Abstract
Mini-screw Assisted Rapid Maxillary Expanders (MARME’s) have become a popular alternative to SARME in the treatment of maxillary constriction in adult patients. This study’s objective was to evaluate the effectiveness of a traditional RME appliance to achieve a successful separation of the maxillary midpalatal suture (MPS) at different ages, pubertal status, months past puberty, and gender. Additionally, we explored whether effectiveness can be improved by utilization of a mini-screw assisted RME appliance. 115 subjects (mean age of 13.6 years; range 7.6-29.2) were treated with traditional two or four banded traditional RME appliances, and 25 subjects (mean age of 16.9 years; range 13.1-22.6) were treated with MARME’s. 73% of the traditional RME subjects and 100% of the MARME subjects had a MPS split (p= 0.001). Post-pubertal patients ≥15 years of age treated with traditional RME had a 52.2% chance of achieving a MPS split, compared to 100% success rate seen with TAD RME treatment (p < 0.001). Utilizing a MARME rather than a traditional RME can greatly improve a clinician’s chances of achieving a MPS split if the patient is post-pubertal and/or ≥15 years of age.

- Public Abstract (ETD)
Having a narrow upper jaw can affect the bite by causing a crossbite of the back teeth. Primary treatment consists of rapid maxillary expansion, which is the widening of the upper jaw by use of an expander attached to the upper teeth. This is most effective in children. Treatment of adults has consisted of surgery. A new non-surgical approach to treatment of adults is attaching bone screws to the expander. This study was designed to compare effectiveness of the traditional expander with the bone screw supported expander at various ages and levels of maturity. The traditional expander is most effective on younger and immature patients, whereas the bone screw supported expander should be utilized on older and more mature patients.
