Abstract

U ovom radu analiziran je pomak krune zuba prije i nakon ortodontske terapije te je objašnjeno određivanje centra rotacije zuba koristeći personalizirane CT snimke i programski paket Mimics 17.0. Prvi dio rada sadržava teoretski dio potreban za razumijevanje provedene analize. Tu su opisane sve vrste zuba u ustima, njihova građa, koštana pregradnja uslijed pomicanja zuba te nepravilnosti u njihovom položaju. Također su spomenute naprave koje se koriste za ispravljanje nepravilnosti u položaju te sama biomehanika zuba. Drugi dio rada opisuje postupak analize personaliziranog modela zuba s okolnim tkivom od izrade 3D modela do određivanja pomaka uslijed ortodontske terapije.

Abstract (english)

In this research a tooth crown displacement before and after orthodontic treatment is analysed and determination of rotation centre using personalized CT images is explained. In the first part of the paper, theory required to understand performed analysis is explained. Also, this part contains description of all teeth in the mouth, their structure, bone remodeling due to teeth movement and irregularity in their position. The equipment used to correct irregularity in teeth position and biomechanics of tooth itself is also mentioned and explained. The second part of the paper describes analysis of personalized tooth model with surrounding tissue from the 3D model made using CT scans. It also describes application of this model to determine a tooth displacement during an orthodontic treatment.
