Abstract (sommario):

Objective It was hypothesized that, through a repetitive weekly protocol of Alternate Rapid Maxillary Expansions and Constrictions (Alt-RAMEC), the maxilla in cleft patients could be protracted more effectively than with a single course of rapid maxillary expansion (RME). Methods Twenty-six consecutive unilateral cleft lip and palate patients at the age of mixed dentition were included in this prospective clinical study. The rapid maxillary expansion group included the first 16 consecutive patients undergoing 1 week of rapid maxillary expansion (1 mm/day) followed by 5 months, 3 weeks of maxillary protraction. The Alternate Rapid Maxillary Expansions and Constrictions group included the next 10 consecutive patients undergoing 9 weeks of Alternate Rapid Maxillary Expansions and Constrictions followed by 3 months, 3 weeks of maxillary protraction. Daily activation of the weekly expansion or constriction was 1.0 mm. Two-hinged expanders and intraoral maxillary protraction springs were used in both groups. Treatment results were evaluated cephalometrically. Results The amount of maxillary anterior displacement by the 2-hinged expander in the Alternate Rapid Maxillary Expansions and Constrictions group was 3.0 ± 0.9 mm at A point, significantly greater than the 1.6 ± 1.0 mm in the rapid maxillary expansion group. The amount of maxillary advancement with intraoral protraction springs in the Alternate Rapid Maxillary Expansions and Constrictions group was 2.9 ± 1.9 mm at A point, significantly greater than the 0.9 ± 1.1 mm in the rapid maxillary expansion group. The overall amount of maxillary advancement in the Alternate Rapid Maxillary Expansions and Constrictions group was 5.8 ± 2.3 mm at A point. This result remained stable, without significant relapse after 2 years. Conclusions Maxillary protraction using the 2-hinged expander, a repetitive weekly protocol of Alternate Rapid Maxillary Expansions and Constrictions, and intraoral protraction springs is most effective, with stable results at 2-year follow-up.

Abstract (sommario):

Transversal constriction of the maxilla is a common problem and may occur due to many reasons.The maxillary expansion procedures can be classified as rapid maxillary expansion (RME), semi-rapid maxillary expansion (SRME), and slow maxillary expansion (SME). In orthodontic treatment prosodure, it has been evaluated that it causes root resorption especially in the support teeth in many apparatus used for orthodontic treatment and in the expansion apparatus used in the treatment of transverse direction of maxilla. In this review, we aimed to evaluate maxiller expansion protocols and the methods of examining resorption in support teeth. How to cite this article: Topal R, Gündüz Arslan S.

Abstract (sommario):

Maxillary transverse insufficiency usually requires expansion of palate with a combination of orthopedic and orthodontic tooth movements. Four different types of maxillary expansion procedures are used: slow maxillary expansion (SME), rapid maxillary expansion (RME), miniscrew assisted rapid maxillary expansion (MARME), surgically assisted maxillary expansion (SARME). This article aims to review the maxillary expansion by all the rapid maxillary expansion modalities and a brief discussion on commonly used appliances.

Abstract (sommario):

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.

Abstract (sommario):

Maxillary expansion treatments have been used for more than a century to correct maxillary transverse deficiency. Three expansion treatment modalities are used today: rapid maxillary expansion (RME), slow maxillary expansion (SME) and surgically assisted maxillary expansion. Since each treatment modality has advantages and disadvantages, controversy regarding the use of each exists. Rapid Maxillary expansion or palatal expansion as it is sometimes called, occupies unique niche in dentofacial therapy. Rapid Maxillary expansion 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.

