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.

Summary Background Miniscrew-Assisted Rapid Palatal Expansion (MARPE) is a non-surgical treatment for transverse maxillary deficiency. However, there is limited evidence concerning its efficacy. Objectives This systematic review aims to evaluate the efficacy of MARPE in late adolescents and adults by assessing success rate and skeletal and dental transverse maxillary expansion, as well as treatment duration, dental and periodontal side effects and soft tissue effects. Search methods Seven electronic databases were searched (MEDLINE, Embase, Cochrane Library, Web of Science, Scopus, ProQuest and ClinicalTrials.gov) without limitations in November 2020. Selection criteria Randomized and non-randomized clinical trials and observational studies on patients from the age of 16 onwards with transverse maxillary deficiency who were treated with MARPE and which included any of the predefined outcomes. Data collection and analysis Inclusion eligibility screening, data extraction and risk of bias assessment were performed independently in duplicate. When possible, exploratory meta-analyses of mean differences (MDs) with their 95% confidence intervals (CIs) were conducted, followed by the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) analysis of the evidence quality. Results Eight articles were included: two prospective and six retrospective observational studies. One study had a moderate risk of bias, whereas seven studies had a serious risk of bias. GRADE quality of evidence was very low. MARPE showed a high success rate (mean: 92.5%; 95%CI: 88.7%–96.3%), resulting in a significant skeletal width increase (MD: 2.33 mm; 95%CI: 1.63 mm–3.03 mm) and dental intermolar width increase (MD: 6.55 mm; 95%CI: 5.50 mm–7.59 mm). A significant increase in dental tipping, a decrease in mean buccal bone thickness and buccal alveolar height, as well as nasal soft tissue change was present (P < 0.05). The mean duration of expansion ranged from 20 to 126 days. Limitations One of the main drawbacks was the lack of high-quality prospective studies in the literature. Conclusions and implications MARPE is a treatment modality that is associated with a high success rate in skeletal and dental maxillary expansion. MARPE can induce dental and periodontal side effects and affect peri-oral soft tissues. Given the serious risk of bias of the included studies, careful data interpretation is necessary and future research of higher quality is strongly recommended. Registration PROSPERO (CRD42020176618).

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.

Maxillary transverse deficiency routinely requires expansion of the palate. In prepubertal patients, Rapid Maxillary Expansion (RME) is a reliable treatment modality. However, in skeletally mature patients due to progressively interdigitated mid palatal suture, decreased elasticity of bone and increased stiffness of the osseous articulations of the maxilla with the adjoining bones, palatal expansion becomes challenging. Patients are frequently suggested to opt for more invasive procedures, like the Surgically Assisted Rapid Palatal Expansion (SARPE). The quest for minimally invasive expansion appliances with pure orthopaedic movement led researchers to incorporate mini-implants with conventional RME. Microimplant Assisted Rapid Palatal Expansion (MARPE) maximises skeletal expansion and minimises dentoalveolar undesirable effects and obviates the need for orthognathic surgery. This comprehensive review aims to discuss MARPE as an effective, non surgical, minimally invasive treatment modality for skeletally mature patients with maxillary transverse insufficiency. Furthermore, various designs of MARPE with different placement sites, lengths, and numbers of miniscrews along with the latest technological advancements to improve diagnosis and treatment planning using CBCT and intraoral scan, as well as the use of Computer-Aided Design/Computer-Aided Manufacturing (CAD-CAM) technology to custom fabricate three dimensional (3D) miniscrew insertion surgical guide, 3D laser-printed metallic mini-implant to enhance implant placement accuracy and comfort were discussed along with the clinical significance and limitations of the MARPE. Maxillary Skeletal Expander (MSE) is a unique lineage of MARPE when combined with facemask results in distraction osteogenesis like movement of midface and forms a promising basis for non surgical orthopaedic treatment modality for skeletal class III mature patients. Bone-anchored maxillary expansion appliances provide better vertical control, especially beneficial for hyperdivergent skeletal pattern patients. MARPE significantly increases transverse widths of the nasal floor, nasopharyngeal volume and significantly lowers mean nasal airway resistance thereby facilitating nasal breathing. MARPE results in greater orthopaedic expansion and safety, with fewer undesirable effects and high success rates.

