The invention relates to medicine, namely to prosthetic dentistry, and can be used in the manufacture of dentures removable and non-removable design.

The purpose of the invention is to reduce the time taken to take an impression by simultaneously obtaining two-jaw impressions in a central-occlusive position and saving impression material.

The drawing schematically shows the proposed blind spoon.

The spoon consists of a working surface 1 with a through groove 2 and with a mandibular vestibular border 3 and a handle 4. In addition, the spoon contains the palatal vault 5 with a sublingual side 6 located along the configuration of the alveolar process, as well as the vestibular maxillary dorsal side 7 , made on the mandibular bead 3 on the perimeter of the working surface 1. The working surface 1 also has jumpers 8. The surface of the spoon is perforated.

Steppe spoon is used as follows.

To obtain simultaneous impressions of both jaws in the central-occlusive position, it is necessary to prepare a lateral mass, place it on the working surface of 1 spoon, introduce it into the oral cavity and press it to the upper jaw. After that, the patient is asked to tilt the head back and close the jaws until the antagonist teeth are in full contact and the edges of the upper and lower jaws are processed in the appropriate way in the traditional way. In order to eliminate the deformation of the relief of the occlusal surface of the teeth, after applying a small amount of the dental impression mass, a strip of gauze cut into the shape of the through groove is placed on its surface and covered with another portion of the dental impression mass. Thus, the strip of gauze is

in the middle of the impression material. After taking the impressions in the central-occlusive position, the spoon is removed from the oral cavity and the models are cast in a known manner, plaster them into the occluder. In order to facilitate the separation of the impression spoon from the model of the lower jaw, a preformed mold of thermoplastic material is introduced into the space formed by the palatine vault and the catchboard 6.

The proposed construction of a double-jaw dental impression spoon makes it possible to simultaneously obtain impressions from both jaws in the position of the central occlusion, shortens the steps of making prostheses of both removable and non-removable structures. Much less than an impression material is used to produce casts, approximately the amount that is spent on one mold when the impression is taken with a standard dental impression spoon. In addition, the patient’s stay with the doctor is reduced, the productivity of the doctor and the dental technician increases.
