“…In this regard, there is robust evidence that skeletal control of class III malocclusion in growing subjects can be managed by maxillary protraction with a Delaire facemask, a Petit facemask (with or without preliminary maxillary expansion), an SEC III protocol, or functional appliances [15,[17][18][19][20]. All these appliances represent the gold standard treatment of skeletal class III malocclusion.…”

Background: The aim of the present study was to compare the changes observed in children after the early treatment of mild class III malocclusion using bimaxillary removable plates supported by class III elastics and elastodontic devices. Methods: Twenty children (mean age 7.6 ± 1.1 years) with signs of class III malocclusion were treated using by-maxillary plates (PG group) with class III elastics (10 subjects = mean age 7.9 ± 1.3 years) or using class III elastodontic devices (EG group) (10 subjects = mean age 7.4 ± 0.8 years). Digital models and lateral cephalograms were obtained before treatment (T0) and at the end of treatment (T1). The digital models were analyzed to assess occlusal changes and maxillary morphology using the surface-to-surface matching technique. Changes in cephalometric parameters were also analyzed. The data outcomes were statistically analyzed using the paired Student’s t test for inter-timing assessments and the independent Student’s t test for inter-group assessments. Results: Both groups showed correction of class III malocclusions, with a significant increase in the ANB angle and the overjet (p < 0.05). Subjects in the PG group exhibited a greater reduction in the inter-incisal angle compared to the EG group (p < 0.05). The children in the EG group had a significantly lower percentage of palatal morphology matching between T0 and T1 compared to the PG group (p < 0.05), suggesting greater morphological changes in the palate. Conclusions: Elastodontic appliances (EAs) and bi-maxillary plates successfully correct class III malocclusions in children. However, elastodontic devices significantly improved the morphology of the palate, both in the transverse and anteroposterior directions.

Introduction/Objective. Class III malocclusion is caused by changes in skeletal and/or dentoalveolar structures with typical mesial relationship of posterior teeth. Y? appliance and appliance with screw according to Bertoni can be used in treatment of Class III caused by maxillary retrognathism in period of mixed dentition. The aim of study was to determine and compare changes on skeletal and dentoalveolar structures in patients with Class III treated by ?Y? appliance and appliance with screw according to Bertoni. Methods. 40 patients with Class III were included in this study. Whole sample were divided in two groups, with 20 patients in each group. Including criteria were maxilarry retrognatism, period of mixed dentition and pubertal growth. Excluding criteria were mandibular prognatism, patients with genetical predisposition for skeletal Class III, patients with cleft lip and palate or craniofacial syndrome and period of permanent dentition. Appliances which caused mostly changes on the upper jaw were used in this study because all patients had deficience of maxillary growth. Anamnesis, clinical and functional testing, study casts analysis, analysis of orthopantomograms, lateral cephalograms, extraoral and intraoral photos have been done for each patient. Therapeutic effects were analysed on study casts and lateral cephalograms after this phase of orthodontic treatment. Results. Main dentoalveolar effect was protrusion of the upper incisors. Skeletal effects were not significant. Conclusion. Y appliance and appliance with screw according to Bertoni caused greater changes on dentoalveolar structures comparing to skeletal changes.

The clear aligner, commonly utilized in orthodontic treatment for malocclusion, necessitates the quantification of orthodontic forces, which is highly demanded by doctors for enhancing risk management and treatment efficiency. However, the current technology still faces obstacles in achieving conformal integration of pressure sensors onto clear aligners with large curvature for the quantification and real‐time monitoring of orthodontic forces. In this paper, a conformal iontronic sensing clear aligner (CSA) is proposed based on flexible iontronic sensing mechanism, which conformally integrates the sensor with the aligner to quantify orthodontic forces throughout the treatment process while preserving the aligner's original function. Specifically, the ionic coating is seamlessly integrated onto the diaphragm by applying a layer of ionic paint before molding the clear aligner, while the sensing electrode array, designed using a kirigami‐based structure, is seamlessly adhered to the ionic coating. By integrating the CSA into a dental model, its exceptional sensitivity and precise pressure mapping capabilities have been demonstrated. This enables the identification of various tooth movement patterns, discernment of orthodontic force magnitude, and continuous monitoring of forces throughout the orthodontic treatment. Consequently, this research is expected to significantly advance risk management, outcome prediction, and treatment efficiency in orthodontic treatments.
