Abstract
Embodiments of the present disclosure provide a sculpting and shaping tool for dental resin, comprising: a handle, a rotating assembly, and a sculpting and shaping tip. One end of the sculpting and shaping tip is coaxially and rotatably connected to one end of the handle through the rotating assembly. When in use, after a resin restorative material is filled in a carious cavity, the sculpting and shaping tip is placed on the resin restorative material. The handle moves to drive the sculpting and shaping tip to rotate, thereby rolling a surface of the resin restorative material. After rolling, the surface of the resin restorative material is smoother and free of protrusions, effectively preventing unevenness on the surface.

[0079]
[0080] In some embodiments, as shown in
[0081] The cutter tip 7 is a device configured to sculpt and shape a resin restorative material. The cutter tip 7 may include, but not limited to, a straight cutter, a curved cutter, a hook cutter, or the like.

[0083]
[0084] In some embodiments, as shown in
[0085] A usage manner of the sculpting and shaping tool for dental resin of the present disclosure is as follows: after the resin restorative material is filled into a carious cavity, the handle 1 is held and moved back and forth, thus driving the sculpting and shaping tip 3 to shape the resin restorative material by rolling back and forth on a surface of the resin restorative material. Further, when it is necessary to sculpt the resin restorative material, the cutter tip 7 at another end of the handle is used for sculpting.
[0086] In the sculpting and shaping tool for dental resin described in the present disclosure, the sculpting and shaping tip is coaxially and rotatably connected with the handle through the rotating assembly. When in use, after the resin restorative material is filled into the carious cavity, the sculpting and shaping tip is placed on the resin restorative material, and the handle is moved to drive the sculpting and shaping tip to rotate, so as to roll the surface of the resin restorative material. After rolling, the surface of the resin restorative material is smoother without protrusions, preventing unevenness on the surface of the resin restorative material.
