Abstract

Inventia se refera la o instalatie pentru determinarea parametrilor functionali ai pieselor dentare, destinata determinarii parametrilor functionali ai pieselor dentare, folosite în stomatologie si utilate cu diverse tipuri de freze. Instalatia, conform inventiei, este alcatuita dintr-o placa de baza, pe care, cu ajutorul unor montanti, este fixata piesa dentara actionata de un brat Doriot si avînd montata, în cap, freza de încercat. Pe o coloana articulata pe placa de baza sînt prevazute doua brate suport reglabile în înaltime. Pe bratul superior este montat un comparator iar pe cel inferior un suport în care culiseaza o piesa de sustinere pe care este fixat materialul dentar. în acelasi suport este fixat un cutit pe care se sprijina o pîrghie actionata de o greutate cu fir a carei cursa este limitata de un opritor. Cu capatul celalalt pîrghia împinge prin intermediul unui microrulment piesa de sustinere, modificarea pozitiei pîrghiei fiind sesizata de comparator. Actionarea piesei dentare se face prin intermediul unui brat Doriot iar turatia frezei se determina cu ajutorul unui traductor inductiv si al unui numarator de impulsuri.The invention relates to a device for determining the functional parameters of the dental pieces, intended to determine the functional parameters of the dental pieces, used in dentistry and equipped with various types of mills. According to the invention, the installation consists of a base plate, which, with the aid of some supports, is fixed to the dental piece actuated by a Doriot arm and having the test cutter mounted in the head. On a column hinged on the base plate are provided two height adjustable support arms. A comparator is mounted on the upper arm, and on the lower one a support in which a support piece on which the dental material is attached. In the same support a knife is fastened on which a lever is actuated by a weight with a thread whose stroke is limited by a stop. With the other end, the lever pushes the support piece through a microrulate, the change of the position of the lever being sensed by the comparator. The action of the dental piece is made through a Doriot arm and the rotation of the cutter is determined by means of an inductive transducer and a pulse count.
