Abstract

Transverse maxillary deficiency currently affects 8–23% of adults. One of the most widely used orthodontic treatments today in patients with transverse maxillary defects is the maxillary skeletal expander (MSE). This was a retrospective observational imaging study regarding structural bone changes that may occur during healing after the placement of micro-implant assisted rapid palatal expanders (MARPE) in combination with cortico-puncture (CP) therapy. Regarding the magnitude of the mid-palatal suture opening, the mean split at the anterior nasal spine (ANS) and the posterior nasal spine (PNS) was 3.76 and 3.12 mm, respectively. The amount of split at the PNS was smaller than at the ANS, approximately 85% of the distance, showing that the opening of the midpalatal suture was almost parallel in the sagittal plane. On average, one-half of the anterior nasal spine (ANS) moved more than the contralateral by 0.89 mm. In the present study, we show that MARPE associated with CP therapy had a positive outcome on the midpalatal suture opening. This occurred in safe conditions, without post-surgery bleeding, and showing healing at the corticotomy level, with no signs of swelling or sepsis, which are side effects usually associated with more complex surgical treatments. Our results suggest that non-surgical palatal expansion, assisted by MARPE and CP, is achievable and predictable in young adults.

Our study demonstrates the use of CP therapy as a surgical method for accelerating bone remodeling to complement the micro-implant assisted rapid palatal expanders (MARPE) technique to facilitate suture split

Summary

Introduction

Transverse maxillary deficiency currently affects 8–23% of adults and adolescents [1].One of the most widely used orthodontic treatments today in patients with transverse maxillary defects is the maxillary skeletal expander (MSE) [2]. Transverse maxillary deficiency currently affects 8–23% of adults and adolescents [1]. The possibility of using these micro-implants at the level of the palatal region is favored by the gingival mucosa at this level having favorable elasticity [3]. It can affect the health of these patients over time In this sense, modifications of the occlusal plane, damage to periodontal structures, gingival retraction, change in tongue position, asymmetry of the facial planes, and, in severe cases, even sleep apnea syndrome may occur in these patients.
