Special Issue Information

Dear Colleagues,

This Special Issue aims to investigate the most recent advances in orthodontic treatment. New technologies and methods recently developed have provided patients with more aesthetic and comfortable options, better analysis and treatment planning. This improvement, mainly driven by 3D technologies and artificial intelligence, in the attempt to make often quicker treatments, also intended to simplify the orthodontist's work without reducing, or even increasing, the efficiency of therapies and their long-term success. All these aspects affect both adult orthodontics and the treatment of growing subjects. Orthodontic retreatments and orthodontic therapies on fragile/vulnerable subjects (pediatric or adult) or requiring an integrated multi-specialist approach (medical/dental) often represent a clinical challenge in which new technologies and new advances can make a difference. Studies that include ethical and medico-legal implications and considerations on the use of new technologies and new advances in the orthodontic field constitute preferential contributions. Scientific contributions in the form of research articles and reviews are welcome. Case reports/series on these topics will be evaluated.

To clarify the mechanics of tooth movement produced by a unique distalizer, Class II Carriere Motion appliance (CMA), in which the maxillary canine is connected to the maxillary first molar with a stiff bar, long-term tooth movement was simulated by the finite element method (FEM). The FEM models of the maxillary canine, premolars, and first molar were made based on a dental study model. The periodontal ligament (PDL) was constructed on the root and assumed to be a nonlinear elastic material. The teeth and the alveolar bone were assumed to be rigid bodies. The tooth moved by accumulating the initial movement produced by the elastic deformation of the PDL. When retraction force was applied to the canine from the mandibular dentition, the canine tipped or rotated clockwise and extruded due to the vertical component of the retraction force. The molar and premolars also tipped and moved distally, but hardly extruded because the vertical force did not act on them. As a result of these tooth movements, the canine protruded from the dentition. An interproximal space was created between the canine and the lateral incisor. These movement patterns were similar to those in other clinical studies using the CMA. Full article

This case report describes the camouflage treatment of a patient with an anterior open bite, bimaxillary skeletal protrusion with a mild class II skeletal pattern, reduced periodontium with generalized slight bone loss, localized severe bone loss at the maxillary upper incisors, and a tongue thrust habit. Orthodontic treatment included modifying the resting posture of the tongue and sectionally intruding maxillary posterior teeth while controlling the extrusion of mandibular posterior teeth using temporary anchorage devices (TADs), followed by sectional mechanics at the maxillary arch and continuous arch mechanics at the mandibular arch, along with interpromximal reduction at the mandibular teeth and inter-arch elastics from the mandibular teeth to the maxillary TADs to minimize orthodontic force magnitude and duration specifically applied to periodontally compromised maxillary incisors. The patient’s chief complaint was addressed, and treatment objectives were achieved, with good esthetic and occlusal outcomes. Stability was shown over a 56-month follow-up period. Full article

This case report describes an 18-year-old female patient with a skeletal class I pattern, mandibular asymmetry, a molar class III on the right side, a molar class II on the left side, and an anterior open bite (AOB). Treatment of AOB is often difficult for orthodontists and a multidisciplinary approach is sometimes required to rehabilitate the correct function and posture of the tongue. In this case the AOB was treated using the Nuvola® OP System: a treatment system that combines orthodontic aligners and a myofunctional elastodontic device called Freedom. An upper molar intrusion with miniscrews was performed during the first phase of the treatment programme, and then the aligner treatment began. The Nuvola® OP System ’s aligners are characterized by lingual pins that guide the tongue to the palatal spot position and take advantage of tongue function. The patient was instructed to wear the Freedom device for 30 min a day and to clench every 3 s with closed lips while wearing the aligners. These exercises improve the fitting of the aligners, improve the tongue’s posture, and take advantage of the masticatory forces to resolve the malocclusion. The patient was successfully treated, thus demonstrating that the Nuvola® OP System is a valid alternative for the treatment of AOB. Full article
