Objectives: To investigate the reliability and accuracy of a monitoring system in patients undergoing orthodontic treatment with a rapid maxillary expander. Specifically, the amount of tooth movement calculated by the software was compared with the actual measurements taken on plaster models obtained during an in-office visit. Materials and Methods: Patients took intraoral video scans using the monitoring software's smartphone application (Dental Monitoring, Paris, France), immediately followed by impressions for plaster models. Intercanine and intermolar width measurements were calculated by the software and compared with those made on the plaster models. Data were analyzed using two one-sided t-tests for equivalence with equivalence bounds of ±0.5 mm. The significance level was set at .05. Results: Thirty sets of measurements were compared. The intercanine and intermolar measurement differences were on average 0.17 mm and −0.02 mm, respectively, and were deemed equivalent. Conclusions: The monitoring software seems to provide an accurate assessment of linear tooth movements.

“…Several authors used the Hass-type of palatal expander to achieve RME in orthodontic patients and evaluated its dentoskeletal effect in the vertical and sagittal dimensions. [12][13][14][15][16] One study conducted by Chester S. Handelman, on the contrary, obtained disparate results. 12 In this study, RME and standard edgewise treatment insignificantly influenced mandibular rotation.…”

Objective: To evaluate the effect of rapid maxillary expansion (RME) on mandibular rotation. Materials and Method: A systematic review of articles selected from 4 electronic databases—PUBMED, Cochrane Central Register of Controlled Trials, Clinical Trials Registry, and Google Scholar—was carried out. Additional studies were hand-searched and retrieved from the reference lists of relevant articles. Studies published till August, 2019, were included in this study. Results: A total of 28 articles were identified through electronic database searching. 16 articles were obtained after elimination of duplicates which were then screened. Full-text articles were assessed according to the eligibility criteria. 2 randomized controlled trials (RCTs) and 14 clinical trials (CTs) were identified for inclusion in the review. These studies effectively highlighted the effect of RME on mandibular rotation, primarily in the clockwise direction. Conclusion: There is a moderate sum of evidence to illustrate the effect of RME on mandibular rotation. It can be concluded that RME brings about clockwise rotation of the mandible, ie in downward and backward directions, thereby increasing the lower anterior facial height. This effect could be attributed to the vertical maxillary movement and the extrusion of the maxillary molars.

“…Some studies recommend activating the device only a few days after the installation of the screws 18 , whereas others recommend waiting 4-6 weeks after installing the screws allowing for a more organized bone matrix around the mini-implants (lamellar structure) 18 . As for the activation of the device, we found different methods in the literature, but the most used seems to be activating the disjunctor twice a day (once in the morning, once in the evening), i.e., an expansion of 0.5 mm/day like a conventional disjunctor 16,23,47,74 . Wilmes recommends activating twice at 90°, i.e., an activation of 0.8 mm/day 18 .…”

Transversal anomalies are very common in clinical practice. In 80% of cases, their interceptive treatment is essential and must be administered as soon as possible to avoid periodontal, joint, or functional problems. It is based on an orthopedic technique aimed at separating the two maxillae above the level of the intermaxillary palatal suture. In 1860 2 , Angell who first described rapid maxillary expansion, which was very quickly discredited; however, since the 1960s it has been most widely used treatment in our arsenal. Conventionally, rapid maxillary expansion is performed in children who are still growing (no suture synostosis; at approximately 12 years), using a disjunctor (described by Biederman) supported by the teeth (two or four rings) and using a median activator twice a day, or 0.5 mm per day. Many studies, including meta-analyses, have

Abstract: MISME can be a better alternative to bonded expansion particularly in patients with vertical growth patterns and lack of anchorage teeth.
