Abstract
Unatoč mnogobrojnih istraživanja velikog broja autora, pojava patološke abrazije u nekim aspektima nije dovoljno razjašnjena. Trošenje tvrdih zubnih tkiva koje prelazi granicu fiziološkog dovodi do oštećenja zuba kao organa, njegovog poitpomog aparata odnosno cijelog stomatognatog sustava. Nesumnjivo je da će takovo patološko oštećenje zuba imati odraza na postignute vrijednosti žvačnih sila, a da će abradirani zub biti funkcionalno opterećen različito u odnosu na zub iz kontrolne skupine ispitanika. Stoga su provedena gnatodinamometrijska ispitivanja na odgovarajućem uzorku ispitanika s kliničkom slikom patološke abrazije i kontrolnoj skupini ispitanika bez abrazije. Analizom rezultata ustanovljeno je da je pojedini zub frontalnog segmenta abradiranog zubala opterećen s 10,97% manjom silom od frontalnog zuba neabradiiranog zubala, abradirani zub desnog segmenta 1 0 ,8 8% većom silom i abradirani zub lijevog segmenta 13,96% većom silom.Despite numerous studies of the subject, some aspects of pathologic
abrasion appear to require more clarification. Wearing away of the hard dental tissues exceeding physiological limits damages the teeth as an organ, and its supporting structures as well, i. e. he entire stomatognathic system. Such a pathologic lesion to the teeth would unavoidably reflect upon the masticatory force values attained, while the functional load exerted on an abraded tooth would differ from that acting upon the control group teeth. Therefore, he gnathodynamometric studies were undertaken in a representative sample of subjects with clinical picture of pathologic obrasion and a
control group of abrasion-free subjects. According to the results, the masticatory force acting upon individual abraded teeth of the frontal, right and left segments was by 10.97% lower, 10.88% higher and 13.96% higher compared to the load exerted on the respective non-abraded teeth, respectively