Abstract (sommario):

This review was undertaken to compare the effects of surgically assisted rapid palatal expansion (SARPE) and mini-screw assisted rapid palatal expansion (MARPE). Discrepancies in the transverse relation between maxillary and mandibular dentition can result in the development of posterior cross bite. For the correction of posterior cross bite, maxillary expansion is frequently undertaken. The conventional approach for maxillary expansion includes expansion screw being anchored to the maxillary teeth and is known and rapid palatal expansion (RPE) appliance. However, RPE can only be applied in growing individuals and is not as effective in late adolescents and adults. In such patients, surgically assisted rapid palatal expansion (SARPE) technique is used to expand the maxillary arch. As this procedure involves surgery, it deters many patients from choosing SARPE as a treatment option. Recently a non-surgical technique of expansion of maxillary arch has been introduced that can be applied to late adolescents and adults using palatal mini-screws. This technique is known as mini-screw assisted rapid palatal expansion (MARPE). In this review, the studies in the current literature regarding the SARPE and MARPE expansion techniques as compared to conventional RPE were included. It was observed that both SARPE and MARPE are effective methods for achieving maxillary expansion. With both techniques being effective, the advantage of MARPE over SARPE is the non-surgical approach which leads to higher patient acceptance and lower rate of complications.

Abstract (sommario):

ABSTRACT Objective: To test the null hypothesis that there is no difference between the effects of fan-type rapid (FRME) and rapid maxillary expansion (RME) used with an acrylic bonded expansion appliance on dentofacial structures in early occlusal stages. Materials and Methods: This was a prospective clinical trial. The FRME group had an anterior constricted maxillary width with a normal intermolar width, and the RME group had bilateral constricted maxillary width. The FRME group consisted of 20 patients (mean age, 8.96 ± 1.19 years), and the RME group consisted of 22 patients (mean age, 8.69 ± 0.66 years). Lateral and frontal cephalometric radiographs and dental casts were taken before and after expansion and 3 months after completing treatment for each patient. The data were compared using repeated-measures analysis of variance. The paired-samples t-test was used to evaluate treatment and retention effects, and the independent samples t-test was used to consider the differences between the two groups. Results: The maxilla moved downward and forward in both groups. The nasal cavity and maxillary width were expanded more in the RME group, and there were only a few relapses in this group during the retention period. There was significant labial tipping of the upper incisors in the FRME expansion group. The expansion of intercanine width was similar in both groups, but the expansion of intermolar width was significantly greater in the RME group. Conclusion: The null hypothesis was rejected. There was a difference between the effects of FRME and RME used with an acrylic bonded expansion appliance on dentofacial structures in the early occlusal stages.

Abstract (sommario):

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.

AbstractObjective:Phenotypical Down syndrome includes pharyngeal and maxillary hypoplasia and, frequently, constricted maxillary arch with nasal obstruction.Study design:This clinical trial assessed the effects of rapid maxillary expansion on ENT disorders in 24 children with Down syndrome randomly allocated to receive either rapid maxillary expansion or not. Each group received ENT and speech therapy assessments before expansion and after the device had been removed.Results:In the rapid maxillary expansion group, the yearly ENT infection rate was reduced when assessed after device removal (p < 0.01). The parents of rapid maxillary expansion children reported a reduction in respiratory obstruction symptoms. Audiological assessment revealed improvements in the rapid maxillary expansion group (p < 0.01). Cephalometry showed increased maxillary width in the rapid maxillary expansion group.Conclusions:Rapid maxillary expansion resulted in a reduction in hearing loss, yearly rate of ENT infections and parentally assessed symptoms of upper airway obstruction, compared with no treatment. These findings are probably related to expanded oronasal space, due to rapid maxillary expansion.

Abstract (sommario):

ABSTRACT Introduction: Maxillary deficiency, also called transverse deficiency of the maxilla, may be associated with posterior crossbite, as well as with other functional changes, particularly respiratory. In adult patients, because of bone maturation and the midpalatal suture fusion, rapid maxillary expansion has to be combined with a previous surgical procedure to release the areas of resistance of the maxilla. This procedure is known as surgically-assisted rapid maxillary expansion (SARME). Objective: This study discusses the indications, characteristics and effects of SARME, and presents a clinical case of transverse and sagittal skeletal maxillary discrepancy treated using SARME and orthodontic camouflage.

