20.500.12556/DKUM-67264 Force measurements on teeth using fixed orthodontic systems Metode merenja sila na zubima kod fiksnog ortodontskog sistema The fixed orthodontic appliance consists of brackets that are bonded to the teeth. When the wire is engaged in the slot of the brackets, it generates forces for orthodontic tooth movement. The change in periodontal blood supply provides a biological response which leads to remodelling of the alveolar bone and the orthodontic tooth movement. Many variables influencing orthodontic treatment cannot be controlled fully, such as growth and tissue response to appliances. However, the force placed on the tooth should be a controllable variable, and a careful study of the physics underlying clinical applications can help in reducing undesirable side effects. The properties of orthodontic wires such as: strength, stiffness, elasticity and spring-back define their clinical usefulness. The ideal orthodontic wire should exhibit the following properties: large spring-back, low stiffness, good formability, high stored energy, biocompatibility and environmental stability, low surface friction, and the capability of being welded or soldered to auxiliaries. The ideal arch wire has not been introduced yet. Once the wire is activated or bent, it is the unloading or deactivating forces that produce the orthodontic tooth movement. For these reasons, it is necessary to know the force level caused by each individual wire used in orthodontic treatment. Finally, the purpose of this paper is a presentation of force measurements which are generated by different super-elasticity NiTi wires. Fiksni ortodontski aparat sastoji se od bravica (breketa) povezanih zubima. Nakon provlačenja kroz otvore na breketima, žica generiše silu koja utiče na ortodontsko pomeranje zuba. Promena u parodontalnom dotoku krvi predstavlja biološki odgovor koji dovodi do preoblikovanja alveolarne kosti i ortodontskog pomeranja zuba. Mnoge promenljive koje utiču na ortodontsko pomeranje zuba, poput rasta i odgovora tkiva na aparat, ne mogu da se kontrolišu u potpunosti. Međutim, sila kojom se deluje na zub treba da bude promenljiva i na nju se može uticati, a pažljivo izvedeno ispitivanje fizičke osnove kliničkih primena može da bude od pomoći pri smanjivanju neželjenih sporednih efekata. Osobine ortodontskih žica, kao što su jačina, krutost, elastičnost i spring-back efekat definišu njihovu kliničku primenljivost. Idealna ortodontska žica treba da poseduje sledeće osobine: izražen spring-back efekat, nisku krutost, dobru obradivost, visok nivo uskladištene energije, biokompatibilnost i stabilnost u okruženju, malo površinsko trenje, kao i sposobnost zavarivanja i lemljenja s pomoćnim delovima. Idealna žica za luk još nije pronađena. Kada se žica aktivira ili savije, ortodontsko pomeranje zuba vrši se pod uticajem rasterećenja ili deaktiviranja sila. Stoga je potrebno znati nivo sile koju proizvodi svaka žica pojedinačno pri ortodontskom lečenju. Cilj ovog rada je da izmeri sile nastale dejstvom različitih superelastičnih NiTi žica. force measurements orhodontic system teeth NiTi alloys merjenje sil ortodontski aparat zobje zlitine NiTi true false true Angleški jezik Srbski jezik Znanstveno delo 2017-08-09 09:00:23 2017-08-09 09:02:41 2022-08-01 13:45:08 2019-07-11 16:14:30 2013 0 0 str. 105-122 št. 2 Letn. 61 2013 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 0042-8469 620.1/.2:616.31 4423938 16932630 10.5937/vojtehg61-2960 0042-8469 URN:SI:UM:DK:XFPWJEIC Vojnotehnicki_glasnik_2013_Rudolf,_Fercec_Force_measurements_on_teeth_using_fixed_orthodontic_systems.pdf Vojnotehnicki_glasnik_2013_Rudolf,_Fercec_Force_measurements_on_teeth_using_fixed_orthodontic_systems.pdf 1 712E73DE32EA0EB4F832AE6056ACD819 1c227a6ca3dca3a760b58b83bf266a0f4f538ab5ce606e040671de6279c7563e 7eb36782-7c0e-11eb-bb7a-00155d0001ca 20.500.12556/dkum/84e35e15-1cc1-4b8c-840a-cba3e96abccb https://dk.um.si/Dokument.php?lang=slv&id=115048 http://scindeks.ceon.rs/Article.aspx?artid=0042-84691302105R 1 https://dk.um.si/Dokument.php?lang=slv&id=115047 Fakulteta za strojništvo 0 0 0
