The use of braces for the correction of single tooth position in some cases seems to be impractical, since it may cause a violation in the position of the adjacent teeth, which are used as a support for such correction. An alternative way to move of single tooth into the normal position is use of device with permanent Nd-Fe-B magnets. This allows to localize the force action and achieve the desired aesthetic and functional result with fewer side effects and also reduce the cost of treatment.
The aim of present work was development of methods and normalization of position of upper jaw canine by using the device with permanent Nd-Fe-B magnets.
Materials and methods. To move the tooth, the permanent Nd-Fe-B magnets of size 5×5×2 mm were used. An anti-corrosion ZrO2 coating was applied to the surface of the magnets. One of them was installed in a plastic devise, and the second one was fixed on the tooth using photopolymer material. The magnitude of acting force was determined using the experimentally derived dependence of the force of attraction or repulsion of magnets on the distance between them. Additional control of the interaction forces between the magnets, both at the beginning of treatment and at individual stages, was carried out using a teslameter and recalculation tables.
Results. The article provides a description of the technique and stages of manufacturing of device with magnets, as well as the procedure for attaching the magnet to the tooth surface. There was presented a clinical case of moving an abnormally located canine using a device with permanent Nd-Fe-B magnets. As a result of orthodontic treatment performed using a permanent magnet device, a vestibular displacement of the tooth 23 was performed in order to achieve normal overlap in the transverse plane. The proposed method of orthodontic treatment allowed in a short time to normalize the position of tooth 23 without side effects for the remaining teeth.
Conclusions. On the base of treatment it was proved the possibility of moving individual tooth using the device with Nd-Fe-B permanent magnets without the occurrence of side effects for supporting teeth, which allows expanding the range of traditional bite correction methods
