Abstract

U modernoj dentalnoj implantološkoj protetici postoji trend korištenja unutarnjih koničnih konekcija. S obzirom da različiti proizvođači nude različite kutove konusa, najčešće od 1,5° do 45°, postavlja se pitanje biomehaničke uspješnosti pojedinih konekcija pa tako i implantoloških sustava. Veza između nadogradnje i implantata ostvaruje se putem predopterećenja vijka, a otpuštanje tog vijka uslijed cikličkog opterećenja predstavlja najveći mehanički problem ovakvog sustava. U ovom radu, predstavljen je analitički model izračuna sile predopterećenja vijka i momenta otpuštanja sustava te je numeričkim modelom ispitan utjecaj pojedine konekcije na okolnu kost.

Abstract (english)

In modern dental implant prosthetics, there is a trend of using internal conical connections. Given that different manufacturers offer different taper angles, usually from 1.5° to 45°, the question of the biomechanical success of individual connections and thus of implantology systems arises. The connection between the abutment and the implant is realized by screw preload, and loosening of the screw due to cyclic loading represents the biggest mechanical problem for this type of systems. In this thesis, an analytical model for the calculation of screw preload force and the loosening moment of the system is presented. The influence of a few connections on the surrounding bone is examined with a numerical model.
