Короткий огляд (реферат): Автором статьи предложен метод определения межальвеолярной высоты при патологиче­ ской стираемости зубов. Предложенная методика позволяет наиболее точно измерять изменение величины высоты прикуса у лиц, которым жевательная поверхность зубов восстановлена керамическими вклад­ ками и фотополимерными материалами. С целью косметического протезирования при горизонтальной патологической стертости зу­ бов установлено, что нужно избегать восстановления группы моляров фотополимерными мате­ риалами, а применять керамические вкладки.; The author proposed a method of determining the occlusal vertical dimension at the pathological dental abrasion. Proposed method allows most accurately determining the vertical dimension of occlusion in persons having chewing surface of teeth restored with ceramic inlays and photopolymer materials. To determine tooth crowns abrasion value, we used radiopaque markers within dental pit (ekdostelit) of permanent maxillar and mandibular first molars made of Ceram X (Germany) photopolymer filling material. The distance between lower border of marker on the mandibular teeth and the upper border of marker on the maxillar teeth before fixing inlays, right after fixing them and in 3 months was measured on panoramic image. The difference between these indices was the abrasion value. Panoramic image was taken when teeth were closed in a central occlusion. The distance between dental pit (ekdostelit) and medial and distal buccal cusp tip was also measured right after fixing inlays and in 1 year to determine what antagonist will be erased more and its abrasion value. The study showed that in patients with ceramic inlays the figures of distance between dental pit (ekdostelit) and cusps of 16th tooth and 26th tooth were similar and amounted 6. 5 ± 0.22 mm and 6.5 ± 0.14 mm. On 36th tooth the distance was 4.07 ± 0.25 mm and on 46th tooth it was 4.0 ± 0.18 mm. Noteworthy that in 1 year of using ceramic inlays the distance between dental pit (ekdostelit) and cusps of 16th, 26th, 36th, and 46th teeth were the same as in the day of fixation. In patients with dentitions restored with photopolymer materials on the day of overlaying photopolymer materials, the distance between 16th and 26th teeth was 5.94 ± 0.23 mm and 5.88 ± 0.21 mm respectively and in 1 year the distance had changed to 5. 59 ± 0.17 mm and 5.65 ± 0.19 mm accordingly. The distance between dental pit (ekdostelit) and cusps of 36th and 46th molars also decreased. If on the day of restoration this distance was 4.06 ± 0.23 mm and 4.06 ± 0.16 mm, then in 1 year these figures decreased to 3.53 ± 0.12 mm and 3.65 ± 0.17mm respectively. We conducted odontometric measurements of the distance between dental pits of 16th /46th maxillary molars and 26th /36th mandibular molars. After fixing ceramic inlays, the distance between dental pits (ekdostelits) amounted 8.64 ± 0.49 mm and 8.71 ± 0.35 mm; and in 1 year of using prostheses, this distance was almost unchanged 8.64 mm ± 0.39 and 8.71 ± 0.27 mm. On the day of restoration therapy of 16th, 26th, 36th, and 46th teeth, the distance between dental pits (ekdostelits) of 16th /46th was 7.53 ± 0.36 mm and 7.59 ± 0.41 mm respectively. In 1 year of using dentition recovered with photopolymer materials, the distance between dental pits (ekdostelits) of 16th / 46th and 26th /36th teeth decreased and amounted to 6.94 ± 0.29 mm and 6.82 ± 0.28 mm respectively. For the purpose of a cosmetic prosthetics at a horizontal pathological tooth wear, we have found that the restoration of group of molars with photopolymer materials should be avoided; ceramic inlays should be used instead.
