Open AccessThe effect of enhanced structure in the posterior segment of clear aligners during anterior retraction: a three-dimensional finite element and experimental model analysis
Mesial tip** of posterior teeth occurs frequently during space closure with clear aligners (CAs). In this study, we proposed a new modification of CA by localized thickening of the aligner to form the enhanc...

Open AccessStress and movement trend of lower incisors with different IMPA intruded by clear aligner: a three-dimensional finite element analysis
During the intrusion of lower incisors with clear aligners (CAs), root disengagement from the alveolar bone often occurs, resulting in serious complications. This study aimed to determine the potential force m...

Open AccessEffects of the advanced mandibular spring on mandibular retrognathia treatment: a three-dimensional finite element study
The Advanced Mandibular Spring (AMS) was newly developed as a dentofacial orthopedic appliance in conjunctive use of clear aligners to treat Class II malocclusion with mandibular retrognathia in adolescents. T...
