Early revealing and complex treatment measures with consideration of pathology in children with congenital oligodentia allow qualitatively rehabilitate patients health and face esthetics.
Evaluation of soft tissue facial profile is a mandatory' part of cephalometric analysis. Due to the structural features of the facial skeleton in men and women should have a clear idea of the aesthetic problems in the correction of dentofacial anomalies [2]. For us, this was the reason to search with the greatest aesthetic value of the facial features of men and women [5,6].
The aim of the study was to examine gender differences profile of soft tissues with orthognathic occlusion.
Material and methods
To solve this problem have been studied 73 cephalograms of persons with orthognathic occlusion. Cephalogramms produced by the machine J.MORITA 3D MFG with cephalostat. Identification of anthropometric points and reference cephalometric planes produced by the method of SS Steiner (1960). V.A. Sassouni (1964). W.V. Downs (1948). R.A. Reidel (1957). Ch. Tweed (1946). R.M. Ricketts (1970). R.A. Holdaway (1983). In order to determine the features of the soft tissue profile of the procedures used Y.Ch. Park and Ch.J. Burstone (1986). Ch.G. Zylinski. R.S. Nanda. S. Kapila (1992). G.W. Arnett (2004). We consider a set of profile parameters of soft tissues of the face and facial bones of the skull, which includes 78 parameters, including 67 for profile. Standard statistical analysis was carried out in Word Excel, and includes the determination of the average values of the parameters; variance and standard deviation; confidence interval for the specified probability; correlation coefficient, showing, in particular, the connection parameters of the skeletal profile and the profile of the soft tissues.
Results and discussions
According to the results of statistical processing of the parameters of the soft tissue profile of the person, a table showing the differences by gender profile of the studied parameters of the soft tissues of the face is presented. Determmation of sex differences parameters such as the facial skeleton and soft tissue facial profile is essential when planning orthodontic treatment [3.4]. The results of evaluation of gender differences in the structure of soft tissue profile in patients with orthognathic occlusion shown in table.
The length of the upper hp in men and women were significantly different and thus should be considered as important diagnostic criteria, especially when planning an orthodontic treatment. So. in men it is approximately 2,5 mm longer than that of women, as noted in the works of other authors. Thus, W. Arnett (2004) shows the difference of 3,4 mm. The same applies to the thickness of the upper lip. In our study, a difference of about 3,1 mm. whereas in W. Arnett - 2,2 mm. The thickness of the base of the upper hp m men more than an average of 2,7 mm. which was confirmed by Y.A. Gioeva and L.V. Polma [1]. The length of the lower hp in women with less occlusion for ortho gnathic 4.6 nun while for W. Arnett - about 7.4 mm. Chin women less than men, 6,5 mm. The height of the lower face of men more than 9,2 mm Bridge of the nose is longer in men than in women. 4,2 mm.
