Description

Wax tooth engraving mold for human 3 times large right maxillary canine teeth

Technical Field

The utility model relates to a medical teaching auxiliary assembly technical field especially relates to a people's 3 big right upper maxillary canine tooth wax teeth sculpture moulds.

Background

At present, the volume of a wax block poured by a mold used by an oral cavity medical student in an oral cavity anatomical physiology experiment course is about 85mm multiplied by 35mm multiplied by 45 mm. The student needs to measure each part of data of the in vitro tooth of the person, then magnifies the measured data by 3 times, and draws the labial surface, the lingual surface, the mesial surface and the distal surface on the coordinate paper. And transferring the data on the coordinate paper to a wax block, and carrying out primary carving to form a 3-time large tooth wax block for removing the undercut and the appearance high point. However, these designs suffer from the following problems and disadvantages: students need to make coordinate drawings by themselves and develop the coordinate drawings on wax for carving, and in the process, the preliminary dicing manual operation has large error, inaccuracy, time and labor waste, wax waste and environmental pollution. On the premise of achieving the teaching target, a mould which can shorten the teaching time and improve the practice operation quality does not exist at present.

Disclosure of Invention

In order to solve the problem, the utility model provides a people's 3 big right upper maxillary canine tooth wax teeth sculpture mould, its aim at provides one kind and more accords with the teaching practice, makes things convenient for the student to use, shortens the teaching time, accurate reflection tooth anatomy characteristics, more green's mould. After melting the wax, filling the mould to finally obtain a wax block which is formed by manual carving and is 3 times as large as the undercut and the appearance high point of the right maxillary canine tooth of a person.

In order to achieve the above object, the utility model provides a pair of people's 3 big right upper maxillary canine tooth wax teeth sculpture mould is realized like this: the main material of this mould is the copper sheet metal, and nearly well buccal side and far away well buccal side junction are padlock formula structure, convenient connection, and nearly well lingual side and far away well buccal side are the shutter type switch, and the root bottom is open structure, makes things convenient for the pouring of wax.

In another aspect of the invention, the shutter switch is opened before the latch mechanism is unlocked, allowing the mold to be removed more easily.

Because the utility model discloses a structure of 3 times big right upper maxillary canine tooth appearance that are similar to people more to can obtain following beneficial effect: the cost of the wax block of 1/3 is saved, more green, the used wax bits of the student can be reused, the teaching time for reaching the teaching purpose is shortened, and the anatomical characteristics of the tooth are reflected more accurately.
