| Popis: | The aim of the study is to propose new designs of orthodontic miniplates, which were evaluated by finite element method, regarding to the distribution of stress after application of forces on them. Six three-dimensional models of miniplates were designed, in the forms of T, Y, and I with inverted hook ends and two buttons. Forces of 1N, 2N, and 3N were applied in vertical, horizontal and diagonal directions. Charging was performed. It was observed that the T-shaped miniplates were the ones that showed greater tension accumulation located in the region of the neck of the device. The "Y" shaped miniplates showed a region of tension accumulation in the neck region of the accessory only when 3N horizontal force was applied and the "I" miniplates showed good voltage distribution in all magnitudes and directions of force applied. A different distribution of forces was still observed when the activation end was changed. In general, the miniplates showed a good distribution of tensions, being a good option of skeletal anchorage in orthodontic treatments. |
