A device for fixation of the head during photometry (figure 1), including the supporting rack 1 installed on it millimeter by line 2 and round base 3 for ear clamps 4 and 5 included in the external auditory meatus, and the plate 6 with a cutout for the nose, which is the benchmark for compliance with the Frankfurt horizontal (FH) and rests on the lower margin of the orbit (Orthodontics, trauma, jaw and facial prosthetics: satin. P.II. / Under the editorship of Prof. Voukourestiou. - M., 1970, p.69-70).

The disadvantage of this device is the presence of all the supports 3, which when conducting photography can be seen on the film and does not allow to measure hidden it necessary to explore points of the face. In addition, the possibility of fixation of the head in a horizontal direction does not provide identity even two consecutive frames. Millimeter ruler, located in the vertical plane, with dimensions on the digital image gives distortion.

The objective of the invention is to improve the reliability of fixation of the patient's head and the accuracy of the measurements.

This is due to the fact that the bearing consists of upper and lower parts, located parallel the but each other, having T-shaped and connected to rotate 90 degrees, while its lower part is fixed to the latch ear, the latch nose and the clamp head can move up and down and front to back; and on top, fixed on a support rack, installed millimeter ruler, United with the letter P.

Bearing consisting of two parts: upper and lower, parallel to each other and can be rotated through 90 degrees, allows the photographing of the patient profile and from the front without removing the support; and T-shaped parts support is most convenient for fixing the elements - they do not appear on the image. The presence of the tabs of the ear, nose and neck ensure a reliable fixation of the patient's head in the vertical and horizontal directions, and the ability to move them up and down and front to back allows to take into account the different dimensions of the head; and a millimeter ruler, made in the form of the letter U, to avoid the occurrence of errors in the measurements on digital images.

Device for fixing a head by photometry (figure 2), containing the supporting rack 1, the support 3, the latch ear 4, the latch nose 5 and the lock head 6, millimeter ruler 2, made in the form of the letter P. Bearing has an upper part 7 and the bottom 8, R is polozhenie parallel to each other; each of which has a T-shape. Parts 7 and 8 of the support 3 is connected can be rotated 90 degrees. On the lower part 8 of the support 3 is fixed to the latch ear 4, the latch nose 5 and the lock head 6, which can move back and forth and up and down. The upper part 7 of the support 3 with a millimeter ruler 2 is fixed on the supporting rack 1.

The device operates as follows: the upper part 7 of the support 3 with a millimeter ruler 2 is fixed on the supporting stand 1; a latch ear 4 is installed on the lower part 8 of the support 3 and is fixed in the outer ear canal of the patient, the latch nose 5 impose on nosolobnogo the seam and lock head 6 - under point opisthocranion in accordance with the size of the patient's head, after which produce a photograph in profile and full face.

SUBSTANCE: method involves taking imprints from upper and lower jaw for manufacturing plaster jaw models. The lower jaw plaster model is used for measuring mesiodistal dimensions of twelve teeth: 46-41 and 31-36. Particular tooth lacking, its dimensions are calculated using percent proportions from mean dental parameter values table. Individual general projection length norm is calculated for upper and lower jaw using formulas; Lpo=0.39*Σ12 and Lpu=0.35*Σ12, where Lpo and Lpu are the individual general projection length norms of lower and upper jaw, respectively; 0,39 and 0,35 are indices describing relationship binding mean general projection length of lower and upper jaw to mean sum of mesiodistal dimensions of twelve teeth(46-41 and 31-36) of lower dental row in persons having physiological occlusion and permanent teeth dimensions within the limits of mean values, respectively; Σ12 is the sum of mesiodistal dimensions of twelve teeth(46-41 and 31-36) measured on plaster model. Individual norm values of general upper and lower jaw projection length are compared to corresponding actual values measured on models. The values coinciding, conclusion is drawn concerning normal sagittal dimensions of denture. Difference being positive, increase in sagittal denture dimensions is considered to be the case. The difference being negative, reduction of sagittal denture dimensions is considered to be the case. Actual projection length values of the anterior segment are additionally determined by taking measurements from upper and lower jaw models, with distance between mesial point on labial approximal surface of incisor in vestibular position and point of intersection of line joining contact points of canine tooth and the first molar on the left and right side to median line of the upper jaw. Distance between contact point of lower central incisors cutting surfaces and point of intersection of line joining contact points of the first and the second premolars on the left and right side to median line of the lower jaw. Individual general projection length norms are calculated for upper and lower jaw anterior segment using formulas: lpo=0.16*Σ12 and lpu=0.17*Σ12, where lpo and lpu are the individual general projection length norms of lower and upper jaw anterior segment, respectively; 0,16 and 0,17 are indices describing relationship binding mean general projection length of lower and upper jaw anterior segment to mean sum of mesiodistal dimensions of twelve teeth(46-41 and 31-36) of lower dental row in persons having physiological occlusion and permanent teeth dimensions within the limits of mean values, respectively; Σ12 is the sum of mesiodistal dimensions of twelve teeth(46-41 and 31-36) measured on plaster model. Individual norm values of general upper and lower jaw anterior segment projection length are compared to corresponding actual values measured on models. The values coinciding, conclusion is drawn concerning normal sagittal dimensions of denture. Difference being positive, increase in sagittal dimensions of anterior denture segment is considered to be the case. The difference being negative, reduction of dimensions of anterior denture segment is considered to be the case.
