FEATURES IN FORMATION BITE BLOCK FULL SECONDARY EDENTULOUS MAXILLA

Abstract

Research problems. To investigate a photostatic method adequacy of parameters of two planes: one passing through pupillary, and another – through the noso-ear line. Materials and research techniques. Before photography the head of the investigated fixed with the help photostatic designs of authors of this article. Photostatic pictures received from identical distance from investigated by means of the Nikon RS 7000 camera, SLik PRO 330 DX strengthened on a professional support. Investigated 46 photostatic pictures received at 23 patients with intact dentitions full face and a profile. The age of the investigated made from 42 to 50 years (men – 11, women-12). Results of research. In all 46 photostatic pictures received at 23 patients noted convergence of projective lines in a point of the cosmetic center. When crossing projective lines by pupillary and noso-ear lines of canines, in a point of the cosmetic center counter rectangular triangles are formed: ΔА`О`С on the right and ΔВ`О`D at the left. In the speci-fied triangles acute angles ے α on the right and ے α1 at the left are of interest. The size of the specified corners charac-terizes shift relatively each other the planes passing through pupillary and noso-ear lines and according to our data the following: on the right - from 4° to 7° - on the average M ± m = 5,26° ± 0,023 and at the left – from 5° to 9° on the av-erage M ± m = 5,91° ± 0,037. Conclusions. Results of our researches grant the right to draw the following conclusions: a) at creation of the occlusal plane of the bite roller in the frontal site on N.I.Larin's method the inaccuracies, bound are assumed that it is rejected up from the plane created at the level of the pupillary line on the average on 5,2° on the right and 5,9° at the left; b) at the level of canines, at their statement depending on a standard size of teeth of "Estedent", a deviation make 1,9 mm - 2,5 mm. These researches cause need of improvement of a way of formation of the occlusal plane according to N.I.Larin for increase of its accuracy that grows out of our further researches and messages.
