Изобретение относитс  к области ортопедической стоматологии.This invention relates to the field of prosthetic dentistry.

Известен прибор дл  проверки прочности МОСТОВИДНЫХ зубных протезов, содержащий основание, нажимиой рычаг, фиксирующие винты и динамометр.A device is known for testing the strength of a MOST-DENTAL denture, which contains a base, a pressure lever, fixing screws and a dynamometer.

Однако таким устройством невозможно провер ть мостовидные зубные протезы в услови х , приближенных к физиологическим нагрузкам по условию прочности и допустимого прогиба мостовидного зубного протеза в зависимости от фактического усилии прикуса зубов.However, such a device cannot check bridges under conditions close to physiological loads, according to the strength condition and allowable deflection of the bridges depending on the actual bite of the teeth.

Цель предлагаемого изобретени  - обеспечение различных вариантов нагружени  протеза в процессе испытаний, а также измерение пере.мещений.The purpose of the present invention is to provide various options for loading the prosthesis during testing, as well as measuring displacements.

Дл  этого в предлагаемом приборе )ia основании установлена вертикальна  опора, шарнирно св занна  с нажимным рычагом, на конце которого установлен нажимной винт к динамо.метру; стойки креплени  протеза с подвижными ползунками, прижимной рычаг, шарнирно св занный с онорой, i направл ющий щтифт с иружиной.To do this, in the proposed instrument, ia, the base has a vertical support, pivotally connected to a pressure lever, at the end of which a pressure screw is mounted to the dynamo meter; prosthetic attachment racks with movable sliders, a clamping lever pivotally connected to the onor, i guiding pin with the spring.

Кроме того, на основании установлена стойка с индикатором.In addition, on the basis of the installed rack with the indicator.

На фиг. 1 изображен предлагаемый прибор, вид сбоку; на фиг. 2 - то же, вид сверху; на фиг. 3 - разрез по А-А на фиг. 1.FIG. 1 shows the proposed device, side view; in fig. 2 - the same, top view; in fig. 3 is a section along A-A in FIG. one.

Прибор содержит динамометр 1, установленный между верхним захватом 2 и нижним захватом 3, выполненным на основании 4, и.меющем вертикальную опору 5, на которой через шарнир 6 закреплен нажимной рычаг 7, спирающи11с  посредством нажимного винта 8 через верхний захват 2 на динамометр, а другим концом - на верхнюю часть тела протеза 9, установленного на подвижных ползунках 10, фиксируемых винтами 11 на стойке 12 относительно нажимного рычага.The device contains a dynamometer 1, mounted between the upper grip 2 and the lower grip 3, made on the base 4, and holding a vertical support 5, on which through the hinge 6 a pressure lever 7 is fixed, spiraling by means of the pressure screw 8 through the upper grip 2 on the dynamometer, and the other end is on the upper part of the body of the prosthesis 9 mounted on the movable sliders 10, fixed by screws 11 on the rack 12 relative to the pressure lever.

Дл  фиксации величины прогиба мостовидного зубного протеза 9 на стойке 13 установлен индикатор 14, св занный с прижимнымTo fix the amount of deflection of the bridge denture 9, an indicator 14 is mounted on the stand 13 and is connected to the presser

рычагом 15, который одним концом шарнирно закреплен на опоре 5, а другим поджат пружиной 16 через упорный винт 17 до упора с нижней частью тела мостовидного протеза .lever 15, which at one end is pivotally fixed on support 5, and the other is pressed by spring 16 through stop screw 17 against the stop with the lower part of the bridge's body.

Работает прибор следующим образом.The device works as follows.

В зависимости от необходимости иа подвижных ползунках 10 под упорной частью нажимного рычага 7 устанавливают различные конструкции МОСТОВИДНЫХ зубных протезовDepending on the need for movable sliders 10, various designs of BRIDGE dentures are installed under the stop part of the pressure lever 7.

дл  исиытани  их на прочность. При нажатии винто г 8 на динамометр 1 усилие его слсати  передаетс  через нажимной рычаг 7 на зубной протез 9, который, прогиба сь, взаимодействует с упорным винтом 17 и посредством прижимного рычага 15 фиксирует наto test their strength. When pressing the screws 8 on the dynamometer 1, the force of its slide is transmitted through the pressure lever 7 to the dental prosthesis 9, which, when deflected, interacts with the stop screw 17 and fixes it by means of the clamping lever 15.
