Изобретение относитс к медицине, 4 именно к стоматологии, в частности К ортодонтии, и может быть использо- дл измерени длины апикального с Е азиса челюстей при аномали х их раз1 ИТИЯ .The invention relates to medicine, 4 specifically to dentistry, in particular To orthodontics, and can be used to measure the length of the apical with E azis of the jaws with anomalies of their development.
; Цель изобретени - повышение точности измерени при аномальном раз- итии челюсти.; The purpose of the invention is to improve the measurement accuracy with abnormal jaw dilution.
; На чертеже изображено предлагаемое стройство, общий вид.; The drawing shows the proposed structure, general view.
Устройство вьшолнено из штанги со шкалой 1, кареткой 2 с нониусом, перпендикул рно штанге установлены из- tS мерительные ножки 3 и 4 с элементами креплени , выполненными в виде стопорного винта 5, причем одна ножка 4 вы- г|олнена в виде стержн , один конец KJoToporo жестко соединен с перпенди- 20 к|ул рно расположенной пластиной 6, а другим концом соединена с кареткой 2, причем стержень установлен с воз- ложностью вращени вокруг своей оси, 4 ножка 3 выполнена в виде иглы со 25 OTonoprfbiM винтом 5. The device is made of a bar with a scale of 1, a carriage 2 with a vernier, perpendicular to the bar, and equipped with measuring elements 3 and 4 with fastening elements made in the form of a locking screw 5, with one leg 4 extruded in the form of a rod, one The end of the KJoToporo is rigidly connected to the perpendicular-to-20 plate located 6, and the other end is connected to the carriage 2, the rod being installed with the possibility of rotation around its axis, 4 the leg 3 is made in the form of a needle with a 25 OTonoprfbiM screw 5.
Устройство работает следующим образом .The device works as follows.
Острие ножки 3, выполненное в ви- де иглы устанавливают на вершину меж-зо зубного сосочка в области центрапь- Цых резцов на модели верхней челюс- или на переднюю поверхность режу- 11|(их краев центральных резцов нижней челюсти по средней линии и фиксируют ,г бе стопорным винтом 5, при этом вы- doTy выступающей части иглы регулируют в зависимости от высоты коронок р)езца. Затем каретку 2 с нониусом перемещают по шкале 1 на такое рас- дд с то ние, чтобы пластина 6 второй нож- Ки 4 устанавливалась на контактные пункты между первыми и вторыми пос- тойнными мол рами, а ось ножки 4 сав- Пала со срединно-сагиттальной плос- дЗ костью модели челюсти. При несимметричном расположении мол ров,обусловленном односторонним укорочением зубного р да, ттравильной установки пластины добиваютс путем поворота измерительной ножки 4 вокруг оси с последующей фиксацией ее стопорным винтом 5. С помощью измерительных элементов (шкапы 1 и каретки 2) определ ют рассто ние между измерительными ножками которое соответствует длине апикального базиса, измер емой по методу Хауса.The tip of the stem 3, made in the form of needles, is placed on the top of the inter-dental papilla in the region of the central incisors on the upper jaw model or on the front surface of the incisor 11 (their edges of the central incisors of the lower jaw are centered and fixed g a locking screw 5; in this case, the protruding of the protruding part of the needle is adjusted depending on the height of the crowns of the p. Then the carriage 2 with a vernier is moved on a scale of 1 to such an extent that the plate 6 of the second knife-Ki 4 is installed on the contact points between the first and second permanent molars, and the axis of the leg 4 is pa- pal from the middle sagittal flat bone model of the jaw. With an asymmetrical arrangement of the molars, due to the one-sided shortening of the dental row, the etching installation of the plate is achieved by turning the measuring leg 4 around the axis and then fixing it with a locking screw 5. The measuring elements (scales 1 and carriage 2) are determined with the help of measuring elements which corresponds to the length of the apical basis, measured by the House method.
Использование предлагаемого устройства позвол ет производить измерени длины апикального базиса на модели челюсти с наибольшей точностью и наименьшими затратами времени. Применение устройства обеспечивает необходимую точность измерени длины апикального базиса независимо от высоты коронок зубов и степени развити альвеол рного отростка челюсти, а также при наличии деформации зубных р дов-сопровождающихс смещением первых посто нных мол ров. Благодар указанным преимуществам повьштаетс качество диагностики, исключаютс возможные диагностические ошибки и неточности, которые могут привести к выбору неправильного метода орто- донтического лечени .The use of the proposed device makes it possible to measure the length of the apical basis on the jaw model with the greatest accuracy and the least amount of time. The use of the device provides the necessary accuracy in measuring the length of the apical basis, regardless of the height of the crowns of the teeth and the degree of development of the alveolar process of the jaw, as well as in the presence of deformation of dental rows accompanied by displacement of the first permanent molars. Due to these advantages, the quality of diagnostics is improved, possible diagnostic errors and inaccuracies that may lead to the choice of the wrong orthodontic treatment are eliminated.
