The effect of orthodontic anomalies on the occurrence and severity of attrition was studied in a group of 610 subjects of both sexes, aged 3- 6 years. Attrition was recorded on biting surfaces of lateral teeth and classified into four degrees according to own classification. With the exception of crowding, attrition was more expressed in dysgnathic subjects, while in the subjects with crossbite and class III anomalies it was found to be most prononced. It is quite likely that the effect of orthodontic anomalies on the occurrence and severity of attrition results from alterations in occlusal relations and impaired function of the dentition in general.

Na uzroku od 610 ispitanika, oba spola, ispitan je utjecaj ortodontskih anomalija na pojavu i intenzitet atricije. Istraživanje je provedeno na ispitanicima od 3— 6 godina starosti. Atricija je registrirana na griznim plohama lateralnih zubi, a vrednovana je s tri stupnja vlastite namjenske sheme. Osim kod kompresijskih anomalija, atricija je izraženija kod disgnatih ispitanika. Najjače je izražena u ispitanika s unakrsnim zagrizom i anomalijama progenog kompleksa. Utjecaj ortodontskih anomalija na pojavu i intenzitet atricije vjerojatno proizlazi iz promjena okluzijskih odnosa i poremećene funkcije.
