Abstract

Dental moldable spoon for taking imprints of the upper and or lower jaw comprises a main body with guide elements for use during insertion. The spoon is made of deformable, sterilizable plastic.

Description

Dental impression trays are state of the art Metal or plastic with which either upper and lower jaw separate be molded or simultaneously.

These spoons are intended as single-use spoons. This pollutes the environment. Moreover they are in no way sufficiently stable.

The sense of the invention is therefore one stable spoon frame - especially made of sterilizable plastic that has a stable spoon handle and vertical retentions on the inside facing the rows of teeth undercuts e.g. in the form of omega figures. On the palate is advantageously a connection between the two spoon legs intended. This will make the spoon further stabilized and there can also be an available one if required Palatal part to be plugged on.

The actual impression can be taken at correspondingly stable impression material even without inserting Gauze or fabric are made which results in an instant real one Bite of the patient is present without anything contacting the Row of teeth bothers. This is particularly interesting for new manufacturing techniques in the future of dentures, e.g. by laser scanning of the teeth and digital recording the shape of the ground stumps.

Alternatively, this can also be done Spoon fits designed inner part of the spoon with gauze insert.

The positive guides on the sides of the mission have to then exactly in the negative leads of the spoon fit. This has to prevent the insert from slipping sensibly sublime stops at the end of its insertion position outside over the spoon grab and possibly snap. It can also be found in the bottom part of the Retentions of the spoon Stops were installed, but that would be cleaning the spoon difficult.

For dental model making This can then be used after the model materials have hardened from the spoon can be removed and archived.

The undercuts of the spoon in its side walls to lead to a reliable Hold the impression material and therefore it makes sense to keep the To use the insert so that it still holds the impression material guaranteed is.
