| Summary: | Background: One of the most common maxillary abnormalities is transverse deficiency, which
can be a contributory factor in malocclusions. There are some evidence of successful non-surgical
treatment of this type of discrepancy after puberty by using maxillary expansion techniques. The
Miniscrew-assisted rapid palatal expander (MARPE) method is a newly introduced method that
has attracted the interest of many orthodontists. This study aimed to evaluate the therapeutic results
of this technique in a systematic review.
Materials and Methods: In this study, various databases including PubMed, Scopus, and
ISI (Web of science) were queried with proper keywords, provided by PICO strategy of research,
from 1980 to December 2020. Relevant articles were collected with restrictions on the English language.
The full text of papers with all inclusion criteria was assessed. The therapeutic outcomes of
MARPE were evaluated in the selected studies.
Results: A total of 14 studies were included in the systematic review. Totally, 5 case report studies,
8 retrospective studies, and 1 case series study were reviewed. Cone-beam computed tomography
was used as an outcome measure in all studies. In all reviewed studies, maxillary expansion
occurred with high success rates in patients. Moreover, respiratory characteristics were also assessed
in two studies measuring respiratory muscle strength, airflow and nasal and nasopharyngeal
airway volume, showing benefits of MARPE. A study also examined three-dimensional soft tissue
stereophotogrammetry. Based on these studies, the indication for using this method was a maxillary
transverse deficiency as well as upper and lower arches crowding. No serious complications
were reported in any of the reviewed studies. However, most studies did not perform long-term
follow-ups and the age range of the subjects was mainly between 12 and 24 years. MARPE has
been suggested as a treatment modality for correction of maxillary transverse deficiency in young
adults but patients under the age of 14 may also benefit from this treatment in special conditions.
Conclusion: A general review of the results of studies showed the high efficiency of MARPE
technique in correcting maxillary transverse deficiency.
