ABSTRACT
Introduction: Transverse discrepancies of the maxilla is one of the most prevalent skeletal problems. Due to the drawbacks of
conventional RPE and invasive surgical expansion, alternative methods were developed, such as Mini Implant-supported rapid
maxillary expanders (MARPE). Many studies reported by Haas, Davis and Kronman, Akkaya et al. regarding the maxillary response
after MARPE on the sagittal dimensions were inconclusive.
Aim: The aim of this study was to analyze the sagittal effects on the maxilla after Mini Implant assisted rapid palatal expansion (MARPE)
in adolescents.
Materials and methods: Pre-treatment CBCT images (T1) were taken as a standard initial record for all patients and post-treatment
CBCT (T2) was taken three months in retention after expansion with MARPE. The parameters SNA angle, Frankfort horizontal
plane to NA angle, A-N perpendicular in mm, ANS – PNS (in mm) were measured and calculated for evaluation of the sagittal
maxillary changes. Comparisons were then made between the two treatment groups at T1, T2 and T2 - T1.
Results: A positive increase was seen from pretreatment to post-treatment in both angular and linear measurements showing the
significant sagittal skeletal change.
Conclusion: The study found a statistically significant forward displacement of maxilla after transverse skeletal expansion in adolescent
patients with transverse problems achieved through MARPE.
