Detailed Description

The technical solution of the present invention is described in detail below with reference to the accompanying drawings. The embodiments of the present invention are only used for illustrating the technical solutions of the present invention and not for limiting, although the present invention is described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced with other equivalent solutions without departing from the spirit and scope of the present invention, which should be covered by the scope of the claims of the present invention.

Fig. 1 is a schematic structural view of an embodiment of the dental filling instrument of the present invention. As shown in FIG. 1, the dental filling instrument of this embodiment includes a first working end 100, a second working end 200, a bolt 300, first and second connecting bodies 400, and a handle 500. The handle 500 is an elongated body member, and the first working end 100 is disposed at one end of the handle 500, and the first working end 100 is connected to the handle 300 by a first connecting body. The second working end 200 is disposed at the other end of the handle 500, and the second working end 200 is connected to the handle 500 by a second connecting body. The first and second connectors 400 are fixedly connected to the handle 500. In this embodiment, the first connecting body is movably connected to the first working end 100 by a bolt structure, so as to facilitate replacement.

The functional surface 110 of the first working end 100 has a structure matching the dented and indented socket in the form of the occlusal surface (fig. 2) of the tooth, with a width of 5mm to 12mm from left to right and a length of 5mm to 12mm from top to bottom. The functional surface 210 of the second working end 200 has a width of 5mm to 12mm in the left-right direction and a length of 5mm to 12mm in the up-down direction, and has a structure matching with the buccal surface (fig. 3) or lingual surface (fig. 4) of the posterior teeth for forming the buccal side or lingual side of the posterior teeth.

In order to avoid the blockage of the adjacent tooth body when the first and second working ends function, in this embodiment, the connector 400 includes a folding angle θ of 75 ° to 160 °, an included angle α between the connector and the handle is 100 ° to 160 °, the working end further includes a screw, and an included angle γ between the functional surface and the screw is 90 ° to 180 °. In addition, the first working end 100 or the second working end 200 can be replaced by a conventional filling head 800, which has the following shape: round head shape, flat hammer shape, flat blade shape and the like, so as to be beneficial to saving resources and saving storage space.

By using the dental filling instrument of the embodiment, an operator can use the first working end and the second working end to respectively pressurize and carve the occlusal surface, the buccal surface and the lingual surface after picking up and delivering the filling material to the defect part to be filled with the removed saproplasm and roughly paving the composite resin or the glass ionomer cement and other materials by using a conventional filling instrument, so as to promote the recovery of the physiological prominence of the occlusal surface fossa, the buccal side and the lingual side, further use the conventional instrument to trim so that the filling form adapts to the occlusion of a patient and conforms to the original form of the patient, then carry out the steps of photocuring and the like, and finally carry out fine adjustment and trimming on the occlusion by matching with the occlusal paper. Therefore, the rapid form recovery of the affected teeth with the lost tooth forms on the occlusal surface, the buccal side and the lingual side of the posterior teeth can be assisted, and particularly, the large-area occlusal surface defect can be assisted.

When the temporary crown restoration is performed, the operator can also use the first functional surface and the second functional surface to respectively perform pressure shaping, food overflow and ditch formation on the self-setting material of the occlusal surface, the buccal surface or the lingual surface.

Practical application proves that the instrument of the embodiment is beneficial to assisting doctors to carve the tooth form, is convenient for dentists to fill the tooth, and relatively improves the quality and efficiency of tooth filling treatment. For young stomatologists with insufficient clinical experience, the dental filling instrument of the utility model can shorten the training time for filling the tooth body and improve the quality of filling the tooth body, so that the treatment effect can reach the expectation. In addition, the dental filling instrument of the embodiment can improve the operation and treatment efficiency of doctors, reduce the mouth opening time of patients, thereby saving the time cost of the patients and improving the comfort degree of oral treatment and the matching degree of the patients.

The above description is the common embodiments of the present invention, if the technician modifies the functional surface of the second working end or applies the functional surface to the filling and repairing of the deciduous molars and pre-deciduous molars, the content of the present invention should also be understood.