Introduction -Transverse discrepancies of the maxilla are one of the most prevalent skeletal problems. Due to drawbacks of conventional RPE and invasive surgical expansion methods alternative methods were developed such as Mini Implant-supported rapid maxillary expansion (MARPE).Haas17 , Davis and Kronman18, Akkaya et al19 and many other studies have reported the maxillary response after MARPE on the sagittal dimensions, but their results were inconclusive. Aim - This study analyzed the effects on the maxilla in the sagittal dimension after Mini Implant assisted rapid palatal expansion (MARPE) in adolescents using CBCT. Material and method -A pretreatment CBCT image (T1) was taken as a standard initial record for all patients and post treatment CBCT (T2) was taken after three months in retention. The parameters SNA angle, Frankfort horizontal plane to NA angle, A-N perpendicular, ANS –PNS were measured and calculated for evaluation of the sagittal maxillary changes. Comparisons were then made between the two treatment groups (T1, T2). Result -There was a positive increase in both angular and linear measurements from pretreatment to post treatment measurements showing significant skeletal changes in sagittal dimension. Conclusion -The study concludes that there was statistically significant forward displacement of maxilla after transverse skeletal expansion in patients with transverse problems achieved through MARPE in adolescent patients.

Abstract Background: This prospective randomized clinical trial aimed to evaluate the short-term effects of rapid palatal expansion (RPE) and miniscrew-assisted RPE (MARPE) on skeletal, dentoalveolar, and periodontal structures in adolescent and young adult patients. Methods: Thirty-six patients (12 men and 24 women) requiring maxillary expansion were randomly allocated to RPE (n=17) or MARPE (n=19) groups. Upon identical (35 turns) amount of expansion, low-dose cone-beam computed tomography images were taken before treatment (T0), immediately after expansion (T1), and after a 3-month consolidation period (T2). Skeletal, dentoalveolar, and periodontal measurements were performed at each time point. Results: A greater increase in nasal width in the molar region (M-NW) and greater palatine foramen (GPF) was observed immediately after expansion (T1-T0) and consolidation periods (T2-T0) in MARPE group (P<0.05). MARPE and RPE groups showed similar dentoalveolar changes except for the maxillary width (PM-MW, M-MW) (P<0.05). Through the expansion and consolidation periods (T2-T0), lesser buccal displacement of the anchor teeth was observed in the MARPE group (PM-BBPT, PM-PBPT, M-BBPT [mesial and distal roots], and M-PBPT) (P<0.05).Conclusions: Both RPE and MARPE groups exhibited significant triangular basal bone expansion and skeletal relapse during consolidation. Under identical amounts of expansion, the MARPE group showed lower decrease in the skeletal, dentoalveolar and periodontal variables after consolidation. The reinforcement of RPE with miniscrews contributes to the maintenance of the basal bone during consolidation period. This evidence can help clinicians decide the appliance design for maxillary expansion, while preventing periodontal side effects, such as buccal bone dehiscence Trial registration: WHO Institutional Clinical Trials Registry Platform (IRB No. KCT0006871 / Registration Date 27/12/2021)

Objectives. To evaluate the effectiveness of rapid palatal expansion in the treatment of nocturnal enuresis among 6–18-year-old children and adolescents. Methods. Comprehensive searches were carried out in 6 electronic databases (EBSCO, ProQuest, Clinical Key, Science Direct, SCOPUS, and OVID) and supplemented by additional manual searches in 4 orthodontic journals until June 2020. Randomized controlled clinical trials (RCTs) and controlled clinical trials (CCTs) of children and adolescents aged 6–18 years old of both genders who underwent rapid palatal expansion and were considered unresponsive to previous conventional nocturnal enuresis treatment were included in this review. Risk of bias of individual trials was assessed using the Risk of Bias in Non-randomized Studies of Interventions (ROBINS-I) assessment tool for CCTs and the revised Cochrane Risk-of-Bias tool for RCTs (RoB 2). Results. Four studies met all inclusion criteria and were finally included in this systematic review, of which one was an RCT and three were CCTs. Reduction in nocturnal enuresis frequency was reported in all included studies with varying rates and methods of reporting, but most studies reported a statistically significant reduction in the number of wet nights per week. The average range of becoming completely dry 1 year after treatment with an RME was 0%–60%. Also, there was a statistically significant correlation between an improvement in bedwetting and an increase in nasal volume after the use of RME. Conclusion. A rapid palatal expansion device may be considered as an alternative treatment option of the nocturnal enuresis condition with guarded prognosis when other treatment modalities have failed.
