RU2283620C1 - Method for determining kamper horizontal line projection on patient face - Google Patents

Abstract

FIELD: medicine.

SUBSTANCE: method involves marking points on patient face for building nose-ear line. Radiopaque bead-balls are fixed along vertical line near the nose wing and ear tragus. The bead ball positions are marked with paint on face skin. Lateral teleradiographic head examination is carried out. Kamper horizontal line position is traced on the image over anterior nasal spine and external acoustic duct base. The result is projected upon the face skin relative to pearl balls crossed by the Kamper horizontal line corresponding to the paint marks on the face skin.

EFFECT: high accuracy in building individual prosthetic plane; high prosthesis production quality.

Description

The invention relates to medicine, namely to orthopedic dentistry, and can be used in the manufacture of full and partial removable laminar dentures.

As a prototype of the method for determining the projection of the Campanerian horizontal on the patient’s face, the method of forming a prosthetic (occlusal) plane along the nasal line (tragonasal line), passing from the middle of the tragus of the ear to the base of the nose wing (Orthopedic dentistry / E.I. Gavrilov, A.S. Scherbakov . - M .. 1984. - S.365-366; Orthopedic dentistry / S.I. Krishtab. - Kiev, 1986. - S.247). That is, on the face, the Camperian horizontal corresponds to the nasal line (E.I. Gavrilov, A.S. Shcherbakov. Orthopedic dentistry. - M., 1984. - P.365). In addition, other landmarks of the location of the nasal line are described in the literature (Orthopedic dentistry V.Yu. Kurlyandsky. - M., 1969. - P.367; Restoration of complete loss of teeth / E.Ya. Vares. - Donetsk, 1993. - C .79 and others).

The disadvantages of the method for determining the Campuser horizontal along the nasal line:

1. The lack of consensus on the location of the nasal line on the face of a person, which leads to poor-quality prosthetics.

2. The points (landmarks) of the location of the nasal line on the face are determined by each doctor subjectively.

3. The location of the nasal line on the face depends on the structural features of the tissues of the face (nose wings, tragus of the ear, ear canal, etc.), which leads to serious inaccuracies in the prosthetics of patients with removable dentures.

The technical result, the achievement of which the creation of this invention is aimed, is to increase the accuracy of determining the prosthetic (occlusal) plane relative to the Camperian horizontal (according to its projection on the face) and, as a result, the full prosthetics of patients with removable plate prostheses.

The technical result achieved is achieved by the fact that in the method for determining the projection of the Campanian horizontal on the patient’s face, including drawing points on the face to form a nasal line, on the patient’s face in the region of the tragus of the ear and nose wing are attached radiopaque beads-balls in the vertical direction, marked with paint on the skin of the face of the location of the beads, beads, conduct a lateral tele-radiography of the head and in the resulting image through the anterior nasal spine and the base of the external auditory canal determine the position of the Campanerian horizontal, which is then projected onto the skin of the face relative to the bead-balls through which the Campanerian horizontal passed, according to their marks with paint on the skin of the face.

The method for determining the projection of the Campanerian horizontal on the patient's face is as follows.

On the patient’s face (Figure 1) in the region of the tragus of the ear 1 and the wing of the nose 2 in the vertical direction and parallel to each other, fix radiopaque beads-balls 3 with a diameter of 1-2 mm on a thread of 20-25 mm, for example a plaster. Mark with paint on the skin of the face, for example with a ballpoint pen or felt-tip pen, the location 4 of the bead-balls and conduct side teleretgenography of the head. On the roentgenogram (Figure 2), through the front nasal spine 5 and the base of the external auditory meatus 6, a Camperian horizontal 7 is drawn, which intersects the images of the radiopaque beads-balls 3. The bead-balls 3 through which the Campanerian horizontal 7 passed are determined, since (Figure 1) ) the projection of the Camperian horizontal is easily transferred to the patient's face.

The method for determining the projection of the Campanerian horizontal on the patient’s face allows us to build an individual prosthetic plane necessary for the precise placement of artificial teeth and, therefore, significantly improve the quality of prosthetics with full and partial removable laminar dentures.

The method for determining the projection of the Campanerian horizontal on the patient’s face was tested on 18 patients with complete absence of teeth. The results of prosthetics are good.

Claims (1)

A method for determining the projection of the Campanerian horizontal on the patient’s face, including drawing points on the face for the formation of the nasal line, characterized in that the patient’s face in the area of the ear tragus and nasal wing attach radiopaque beads-balls in the vertical direction, mark the location of the beads with paint on the face skin balls, conduct a lateral tele-radiography of the head and in the resulting image through the front nasal spine and the base of the external auditory canal determine the location of the Campus horizontal Which is then projected onto the skin of the face with respect to the beads, beads, through which passed kamperovskaya horizontal, according to their marks painted on the face skin.
