What is rapid maxillary expander?
What is rapid maxillary expander?
Rapid Maxillary Expansion (RME) is an orthodontic technique used to widen your upper jaw when it is too narrow. It involves the use of an expander appliance that is fixed to your child’s upper teeth and cannot be removed.
How does rapid maxillary expansion work?
How does the RME work? Your upper jaw bone forms in two halves. The RME moves these two halves apart and holds them there while new bone fills in the “gap” under the gum. As the RME widens the upper jaw, a temporary gap often appears between the two front teeth.
When do we use RME?
INDICATIONS/CONTRAINDICATIONS OF RME Rapid maxillary expansion is indicated in cases with a transverse discrepancy equal to or greater than 4 mm, and where the maxillary molars are already buccally inclined to compensate for the transverse skeletal discrepancy.
Is RME a functional appliance?
Rapid maxillary expander (RME) is a non-removable functional appliance used in cases of narrow maxillary jaw. It is effective at the spurt of growth. RME fixates on the teeth (for younger patients) or microimplants.
What does a rapid palatal expander do?
One of the common dental appliances used by dentists on growing children is the rapid palatal expander (RPE). It is used to expand the palate and to correct the bite that either has a crossbite (“opposite” bite) or a narrow upper arch. It widens the upper jaw to create space for permanent teeth.
Is maxillary expansion painful?
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.
What is Haas appliance?
The Haas appliance is a tooth-borne tissue-activated/acrylic alternative to the Hyrax appliance. Studies have indicated the Haas appliance with palatal acrylic will reduce the tipping effect on the teeth and provide a larger sutural displacement when used as a rapid expander, compared to the Hyrax.
What is a hyrax orthodontic appliance?
Rapid Palatal Expander (Hyrax Appliance) Attached to the upper molars through bonding or by cemented bands, the Rapid Palatal Expander is an orthodontic device used to create a wider space in the upper jaw.
What is a RME appliance?
What is a Rapid Maxillary Expander (RME) expansion appliance? It is termed a “Rapid” expander because it widens the upper jaw in less than 30 days. During this time, the expander actively pushes on both sides of the top back teeth to expand the jaw.
What is rapid palatal expansion?
Rapid Palatal Expansion or RPE Upper jaw expansion is a form of orthodontic treatment that is used in specific cases. By widening the circumference of the palate, the perimeter of the dental arch increases to create more space for teeth growth.
What is the purpose of semirapid maxillary expansion?
A new approach, namely, semirapid maxillary expansion (SRME) was introduced with the hypothesis that SRME may stimulate the adaptation process in the nasomaxillary complex and thus would result in reduction of relapse in the postretention period.
When to use Rapid Maxillary Expansion ( RME ) protocols?
In rapid maxillary expansion (RME) protocols, a twice-daily activation schedule, which is most commonly proposed in the literature, was shown to produce residual loads during early treatment (Zimring and Isaacson, 1965).
What kind of splint is used for maxillary expansion?
A splint type tooth- and tissue-borne modified bonded RME appliance was used, with the patients activating the screw two-quarter turns per day for the first week, followed by one-quarter turn every other day in the SRME group and two-quarter turns per day throughout treatment in the RME group.
What was the average age of maxillary expansion?
The study sample consisted of 40 individuals, 20 orthodontic patients who required maxillary expansion and 20 control cases who received no orthodontic treatment. The mean ages were 14.57 and 13.83 years at the start of treatment and control periods, respectively, and ranged between MP3cap and Ru hand-and-wrist maturation stages.
