Description
Yuanyou Lin and five co-authors measure aligner accuracy for back teeth in a 2025 study. Clear aligners struggle to slide molars forward bodily without tipping them. Extraction cases with moderate anchorage needs expose that weakness. Thirty two patients treated after premolar removal formed the sample.
Digital models before and after treatment were overlaid in three dimensions. Planned and achieved movements were compared tooth by tooth. Upper first molars moved forward more than planned and tipped notably. Lower molars moved less but still tipped. Attachment designs on the teeth changed the outcome measurably. The double attachment option performed best among those compared. The numbers give orthodontists realistic expectations for aligner anchorage. Case selection can lean on the tipping data.
