The manufacturing material is an influential biomechanical factor of clear aligners, which encompasses the properties, thickness and the accuracy of fit. Crowded teeth: When teeth in the same row overlap. Byte Highlights. In vitro aligner material testing by three-point bending should consider these geometrical aspects, while keeping the material stresses in a range between 14 and 18 MPa to avoid local microcracks. The flexible SmartTrack material also more precisely conforms to tooth morphology, attachments, and interproximal spaces to. For retainers, we recommend materials ranging from 0. 1 for the new material (Fig. Although placing transfers on t-shirts may seem simple enough, alignment mistakes can be costly. Aligners from these plates – transparent, sufficiently dense and elastic, providing gentle and at the same time constant force on the teeth. Wichelhaus A. 61 µg/mm 3) on average. Within the types of materials that were assessed, not much of a noticeable difference was observed; however, as per the findings obtained through the. Etherealness. 33 mm). The objective of this study was to assess the effects of incisor torque compensation with different thicknesses of clear aligner on the three-dimensional displacement tendency of teeth in cases of extraction. Rapid technological improvements in biomaterials, computer-aided design (CAD) and manufacturing (CAM) have endorsed clear aligner therapy (CAT) as a mainstay of orthodontic. The obtained results show that clear aligners are made up of PETG, semi rigid PU, and a mixture of PU and PETG, with different degrees of crystallinity which affect the transparency of each aligner. The created aligners were classified as aligners with no attachment (NA), aligner with general attachment (GA), and aligner with overhanging attachment (OA). Objectives: To investigate the differences in the mechanical properties of seven different commercial clear aligners, such as surface roughness, elastic modulus, tensile strength and chemical modifications of the materials. The surface of the teeth was used as the base to construct the aligners to mimic the actual thermoforming of an aligner for orthodontic treatment (Figure 2). During clinical practice, several factors can determine an early failure of the attachments in terms of debonding, shape modifications and loss of aligners’ fitting. 8 ± 2. Observe the plastic as it heats. Finally, a 12-year-old patient case is reported to validate the clinical effectiveness of the polymeric clear aligners. Your doctor may provide you with the SureSmile® VPro™ High Frequency Vibration Device to be used only 5 minutes a day with clear aligners.
