This conclusion is supported by tooth-reduction experiments showing PLV preparations remove far less coronal structure than crowns—approximately 3% to 30% by weight versus 63% to 72% for all-ceramic or metal-ceramic crowns —and by clinical cohorts reporting high survival in well-controlled veneer protocols, including 97.5% survival up to 7 years, 98% survival over 7–14 years, and 97.4% survival at 10 years for lith…","trust_label":"machine_generated_human_reviewed","editorial_verification":{"status":"human_reviewed","trust_label":"machine_generated_human_reviewed","method":"World ID proof-of-human editorial account","scope":["clinical_integrity","reference_quality","scientific_coherence"],"verification_note":"This Evidence Object is machine-generated and human-reviewed.
