Periodontal health of the gingival tissues is a major concern when planning any fixed prosthodontic treatment. For optimum periodontal health, restoration finish lines should be:supragingival whenever possible (at least 0.5 mm from the free gingival margin) to allow for hygienic cleansingwithin the sulcus at least 1.0 mm and away from the free gingival margin without encroaching on the biologic widthas far as possible subgingivally into the attachment apparatusterminated at the free gingival marginQuestion 6 of 20 7.
