If you are looking at options for straightening your teeth, you might be wondering what the difference is between a retainer and Invisalign. While they both support the repositioning and alignment of your teeth, they have very different roles in this process. Today, we’re going to share our complete guide to retainer vs Invisalign treatment options and discuss when you would use both of these devices. Our team will be here to answer questions about Invisalign aligners, so don’t hesitate to get in touch with us today.
What Is Invisalign?
Invisalign is an orthodontic system that straightens teeth using a series of custom-made clear aligners. These aligners may look slightly like a retainer at first glance, which is why people often ask us what the difference between Invisalign and a retainer is. Invisalign clear aligners gradually shift teeth into their desired positions over time, using a plan created after an initial consultation with their innovative teeth-straightening technology. Unlike traditional metal braces, Invisalign clear aligners are removable, nearly invisible, and made from smooth, medical-grade plastic. They offer a discreet and comfortable alternative to metal brackets, which is why they have become so popular with both teenagers and adults.
When you choose Invisalign braces, your dentist or orthodontist creates a digital treatment plan that predicts each stage of tooth movement during your treatment. You usually will wear each set of aligners for one to two weeks, progressing through the series of aligners until your teeth reach their final alignment. The process can take several months to a couple of years, depending on the complexity of the case, and our team will be here to guide you through this process from day one through to the end of the treatment plan.
What Is a Retainer?
Continuing our comparison of Invisalign vs retainer treatments, a retainer is a device worn after orthodontic treatment. This can be used by patients who have either traditional braces or Invisalign aligners after completing the initial treatment plan. The purpose of a retainer is not to move teeth anymore, but to keep them in their new positions and maintain the work that the braces did over the past months or years. Retainers prevent what dentists call relapse, in which your teeth gradually drift back to their original alignment. This would naturally be a huge waste of your time and money that you spent on your braces, which is why the majority of patients use retainers after having braces.
There are two main types of retainers. The most common are removable retainers, which are clear plastic trays similar to Invisalign. They can also be wire-and-plastic designs, known as Hawley retainers. Some patients may need a fixed retainer. This is a thin wire bonded to the back of the teeth to provide long-term stability. Regardless of which option you go for, the main purpose of a retainer is to maintain the position of your teeth, not to move them any further.
Invisalign vs Retainer: The Key Differences
When comparing a retainer vs Invisalign braces, the main difference lies in their intended function. These are the key differences between Invisalign and a retainer.
1. Purpose of the Device
Invisalign is designed to move teeth into a new, straighter alignment. On the other hand, a retainer is designed to hold your teeth in position after treatment and prevent further movement.
2. Material and Design
While both devices tend to be made from clear plastic and look quite similar, Invisalign aligners are designed to apply precise pressure to specific teeth. They often include attachments, which are small tooth-coloured bumps that help to guide movement. Retainers are not designed to shift teeth. Their plastic is usually more rigid, and they do not rely on attachments to stay in place.
3. Duration of Use
Invisalign must be worn for 20 to 22 hours per day throughout the treatment length. Retainers are usually worn full-time immediately after treatment, then gradually reduced to night-time wear. Most people need some level of retainer use for the rest of their lives if they want to maintain results from their braces treatment.
4. Cost
Invisalign is a full orthodontic treatment, and the cost of the treatment will reflect this. It includes multiple sets of aligners, appointments to track progress, and dentist supervision. Retainers are significantly cheaper, as they are a post-treatment maintenance device rather than a corrective system and don’t require future adjustments or new trays to be created in most cases.
Your dentist or orthodontist will guide you to pick the best option based on your needs, but understanding the basics of Invisalign vs a retainer helps you to be more in control and knowledgeable about your treatment journey.
