Subgingival restorative dental margins can cause periodontal inflammation and bone loss if placed too far ----.

Subgingival restorative dental margins can cause periodontal inflammation and bone loss if placed too far apically.

2

Violations of biologic width

when margins are placed closer than 2 mm to the alveolar bone crest. (

Consequently, it is recommended that there be at least ---mm between the gingival margin and bone crest to avoid infringement on the Biologic Width

Consequently, it is recommended that there be at least 3.0 mm between the gingival margin and bone crest to avoid infringement on the Biologic Width

9

- subgingival caries or fracture

- inadequate clinical crown length for retention

- unequal or unaesthetic gingival heights

patient will need surgical intervention

10

---- ----- 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

11

Placement of the restorative margin ----- mm into the sulcus allows for the maintenance of the biologic width.

Placement of the restorative margin 0.5 mm into the sulcus allows for the maintenance of the biologic width.
