The invention relates to medical technology, in particular to dental instruments, and can be applied during examinations, medical, surgical and orthopedic treatment of teeth and the oral cavity.

The purpose of the invention is to provide a rigid fixation of the jaws of the patient during the inspection of the oral cavity by | Q installing clamps on the teeth.

Figure 1 shows the dental mirror, a General view; figure 2 is a section aa in figure 1; on fig.Z - section bb in figure 1; figure 4 - section bb In Fig, 2.

The dental mirror contains holders in the form of plates 2 and 3 pivotally connected by axis 1, each of which is provided with locks 4 and 5 for the teeth, respectively, the lower and upper jaws. Each of the plates 2 and 3, installed with the possibility of mutual radial movement, is provided with a mounting position in the form of a sleeve 6 with a sealing ring 7 for mounting the lever 8 with a spherical hinge 9 at its end.

The hinge 9 has an axis 10 of the mirror .11, the latter is installed with the possibility of turning about the axis Y, and the axis 10 is capable of turning relative to the hinge 9, the adjacent sides of the plates 2 and 3 are provided with a helical gear, the long side 12 of each section of the teeth 13 which is placed on each of the plates 2 and 3 from the location of the fixers for the teeth. In the far from the T-axis end of the plates 2 and 3, the latter are provided with grooves 14 and 15 coaxially with each other, in which a tensioning mechanism is installed in the form

The sliding mechanism pushes the plates 2 and 3 until the latch 5 of the upper plate 3 sits on the teeth of the upper jaw, j Next, it is desirable to move the plates 2 and 3 apart as far as possible to a certain angle to ensure that the clamps 4 and 5 are in close contact with the teeth, then rotate heads 17 on ". 90 Place plates 2 and 3 between each other. In this position, the patient cannot spontaneously close his mouth, which greatly facilitates the work of the doctor.

Then, turning the lever 8 in the sleeve 6 of the mounting position, turning the axis 10 relative to the spherical hinge 9 and turning the mirror 11 relative to the axis 10 sets the required position of the mirror 11 from the conditions of optimal visibility and begins the healing process. If it is necessary to remove the dental mirror, the head 17 is rotated by 90 to match the thickness o with the width of the grooves 14 and 15, a spatula is inserted into the gap between the plates 2 and 3, the plates are moved apart and the angle between them is pressed down on the upper one, after which the mirror is removed from the mouth. Installing a dental mirror on the left or right side differs only in the installation position of the lever 8 and is possible on the right side with the lower position of the lever 8 or on the left side with the upper position of the lever 8.
