Description
Technical field
This utility model relates to the dental appliance field, particularly a kind of appliance bracket and cheek pipe that is used for straightening of teeth.
Background technology
The existing appliance bracket that is used for straightening of teeth is to develop according to side's silk bow bracket development that U.S. Angle doctor before 80 years designs side's silk bow (Edgewise) appliance of invention, its groove is equal grooves of the side's of being silk bow classification in essence, and the width of groove (closing direction along gum) is less than the degree of depth of groove.After the orthodontic bow-wire of rectangular cross section entered groove, the narrower face of arch wire was parallel to the groove bottom surface, and the face of arch wire broad closes to inwall parallel with the groove gum.
After prior art is analyzed, the designer finds that there is following defective in the existing appliance bracket that is used for straightening of teeth: at first, the orthodontic bow-wire of rectangular cross section contacts with at the bottom of the groove with the narrower side, when needs apply torque to tooth, the arm of force of the bracket application of force is short, thereby the torque efficiency that applies is low.Secondly, owing to the degree of depth of groove width less than groove, thereby the frictional force between orthodontic bow-wire and groove is bigger, is unfavorable for the slip of orthodontic bow-wire.Once more, orthodontic bow-wire is with at the bottom of the narrower side contact groove, and it is poor that the side contact groove sidewall of broad, thereby orthodontic bow-wire increases at the thickness of tooth labial surface, this appliance are fixed on the tooth back comfort.
The existing appliance cheek pipe that is used for straightening of teeth all includes a hollow pipe that is used to pass the orthodontic bow-wire of rectangular cross section.In the inwall of this hollow pipe, cheek-tongue direction length is closed to length greater than gum.After prior art is analyzed, the designer finds that there is following defective in the existing appliance cheek pipe that is used for straightening of teeth: at first, the orthodontic bow-wire of rectangular cross section contacts with the side inwall that the narrower side and hollow pipe are parallel to cheek tube bottom plate direction, when needs apply torque to tooth, the arm of force of the cheek pipe application of force is short, thereby the torque efficiency that applies is low.Secondly, orthodontic bow-wire contacts with the side inwall that the narrower side and hollow pipe are parallel to cheek tube bottom plate direction, the side of broad is perpendicular to cheek tube bottom plate direction, thereby arch wire increases at the thickness of tooth labial surface, and it is poor that this appliance is fixed on the tooth back comfort.
The utility model content
This utility model embodiment provides a kind of appliance bracket and cheek pipe that is used for straightening of teeth.Described technical scheme is as follows:
A kind of appliance bracket that is used for straightening of teeth, comprise: the bracket base that fits with tooth, be located at the bracket body on the described bracket base and be located at the intrinsic groove of bracket, described groove deviates from a side opening of described bracket base, side near described bracket base is the bottom of described groove, and the gum of the bottom of described groove closes to the cheek-tongue direction degree of depth of width greater than described groove.
Further, it is the 0.026-0.028 inch that the gum of the bottom of described groove closes to width, and the cheek-tongue direction degree of depth of described groove is the 0.020-0.022 inch.
Perhaps to close to width be the 0.023-0.025 inch to the gum of the bottom of described groove, and the cheek-tongue direction degree of depth of described groove is the 0.017-0.020 inch.
The appliance bracket advantage that is used for straightening of teeth of the present utility model is as follows: the orthodontic bow-wire of rectangular cross section enters groove in the mode of band shape bow, helps tooth is applied torque force; Simultaneously the width of bracket groove is greater than the width of existing side silk bow and straight silk bow supporting groove groove, increased the area bottom the groove, reduced the pressure of orthodontic bow-wire to tooth, thus Srilane with; The width of bracket groove also helps the slip of arch wire in groove greater than the width of existing side's silk bow and straight silk bow supporting groove groove; At the bottom of the face contact groove of the orthodontic bow-wire of rectangular cross section with broad, then the words of arch wire are to thinner thickness, and patient's oral sensation is more comfortable.
This utility model embodiment also provides a kind of appliance cheek pipe that is used for straightening of teeth, comprising: the cheek tube bottom plate that fits with tooth and be located at hollow pipe on the described cheek tube bottom plate, in the inwall of described hollow pipe, gum closes to width greater than the cheek-tongue direction height.
Further, in the inwall of described hollow pipe, it is the 0.026-0.028 inch that gum closes to width, and the cheek-tongue direction height is the 0.020-0.022 inch.
Perhaps, in the inwall of described hollow pipe, it is the 0.023-0.025 inch that gum closes to width, and the cheek-tongue direction height is the 0.017-0.020 inch.
In this utility model, the orthodontic bow-wire of rectangular cross section penetrates hollow pipe in the mode of band shape bow, helps tooth is applied torque force; Simultaneously the gum of hollow pipe inwall closes to the gum of width greater than the hollow pipe inwall of existing cheek pipe and closes to width, has reduced the pressure of orthodontic bow-wire to tooth, thus Srilane and; Hollow pipe is with the face contact cheek tube bottom plate of broad, and then the words of hollow pipe are to thinner thickness, and patient's oral sensation is more comfortable.
