Are bonded lingual retainers an adequate option for anterior tooth position?
Figure 1: Prepared workstation. Bonded lingual retainers provide an adequate means of maintaining anterior tooth position relatively independent of patient cooperation.
What does d8220 mean in dentistry?
D8220 Fixed appliance therapy Fixed indicates patient cannot remove appliance; includes appliances for thumb sucking and tongue thrusting. LAB FM – 35 Rev: 12/20/07 Page 3 of 4
Does bond strength differ between bonded and rebonded lingual wire retainers?
Therefore, the initial bond strength and rebond strength of lingual wire retainers using a flowable composite were determined. The hypothesis formulated was that bond strength differs between bonded and rebonded retainers.
What is a bonded lingual retainer?
A Bonded Lingual Retainer Appliance (BLR) is usually comprised of a braided stainless steel wire that connects to the lingual (back) surfaces of the front teeth. Composite resin (dental restorative material) is used to adhere the appliance to the teeth.
How long does a bonded retainer last?
The glue that bonds the wire can wear out with the everyday activity your mouth experiences—eating, talking, brushing and flossing. A bonded retainer on your upper teeth may last up to three years, while a lower bonded retainer will last longer, as this part of the mouth doesn't see as much activity.

Is a bonded retainer permanent?
A permanent retainer is a single wire made of metal or strong fiber fixed to your teeth using a special bonding agent. This wire keeps your teeth in a fixed position.
Can your teeth move with a bonded retainer?
Sometimes, when inserted, the lingual bonded retainer can be active and can slowly deliver force to a tooth over time, causing it to shift.
Can a dentist remove a bonded retainer?
Should you ever have a fixed retainer removed? Though the name might suggest otherwise, a permanent retainer can indeed be removed. The dentist or orthodontist will remove the bonding cement with a dental drill, detach the retainer, then clean and polish the teeth.
How much will teeth move without retainer?
During this time, a week without your retainer may cause some minor shifting. Your retainer may feel a bit tighter on your teeth when you place it back in again. Throughout the rest of your retention phase, it's still possible for your teeth to shift a bit if you go without wearing your retainer for a week.
Is a permanent retainer worth it?
Because teeth begin to shift naturally as we age, a permanent retainer typically offers better long-term results for teeth straightening than a removable one. You can't forget to put it in — it's already there!
What type of retainer is best after braces?
If appearance is a priority, your best options are a clear or permanent retainer. Clear retainers are virtually invisible, which means you could wear them at any time and they barely will be noticed. The same goes for permanent retainers because the wire is positioned along the back of your front teeth.
Why did I get a bonded retainer?
What Are the advantages of a bonded retainer? Bonded retainers have the advantage of remaining in place day and night without any cooperation from the patient beyond keeping them clean. They can't be forgotten and parents don't need to ask their kids if they are wearing their retainers.
Are lingual braces permanent?
Lingual braces are permanently placed on your teeth, so you don't have to remember to wear them. Invisalign is made of plastic and in some cases cannot fix severe dental issues.
Do you need to wear retainer if you have a permanent retainer?
The answer to that is almost always yes. Nearly everyone will need to wear some kind of retainer after braces. Think of permanent retainers as an insurance policy for your new smile.
How often should permanent retainers be replaced?
In short, the answer depends on the type of retainer you have. Bonded retainers, which are bonded to the back of your teeth, can last three years or more. Conversely, removable alternatives have a shorter lifespan and typically last anywhere from six months to a few years.
How often should a retainer be replaced?
A retainer is in the mouth for 6-8 hours nightly. Therefore, we recommend you replace your retainer as often as your toothbrush. Retainer Club offers plans to replace your retainers every 4,6, or 12 months. For the best performance and cleanliness, you should replace your retainers as often as your toothbrush.
Which is better permanent or removable retainer?
Because teeth begin to shift naturally as we age, a permanent retainer typically offers better long-term results for teeth straightening than a removable one. You can't forget to put it in — it's already there!
When should a plastic retainer be replaced?
If you are examining your retainer and notice that there are cracks in the plastic, it's time to order a replacement. These cracks will grow and the retainer won't have the strength needed to keep your teeth in the same place.

Abstract
There is no consensus in the literature concerning the rebonding procedure for orthodontic retainers. The aim of this in vitro study was to evaluate the bond and rebond strength of retainers bonded to enamel surfaces with and without composite remnants.
Introduction
Retention is the phase of orthodontic treatment aimed at maintaining the teeth in the corrected positions. Without the retention phase, there is a tendency for the teeth to return to their initial position ( Al Yami et al., 1999 ).
Materials and methods
The bond strength of retainers was determined on three different surfaces: clean enamel, enamel from which all composite had been removed by a tungsten carbide bur, and cured composite roughened by a tungsten carbide bur. The bond strength of the retainer was determined by means of a cantilever tensile bond strength test (TBS).
Results
The mean initial bond strength and rebond strength of the lingual wire retainers and their standard deviations are presented in Table 1. Analysis showed no statistically significant differences between the two groups ( F = 0.005; P = 0.94) and the rebonding procedures ( F = 0.360; P = 0.70).
Discussion
Clinically, the reliable bonding of lingual wire retainers is important. The bonded wire retainer is a very complex system on which forces are exerted from different directions. For that reason, shear bond strength (SBS), cantilever loads, torque, and tensile strength tests can be performed to evaluate the bond strength of the wire to the enamel.
Conclusions
A possible explanation for the difference between in vitro and in vivo results might be the clinical circumstances that influence bonding. In order to obtain ideal bonding conditions for rebonding lingual retainers, it is recommended that the bonding site is clean and dry but also free of old composites remnants.

Without the retention phase, there is a tendency for the teeth to return to their initial position (Al Yami et al., 1999).
