Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Patients receiving either clear aligner treatments were enrolled in this study. During the same time period, patients receiving fixed orthodontic treatments well-matched with clear-aligner patients by similar ages (difference \< 3 years), same gender and similar levels of severity of malocclusion \[similar Index of Complexity Outcome and Need (ICON) level\] were enrolled.The two groups were well-matched with ages, gender and levels of malocclusion severity. Pain perception, anxiety and quality of life were assessed through visual analogue scale (VAS), state-trait anxiety inventory (STAI) and oral health impact profile-14 (OHIP-14), respectively.
