The effects of clinical crown length on the sagittal movement of maxillary central incisor in clear aligner treatment: a finite element exploration.

ABSTRACT:

Background

The mechanism of force application in clear aligner treatment involves wrapping the clinical crowns, suggesting that the size of the clinical crowns may impact tooth movement. The present finite element study aimed to explore the impact of clinical crown length on the sagittal movement of maxillary central incisor in clear aligner treatment.

Methods

The standard maxillary dentition model was developed using computer tomography scanning. Finite element models of the maxillary dentition, alveolar bone, periodontal ligament, and aligners were established. Twelve model groups were divided based on different clinical crown lengths and attachments' position to simulated the tipping and translational movements of the right maxillary central incisor. The dimensions of the
