overjet การใช้

• Prognathism is less prevalent in East Asians and retrognathia ( reverse overjet ).
• Management of appliance includes measuring overjet every appointment to measure the anchorage loss of the appliance.
• Its purpose is to slow or stop the upper jaw from growing, thereby preventing or correcting an overjet.
• Anchorage loss occurs as anterior teeth move mesially, shown by 2mm increase in overjet and also 1st molars moving mesially.
• Buckteeth, also called an overbite or overjet, is a condition that occurs when the top teeth protrude too far over the bottom teeth.
• They have an underdeveloped upper jaw, relatively protruding lower jaw with anterior mandibular vertical excess and a Class III skeletal and dental ( reverse overjet ) profile.
• Cases in which the Pre-Eruption Guidance process would be beneficial include improvement of dental alignment and correction of a functional occlusion ( severe deep bite, severe overjet, constricted maxillary width, blocked out maxillary cuspids, lower crowding ).
