Mandibular Advancement Planning Based on Clinical Overjet
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

Treatment and study plan
mandibular advancement with acrylic splint Herbst Appliance
ProcedureMandibular advancement with acrylic splint Herbst Appliance
Primary outcomes
-
Planned mandibular advancement (mm)
Time frame: 1 year
The "planned mandibular advancement" will be evaluated on the STL of the arches by simulating a sagittal mandibular advancement , until an anterior occlusal contact will be reached
Secondary outcomes
-
Obtained mandibular advancement (mm)
Time frame: 1 year
The obtained mandibular advancement will be evaluated comparing the Sagittal position of the Pogonion (according to cephalometric pancherz's analysis) on the lateral ceph before and after the treatment
