perikymata (Greek plural of perikyma)
are the pits around the long prisms of tooth enamel. They indicate the places where enamel-producing cells used to make contact with neighboring cells and are the result of normal enamel apposition.

Violations of biologic width
when margins are placed closer than 2 mm to the alveolar bone crest. (
order the following top to bottom

Infringement on the Biologic Width by cutting tooth structure
gingival inflammation -
periodontal pocket formation -
alveolar bone loss
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
- subgingival caries or fracture
- inadequate clinical crown length for retention
- unequal or unaesthetic gingival heights
patient will need surgical intervention
—- —– 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
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.
—- —– 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
