Embodiment 1

[0023] like Figure 1-3 shown.

[0024] A fixed denture temporary crown extracting pliers, comprising a handle 1, a hinge shaft 2 and a pliers beak 3, two opposite concave pads are provided on the inner side of the pliers beak 3.

[0025] The shape of the concave spacer 4 is an elliptical column, and the projection shape of the concave spacer 4 on the inner side of the beak 3 is ellipse.

[0026] The major axis length a of the elliptical projection of the concave pad 4 on the inner side of the pliers beak 3: 5mm, the horizontal axis length b perpendicular to the major axis: 4mm, the near pincer beak of the ellipse cylindrical concave pad 4 3 The height h1 of the front side: 0.5mm, the height h2 of the side near the hinge axis 2 of the elliptical cylindrical concave pad 4: 0.2mm.

Embodiment 2

[0028] A fixed denture temporary crown extracting forceps as described in Example 1, the difference is that the upper surface of the concave spacer is provided with a sawtooth structure 5 that increases friction.

Embodiment 3

[0030] A method of using the temporary crown taking pliers as described in Embodiment 1 and 2 includes the following steps: First, two parts on the buccal and lingual sides of the temporary crown can be processed respectively at the high points of the temporary crown taking crown pliers. The recessed spacer with the raised protrusions is suitable for the size of the groove; secondly, clamp the concave spacer with the protrusions of the temporary crown-taking forceps into the area with grooves on the buccal and lingual side of the temporary crown to realize the adjustment of the temporary Crown removal.

[0031] Put the temporary restoration material into the prepared temporary crown after mixing, quickly place it on the prepared abutment tooth, and remove it with crown pliers before the material is completely solidified, so as not to damage the relined crown edge, trim and adjust the occlusion , after trimming the crown edge, after reconciling the temporary restoration materia...

Abstract

The invention relates to a temporary crown taking crown forceps of a fixed partial denture, comprising a forceps handle, a hinged shaft and a forceps opening. The temporary crown-taking crown forceps is characterized in that two opposite concave cushion blocks are convexly arranged at the inner side of the forceps opening. The invention further relates to an application method of the temporary crown-taking crown forceps. The application method comprises the following steps of: firstly, respectively machining two grooves which are adapted to the concave cushion blocks convexly arranged on the temporary crown taking crown forceps on outer-shape high-point parts of the two sides of a cheek tongue of a temporary crown; and secondly, clamping the concave cushion blocks convexly arranged on the temporary crown taking crown forceps into a region at a cheek tongue side of the temporary crown, which is provided with the groove, so as to detach the temporary crown. When the temporary crown taking crown forceps of the fixed partial denture disclosed by the invention is used for taking the temporary crown, the defect of damaging the adaptation of the edge of the crow when the existing crown taking device is used for taking the crown is avoided and relining is not needed, so that the operation difficulty of a dentist and the hospitalizing time of a patient are greatly reduced, and the actual application value is higher.
