By widening the jaw, expansion may create more space to align crowded teeth. This appliance is simply bonded to a part of the surface of the posterior teeth using the same composite as the one used to make “white” dental restorations (“white fillings”).

(A and C) 7-year-old young patient with a posterior crossbite (arrow) caused by a narrow maxilla. These preliminary corrections will have to be followed by more complete corrections (using braces) a few years later when the permanent dentition is completed, but this preliminary intervention re-established the balance between the jaws and eliminated a functional mandibular shift. (A) When a space (diastema) is already present before the beginning of rapid maxillary expansion, the opening of the space between the teeth will be more significant. However, it is sometimes possible to see teeth, mostly the central incisors, have a different position after expansion. Ensure to clean the appliance well when you brush your teeth after each meal. (C) 2 months after removing the appliance, the excess in expansion starts to decrease. After expansion, the posterior crossbite is corrected (arrow), the maxillary arch is wider and the chin has shifted toward the middle, thus eliminating the asymmetry. This will be corrected during a subsequent step. To see how this appliance is installed, follow the link below.

(A) Malocclusion with a left posterior crossbite (arrows) caused by maxillary constriction. (D) After 5 months, the maxillary arch width is normal, the crossbite is corrected, the midlines are aligned and the mandible is centered. While palatal expansion can be done before the … The example below is of a 7-year-old young boy who suffered from. (C) After more than one year and once the eruption of the permanent teeth is completed, the occlusion is functional and esthetically acceptable. This may be useful for patients who have a more limited opening of the mouth or if you have a hard time with a standard key. The expander stays in the mouth. The interference may sometimes be adjusted by polishing the tips of the teeth if this causes discomfort to the patient. A significant space will appear between the upper central incisors during expansion.

The activation period can last from 2 to ± 3 weeks and will result in activating the screw between 40 and more than 50 times. (C) After alignment of the incisors with the expander in the mouth. The midlines remain aligned. Adding extra turns could damage your jaws, teeth, or gums, and result in extra dental work. (C) At the end of expansion, overcorrection that makes the upper teeth “go over” the lower teeth is seen on each side (more on the side where there was no crossbite to begin with). Example showing that crossbites do not “auto-correct” with time, years and growth. An expander is a quite bulky appliance that impinges on the available space for the tongue in the mouth. (A) 9-year-old young girl showing a bilateral posterior crossbite (arrows) caused by a significant constriction of the upper maxilla (B). These movements are caused by the, Although such variation in the position of teeth may cause a small esthetic damage in some rare cases, this usually does not cause any functional problems. There is no space between the upper central incisors before the beginning of expansion. Particular care must be taken for the gum (width and thickness) when expansion (regardless of the method used) is planned. This will disappear rapidly. This palatal expander chart is a guide or calendar to keep track of how many turns you have made in the expander.
