Crowns and Aligner Attachments: What Holds

What it is

Composite attachments bond to enamel, not to zirconia or emax. The primer, air-abrasion, and pull-strength data that keep attachments on ceramics.

Why it matters clinically

Every treatment decision has a downstream consequence in aesthetics, stability, or cost. The core biomechanics live in clear aligners and tooth movement predictability; the commercial anchors live in treatment cost drivers.

Patient-side reality

Most patients meet this topic mid-consultation. The practical questions are always the same: what will this cost me in time, in money, and in follow-up visits? See ClinCheck planning for how the answers land in the treatment plan.

Evidence base

Numbers here come from peer-reviewed literature (AJO-DO, Angle Orthodontist, JCO), manufacturer multi-centre studies, or clinic audit data. Single-operator series and n<50 studies are flagged in the body, not cited as consensus.

Signals of a good decision

• The clinician can defend the choice in one paragraph without jargon
• The refinement policy is written before treatment starts
• The retention protocol matches the biomechanics of the case
• Cost, time, and compliance expectations are documented in the patient record
