A thorough and accurate diagnosis of a Class II malocclusion is essential before devising the treatment plans for aligners. In addition, the mandibular growth potential is key in determining the appropriate Class II mechanics of choice. In this lecture four types of Class II mechanics designs, consisting of Class II elastics, IZC screws, mandibular advancement(MA) devices and MA with IZC screws will be presented to help clinicians create a reasonable treatment plan.
Learning Objectives:
After this lecture, attendees will be able to:
Perform differential diagnosis on Class II malocclusion.
Design four types of efficient Class II mechanics with one or more of the following tools, including Class II elastics, IZC screws and mandibular advancement(MA) devices.
