 es Distalizador de molares superiores con pistones de níquel-titanio. Informe de un caso
Prato, Rafael J.

Resumen

Para distalizar los molares superiores en pacientes con maloclusiones clase II, se han utilizado diversos aparatos. Se ha visto que la mayoría de ellos tienden a rotar e inclinar las coronas de los primeros molares. En este trabajo se presenta un aparato fijo capaz de distalizar los molares con muy poca rotación e inclinación, que no requiere el uso de fuerzas extra-orales. La aplicación de fuerzas ligeras y constantes mediante pistones de níquel-titanio optimizan los movimientos y disminuyen el tiempo de tratamiento. Otra ventaja de este dispositivo reside en que por estar cementado no se necesita cooperación por parte del paciente.

 en Molar distalizer with nickel-titanium pistons. A case presentation

Abstract

Various devices have been used to distalize upper molars on class II malocclusion patients. It has been noted that most of those devices tend to incline and rotate first molars’ crowns, because of the force applied on them. This presentation introduces a fixed device that is able to move distally upper molars with reduced rotation or distal inclination. Therefore, the use of extra-oral forces would be minimized. Constant low intensity forces applied by the nickel titanium’s open spring piston optimizes movement and decreases treatment time. Another advantage of this specific device is the fact, that it is bonded, so patient’s high degree of cooperation is no a requirement for upper molars distalization treatments.
