Abstract

The utility model belongs to the technical field of oral cavity devices, in particular to temporary braces, which comprises a sleeve body, a handle and a connector and is characterized in that the sleeve body is center hollow structure, the same shape with a normal dental corona, dividing into anterior teeth unit and buccal teeth unit. An overflow port is arranged in the middle at a tongue side of the sleeve body, a circular opening is disposed at a bottom of the sleeve body, the handle is an elliptic annular structure and the handle is connected with the two sides at the bottom of the sleeve body by a connector. The utility model is disposable and can be operated simply and easily and boiled under high temperature and sterilized directly by ultraviolet ray; the utility is safe and practical and is convenient for popularization and the cost is low.

Description

Interim tooth becomes jacket

Technical field

This utility model belongs to the oral device technical field, is specifically related to a kind of interim tooth and becomes jacket.

Background technology

The oral cavity doctor after the tooth preparation, need make interim leaf-comb or interim fixed bridge for patient in the process of fixed and repaired.The several different methods operation of adopting at present is all complicated, and more common in the world method is to use the acrylic resin teeth of preformation.By outside mouth, comparing, select comparatively approaching model, after through in mouth, comparing repeatedly, finally grind out suitable interim leaf-comb.This method can have been spent a large amount of time when grinding, and is difficult for making fixed bridge.

Summary of the invention

The purpose of this utility model is to provide a kind of interim tooth to become jacket.

The interim tooth that the utility model proposes becomes jacket, is made up of body 1, handle 2 and connector 3, and its structure as shown in Figure 1.Wherein, body 1 is the middle part hollow-core construction, and its shape is divided into proteroglypha and backteeth group, as shown in Figure 3 with the profile of normal corona; Body 1 tongue middle side part is provided with overfolw hole 5, and the bottom of body 1 is provided with circular open 4, as shown in Figure 2, handle 2 ovalize circuluses, body 1 two bottom sides connects handle 2 respectively by connector 3.

In this utility model, the diameter of circular open 4 is 3mm-7mm, and its all footpath is less than the Zhou Jing of body 1 cervical region.

Easy and simple to handle being easy to of this utility model grasped, and be with low cost, disposable use, and safe and practical being convenient to promoted.SEBS belongs to thermoplastic elastomer (TPE), is the character that has vulcanite under a kind of room temperature, the macromolecular material that at high temperature can be plastically deformed again.Can adopt processing of plastic method (injection moulding, extrude, blowing and casting etc.) to produce.The SEBS elastomeric material is nontoxic, can not produce irritated, variation and rejection, have that air-tightness is good, a heatproof, ageing-resistant performance, both have plasticity tissue, have elastomeric property again and use high temperature steaming and ultraviolet directly to sterilize, therefore can be used as the basic material of medical apparatus and instruments

Number in the figure: 1 is body, and 2 is handle, and 3 is connector, and 4 is circular open, and 5 is overfolw hole.

The specific embodiment

Further specify this utility model in conjunction with the accompanying drawings below by embodiment.

Interim tooth becomes jacket, all is that thermoplastic elastomer (TPE) SEBS makes, and is made up of body 1, handle 2 and connector 3, and its structure as shown in Figure 1.Wherein, body 1 roughly is divided into proteroglypha and backteeth group, as Fig. 4 for its thickness is about the profile and a series of shapes of size formation of 0.5mm thin film according to normal corona.Body 1 tongue middle side part has a circular hole, is overfolw hole 5, and diameter is 2mm.Body bottom 4 is a circular open, and as Fig. 3, its diameter is not waited by 3mm to 7mm, and its week directly all is slightly less than the Zhou Jing of corresponding tooth body cervical region.Lever 2 is an elliptical ring, thick about 2mm, and its internal diameter is about 10mm most, the shortest about 5mm.Cover body 1 is linked to each other by connector 3 with handle 2, and connector 3 is the round bar of thick 1mm, and handle 2 is connected in body bottom 4.

When using this utility model, the oral cavity doctor selects to become jacket with the matched interim tooth of tooth body size after finishing the tooth preparation of leaf-comb.An amount of haircuts phase self curing plastic is inserted in the body 1.The circle that slightly struts body bottom by handle 2 opens 4, the tooth body after making it tightly be paperwrapped in preparation, and gum is in place to exerting pressure.The self curing plastic of unnecessary haircuts phase is overflowed by the overfall 5 of body 1 tongue side and is removed.Treat that plastics enter dough period, nibble, adjust interlock by patient.After plastics solidify, cut off being connected of connector 3 and body 1, handle 2 is separated with body 1 with connector 3 with instruments such as eye scissorss.So far finish the making of interim tooth.If make temporary fixed bridge, then the proximal surface at body 1 spiles, and makes adjacent interim tooth have self curing plastic to be connected, and all the other steps are with opening existing leaf-comb operational approach.

Claims

1. an interim tooth becomes jacket, form by body (1), handle (2) and connector (3), it is characterized in that body (1) is the middle part hollow-core construction, its shape is with the profile of normal corona, be divided into proteroglypha and backteeth group, body (1) tongue middle side part is provided with overfolw hole (5), and the bottom of body (1) is provided with circular open (4), handle (2) ovalize circulus, body (1) two bottom sides connects handle (2) respectively by connector (3).

2. interim tooth according to claim 1 becomes jacket, and the diameter that it is characterized in that circular open (4) is 3mm--7mm, and its all footpath is less than the Zhou Jing of body (1) cervical region.
