What type of appliance is used to expand a narrow palate?
Table of Contents
A rapid palatal expander (RPE) is a specially made appliance used to widen the two halves of the top jaw, also known as the palate or maxilla. The two halves are joined together by a “suture” in the center of the roof of the mouth.
What is SARPE in orthodontics?
SARPE is an orthodontic technique that is used to expand the maxillary arch. This technique includes treatments from both Oral and Maxillofacial Surgery and Orthodontics. This procedure is usually completed in adult patients with maxillary sutures that are fused and cannot be expanded using other techniques.
What is a maxillary expansion appliance?
Maxillary expansion is used to correct crossbites and also will create more space for crowded teeth. The expander appliance is attached to the molar teeth and is usually worn for 4-6 months. The expansion appliance is custom made for each patient and attached to the teeth with a dental adhesive.

How long does expander stay in after SARPE?
The expander will typically stay in the mouth after the expansion has been attained for about three months, at which time it is removed.
How much does Expander cost?

Cost. Traditionally the price range of a palate expander treatment plan falls around $2,000 – $3,000 minimum. Nevertheless, the total cost varies according to where you live, who your orthodontist is, and whether or not you’re covered by insurance.
Is there an alternative to an expander?
A more effective, simpler, and less costly alternative than a palatal expander is to use an appliance called a space maintainer. Interestingly, baby molars are larger in size than the permanent premolars that replace them. A space maintainers holds the extra space that is left when the baby teeth fall out.
How is Sarpe performed?
How is a SARPE performed? A SARPE is performed under general anesthesia. The surgeon will perform a vertical osteotomy (or a cut in the bone) in the maxilla, in conjunction with a Le Fort I osteotomy to perpetuate expansion of the palate.
When is Sarpe indicated?
INDICATIONS FOR SARPE 1. To increase maxillary arch perimeter, to correct posterior crossbite, and when no additional surgical jaw movements are planned. 2. To widen the maxillary arch as a preliminary procedure, even if further orthognathic surgery is planned.
Is palate expander necessary?
A Crossbite – A crossbite often occurs because the upper jaw is too narrow to fit properly with the lower jaw. This causes some of the bottom teeth to bite outside of the top teeth. While patients can have an anterior crossbite or posterior crossbite, a palate expander is typically needed to fix a posterior crossbite.
Will palate expander change face?
Does Palatal Expander Change Face Shape? Palate expander will not make your face wider. However, if you have a facial asymmetry associated with posterior dental cross bite, then palatal expander can improve your facial asymmetry.
How much can SARPE expand?
With SARPE the mean maximum expansion at the first molar was 7.48 ± 1.39 mm and the mean relapse during post-surgical orthodontics was 2.22 ± 1.39 mm (30%). At the maximum, 3.49 ± 1.37 mm skeletal expansion was obtained, and this was stable, so the average net expansion was 67% skeletal.
How painful is a palate expander?
Palatal expanders do not usually cause pain. Some patients, however, experience difficulty in speaking and swallowing for the first few days of treatment. Following your dentist’s instructions for adjusting your palatal expander will help ensure there is minimal pain and to avoid delays in your treatment plan.
