Joint 3D prints stealthy impacted tooth draw gear who rescues ware of cooperation

Technical Field

The utility model relates to an apparatus for clinical use of orthodontics, in particular to a impacted tooth traction device of a combined 3D printed invisible coordination appliance.

Background

In the prior art, the traction of the impacted tooth is carried out by using the invisible appliance, particularly the traction of the impacted tooth with high inclination is very difficult because the invisible appliance mainly applies acting force by wrapping the whole dentition tooth surface, and the position of the impacted tooth is limited because the impacted tooth is positioned outside the dentition and the exposed surface of the dental crown, and the invisible appliance cannot form a wrapping, so the traction is difficult to be carried out by directly applying force through the appliance. Although the movement of the impacted tooth can be realized to a certain degree by adhering a traction force system formed by a temporary traction buckle and a traction buckle on the surface of the impacted tooth to an upper opening of the appliance or individual teeth, the traction force system can only be used for simple impacted teeth with lower positions or the later stage of the basic in-place traction of difficult impacted teeth because the traction force point on the invisible appliance is too low, and the traction of the high-position inclined impacted tooth is difficult to realize. In addition, the force application position and direction are not reasonably planned, and the force application point is selected and hidden on the orthodontic appliance or the tooth surface of the adjacent tooth through clinical observation, so that the normal movement of other teeth except the impacted tooth can be influenced by the reaction force in the force application process. This traction method has limited effectiveness, poor efficiency and increased clinical operation time.
