Nance appliance is one of several types of dental appliances used to treat sleep apnea. Developed by Robert Nance, DDS, MD, the Nance appliance is designed to keep the airway open during sleep through non-invasive and removable means. The device works by moving the lower jaw forward slightly while keeping the tongue in place at the roof of the mouth. This encourages breathing through the nose and prevents snoring. Here are answers to some frequently asked questions about nance appliances, including what they are, how they work, and who can use them.
Introduction
Lower lingual holding arch appliances help create space in our mouths. For example, when a lower lingual retainer is placed on teeth that are crowded, there’s often an insufficient amount of space for our tongue to rest comfortably. When too much pressure is placed on our tongue—or it’s too cramped for too long—we begin to experience discomfort, which can lead to soreness and discomfort. In order to remedy these issues, we might use a lower lingual holding arch, or nance appliance, which helps reduce jaw tension and redistribute pressure from our tongues. Because these devices are often only used during certain times (such as when you sleep), they come in two major varieties: removable and fixed. Both options can be customized to fit your needs.
A Brief History of the Nance
The nance appliance was developed by dentist Henry Nance in 1916. Dr. Nance discovered that when an upper canine tooth is forced into lingual occlusion with another incisor, it serves as a powerful tongue restrainer. Many years later, orthodontist O.C. Burton refined its design to use molars instead of canines as anchorage teeth for a more effective holding action against the lingual surface of opposing incisors. Today, we use lower lingual holding arches (LLHAs) because they work better than canines to hold down tissue during retraction of maxillary or mandibular dentition—and they don’t traumatize permanent teeth!
Its Role in Orthodontics
The major goal of using a nance appliance is to align the lower jaw. The appliance creates pressure on the lower molars that helps move them into place, which in turn encourages proper jaw growth and development. This can help reduce bite problems that may cause pain or discomfort for patients throughout their day-to-day lives. If your orthodontist determines you need to wear a nance appliance, your dentist will refer you to an orthodontist who specializes in nance appliances. During your consultation, they'll assess if it's something that will work with your treatment plan.
Does My Child Need One?
If your child has torticollis, an expert may recommend you try applying heat, massage therapy, or stretching to help loosen tight muscles. If that doesn’t work, then a Nance appliance might be prescribed. Your doctor will want to make sure that your child’s airway is clear before prescribing any treatment. She will also want to be sure that there are no underlying issues causing pressure on your child’s neck. All of these elements should be considered before prescribing any treatment for torticollis; in some cases, none of them might be necessary at all! But if you find that nothing else is working for your child—or if another application for alternative treatments is recommended—then consider applying for a Nance appliance as one last option.
Getting an Aligner Instead
As an adult, you are responsible for creating your own treatment plan. Your orthodontist will recommend what he or she thinks is best for you, but ultimately it’s up to you to decide which treatment will be most effective. The most important thing to remember is that healthy teeth are more important than straight teeth—so if your orthodontist recommends something that seems overly harsh, be sure to check his or her reasoning and ensure it’s in your best interest. Here are three examples of common orthodontic appliances
Working with Your Orthodontist
Before getting braces, you will be required to see an orthodontist. In order to make sure that your treatment runs smoothly, it’s best to work with your orthodontist every step of the way. The initial consultation is very important in order for you to discuss any concerns or questions you may have, as well as what treatment options are available to you. An exam will also be performed in order for your orthodontist to determine how your teeth are aligned at present, so they can evaluate where you need assistance in terms of alignment and tooth length/positioning issues. After all of these steps have been taken care of, it’s time for dental impressions!
