Study Overview
Brief Summary
This Prospective study aims to simulate the maximum mandibular advancement in class II patients treated by Herbst MTH Appliance on the base on clinical overjet.
Initial intraoral scans will be uploaded in Suresmile software, the upper incisors will be virtually aligned and the mandible will be advancement until an anterior occlusal contact will be reached. This virtual advancement will be compared to the real advancement obtained at the end of the Herbst phase.
This protocol will be applied to two groups: one with traditional dental occlusion, the second one with Skeletal anchorage reinforcement and elastic chains
