This pa­per analyzes Con Tec LC light-cu­ring ad­he­si­ve which was used for bon­ding brac­kets to the te­eth. Bon­ding of ad­he­si­ve starts with the use of elec­tro­mag­ne­tic ra­di­a­tion, that is to say, ul­tra­vi­o­let light. The be­gin­ning of ap­pli­ca­tion of the­se ad­he­si­ves was in the eig­hti­es of the last cen­tu­ri­es 40 ex­trac­ted te­eth of fron­tal re­gion we­re used for the analysis of to­oth-brac­ket bond strength (the de­bon­ding for­ce along the sur­fa­ce of the brac­ket-ena­mel in­ter­fa­ce). The de­bon­ding pro­cess of fi­xed ort­ho­don­tic brac­kets, aimed at de­ter­mi­ning the strength of the for­ce ne­ces­sary to se­pa­ra­te the brac­ket from to­oth sur­fa­ce, was me­a­su­red by way of sin­gle-axi­al Stretch System in the Cen­tre for Bi­o­en­gi­ne­e­ring in Kra­gu­je­vac. The ten­si­le for­ce was ac­com­plis­hed at the con­stant speed of 1 mm/min, whi­le the de­vi­ce auto­ma­ti­cally re­cor­ded the for­ce with 0.3 N ac­cu­racy. Af­ter con­duc­ted re­se­arch, the ob­ta­i­ned re­sults we­re sta­ti­sti­cally pro­ces­sed and analyzed.

At the end of conducted analysis, clinical-technical implications of examined Con Tec LC adhesive are presented.

Keywords: Con Tec LC, adhesive, orthodontics.
