CON TEC LC LIGHT-CURING ADHESIVE IN ORTHODONTICS

This pa-per analyzes Con Tec LC light-cu-ring ad-he-si-ve which was used for bon-ding brac-kets to the te-eth. Bon-ding of ad-he-si-ve starts with the use of elec-tro-mag-ne-tic ra-di-a-tion, that is to say, ul-tra-vi-o-let light. The be-gin-ning of ap-pli-ca-tion of the-se ad-he-si-ves was in the eig-hti-es of the last cen-tu-ri-es 40 ex-trac-ted te-eth of fron-tal re-gion we-re used for the analysis of to-oth-brac-ket bond strength (the de-bon-ding for-ce along the sur-fa-ce of the brac-ket-ena-mel in-ter-fa-ce). The de-bon-ding pro-cess of fi-xed ort-ho-don-tic brac-kets, aimed at de-ter-mi-ning the strength of the for-ce ne-ces-sary to se-pa-ra-te the brac-ket from to-oth sur-fa-ce, was me-a-su-red by way of sin-gle-axi-al Stretch System in the Cen-tre for Bi-o-en-gi-ne-e-ring in Kra-gu-je-vac. The ten-si-le for-ce was ac-com-plis-hed at the con-stant speed of 1 mm/min, whi-le the de-vi-ce auto-ma-ti-cally re-cor-ded the for-ce with 0.3 N ac-cu-racy. Af-ter con-duc-ted re-se-arch, the ob-ta-i-ned re-sults we-re sta-ti-sti-cally pro-ces-sed and analyzed.At the end of conducted analysis, clinical-technical implications of examined Con Tec LC adhesive are presented.
