“…Importantly, this literature review only covers articles describing studies using clear aligner on the upper incisors and published from 2010 till the present, since 2009 marked a great innovation regarding optimized features in Invisalign aligner - the introduction of Invisalign Smart Technology. 9 , 10 , 11 Within this period, no randomized clinical trials exist on the topic. This means that no randomized experiments were ever performed on the accuracy and efficiency of tooth movements performed on maxillary incisors since the introduction of optimized aligner features.…”

“…Importantly, only papers published after 2010 were included, since 2009 marked the introduction of Invisalign® Smart Technology, that brought optimized features to the orthodontics community, namely, the SmartTrack material, SmartForce features (including the Invisalign Power Ridge®), and the SmartStage technology. 9 , 10 , 11 The review strategy was lined up according to the Population, Intervention, Comparison, Outcomes, and Study design tool, as presented in Table 1 .…”

The current systematic review appraises the effectiveness of the types of tooth movements performed with Invisalign ® clear aligner on the maxillary incisors. An electronic literature search of published trials was performed through PubMed, LILACS, Scopus, Cochrane Library, and Web of Science databases, and selected journals, from 2009 to 2020. Out of 291 references, five relevant publications were identified for analysis: four studies were performed retrospectively and one prospectively, all non-randomized. Despite the limited set of selected articles, the sample size is significant, with 148 subjects included in the reviewed studies involving the orthodontic treatment of upper incisors. We concluded that movements with the Invisalign ® clear aligner on the upper incisors present distinct accuracy, possibly related with movement complexity; intrusion of the incisors has low accuracy (in some cases, 0% of accuracy was reported when the tooth extruded), while incisor extrusion exhibit some of the highest accuracy values reported in the included studies (45%-142%, when the achieved movement was greater than the predicted). Besides, axial (i.e., torque and tip) and horizontal (i.e., translation and rotation) movements are usually effective, with accuracy values between 39%-156% and 42%-79%, respectively. Overall, we determined that the efficiency of aligner to reach the desired movements in the upper incisors was low, as often refinements were required in the included studies. The use of aligner features must be more often considered to improve movement accuracy.

“…In daily dental practice, especially in the area of orthodontics, there are many common side effects such as pain, discomfort and poor patient cooperation that affect the success of orthodontic treatment with removable appliances [1]. Therefore, with the technological development in oral health care, new ways have been created to promote treatments that are adapted to the needs of patients, thus avoiding these unwanted effects [2]. The term tooth movement using sequential removable appliances was introduced in 1945 by Dr. Harold Dean Kesling [3], who said that "these appliances allow the teeth to be placed in their most ideal position without the need for brackets, bands or wires and that it is also more effective against functional forces".…”

Background: The purpose of this study is to identify the mechanical properties of orthodontic aligners and the effect produced by thermoforming and aging in vitro. Material and Methods: A review of the literature was carried out at the end of 2022 in different search engines (PubMed, Scielo, UNAM), using the search strategy: (aligners), (transparent) and (orthodontics) to identify articles that present information on the mechanical properties and the effect of humidity and temperature on orthodontic aligners. Results: Of a total of 17,130 articles found in search engines, only 21 articles met the inclusion and exclusion criteria. For this systematic review, the most frequent criteria were: aligners, mechanical, and thermoplastic. Conclusions: With the review of the literature carried out, it was concluded that aging due to the effect of water absorption and temperature does not affect the thermomechanical properties and the molecular composition as much as the thermoforming process does.

“…Further, the aligner therapy includes a sequential usage of various transparent trays made from thermoplastic materials ( 6 ). As suitable examples of the latter, polyvinyl chloride, polyurethane (PU), polyethylene terephthalate (PET) and polyethylene terephthalate glycol copolyester (PET-G) can be stated ( 7 ).…”
