发明名称 Narrow ceramic self-ligating orthodontic bracket
摘要 A ceramic orthodontic bracket has a centrally located clip for retaining an archwire in an archwire slot. The body of the bracket includes a mesial section, a distal section, and a bridge section, wherein the bridge section extends through, and retains, the clip. The bridge section also includes a recess adjacent to the bridge section that facilitates debonding of the bracket from a patient's tooth. Preferably there are gaps on one or both sides of the clip to allow space for debonding of the bracket by applying a mesial-distal compressive force on the bracket and fracturing the bracket along the recess. This configuration allows the overall mesial-distal width of the bracket to be reduced, thereby facilitating the bonding of brackets to narrow and/or maloccluded teeth. Another embodiment includes a stop member that is connected to the base of the bracket and retains the clip on the bridge section.
