Passive self-ligating bracket systems (PSLBs), such as the Damon® system (Ormco, US) and SmartClip (3M Unitek®, US) claim advantages over other types of brackets regarding efficiency and effectiveness. However, some studies have questioned their qualities, particularly during the alignment stage, in arch development, and regarding stability of results. This article aims to conduct a scoping review from the past decade’s literature (2013–2023) regarding these assertions about PSLBs. A comprehensive search was performed on several databases. With at least one comparison between PSLBs and the other two bracket types, the inclusion criteria were restricted to English-written randomized controlled trials and split-mouth design studies involving patients receiving orthodontic treatment using PSLB, active self-ligating bracket systems (ASLBs), or conventional/traditional bracket systems (CBs). After screening and manual analysis of the selected studies, only 39 were chosen for the review. ...

Background: A common strategy for the correction of Class II malocclusion is to initially distalize the maxillary molars to create a Class I relationship. Material and Methods: PubMed, Embase, Cochrane Library, Google Scholar, and Clinicaltrials.gov databases were searched to identify and retrieve orthodontic articles that evaluated non-compliance distalization appliances supported by mini-implants up to 11 November 2022. Results: A total of 505 articles were initially identified, and after applying the inclusion criteria, 28 studies were enlisted for evaluation. For the prospective studies, the Risk of bias in non-randomized studies of interventions assessment tool was used, and for the retrospective studies, the Newcastle-Ottawa quality assessment scale. Regarding the palatal devices with mini-implants, the maxillary molars were distalized with a mean value ranging from 2.4 to 5.9 mm, along with a distal tipping ranging between 0.01° and 11°, while when Pendulums were used with mi...
