One of the things dentists make it a point to do when removing braces from our patients is to make sure their teeth are white and attractive after all corrective devices have been taken out of their mouths.
Not only do dentists remove brackets and wires, but dentists also give patients tooth whitening trays to make sure they enjoy a cosmetic outcome to the corrective orthodontic treatment they have experienced. There are 2 different methods that dentists use for removing braces. The choice of method depends on how the treatment of the patient concludes.
If the patient is seeking an adjustment, and their teeth are exactly where they are intended to be, dentists take out the wires, make alginate impressions of both dental arches, and put the wires back in. dentists then pour the impressions and send them to the lab to make bonded retainers.
Dentists schedule an appointment for removing braces appointment in 3 weeks. When the patient returns, dentists bond the permanent retainers to their teeth. dentists then take new impressions of both arches, and schedule another appointment in 1-2 weeks.
When the patient returns, dentists give them the bleaching trays and the backup removable retainers. These retainers are made from the models dentists created using the PVS impressions, and are manufactured from .040 ortho splint material and are trimmed 2mm from the gingival margin. They work exceptionally well as back-up retainers and whitening trays.
Patients need these trays, along with take home whitening material, because after dentists finish removing braces there is always some tooth discoloration where the braces have been. Typically, 2 weeks of cosmetic teeth whitening at home removes this discoloration.
Sometimes, however, a patient comes in when their teeth are almost in perfect alignment. Before removing braces in these instances, dentists have to make the necessary adjustments first. Normally, dentists give the patient approximately 1 month for these adjustments to take effect. The patient the patient returns, and after dentists have completed removing their braces, dentists take out any cement or pieces of bracket that remain attached to their teeth.
Dentists then polish their teeth and deliberately leave the majority of the bonding material in place. This glue acts like a reservoir for custom bleaching when dentists pour the models. dentists take impressions, pour the models with a material called stat stone that sets in 5 minutes, and dentists make the removable bleaching/retainer trays while the patient is in the offices.
While the retainers are being made, the rest of the glue is polished off of the teeth. The patient leaves the office with their removable retainers, whitening trays, and material. A follow up is scheduled in 2-3 weeks for the patient to have their bonded retainers placed.
The PVS impressions are then sent to the lab for the fabrication of the bonded retainers. When the patient returns, the bonded retainers are placed. After this, the removable retainers can now be trimmed on the lingual from canine to canine to fit over the bonded retainers.
