Description

Bonding formula porcelain wainscot carries ware

Technical Field

The utility model relates to the technical field of medical appliances, concretely relates to bonding formula porcelain wainscot carrying device for the carrying of wainscot when porcelain wainscot bonds, convenient operation does not influence the clinical treatment of every position of porcelain wainscot, has reduced the technological sensitivity that the porcelain wainscot bonded.

Background

The porcelain veneer restoration is a restoration mode of adhering a porcelain veneer and an abutment together by utilizing an adhesive material, and is used for the situations of tooth color defect, insufficient tooth volume, abnormal tooth structure, slight tooth arrangement abnormality and the like. With the improvement of health consciousness and aesthetic requirements of people, the porcelain veneering repair is widely applied to the field of aesthetic repair as a minimally invasive and beautiful repair mode. Compared with a full crown, the ceramic veneering repair has less or even no grinding of the ground tooth body tissues; after the tooth body is prepared, the tooth body is mainly bonded on the enamel layer, so that the bonding strength is high; the aesthetic effect is stable as well, and the biocompatibility is good. The preparation amount of the porcelain facing is small, but the technical requirements of a repairing doctor on the porcelain facing are higher, and the requirements on each step in the repairing process are stricter. In the clinical operation process, the porcelain facing is not easy to carry in the processes of cleaning, acid etching, bonding and the like because the porcelain facing is light and handy; in the past, doctors clamp and fix the ceramic veneers by hands or tweezers, but the edges of the ceramic veneers are thin and easy to damage and fall off, and the holding positions of fingers are difficult to clean and process, so that the final bonding effect is influenced; when the tweezers are used for clamping the porcelain veneers, the porcelain veneers are easy to fall off or the porcelain edges are damaged due to overlarge clamping force, so that the porcelain veneers are carried to become key points and difficult points in the repairing process.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a cotton double faced adhesive tape bonding formula porcelain wainscot of PE bubble carries ware for carrying of porcelain wainscot among the porcelain wainscot repair process, the operation of being convenient for practices thrift clinical time, reduces the clinical technique degree of difficulty, for solving in the past the porcelain wainscot carry in-process easily drop easy damaged scheduling problem provide new method.

The utility model provides a scheme that above-mentioned technical problem adopted is:

a bonded ceramic veneering carrier comprises a PE foam core part and a fixing rod for fixing the PE foam core part, wherein the PE foam core part is of a columnar structure, a fixing hole for fixing the bottom end of the PE foam core part is formed in the end surface of the fixing rod, the diameter of the fixing hole is not smaller than that of the lower end surface of the PE foam core part, a core cap is connected to one end, provided with the fixing hole, of the fixing rod through threads, and a fixing through hole for fixing the upper end of the PE foam core part is formed in the core cap; the PE foam core is characterized in that an adhesive layer is arranged on the upper end face of the PE foam core, and a protective layer covers the upper surface of the adhesive layer.

Preferably, the PE foam core part is of a conical columnar structure with a small top and a large bottom, and the fixing through hole is of a conical columnar structure.

Preferably, a shell is sleeved outside the fixing rod, the core cap is in threaded connection with one end of the shell, a plastic protective cap is in threaded connection with one end of the shell, which is far away from the core cap, and the front end and the rear end of the fixing rod are fixed by the plastic protective cap and the core cap.

Preferably, the fixing through hole is sized such that the PE foam core protrudes at least 5mm above the core cap.

The utility model has the advantages of it is following and effect:

firstly, the carrying mode is reliable, the bonding layer and the surface of the dried porcelain veneer can form good bonding, the PE foam is light and soft, the porcelain veneer has small stress in the bonding process, the surface porcelain layer is not damaged, the bonding surface of the porcelain veneer can be completely exposed, and the cleaning, acid etching and bonding treatment processes of the porcelain veneer cannot be influenced;

secondly, the adhesive type carrier is convenient to hold, the adhesive type carrier is of a rod-shaped structure, the holding is convenient, the contact area of fingers and the carrier is enough, and the friction force is large and the carrier is not easy to slip;

thirdly, the installation is convenient and fast, the disassembly is simple, the PE foam core part is only required to be arranged in the fixing hole in the rod part and the core cap is sleeved during the installation, and the disassembly process is opposite to that of the PE foam core part;

Fig. 1 is a schematic structural view of the bonded porcelain veneer carrier of the present invention.

The figures in the drawings are labeled as:

1, a plastic protective cap; 2, fixing a rod; 3, PE foam core part; 4, a core cap; 5, a housing; and 6, an adhesive layer.

Detailed Description

For better understanding of the present invention, the following examples are further illustrative of the present invention, but the present invention is not limited to the following examples.

Example 1

A bonded ceramic veneering carrier comprises a PE foam core part 3 and a fixing rod 2 used for fixing the PE foam core part 3, wherein the PE foam core part 3 is of a columnar structure, a fixing hole used for fixing the bottom end of the PE foam core part 3 is formed in the end face of the fixing rod 2, the diameter of the fixing hole is not smaller than that of the lower end face of the PE foam core part 3, a core cap 4 is connected to one end, provided with the fixing hole, of the fixing rod 2 through threads, and a fixing through hole used for fixing the upper end of the PE foam core part 3 is formed in the core cap 4; the PE foam core part 3 is characterized in that an adhesive layer 6 is arranged on the upper end face of the PE foam core part, and a protective layer covers the upper surface of the adhesive layer 6.

The PE foam core part 3 is of a conical columnar structure with a small upper part and a large lower part, and the fixing through holes are of a conical columnar structure.

The outer sleeve of the fixed rod 2 is provided with a shell 5, the core cap 4 is in threaded connection with one end of the shell 5, far away from the core cap 4, is in threaded connection with a plastic protective cap 1, and the front end and the rear end of the fixed rod 2 are fixed by the plastic protective cap 1 and the core cap 4, so that the fixed rod 2 is prevented from slipping.
