“…First, the small sample size may preclude drawing of strong conclusions. Moreover, the present study has focused on the first 6 months after the removal of orthodontic appliances as it is a critical period for dental stability, 39 during which the majority of the periodontal fibers reorganize according to the new dental position, despite the supra-crestal fibers taking a longer time. 40 However, dental movement caused by relapse was almost negligible during the 6-month observation period; therefore, the duration of further studies should be extended to at least one year.…”

Objective To evaluate if a remote digital monitoring system added at the end of orthodontic treatment could positively influence the retention phase by reducing the occurrence of misfit of removable appliances, number of emergency appointments (EA), and orthodontic relapse. Methods Twenty-seven patients who completed active orthodontic treatment were divided into the study and control groups. In addition to the standard chairside follow-up appointments at month 1 (T1), month 3 (T2), month 6 (T3), the study group patients were monitored using Dental Monitoring ® with monthly intra-oral scans. Occurrence of misfit of removable retainers, number of EAs, and intercanine width change were recorded for both groups. Differences in EAs and retainer fit were assessed using the chi-square test. Intra-group and inter-group differences in the intercanine width were assessed with Friedman test and Mann–Whitney U test, respectively (α = 0.05). Results The study group showed a significantly lower occurrence of misfit of removable retainers ( p = 0.027) compared to the control group. No significant inter- and intra-group difference was found in the EAs and intercanine width change at each time-point. Conclusions Integrating remote monitoring systems, such as Dental Monitoring ® , to the retention phase of the orthodontic treatment may lower the occurrence of misfit of removable retainers. However, a small sample size and a short observation period limit the strength of this evidence. These preliminary results tentatively suggest that remote monitoring technologies may be beneficial, especially during the COVID-19 pandemic, when the regularity of in-office visits might be disrupted.

“…However, tooth movement can also occur as a result of normal age-related changes. 36 Orthodontic alignment of severely rotated teeth can be inherently unstable 37 and fixed orthodontic retainers can provide adjunctive support. Given the pretreatment rotation of this patient's supernumerary permanent maxillary lateral incisor, a discussion focused on the need for long-term fixed and removable retainer wear was essential.…”

Macrodontia is a relatively uncommon dental anomaly and has often been reported to occur in association with other dental anomalies. Significant orthodontic and restorative challenges may arise in the management of patients with macrodont teeth. This case report demonstrates the opportune and carefully considered management of a patient presenting with both a macrodont and a supernumerary incisor tooth.

Introduction: An innovative retention protocol was developed to create a new 3D‐printed fixed retainer employing SprintRay OnX nanoceramic hybrid resin. The feasibility and usability of the retainer were subsequently evaluated.Methods: Identification and characterization of SprintRay OnX was done using Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy with energy dispersive X‐ray (SEM‐EDX), field emission scanning electron microscope (FE‐SEM), X‐ray diffraction (XRD), and flexural strength. Load–deflection and pull‐out tests were conducted on the 3D‐printed straight wires, with three distinct cross‐sectional geometries: round (1 mm), oval (1 mm × 1.5 mm) and semielliptical (1 mm × 1.5 mm). Twisted G&H and coaxial Respond stainless steel multistrand retainers were used for comparison. In the load–deflection test, a three‐point bending test (3PBT) was employed. For the pull‐out test, the retainer wire was inserted into the composite, which was placed in a centrally located hole of an acrylic block; the retainer wire was subjected to a tensile force along its long axis.Results: Characteristic bands close to those of PMMA were observed in the FTIR spectra. SEM‐EDX and XRD revealed a crystalline material with homogeneously distributed Yb element signals (19.4%). On FE‐SEM micrographs, small clumps were displayed on smooth surfaces. The flexural strength and the flexural modulus were, respectively, 142.48 MPa and 7.842 GPa. All groups of 3D‐printed wires exhibited significantly higher load–deflection levels than the multistrand wires (MSWs). Concerning pull‐out forces, they fell in between twisted G&H (96 N) and coaxial Respond (48.09 N) retainer wires. The 3D‐printed wires fractured cohesively without detachment from the adhesive, suggesting that the chemical bond was adequate for satisfactory wire integration, yet the wire’s strength was compromised. Concerning the cross‐sectional geometry, the load–deflection and the pull‐out forces of 3D‐printed oval and semielliptical wires were significantly higher than that of 3D‐printed round wires, which was attributed to the larger cross‐sections of the wires.Conclusion: Oval and semielliptical 3D‐printed wires offered favorable features as lingual retainers.
