Void region coats light-cured resin binding agent, and upper and lower jaw retainer is separately fixed on upper lower jaw, permissible using the method
Obtain good retention, shorter patient is more applicable especially for clinical crown, can strengthen rectifying effect.
In the present invention, described upper and lower jaw retainer is respectively equipped with casting hook corresponding to first bicuspid cheek side.?
During rescuing, can be drawn between two hooks, prevent night patient from dehiscing to keep the upper and lower sound of baby talk to close during sleep
Pad is in interlocking state, affects rectifying effect.
In the present invention, the occlusion inclined-plane of described upper and lower tooth Occlusal pad is with 45-70 ° of angle interlocking.
The present invention is used for the appliance of mandibular retrusion, can be fixed in patient oral cavity, and retention is good, due to upper lower tooth
Mutual interlocking relation between Occlusal pad, can effectively rescue mandibular retrusion.Due to lower jaw retainer, can be fixed on lower jaw complete
Tooth, lower jaw can obtain enough anchorage abilities；In addition, traditional twin-block appliance only has lower jaw bicuspid and its before
Tooth do anchorage, during rescuing, Anchorage molar is inclination movement, and the Zhi Kangli being achieved in that is limited, and the lip of lower labial teeth is to inclining
Effect tiltedly can be led to undesirable；The present invention is fixed on the full tooth of lower jaw due to lower jaw retainer, and Anchorage molar is to move integrally, and is propping up
Drag aspect improves a lot, and the lip being simultaneously not result in lower labial teeth, to inclination, significantly improves the effect for the treatment of.The present invention
Appliance for mandibular retrusion is provided that good retention, needs the case expanding bow can obtain for the upper jaw during rescuing
The more preferable effect than traditional twinblock.