Abstract (sommario):

Background. To evaluate the possible effects of Rapid Maxillary Expansion (RME), such as nasal breathing problems, middle ear function, Obstructive Sleep Apnea (OSA) in the otolaryngology field. RME has already been introduced in orthodontics to expand the maxilla of young patients affected by transversal maxillary constriction. Methods. A literature search was performed using different databases (Medline/PubMed, EMBASE, and CINAHL), from May 2005 to November 2021, according to the PRISMA guidelines. Results. The application of RME in children has shown good results on nasal function, reducing nasal resistances, independently from a previous adenotonsillectomy. These results are not only related to the increasing of nasal transverse diameters and volume, but also to the stiffening of airway muscles, enabling the nasal filtrum function and avoiding mouth opening, thereby decreasing respiratory infections. Positive effects have also been reported for the treatment of conductive hearing loss and of OSA, with the reduction of Apnea Hypopnea Index (AHI), possibly due to (i) an increased pharyngeal dimensions, (ii) a new tongue posture, and (iii) reduced nasal respiratory problems. Conclusions. Otolaryngologists should be aware of the indications and benefits of the RME treatment, considering its possible multiple beneficial effects.

Abstract (sommario):

ABSTRACT OBJECTIVE: The aim of this randomized clinical trial was to evaluate the dental, dentoalveolar, and skeletal changes occurring right after the rapid maxillary expansion (RME) and slow maxillary expansion (SME) treatment using Haas-type expander. METHODS: All subjects performed cone-beam computed tomography (CBCT) before installation of expanders (T1) and right after screw stabilization (T2). Patients who did not follow the research parameters were excluded. The final sample resulted in 21 patients in RME group (mean age of 8.43 years) and 16 patients in SME group (mean age of 8.70 years). Based on the skewness and kurtosis statistics, the variables were judged to be normally distributed and paired t-test and student t-test were performed at significance level of 5%. RESULTS: Intermolar angle changed significantly due to treatment and RME showed greater buccal tipping than SME. RME showed significant changes in other four measurements due to treatment: maxilla moved forward and mandible showed backward rotation and, at transversal level both skeletal and dentoalveolar showed significant changes due to maxillary expansion. SME showed significant dentoalveolar changes due to maxillary expansion. CONCLUSIONS: Only intermolar angle showed significant difference between the two modalities of maxillary expansion with greater buccal tipping for RME. Also, RME produced skeletal maxillary expansion and SME did not. Both maxillary expansion modalities were efficient to promote transversal gain at dentoalveolar level. Sagittal and vertical measurements did not show differences between groups, but RME promoted a forward movement of the maxilla and backward rotation of the mandible.

Abstract (sommario):

A combination of orthopaedic and orthodontic tooth movements are required for expansion of palate to correct maxillary transverse discrepancy. Expansion of the palate can be achieved by three different treatment methods mainly Rapid maxillary expansion, slow maxillary expansion and surgically assisted maxillary expansion. Among the different methods rapid maxillary expansion brings about significant changes in the dental transverse measurements (Agarwal A, Mathur R International journal of clinical pediatric dentistry 2010). This article aims to review the various appliances used for maxillary expansion.

Abstract (sommario):

Some adult cleft palate patients show severe maxillary transverse contraction and posterior crossbite. This case report demonstrates successful surgical-orthodontic treatment of such a patient. Surgically assisted rapid maxillary expansion (SA-RME) was completed prior to comprehensive orthodontic treatment. The osteotomy was performed on both the buccal and lingual aspects of the posterior maxillary alveolus. A Hyrax-type maxillary-expansion appliance was used, and the screw (0.2 mm, one quarter turn) was turned two or three times per day. Comprehensive orthodontic treatment was initiated after extraction of the mandibular first premolars and four third molars. The maxillary lateral incisors were also extracted after active orthodontic treatment. The amount of expansion achieved using SA-RME was greater at the posterior than at the anterior maxilla. Midpalatal suture opening occurred. After orthodontic treatment, occlusal stability was satisfactory. This case demonstrates the effectiveness of SA-RME in adult cleft palate patients with severe posterior crossbite.

