Interventions

DEVICE

V-bend Bonded Retainer

Traditional stainless steel retainer commonly bonded in the anterior teeth of the mandibular arch to maintain their alignment after orthodontic treatment.

DEVICE

Vacuum-formed Retainer

These clear retainers have the objective to maintain stable the results obtained after orthodontic treatment. They cover all the surfaces of the teeth up to the first or second molars.
