Surgically assisted rapid maxillary expansion: long-term stability. The expansion can be no faster than the palatal bones and soft tissues can adapt to the powerful forces generated by the Haas expander, because the palatal suture does not separate in these mature patients. In our series of 47 adults, we prescribed a quarter turn every day, but it became clear that this schedule was too rapid. Braces are a common orthodontic appliance used to treat a variety of dental issues. However, the increase in palatal volume will be greater and the gingival recession on the molars and bicuspids will be less with the surgical assist.

The Anterior Growth Guidance Appliance serves as an artificial tongue. Even for an adult, the body responds to this soft tissue stimulus by depositing bone throughout the face. The appliance provides a subtle stimulus to soft tissue in the maxilla (upper jaw). (In adults, I now activate no more frequently than every other day and, often, every third to fifth day. Not 1 molar or premolar relapsed into crossbite. The AGGA is simply the gateway into this cycle. Data on long-term stability are difficult to obtain because patients must be recalled for records many years after the completion of their treatment. The results found that the width of the palate increased similarly between the adult and child subjects, and the correction of posterior crossbites was stable and successful after discontinuing treatment. }, author={C.

However, when the evidenced-based literature demonstrates success in nonsurgical transarch expansion in adults, it is time for a paradigm shift. The RPE is attached to the upper molars using bonding or cemented bands. RPEs are used often to correct posterior crossbites. Activation of the expansion screw at the rate appropriate for children will cause unacceptable palate swelling and pain in adults. Since we are separating a mid palatal suture, it is better to do this procedure at a younger age before the palatal suture becomes fused. Many websites will tell you that palate expansion for adults is impossible because the palate sets at puberty. The concept that nonsurgical palate expansion in adults can be successful has been hotly debated in the orthodontic community. To begin this article with no ambiguity: Adult palate expansion without surgery is not only possible, but normal and expected. ( Log Out /  While still taught this way in most academic institutions and preached by the medical mainstream, thousands of orthodontists and dentists have attempted non-surgical intervention on patients into their 20s, 30s, 40s, 50s, and later yet found that there is no age at which the skull bones will not adapt and expand with pressure. This gives your tongue the space it needs, and which it never had, to function properly. The function of breast feeding causes an infant to develop the habit of pressing the tongue up against the roof of the mouth both at rest and during activity. Down the middle of the palate is the mid-palatal suture, in the front is the premaxillary suture, and in the back is the transverse palatine suture. Call and schedule a consultation to see which you are a candidate for. By nature, humans are supposed to breath from their noses.
