Abstract
One of the most common stomatognathic system dysfunctions on the skeletal level is the maxilla’s narrowing. It is distinguished by front-teeth crowding, protrusion of the lower teeth past the front teeth, as well as a high-arched palate. The key method of orthodontic treatment of this pathology is applying dental braces with the palatal extension system working on the skeletal level. The most popular device is the Biederman appliance with the Hyrax screw, designed before the era of technological progress. As a result, the aim of the project was to present new constructional solutions for devices applied in cases of quick palatal suture expansion. Two biocompatible material solutions were prepared for the key part of the device – the screw. A comparative tension analysis with the use of two titanium alloys (Ti-13Nb-13Zr and Ti-6Al-4V) has been performed by means of the finite-element method.
