Abstract
One of the most common stomatognathic system dysfunctions on the skeletal level is the maxilla’s narrowing. Orthodontic treatment of defects occurs by using a Biderman appliance with a Hyrax screw. The appliance is placed in the jaw through the cemented rings on the premolars and molar teeth. The cement-mounting ring includes fluorine, still released to the tooth enamel, having a protective effect. Where the cement begins to crumble, it gradually weakens to maintain the ring and begins to move, or to slide up the tooth. Then, it is re-cemented, tightly filling the space between the ring and the tooth. As a result, the aim of the project was to present new conception rings whose use does not lead to a lack in enamel. The proposed new design was created in such a way that the halfring design makes it impossible to slip from a single tooth in the jaw. The project was designed to propose the shape and material of the biocompatible and durable material for the load. The comparative tension analysis and movements of the turnbuckle of the three used stainless steel (AISI 304, AISI 316L, AISI 430) have been performed by means of the finite element method (FEM).
