of maxillary expansion on soft-tissues have not been well established. This presentation will answer the following questions: What are the effects of conventional and mini-screw assisted rapid palatal expansion on the soft-tissues in the long-term? Do the conventional rapid palatal expansion and mini-screw assisted rapid palatal expansion affect the soft-tissues in a different manner? This lecture would describe a cutting-edge technique of voxel-based superimposition of serial CBCT scans to analyze the changes with conventional and mini-screw assisted rapid palatal expansion as compared to controls. Furthermore, in this lecture, the short-term outcomes and long-term outcomes following expansion appliances would be described using color coded maps as well as the movement of points in coordinates in x, y, and z-axis
Learning Objectives:
After this session, attendees will be able to:
Show that the short-term and long-term outcomes with expansion appliances are different.
Demonstrate that the soft-tissue changes with conventional and mini-screw assisted rapid palatal expansion with color coded maps and movement of points in coordinates in 3 planes x, y, and z-axis.
Illustrate that in the long-term the changes with conventional and mini-screw assisted rapid palatal expansion are not significantly different than controls.
