---- ----- on sound tooth structure and retention form, any surgery should provide at least -- mm from the apical extent of the caries or fracture to the bone crest

margin placement on sound tooth structure and retention form, any surgery should provide at least 4 mm from the apical extent of the caries or fracture to the bone crest
