JPS6036263Y2 - Polished fixed forceps for dental technology - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to a fixed forceps used for polishing inlays, crowns, which are crown prostheses for teeth used in dental treatment, as well as dentures, bridges, bars, clasps, and the like.

Inlays, crowns, bridges, bars, clasps, etc. used in dentistry are made of metal and are used to replace missing teeth of patients.
It must be restored to its original state and have the same functionality.

Therefore, these shapes require extremely detailed machining.

Therefore, it must perfectly fit the patient's teeth, and the crown prosthesis and denture anchors are molded in the mold of the patient's teeth and polished with a grindstone to match the patient's affected area. Work is required.

These dental materials have complex shapes, some of which are extremely small, and are made of metal, so the degree of polishing is extremely delicate.

Therefore, it is not only difficult to perform delicate work by holding these items by hand, but also inconveniently causing latent scratches on the hand or causing the dental material to fall onto the floor.

Therefore, recently, polishing forceps have been used, but although they are both specified for use with inlays and crowns, they are not suitable for small inlays, and crowns are also used when the crown of the tooth is short. This method cannot be used, and there are many points in which it is unsuitable for fixing dental crown prostheses, so there is a risk that they cannot be sufficiently fixed and held, and may come off from the fixing forceps during polishing.

The present inventor has devised a polished fixing forceps for dental techniques that eliminates these drawbacks and can be easily and firmly fixed and held.

In the present invention, one of the clamping bodies 1 is curved outward in a substantially semicircular arc shape,
The ends of both clamping bodies 1 and 2 are bent inward horizontally to form a clamping part 3.
, 3', and the tips 4 and 5 of both clamping parts are provided with a cross groove on both sides, or a cross groove on one side and a straight groove on the other side.

In the forceps of the present invention, one of the clamping bodies 1 is curved outward in a semicircular arc shape, and the tips of both clamping bodies are bent horizontally inward.
When polishing a round as shown in the figure, the tip can be fully inserted into the crown, it can be firmly held with the tip of the other clamp body 2, and the tip should be shaped like a cross or a cross. This creates a single-shaped groove that can properly grip the edges and ridges on the front or back surface of the crown.

In addition, when the forceps of the present invention are used to hold clasps, inlays, and veneers, as shown in Figs. , it can properly hold the edges and ridges of each material, making it extremely convenient for processing these.