Abstract (sommario):

ABSTRACT Objective: The aim of this study was to evaluate the skeletal and dental effects of rapid maxillary expansion (RME) in cleft patients using two types of expanders. Methods: Twenty unilateral cleft lip and palate patients were randomly divided into two groups, according to the type of expander used: (I) modified Hyrax and (II) inverted Mini-Hyrax. A pretreatment cone-beam computed tomographic image (T0) was taken as part of the initial orthodontic records and three months after RME, for bone graft planning (T1). Results: In general, there was no significant difference among groups (p > 0.05). Both showed a significant transverse maxillary expansion (p < 0.05) and no significant forward and/or downward movement of the maxilla (p > 0.05). There was greater dental crown than apical expansion. Maxillary posterior expansion tended to be larger than anterior opening (p < 0.05). Cleft and non-cleft sides were symmetrically expanded and there was no difference in dental tipping between both sides (p > 0.05). Conclusions: The appliances tested are effective in the transverse expansion of the maxilla. However, these appliances should be better indicated to cleft cases also presenting posterior transverse discrepancy, since there was greater expansion in the posterior maxillary region than in the anterior one.

Abstract (sommario):

One of the most common problems faced by an orthodontist while treating young as well as adult patients is the constricted maxillary arch. Expansion of the maxillary arch has been a topic of debate since centuries. The commonly used methods for constricted arch include slow maxillary expansion, rapid maxillary expansion and surgically assisted rapid palatal expansion (SARPE). Slow palatal expansion is a procedure to expand the maxillary arch in transverse dimension to correct the constricted maxillary arch with light forces. The following review article provides detailed information of various slow maxillary expansion appliances with their implications in orthodontics.

Abstract (sommario):

Bonded maxillary expansion appliances have been suggested to control increases in the vertical dimension of the face after rapid maxillary expansion (RME). However, there is still no consensus in the literature about its real skeletal effects. The purpose of this prospective study was to evaluate, longitudinally, the vertical and sagittal cephalometric alterations after RME performed with bonded maxillary expansion appliance. The sample consisted of 26 children, with a mean age of 8.7 years (range: 6.9-10.9 years), with posterior skeletal crossbite and indication for RME. After maxillary expansion, the bonded appliance was used as a fixed retention for 3.4 months, being replaced by a removable retention subsequently. The cephalometric study was performed onto lateral radiographs, taken before treatment was started, and again 6.3 months after removing the bonded appliance. Intra-group comparison was made using paired t test. The results showed that there were no significant sagittal skeletal changes at the end of treatment. There was a small vertical skeletal increase in five of the eleven evaluated cephalometric measures. The maxilla displaced downward, but it did not modify the facial growth patterns or the direction of the mandible growth. Under the specific conditions of this research, it may be concluded that RME with acrylic bonded maxillary expansion appliance did promote signifciant vertical or sagittal cephalometric alterations. The vertical changes found with the use of the bonded appliance were small and probably transitory, similar to those occurred with the use of banded expansion appliances.

We have reviewed our retrospective research about rapid maxillary expansion performed in the early mixed dentition to summarize the results of different studies regarding maxillary dental arch width variation and crowding improvement in light of contemporary literature. The aim is to define the effects of treatments followed until the end of dental arch growth. In all studies, a Haas expander anchored to the deciduous dentition was used. The samples consisted of treated patients with and without a lateral crossbite and homogeneous untreated individuals as controls. Two additional control groups of adolescents and adults in dental Class 1 were also compared. As a result of the analysis, rapid maxillary expansion with anchorage to the deciduous dentition was found to be effective in increasing transverse width in intermolar and intercanine areas, and the change was preserved until the full permanent dentition stage. When performed before maxillary lateral incisors have fully erupted, this procedure allows for a rapid increase in the arch length in the anterior area and consequently, in the space available for permanent incisors with a stable reduction in crowding over time.

