Impact of Dental Occlusion on Attachment Positioning in 3D Aligner Therapy
Abstract
The objective of this study is to analyze cases of attachment debonding during treatment with 3D aligners in patients with reduced interalveolar height. It was established that one of the primary reasons is premature occlusal contact between attachments and antagonist teeth, particularly when they are positioned near the occlusal surface and the teeth are in an anomalous position. Virtual planning does not always accurately reflect real dental contacts without aligners. To address this issue, it is recommended to place attachments more gingivally, positioning them closer to the gingival zone (with a 1.5 mm offset from the gingival margin) to reduce the distance to the tooth’s center of resistance, and to improve both attachment design and aligner materials.
