“…The number of activations suggested was almost the same in all designs: in two studies, the screw was turned two times a day, for the first week, then the appliance was activated one time per day; the screw used was a 9 mm Hyrax for the TB group and a 9 mm Jackscrew for the MARPE TTB group [ 23 , 24 ]. In 11 studies suggested activating the screw two times a day until the finish of the expansion: the screws used in these cases were 9 mm Hyrax in the 9 TB group; a Hyrax miniscrew was used in the 1 TB group and 12 mm Hyrax jackscrew in the 1 TB group; one group used the Keles Keyless screw; in the MARPE TTB groups, two studies used 8 mm a miniexpander jackscrew and one study used a 12 mm jackscrew [ 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 ]. Two studies suggested one activation/day with the Hyrax screw [ 36 , 37 ], and the protocol was not determined in one study [ 38 ].…”

Aim: In the literature, many studies and articles are investigating new devices and approaches to achieve rapid palate expansion through the opening of the palatal suture, and evaluating the skeletal, dental, and soft tissue effects. The purpose of this review was to assess how palatal expansion is performed in adolescent patients with permanent dentition. Furthermore, it was reported as an example of successful orthodontic treatment of an 11-year-old female patient affected by maxillary skeletal transverse deficiency, in permanent dentition. Methods: A search of the literature was conducted on PubMed, Cochrane, Scopus, Embase, and Web of Science databases. Inclusion criteria were the year of publication between 2017 and 2022, patients aged 10 to 16 years in permanent dentition, with transversal discrepancy, treated with tooth-borne, bone-borne, hybrid palatal expanders. Results: A total of 619 articles were identified by the electronic search, and finally, a total of 16 papers were included in the qualitative analysis. Conclusions: From this study, it was assessed that MARPE is more predictable, and it determines a more significant expansion of the suture than the Hyrax expander, with fewer side effects.

“…To perform the expansion and to limit unwanted effects more effectively, there exist alternative devices that use the support of miniscrews inserted in the maxilla to improve the distribution of forces [ 28 , 49 ]. These devices can be bone supported, with only bone anchorage, or both bone and dental support [ 29 ].…”

“…21 In recent years, miniscrew-assisted RME appliances have been widely used to achieve a greater skeletal effect. 7 Hur et al 22 reported that mini-screw-assisted RME appliances could be an effective treatment alternative in the management of adults with moderate sleep apnoea by increasing the airway dimension and reducing resistance. In addition, Saloom et al 23 evaluated orthodontic movement in obese and normal-weight patients and reported that obese subjects needed less time to achieve tooth alignment compared with normal-weight patients; however, this difference was not statistically significant.…”

“…In a tooth-borne RME appliance, the supporting teeth may incline toward the buccal and, as a result, periodontal problems may arise. 7,8 Similarly, the skeletal effect is limited in tooth-borne RME appliances. With the advent of mini-screws, mini-screw-assisted RME appliances have been designed to promote enhanced skeletal support and effect.…”

Objectives:The objective of the present study was to compare the dentoskeletal effects of mini-screw-assisted rapid maxillary expansion (RME) in children with different body mass index (BMI) percentiles. Study design:The study was performed on 20 patients who were divided into two groups based on their BMI percentiles as normal-weight (n = 10) and overweight-obese (n = 10). The linear, angular and area analyses were performed on lateral and postero-anterior cephalometric radiographs and three-dimensional dental models before and after RME therapy. Results: A statistically significant increase was observed in maxillary intermolar and intercanine distances and palatal area measurements in both groups (P < 0.05). There was no significant difference between the two groups when dental RME changes were measured on 3D models. A significant difference was observed in latero-nasal and maxillo-mandibular width as well as postero-anterior cephalometric parameters between the groups (P < 0.05). While a significant change was observed in the SN-GoMe, FMA, Z angle, Wits appraisal, total anterior facial height and lower anterior facial height parameters in the normal-weight group (P < 0.05), a statistically significant change was observed in the gonial and nasolabial angles in the overweight-obese group. Conclusions: Mini-screw-assisted RME treatment significantly increased maxillary intermolar and intercanine width, and the palatal area in both groups; however, there was no significant difference between the BMI groups.

“…Unfortunately, exteriorising the force at the level of the definitive molars leads to a distalising vector that is charged to the upper arch and a mesialising one to the lower arch which then leads to the proclination of the lower incisors, more so than with any other functional appliances [19,20]. In recent years, in attempts at reducing the negative effects on Case Reports in Dentistry the patient's teeth, many appliances supported by temporary anchorage devices (TADs) have appeared, especially for those concerning rapid palate expanders [21,22] including appliances to achieve sagittal corrections, such as the Herbst one [23,24]. The latter allows a considerable reduction in the proclination of the lower incisors and attempt to provide the greatest skeletal effect possible.…”

Class II malocclusions are the most frequent within the Italian population. Normally, these malocclusions are caused by a reduction in a mandibular component whose functional stimulus is still very much cause for debate. The negative effect of all types of Class II functional appliances is in the proclination of the lower incisors, which, in subjects whose incisors are already labially inclined, must be checked at all times to avoid serious consequences to these elements. In this case study, a girl aged 14 years and 5 months presented with Class II malocclusion, 2nd division with a convex profile and a visibly retruded chin. The lower incisors presented a marked proclination (−1/Go-Gn ini = 107.7°) in a brachyfacial patient. To avoid further inclination of the lower incisors a Herbst appliance was mounted in two separate sittings. The first part of the appliance including the tubes was mounted to the upper jaw allowing the vestibularisation of the upper incisors in order to increase the overjet. Once this was obtained the lower part of the appliance was mounted together with the telescopic arms associated with two temporary anchorage devices (TADs) in positions 36–37 and 46–47, and an anterior section 33–43 with distal loop to which two double metallic ligatures were anchored at the TADs to contrast the negative effect of the appliance. At the end of the first functional phase, the treatment was refined using MBK fixed therapy to finish the case. The orthodontic therapy led to a visible improvement of the profile and the achievement of a first-class dental–skeletal result on both sides. From the cephalometric evaluation carried out immediately after the Herbst appliance treatment at time T1 and at the end of the orthodontic therapy T2 it was possible to verify a slight increase in the inclination of the lower incisors (−1/Go-Gn fin = 108°). In conclusion, it can be said that the use of the skeletal anchorage avoided, in this case, the proclination effect in the lower incisors due to the use of a Herbst appliance.
