Description

TECHNICAL FIELD

[0001] The utility model relates to the field of false tooth processing, in particular to a multifunctional false tooth polishing head. BACKGROUND

[0002] After the false tooth is formed, it needs to be polished, and because the tooth shape of the false tooth is various, different polishing heads need to be rotated according to different false teeth in the polishing process, the existing polishing heads are mainly divided into conical, rhombic grinding head with prismatic grinding teeth on the surface processing, and cylindrical, annular grinding teeth on the ring surface processing, in the processing, the operator needs to polish the neck of the false tooth with the rhombic grinding head first, and then switch the cylindrical grinding head to grind the recess on the neck of the false tooth to increase the contact area of the false tooth and the base, in this process, the polishing time only needs a few seconds, but a lot of time is consumed to replace the polishing head, so it greatly affects the efficiency. SUMMARY

[0003] The utility model discloses a multifunctional false tooth polishing head, the polishing head integrates cylindrical grinding head and rhombic grinding head, and is improved, greatly facilitates the polishing processing of false tooth.

[0004] The utility model discloses a multifunctional false tooth polishing head, the polishing head integrates cylindrical grinding head and rhombic grinding head, and is improved, greatly facilitates the polishing processing of false tooth.

[0005] A multifunctional false tooth polishing head, comprising a needle handle and a polishing body integrally formed with the needle handle, the polishing body is conical, the larger diameter end of the polishing body is close to the needle handle, and the smaller diameter end of the polishing body is processed with a fillet, a plurality of parallel annular teeth are sequentially processed on the ring surface of the polishing body along the axial direction of the polishing body, and inclined teeth are processed between adjacent annular teeth, and the tooth top of the inclined tooth and the tooth top of the annular tooth are spaced apart by 0.5mm.

[0006] The width of the annular tooth is 0.6mm, and the spacing between adjacent annular teeth is 1mm.

[0007] The length of the polishing body is 13mm, and the large diameter end of the polishing body is 4.5mm.

[0008] The multifunctional false tooth polishing head provided by the utility model has the beneficial effects that a plurality of parallel annular teeth are processed on the polishing body, and inclined teeth are processed between the annular teeth, in the processing, the neck polishing and recess processing of the false tooth can be carried out by adjusting the angle of the polishing head, and the polishing efficiency is greatly improved. BRIEF DESCRIPTION OF DRAWINGS

[0009] To more clearly illustrate the technical solutions of the embodiments of this utility model, the drawings used in the embodiments will be briefly introduced below. It should be understood that the following drawings only show some embodiments of this utility model and should not be regarded as a limitation on the scope. For those skilled in the art, other related drawings can be obtained based on these drawings without creative effort.

[0012] Example

[0013] like Figure 1 As shown, the multifunctional denture grinding head provided in this embodiment includes a bur shank 1 and a grinding body 2 integrally formed with the bur shank 1. The grinding body 2 is conical, with the larger diameter end of the grinding body 2 close to the bur shank 1 and the smaller diameter end having a rounded corner. Multiple parallel annular teeth 3 are sequentially machined along the axial direction of the grinding body 2 on its annular surface. Helical teeth 4 are machined between adjacent annular teeth 3, with a distance of 0.5 mm between the tooth tip of the helical teeth 4 and the tooth tip of the annular teeth 3. The width of the annular teeth 3 is 0.6 mm, and the distance between adjacent annular teeth 3 is 1 mm. The length of the grinding body 2 is 13 mm, and the large diameter end of the grinding body 2 is 4.5 mm.

[0014] The method of using this utility model is as follows:

[0015] When grinding the neck of the denture, a certain angle can be deflected so that multiple ring teeth 3 can form a certain clamp to grind the neck at one time. When processing the groove, it is only necessary to rotate the processing angle to make the ring teeth 3 parallel to the groove to complete the processing of the groove. During the processing of the groove, the oblique teeth 4 between adjacent ring teeth 3 can also grind the grooves in sequence to reduce burrs.

[0016] The grinding head disclosed in this patent achieves the effect of multiple uses with a single needle. It can not only meet the basic grinding and adjustment of the length of the grinding cover ridge, but also make the finished tooth have striped grooves to better meet the later retention requirements of the denture base.

[0017] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any modifications and substitutions based on the technical solutions and inventive concepts provided by this utility model should be covered within the protection scope of this utility model. It should be noted that the structures or components illustrated in the accompanying drawings are not necessarily drawn to scale, and descriptions of well-known components, processing technologies, and processes are omitted to avoid unnecessarily limiting this utility model.
