Elastodonzia customizzata in età evolutiva: Studio pilota

Abstract:

OBJECTIVES The introduction of new biocom patible, elastic and resistant inorganic materials in the field of dentistry, has contributed to the birth of a large number of preformed devices, which constitute a specific sector of orthodontics, synthetically defined as elastodontic therapy. The most promising evolution consists in the customization of the devices which, thanks to sophisticated digital set-up technique, introduces the possibility of a three-dimensional orthodontic control of the teeth while maintaining the orthopedic-functional effect. The purpose of the present paper is to verify the therapeutic efficacy and predictability of the results obtained with the use of the new customized elastomer which, thanks to an advanced digital procedure (DDSU: dental digital set up), allows the clinician to pro gram individualized therapies. MATERIALS AND METHODS The research was carried out evaluating a sample of 10 patients, in mixed dentition, aged between 8 and 12 years, all patients were treated at the Department of Biomedical, Surgical and Dental Sciences, Unit of Orthodontics and Pediatric Dentistry, School of Dentistry, University of Milan. All patients included in the study, previously treated with maxillary expansion due to a previous mono or bilateral crossbite, had dental class II sagittal discrepancy and significant increase in overbite and overjet parameters. All subjects underwent scans of the arches and lateral-lateral teleradiography at the beginning (T0) and at the end of the treatment (T1). Vertical and sagittal parameters, both dento-alveolar and skel etal, were measured. Overlaps of 3D models and cephalometric traces were also performed …
