Miniscrew-assisted rapid palatal expansion (MARPE) has added a new dimension to the world of orthodontics with its use in skeletal expansion of transverse problems in adult population. However, there are few limitations noted with the use of prefabricated MARPE designs such as adaptation to the palate or minscrew fit in cases of high arched palate, which compromises with the anchorage and final outcome. The aim of this article is to use digital workflow to 3d print a MARPE with the aid of cone beam computed tomography, which would overcome the deficiencies of a prefabricated MARPE design and would provide greater rigidity and anchorage value, and predictable skeletal expansion.

The aim of this study was to compare the three-dimensional dentoskeletal effects of Haas-type and Hyrax-type expanders using primary teeth as anchorage for rapid palatal expansion (RPE). Thirty-four subjects in mixed dentition were divided according to their expander’s type: Hyrax (n = 16; 6F, 10M; mean age 8 ± 3 years) or Haas (n = 18; 14F, 4M; mean age 8 ± 2 years). Each patient underwent CBCTs before (T0) and after RPE (T1). Dentoskeletal changes were collected. A paired sample t-test and independent t-test were used to compare each variable within the same group and between groups, respectively, with a 5% significance. The Hyrax group showed an increase in all dentoskeletal parameters; skeletal expansion was significantly increased anteriorly (1.76 mm) and posteriorly (1.93 mm). The greatest dental expansion was observed in the anchorage unit (6.47 mm), about twice as much as permanent molars (3.42 mm). The same statistical significance of Haas group measurements was observed; anteriorly skeletal expansion (2.97 mm) was greater than posteriorly (1.93 mm) and dental expansion was greater on anchored teeth (6.80 mm) than non-anchored teeth (4.57 mm). No statistical significance was observed between Hyrax and Hass groups. CBCT analysis showed that, in RPE, the dental expansion was greater than skeletal expansion. No significant or clinical changes were observed between Hyrax and Haas appliances anchored to primary teeth.

Skeletal Expansion

Maxillary deficiency in the transverse dimension is a common problem in children. The conventional management of such malocclusion is with conventional rapid maxillary expansion. The beneficial effects of such an orthodontic therapy are explained in detail in the literature. But there are also negative effects of conventional rapid maxillary expansion. Thus, the improvements in the methods of expansion has led to discovery of miniscrew assisted rapid palatal expansion. The miniscrew assisted rapid palatal expansion are supported by mini implants and thus enable better skeletal expansion of maxilla. This article will discuss the favourable effects, negative effects, and clinical uses of conventional and miniscrew assisted rapid palatal expansion.

Rapid maxillary expansion (RME) is an orthodontic treatment alternative that aims to increase the transverse direction of the maxilla by separating the median palatine suture (MPS). miniscrew-assisted rapid palatal expansion (MARPE) aims to enhance the orthopedic effects of RME through skeletal anchorage. Thus, the aim of this article is to provide a guide for MARPE planning in cone beam computed tomography (CBCT) and for installation of the expander device with this technique. In addition, a case report of a Caucasian male patient, 16 years and 3 months old with Class II malocclusion, division 1 right subdivision, posterior crossbite of the right side and atresic upper arch in the post-pubertal growth spurt phase will be presented. The patient was treated with MARPE for a period of 5 weeks, when overcorrection of crossbite, correction of maxillary atresia, opening of MPS and creation of a transient diastema between the upper incisors were achieved, evidencing the success of the MARPE technique in a post-pubertal growth spurt patient.
