Короткий огляд (реферат): | The aim: Determination of the peculiarities of full-face aesthetics in patients aged 10-13 years with a distal bite with different types of mandibular growth. Materials and methods: 74 patients aged 10-13 years with a distal bite and various types of mandibular growth took part in the study. The methods of photostatic image study described by I.I. Uzhumetskene (1970), V.P. Pereverzev (1979) were used in this research. Results: To determine the type of face, a gl-me: zy-zy index was calculated. Index values ranging from 0.84 to 0.879 are indicative of a mesoprosopic (medium) type of face, an index less than 0.839 defines a europrosopic (broad) type, an index exceeding 0.88 is characteristic of a leptoprosopic (narrow) type. The facial shape in all patients was determined by the Izar facial-morphological index. Similarly, the facial shape can be determined by the facial tapered angle ( < FTA). In all groups of teenagers, a decrease in the angle is noted, which is indicative of an elongated, narrow face. To assess the ratio of the middle and lower parts of the face, the gl-sn:sn-me index was used, which is normally equal to 1. In our case, this index was higher than normal in all groups of children as compared to the control group (1.01±0.03). The p-p:zy-zy and p-p:go-go indices are indicative of the harmonious facial development transversally. Conclusions: Vertical and neutral-vertical type of mandibular growth results in a narrow (leptoprosopic) type of face; medium (mesoprosopic) and wide (europrosopic) types of face result from neutral, horizontal and neutral-horizontal types of growth. Irrespective of the type of mandibular growth, all patients with a distal bite have a short lower third of the face. The strongest aesthetic changes are reported in the group of patients with a predominance of the horizontal type of mandibular growth. |
