title: Biogeometric guide to groove placement on three-quarter crown preparations.
abstract: An attempt has been made to establish a practical guide to placing the grooves on a three-quarter crown which fulfills biologic, mechanical, and structural requirements. It is our intention to refine and adjust groove placement to biologic and practical limitations in the hopes of ending some of the confusion and difficulty in partial veneer preparations.
