لخّصلي

Este método de fabricación e inserción (Sridhar, 2015) implica fijar bandas en los primeros molares permanentes o segundos molares deciduos. Se suelda un arco lingual pesado (alambre 0.40) doblado a 45° al paladar y a las bandas molares, añadiéndole otro alambre para crear una barrera mecánica para el dedo, sin afectar la oclusión. El diseño debe evitar el contorno palatal para mantener la eficacia. Tras el cementado, se dan instrucciones de higiene oral, crucial por la acumulación de comida que puede causar halitosis e inflamación gingival. El uso del aparato dura unos 6 meses; la desaparición del hábito suele ocurrir en la primera semana, aunque se recomienda un mínimo de 3 meses para prevenir recaídas. En casos de recaída o hábitos combinados, se ajusta la duración o el diseño del aparato.

Fabrication and insertion (Sridhar, 2015):
1- The bands are fixed on the permanent 1st molars or deciduous 2nd molars.
2- A heavy lingual arch (0.40wire) is bent to 45° to fit passively in the palate
and is soldered to the molar bands.
3- Another wire is soldered on to the first wire to form a crib or mechanical
obstruction for the digit and this should not interfere with the normal21
occlusion.
4- Should not follow the contour of the palate, if the suction and kinesthetic-
neuromuscular gratification are to be rendered meaningless.
5- Post-insertion instructions should be given after the appliance is cemented
and inserted.
6- Maintaining good oral hygiene is essential as the appliance collect the food
easily and results in halitosis and gingival inflammation.
7- The duration of appliance wear is approximately 6 months.
8- In about 3 months the habit absences completely which is a good indication
against a relapse. In most instances, the habit will abandon after 1st week of
appliance wear.
9- If there is a tendency toward relapse of the habit, it is essential to leave at
least a partial appliance in place for a longer time, or if there is a
combination of habits it is necessary to modify the appliance in length
duration of the treatment.
