Abstract
The invention provides a back tooth crown removing clamp and a method for operating crown prosthesis after crown removal. The back tooth crown removing clamp is composed of a clamp beak, a joint, a clamp handle, and a spring. The clamp beak is vertically arranged on the top end of the clamp handle. The joint is arranged on the clamp handle and is close to the clamp beak. The whole crown removing clamp has a back clamping design. The clamp beak is composed of a left clamp beak and a right clamp beak, which are symmetrically arranged. The upper end of the left clamp beak is in a triangular shape, and the lower part is in a rectangular shape. The (a) edge of the triangle is vertical, the included angle between the (b) edge and the horizontal plane is 10 degrees, and the included angle between the (b) edge and the (c) edge is 45 degrees. The provided method for operating crown prosthesis after crown removal is simple, the grinding amount is little, the removal time is largely shortened, at the same time, no impact force or torsion force is loaded on the base teeth, and the discomfort feeling for patients is relieved.
Description
Technical field
The invention belongs to field of oral cavity medical equipment, a kind of method of corona dummy after particularly relating to backteeth crown removing pliers and utilizing it to remove.
Background technology
For being preced with the dismounting of dummy, currently mainly there are two kinds of demolition device tools.One is impact type demolition device.Using method is: uses corundum car pin mill shredding solution groove at hat buccal aspect or tongue side, releases the constraint of hat side, demolition device tip is hooked hat edge, slip impact type demolition device rear portion sliding hammer, makes hat dummy dislocate from abutment by impulsive force.Its shortcoming is: groove of 1, loosening preparation hat removing amount is relatively big, particularly cast crown；2, impulsive force is big on abutment impact, and patient's sense of discomfort is more apparent；3, for the hat dummy that the edge goodness of fit is high, demolition device is more difficult hooks hat edge；4, for adaptation height, hat dummy that Metal Substrate base thickness, retention are strong, it is more difficult to remove.Another kind is torsion formula demolition device.Using method is: closes face corundum colyliform car pin fluting at hat dummy tooth, by adhesive layer in the insertion groove of torsion formula demolition device tip, reverses hand holding handle, makes tip produce wedging forces, make hat dislocate.Shortcoming is that abutment is produced certain twisting resistance, and patient has a certain degree of sense of discomfort, especially agomphiasis.
Summary of the invention
Solve the technical problem that:The shortcoming that apparatus and method used by hat dummy exist is removed for existing, the present invention a kind of backteeth crown removing pliers is provided and utilizes it to remove after the method for corona dummy, this backteeth crown removing pliers can improve dismounting efficiency, reduces the damage to abutment, alleviates the sense of discomfort of patient.
Technical scheme:A kind of backteeth crown removing pliers, this backteeth crown removing pliers by clamping beak, joint, clamp handle, spring form, described pincers beak is vertically set on the top of clamp handle, and joint is arranged on clamp handle on the position of pincers beak, clamp handle passes through joint motion, and spring is arranged between clamp handle on the position away from pincers beak, the close joint；Described pincers beak is made up of left clamp beak and the right clamp beak of symmetric design, and left clamp beak upper end is triangular in shape, and lower part is rectangle, and a limit of this triangle is vertical, and the angle that b limit is formed with horizontal plane is 10 °, and angle formed by b limit and c limit is 45 °.
The a length of 10mm of pincers beak described above, thickness is 2mm, and the summit that a, b limit of its upper end triangle is formed is 2.5mm with the vertical dimension on c limit, a width of 1mm of rectangle of lower end.
Clamp handle described above is 5mm with the thickness of pincers beak junction.
Joint described above is for reversely clamping design.
Joint described above and pincers beak between distance be the distance between 30mm, and spring be 15mm, spring is compressive state, and when clamp handle is the most afterburning, left clamp beak and right clamp beak are closure state.
The method of corona dummy after the dismounting of a kind of backteeth crown removing pliers, the step of the method is as follows: first uses corundum car pin to close face at rear corona dummy tooth and grinds 2mm width, 5mm length, occlusal crib as deep as adhesive layer, the upper end of pincers beak is put in occlusal crib, clamping clamp handle makes the left clamp beak of pincers beak and right clamp beak separate, adhesive layer is wedged in the upper end of left clamp beak and right clamp beak, reinforcing makes rear corona dummy dislocate, and can be removed by rear corona dummy.
Beneficial effect:A kind of backteeth crown removing pliers that the present invention provides and the method for corona dummy after utilizing it to remove, have the advantages that
1. the pincers beak upper end of the backteeth crown removing pliers of the present invention be designed to ensure that pincers beak upper end facing of preferably fitting when embedding adhesive layer with the gap coming of age between dummy, and provides enough wedging forces, be the most also easier to wedge adhesive layer；
2. the backteeth crown removing pliers of the present invention is shockproof in demolishing process, can effectively reduce the sense of discomfort of patient；
3. the backteeth crown removing pliers of the present invention is to abutment without twisting resistance, nothing dislocation power, effectively alleviates the damage to abutment；
4. after the backteeth crown removing pliers of the use present invention is removed, operational approach during corona dummy is simple, and amount of grinding is few, can be greatly shortened the dismounting time.

Detailed description of the invention
Embodiment 1
The present embodiment provides a kind of backteeth crown removing pliers, this backteeth crown removing pliers by clamping beak 1, joint 2, clamp handle 3, spring 4 form, described pincers beak 1 is vertically set on the top of clamp handle 3, clamp handle 3 is 5mm with the thickness of pincers beak 1 junction, joint 2 is arranged on clamp handle 3 on the position of pincers beak 1, clamp handle 3 is movable by joint 2, and spring 4 is arranged between clamp handle 3 on the position away from pincers beak 1, the close joint 2；Described joint 2 is for reversely clamping design, and the distance between joint 2 and pincers beak 1 is 30mm, and the distance between spring 4 is 15mm, and spring is compressive state；Described pincers beak 1 is made up of left clamp beak 5 and the right clamp beak 6 of symmetric design, left clamp beak 5 upper end is triangular in shape, lower part is rectangle, the a limit of this triangle is vertical, and the angle that b limit is formed with horizontal plane is 10 °, and angle formed by b limit and c limit is 45 °, the a length of 10mm of pincers beak 1, thickness is 2mm, and the summit that a, b limit of its upper end triangle is formed is 2.5mm with the vertical dimension on c limit, a width of 1mm of rectangle of lower end.