Abstract (sommario):

INTRODUCTION: This study evaluated changes in the smile characteristics of patients with maxillary constriction submitted to rapid maxillary expansion (RME). METHODS: The sample consisted of 81 extraoral photographs of maximum smile of 27 patients with mean age of 10 years, before expansion and 3 and 6 months after fixation of the expanding screw. The photographs were analyzed on the software Cef X 2001, with achievement of the following measurements: Transverse smile area, buccal corridors, exposure of maxillary incisors, gingival exposure of maxillary incisors, smile height, upper and lower lip thickness, smile symmetry and smile arch. Statistical analysis was performed by analysis of variance (ANOVA), at a significance level of 5%. RESULTS: RME promoted statistically significant increase in the transverse smile dimension and exposure of maxillary central and lateral incisors; maintenance of right and left side smile symmetry and of the lack of parallelism between the curvature of the maxillary incisal edges and lower lip border. CONCLUSIONS: RME was beneficial for the smile esthetics with the increase of the transverse smile dimension and exposure of maxillary central and lateral incisors.

Abstract (sommario):

Summary Objectives To assess dental root development in two groups of paediatric patients who received treatments with reverse headgear and rapid maxillary expansion and slow maxillary dental arch expansion. Materials and methods The 20 subjects (13 girls, 7 boys; mean age: 8.9 ± 1.3 years) in the first group were treated with a Petit-type reverse headgear attached to a full-coverage bonded rapid maxillary expander via elastics (RME&RHg group). The 20 subjects included in the second group (9 girls, 11 boys; mean age: 9.1 ± 2.2 years) were selected among patients who were treated with Hawley appliances for slow maxillary expansion (SME group). Digitized panoramic radiographs were used. A total of 960 permanent teeth (maxillary–mandibular incisors, canines, premolars, and first molars) were measured quantitatively for pre-treatment and post-treatment. Results No significant increase was found except for the right and left maxillary and mandibular second premolars and left mandibular and first premolar in the RME&RHg group (P < 0.05). Teeth length values increased significantly in all maxillary and mandibular teeth except maxillary first molars and mandibular incisors in the SME group (P < 0.05). Inter-group comparisons showed that statistically significant differences were observed in maxillary and mandibular incisors, left maxillary first premolar, and molar teeth (P > 0.05). Limitation A limitation of this study is the use of two-dimensional radiographic images for root length measurement. However, ethical obligations limit the dental cone beam computed tomography imaging application for protection of paediatric patients from harm. Conclusions RME&RHg therapy inhibits root development of maxillary and mandibular teeth in the early period. However, further studies should be performed to determine whether this effect on root development is reversible or irreversible.

Abstract (sommario):

The aim of the study was to validate a novel digital measurement method to quantify the volume of the midpalatal suture after rapid maxillary expansion (RME). Material and methods: Eight patients with maxillary skeletal transverse deficiency were submitted to palatine suture expansion using the McNamara orthodontic appliance during a period of nine months. After 30 days of treatment, all patients were exposed postoperatively to a cone-beam computed tomography (CBCT) scan. Afterwards, the scans were uploaded into the three-dimensional orthodontic-planning software to allow the volumetric assessment of the palatine suture expansion through palatine rapid maxillary expansion using a McNamara appliance. The repeatability was analyzed by repeating twice the measures by a single operator and reproducibility was analyzed by repeating three times the measures by two operators, and Gage R&R statistical analysis was performed. Results: The expansion of the midpalatal suture by means of the rapid maxillary expansion technique, in terms of digital volume measurement, showed a repeatability value of 0.09% and between the two operators a reproducibility value of 0.00% was shown. Conclusions: The novel measurement technique demonstrated a high repeatability and reproducibility rate for volume assessment of the palatine suture expansion through palatine rapid maxillary expansion technique.

