Force measurements on teeth using fixed orthodontic systemsRudolf, Rebeka (Avtor) Ferčec, Janko (Avtor) force measurementsorhodontic systemteethNiTi alloysThe 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.20132017-08-09 09:00:23Znanstveno delo67264ISSN: 0042-8469UDK: 620.1/.2:616.31OceCobissID: 4423938COBISS_ID: 16932630DOI: 10.5937/vojtehg61-2960ISSN pri članku: 0042-8469NUK URN: URN:SI:UM:DK:XFPWJEICsl
