This guide explains what it is, when it is used, and how to manage it.

A Nance holding arch — often called a Nance appliance or Nance palatal arch — is a fixed orthodontic device fitted in the upper arch. It consists of a stainless steel wire that runs from molar bands on the upper first molars, arches across the palate, and is anchored by a small button of acrylic resin that rests against the roof of the mouth (the palate) just behind the upper front teeth. The acrylic button distributes the forces of retention across the palatal tissue, preventing the molar bands from moving forward. Because it is fixed in place — cemented onto the molar teeth — it does not rely on a patient wearing or carrying a removable device, which makes it particularly well suited to younger patients or situations where compliance cannot be guaranteed. ## Purpose and when it is used The primary purpose of a Nance appliance is to prevent mesial drift — the natural forward movement of upper permanent molars into space that has been created earlier in the arch. This commonly arises in two situations. The first is early loss of primary (baby) molars due to decay or extraction before the permanent teeth are ready to erupt; the Nance arch holds the space open so the permanent premolars can erupt correctly. The second is during orthodontic treatment itself, where a Nance arch is used as an anchorage device to prevent upper molars from moving forward in response to the forces applied to move front teeth. In the latter context it acts as a passive anchor while other teeth are being repositioned. It is most commonly used in children and young teenagers but can be applied in adults when anchorage is critical. ## Fitting process Fitting a Nance holding arch is a straightforward two-appointment process in most cases. At the first appointment, the orthodontist takes impressions or digital scans of the upper arch and fits separators (small elastic rings) between the upper first molars to create space for the molar bands. A week or two later, the bands are tried in, the appliance is fabricated by an orthodontic laboratory, and at a third appointment the cemented appliance is fitted. The wire is shaped to the palatal contour and the acrylic button is positioned to rest flat against the palate without pressing on the gum tissue or anterior teeth. The molar bands are cemented with glass ionomer cement. The procedure is painless, though the patient may feel mild pressure and slight awareness of the new appliance for the first few days. ## What to expect when wearing it Most patients adapt to a Nance appliance within one to two weeks. Initially, speaking may feel slightly different — particularly sounds that require the tongue to contact the palate such as d, t, n, and l — but speech usually normalises quickly as the tongue adjusts. Eating is generally unaffected, though extremely hard or sticky foods should be avoided. The acrylic button is designed to sit passively against the palate and should not cause ongoing pain. Some patients notice that food collects around the button and along the wire, which is why specific hygiene measures are essential. ## Hygiene care The most common hygiene challenge with a Nance appliance is cleaning around the acrylic palatal button, which has irregular edges that can trap plaque and food debris. After every meal, rinse the mouth with water to dislodge loose debris. Twice daily use of a soft toothbrush angled towards the palate can reach around the button. An interdental brush or WaterFlosser directed at the button and the molar band edges is particularly helpful. Avoid carbonated and sugary drinks during treatment. The gum tissue beneath the button must be kept clean — a red, inflamed, or tender area of palate around the button is a sign of inadequate hygiene and should prompt more careful cleaning and a check appointment. If food compaction repeatedly causes discomfort, your orthodontist can adjust the button. ## Palatal ulceration and other complications The most frequently reported complication of a Nance appliance is palatal ulceration — a sore spot or small ulcer developing on the gum tissue beneath or around the acrylic button. This most commonly occurs in the first few weeks as the tissue adjusts, or if the button has been positioned slightly too close to the gum. Mild cases resolve without intervention if hygiene is maintained; persistent or painful ulcers should be assessed by the orthodontist, who may relieve the button slightly. If the cement seal on a molar band fails, the band can become loose, which removes the appliance function and may cause the wire to shift and irritate adjacent soft tissue. A loose band should be reported promptly. Rarely, the acrylic button can fracture if the patient bites on something very hard. ## How long the Nance arch is worn The duration depends entirely on what the appliance is being used for. As a space maintainer after primary tooth loss, the Nance arch is typically worn until the permanent premolars are sufficiently erupted and the molar has no path to drift — this can range from several months to two or more years depending on the developmental stage. As an anchorage device during active orthodontic treatment, it is worn for the duration of the tooth-movement phase and removed when anchorage is no longer needed. Your orthodontist will review the appliance at each appointment and will advise when removal is appropriate. Removal is simple and painless: the cement is loosened with a special instrument and the bands are gently removed. ## What happens if the cement fails If the molar band cement fails and the appliance becomes loose, contact your orthodontist or dentist as soon as possible. A loose Nance appliance is no longer providing retention and the molars can begin to drift within weeks. Do not attempt to remove the appliance yourself, as the wire can damage adjacent teeth or soft tissue if pulled incorrectly. If the wire end is sharp or the loose appliance is causing irritation, use orthodontic wax to cover the affected area temporarily. At the repair appointment the band will be recemented or replaced as needed. ## Useful related pages [Space Maintainer for Children UK](https://virtualconsultant.online/guides/space-maintainer-children-uk) [Palatal Expander UK](https://virtualconsultant.online/guides/palatal-expander-uk) [Interceptive Orthodontics UK](https://virtualconsultant.online/guides/interceptive-orthodontics-uk) [Over-Retained Baby Teeth UK](https://virtualconsultant.online/guides/over-retained-baby-teeth-uk) This guide is for general information only.

A Nance holding arch is a fixed orthodontic appliance cemented to the upper back molar teeth. A wire crosses the roof of the mouth and connects to a small acrylic button that rests against the palate. Its purpose is to prevent the upper molars from drifting forward and losing space needed for other teeth to erupt correctly. Does a Nance appliance hurt? Fitting is painless. You may feel mild pressure and awareness of the appliance for the first few days, and speech may feel slightly altered temporarily. Palatal ulceration — a sore spot under the button — is the most common discomfort and usually settles within a few weeks. If pain persists, contact your orthodontist. How do I clean a Nance appliance? Brush around the acrylic palatal button with a soft toothbrush angled towards the palate after every meal and twice daily. Use an interdental brush or water flosser to clean around the molar band edges. Rinse with water after meals to dislodge debris from around the button. How long is a Nance arch worn? This depends on its purpose. As a space maintainer it is worn until the permanent teeth are sufficiently erupted — potentially one to two or more years. As an anchorage device during active brace treatment, it is worn for the active tooth-movement phase only. Your orthodontist will advise based on your specific treatment. What if my Nance arch comes loose? Contact your orthodontist promptly. A loose appliance is no longer working and the molars can drift within weeks. Do not remove it yourself — a loose wire can cause injury. Use orthodontic wax to cover any sharp or irritating edge while you wait for your appointment. Will a Nance appliance affect my speech or eating? Most patients adapt within one to two weeks. Speech may feel slightly different at first, particularly sounds that require the tongue to touch the palate, but this normalises as the tongue adjusts. Eating is generally unaffected, though very hard or sticky foods should be avoided to protect the molar band cement and reduce the risk of the appliance becoming loose.
