ABSTRACT The midpalatal suture has bone margins with thick connective tissue interposed between them, and it does not represent the fusion of maxillary palatal processes only, but also the fusion of palatal processes of the jaws and horizontal osseous laminae of palatal bones. Changing it implies affecting neighboring areas. It has got three segments that should be considered by all clinical analyses, whether therapeutic or experimental: the anterior segment (before the incisive foramen, or intermaxillary segment), the middle segment (from the incisive foramen to the suture transversal to the palatal bone ) and the posterior segment (after the suture transversal to the palatal bone ). Rapid palatal expansion might be recommended for patients at the final pubertal growth stage, in addition to adult patients with maxillary constriction. It represents a treatment solution that can potentially avoid surgical intervention. When performed in association with rapid palatal expanders, it might enhance the skeletal effects of the latter. Of the various designs of expansion appliances, MARPE (miniscrew-assisted rapid palatal expander) has been modified in order to allow its operational advantages and outcomes to become familiar in the clinical practice.

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.

ABSTRACT Objective To investigate the efficacy of microimplant-assisted rapid palatal expansion (MARPE) to treat skeletal maxillary discrepancies during the post-pubertal growth spurt stage. Materials and Methods Sixty patients with skeletal maxillary transverse deficiency during the post-pubertal growth spurt stage were randomly divided into MARPE and Hyrax groups. Thirty patients (mean age: 15.1 ± 1.6 years) were treated using the four-point MARPE appliance; 30 patients (mean age, 14.8 ± 1.5 years) were treated using the Hyrax expander. Cone beam computed tomography scans and dental casts were obtained before and after expansion. The data were analyzed using paired t-tests and independent t-tests. Results The success rates of midpalatal suture separation were 100% and 86.7% for MARPE and Hyrax groups, respectively. Palatal expansion and skeletal to dental ratio at the first molar level were greater in the MARPE group (3.82 mm and 61.4%, respectively) than in the Hyrax group (2.20 mm and 32.3%, respectively) (P < .01). Reductions in buccal alveolar bone height and buccal tipping of the first molars were less in the MARPE group than in the Hyrax group (P < .01). Conclusions MARPE enabled more predictable and greater skeletal expansion, as well as less buccal tipping and alveolar height loss on anchorage teeth. Thus, MARPE is a better alternative for patients with skeletal maxillary deficiency during the post-pubertal growth spurt stage.

Objective: The aim of this study was to evaluate through nasal fiber optic endoscopy and rhinomanometry the patency of upper nasal airways in patients treated with rapid palatal expansion Study design: 30 patients (12 males and 18 females) aged 7–11 years with transverse maxillary constriction underwent rhinomanometric and fiberoptic examination before (T0) and after rapid palatal expansion (T1).The amount of nasopharynx obstruction was quantified with reference to the full choanal surface. Nasal resistance was recorded separately for right and left sides, and combined for both sides. The differences in nasopharynx obstruction and in nasal resistance between T0 and T1 were statistically evaluated. Results: The amount of nasopharynx obstruction significantly decreased after palatal expansion (p<0.001). Total nasal inspiration and expiration resistance significantly decreased at T1 (p<0.001). The reduction ranged between 0. 23 and 0. 66 Pa/cm3/s for inspiration and between 0. 20 and 0,.58 Pa/cm3/s for expiration. A statistically significant positive correlation existed between the T1-T0 differences in the amount of nasopharynx obstruction and the T1-T0 differences in expiration nasal airway resistance (Spearman's correlation coefficient rho = 0.38; p = 0.03). Conclusions: Rapid maxillary expansion has an influence on nasal resistance and improves the patency of upper airways in patients with minor or moderate breathing problems.

Rapid Maxillary expansion or palatal expansion as it is sometimes called, occupies unique niche in dentofacial therapy. Rapid Maxillary expansion (RME) is a skeletal type of expansion that involves the separation of the mid-palatal suture and movement of the maxillary shelves away from each other. RME effects the maxillary complex, palatal vaults, maxillary anterior and posterior teeth, adjacent periodontal structures to bring about an expansion in the maxillary arch. Morphogenesis and anatomical features of the upper jaw determine the choice of the method of rapid palatal expansion with narrowing of the upper dentition, as an effective method for eliminating congenital deformities of the maxillofacial region. The majority of dental transverse measurements changed significantly as a result of RME. The maturity of the maxillofacial structures determines the timing and degree of success of rapid palatal dilatation treatment.

Would midpalatal suture characteristics help to predict the success rate of miniscrew-assisted rapid palatal expansion?

Background: This study is a systematic literature review aiming at identifying the variation of the average nasolabial angle (NLA) in various orthodontic situations. The NLA is one of the key factors to be studied in an orthodontic diagnosis for the aesthetics of the nose and facial profile. Methods: Out of 3118 articles resulting from four search engines (PubMed, Cochrane Library, Turning Research Into Practice (TRIP) and SciELO), the final study allowed the analysis and comparison of only 26 studies. These included studies have considered the NLA in the following cases: teeth extraction, class II malocclusion, class III malocclusion, rapid palatal expansion (RPE), orthognathic surgery, and non-surgical rhinoplasty with a hyaluronic acid filler. Results: The results indicate that teeth extraction and the use of hyaluronic acid fillers significantly affect the NLA. Conclusions: This systematic review shows that a statistically significant change in NLA values occurs in: extractive treatments of all four of the first or second premolars in class I patients; in class II patients with upper maxillary protrusion; in patients with maxillary biprotrusion, except for cases of severe crowding; and in patients undergoing non-surgical rhinoplasty with a hyaluronic acid filler.
