Objective: Considering the success of infrazygomatic mini-implants in conjunction with traditional braces, this study aimed to evaluate the efficacy of infrazygomatic mini-implants in en masse maxillary distalization utilizing clear aligner therapy. Methods: In a three-dimensional finite element study, we evaluated the en masse maxillary dental distalization through the use of infrazygomatic mini-implants equipped with varying force-application arm lengths (0 mm, 4 mm, and 8 mm). Vertical, sagittal, and horizontal displacements were quantified. Results: Intrusion was observed in the incisors at all force application arm lengths (0 mm, 4 mm, and 8 mm), with similar sagittal displacement tendencies and labial crown tipping. Among all maxillary teeth, only the canine exhibited distalization of both the crown and root. Distalization of the posterior teeth was achieved, with the greatest magnitude of distalization occurring at the 0-mm force application arm length, which was characterized by minimal tipping and reduced vertical movements compared to the other force application arm lengths. Conclusions The findings indicate that infrazygomatic mini-implants represent a viable approach for facilitating targeted tooth movement in clear aligners across various force-application arm lengths. These results may inform orthodontic treatment strategies in non-extraction cases.

Objective: This study aimed to assess the effects of commonly consumed hot drinks on the force decay of orthodontic elastomeric chains. Methods: This in vitro experimental study evaluated 375 pieces of elastomeric chains with six rings placed on a jig. Four rings were stretched by 23.5 mm corresponding to the approximate distance between the canine and the second premolar.Fifteen pieces served as reference samples at time zero, and 360 pieces were randomized into four groups: control, hot water, hot tea, and hot coffee. Each group was further divided into six subgroups (n = 15) according to the different exposure periods. The specimens in the experimental groups were exposed to the respective solutions at 65.5°C four times per day for 90 seconds at 5-second intervals. The control group was exposed to artificial saliva at 37°C. The force decay of the samples was measured at 1, 2, 7, 14, 21, and 28 days using a universal testing machine. Data were analyzed using repeated-measures analysis of variance. Results: Maximum force decay occurred on day 1 in all groups. The minimum force was recorded in the control group, followed by the tea, coffee, and hot water groups on day 1. At the other time points, the minimum force was observed in the tea group, followed by the control, coffee, and hot water groups. Conclusions Patients can consume hot drinks without concern about any adverse effect on force decay of the orthodontic elastomeric chains.
