Pliers clamps the operation handle of prefabricated dental crowns or directly pinches operation handle with hand, and another hand carries out the behaviour such as porcelain, colouring
Make, in operating process, porcelain powder and pigment etc. can uniformly upper porcelain and colourings.It will not be controlled due to dynamics unstable pre- so as to destroy
Corona processed.What the model or 3D for the stamp that need to be only produced when such prefabricated dental crowns make in modeling to clinic scanned
The shape addition operation handle of model and the part of flange, it is easy to operate；And after use, operation handle need to only be cut
It removes.Being provided with for flange slides beneficial to prevention clamping device from operation handle.
Further preferably：Corona body include towards the gums end of gum and away from gum occlusal end, gums end and
It is circumferential surface between occlusal end, operation handle, which is connected to, to be close on the circumferential surface at gums end.
Using the above structure, cut off the marking left after operation handle to be located at gums end, corona body is implanted into
Behind oral cavity, the marking that operation handle leaves can be covered by natural gum or covered in following process by artificial adopted gum, so as to
The aesthetics of artificial tooth is not interfered with.
Further preferably：Operation handle extends perpendicularly to circumferential surface.
Using the above structure, in the case where the sectional area of operation handle is certain, operation handle and week can be reduced to the greatest extent
Contact area between face in this way, after operation handle is cut off, can minimize the marking left.Also, such setting
It is also convenient for hand-held or is clamped using instrument, the stability of porcelain or process of painting in raising.
Further preferably：Operation handle is cylinder, and groove is offered in the circumferential direction of operation handle.
Using the above structure, the setting of groove, which facilitates, clamps operation handle with instrument, prevents clamping device from behaviour
Make to slide on handle, the stability of porcelain or process of painting in raising.
Further preferably：Groove is dovetail groove or V-groove.
Using the above structure, dovetail groove or V-groove can clamp clamping device all there are two inclined side wall, so as to
The fastness that is connected with groove of clamping device is improved, prevention clamping device slides from operation handle, porcelain or paints in raising
The stability of journey.
Further preferably：The inner surface of groove is equipped with anti-skidding salient point.
Using the above structure, being provided with for anti-skidding salient point occurs to slide relatively beneficial to prevention clamping device with groove, raising
The stability of upper porcelain or process of painting.
Further preferably：Operation handle is sheet.
Using the above structure, the operation handle of sheet is conducive to increase the contact area of hand and operation handle, is conducive to
Handheld operation, while the marking area that operation handle will not also left after cutting off is excessive.
Further preferably：Operation handle is sheet, and the sheet-like plane of operation handle is perpendicular to circumferential surface.
Using the above structure, the operation handle of sheet is conducive to increase the contact area of hand and operation handle, is conducive to
Handheld operation, while the marking area that operation handle will not also left after cutting off is excessive, operation handle is perpendicular to circumferential surface
Setting, in the case where the sectional area of operation handle is certain, the contact between operation handle and circumferential surface can be reduced to the greatest extent
Area in this way, after operation handle is cut off, can minimize the marking left.
Further preferably：The sheet-like plane of operation handle is equipped with anti-skid chequer.
Using the above structure, being provided with for anti-skid chequer occurs to slide relatively beneficial to prevention clamping device with operation handle, carries
The stability of porcelain or process of painting on height.
In conclusion the utility model has the advantages that：By setting operation handle on prefabricated dental crowns body,
Polished, paint, polish, in the sequence of operations such as glazing, it is only necessary to pliers clamp prefabricated dental crowns operation handle or
Person directly pinches operation handle with hand, and another hand carries out the operations such as porcelain, colouring, and in operating process, porcelain powder and pigment etc. can
To be uniformly painted on prefabricated dental crowns surface, due to dynamics shakiness will not be controlled to destroy prefabricated dental crowns.To operation handle
