What is Association Between Nonextraction Clear Aligner Therapy and Alveolar Bone Dehiscences and Fenestrations in Adults with Mild-to-moderate Crowding about?

## Introduction: This study aimed to assess the association between nonextraction clear aligner therapy (cat) and the presence of alveolar bone dehiscences (abds) and fenestrations (abfs) in adults with mild-to-moderate crowding. ## Methods: Cone-beam computed tomography images from 29 adults were obtained before and immediately after nonextraction cat. total root lengths were evaluated in axial and cross-sectional slices. linear measurement for dehiscence (lm-d) was defined as the distance between the alveolar crest to the cementoenamel junction of each root (critical point set at 2 mm). linear measurement for fenestration (lm-f) was recorded when the defect involved only the apical one-third of a root (critical point set at 2.2 mm). counts of abds/abfs and magnitudes of lm-ds/lm-fs were recorded before and immediately after nonextraction cat at buccal and lingual root surfaces. binary logistic regression analyses and repeated measures analyses of variance were performed. ## Results: Counts of abds/abfs and magnitudes of lm-ds/lm-fs increased at most jaw locations and root surfaces. nonextraction cat was associated with an increased presence of abds and abfs. nonextraction cat was