Abstract (sommario):

Background and objectives: The aim of the present paper is to use low-dose computed tomography (CT) to evaluate the changes in the midpalatal suture density in patients treated with rapid maxillary expansion (RME) and slow maxillary expansion (SME). Materials and Methods: Thirty patients (mean age 10.2 ± 1.2 years) were retrospectively selected from the existing sample of a previous study. For each patient, a low-dose computed tomography examination was performed before appliance placement (T0) and at the end of retention (T1), seven months later. Using the collected images, the midpalatal suture density was evaluated in six regions of interest. Results: No significant differences were found between the timepoints in the rapid maxillary expansion group. Three out of six regions of interest showed significant decreases between the timepoints in the slow maxillary expansion group. No significant differences were found in comparisons between the two groups. Conclusions: The midpalatal suture density showed no significant differences when rapid maxillary expansion groups were compared to slow maxillary expansion groups, suggesting that a similar rate of suture reorganization occurs despite different expansion protocols.

Abstract (sommario):

OBJECTIVE: The aim of this retrospective study was to compare the longitudinal stability of two types of posterior crossbite correction: rapid maxillary expansion (RME) and slow maxillary expansion (SME).METHODS: Study casts of 90 adolescent patients were assessed for interdental width changes at three different periods: pretreatment (T1), post-treatment (T2) and at least, five years post-retention (T3). Three groups of 30 patients were established according to the treatment received to correct posterior crossbite: Group A (RME), group B (SME) and group C (control- Edgewise therapy only). After crossbite correction, all patients received fixed edgewise orthodontic appliances. Paired t-tests and one-way ANOVA were used to identify significant intra and intergroup changes, respectively (P < 0.05).RESULTS: Except for intercanine distance, all widths increased in groups A and B from T1 to T2. In the long-term, the amount of relapse was not different for groups A and B, except for 3-3 widths which showed greater decrease in group A. However, the percentage of clinically relapsed cases of posterior crossbite was similar for rapid and slow maxillary expansion.CONCLUSION: Rapid and slow maxillary expansion showed similar stability in the long-term.

Abstract (sommario):

Objective: The aim of this study was to assess the effects of combined headgear used alone or in association with rapid maxillary expansion, as the first step for Class II malocclusion treatment.Methods:The sample comprised 61 patients divided into three groups: Group 1, combined headgear (CH); Group 2, CH + rapid maxillary expansion (CH + RME); and Group 3, control (CG). In Group 1, patients were treated with combined headgear until Class I molar relationship was achieved. In Group 2, the protocol for headgear was the same; however, patients were previously subject to rapid maxillary expansion.Results:Results showed distal displacement of maxillary molars for both experimental groups (p < 0.001), with distal tipping only in Group 1 (CH) (p < 0.001). There was restriction of forward maxillary growth in Group 2 (CH + RME) (p < 0.05) and clockwise rotation of the maxilla in Group 1 (CH) (p < 0.05).Conclusion: Based on the results, it is possible to suggest that treatment with both protocols was efficient; however, results were more significant for Group 2 (CH + RME) with less side effects.

Abstract (sommario):

There has been a long-standing controversy over the efficacy of rapid maxillary expansion to relieve nasal obstruction and improve respiration. Recently rhinomanometry has provided a discipline for the investigation into nasal airway physiology with quantifiable parameters for evaluation and comparable studies. In this trial, a sample of 26 patients (13 male and 13 female, age range 10·10 to 19·6 years), receiving rapid maxillary expansion as part of their orthodontic mechano-therapy, were appraised for nasal airway resistance before and after expansion. The posterior rhinomanometric technique was used, measuring the respiratory flow between pharynx and the nostrils at a preset pressure difference between these two points. The formula for calculating the resistance is derived from the electrical Ohm's Law and requires that the pressure difference be divided by the flow. Reductions were recorded in all cases with an average of 36·2 per cent (range 11·6–58·6). The correlation between the resistance reductions and the delivered expansions (increases in trans-palatal widths) was weak (r = 0·32). In view of the probable significance of the liminal valve in nasal resistance, expansions in this area were assessed by changes in the transalar widths. The correlation between transalar increases and the trans-palatal expansions was weak (r = 0·115), as it was between the transalar increases and the reductions in nasal airway resistance (r = 0·30).
