Classification of frequently used attachments in clear aligner therapy based on their configuration and dimensions
| Classification | Configuration | Mesial-distal dimension | Occlusal-gingival dimension | Buccal-lingual dimension |
|---|---|---|---|---|
| Conventional | Elipsoid | 2 mm | 3 mm | 1 |
| Rectangular | 2 mm–5 mm | 2 mm–5 mm | 0.5 mm– 1 mm | |
| Bevelled | 2 mm–5 mm | 2 mm–5 mm | 0.25 mm (bevelled side)1 mm–1.25 (opposite side) | |
| Optimised | Clear aligner provider-determined based on planned tooth movement | Predetermined fixed dimensions by the clear aligner provider | Predetermined fixed dimensions by the clear aligner provider | Predetermined fixed dimensions by the clear aligner provider. |
| Customised | Clinician-designed based on individual tooth movement and treatment needs | Variable depending on the clinician | Variable depending on the clinician | Variable depending on the clinician |
