PERFORMANCE
What margin design is used for the buccal surface of the crown prep?
modified shoulder (1-1.2 mm)
What margin design is used for the lingual surface of the crown prep?
standard chamfer (0.5-1.0 mm)
What depth should the margins be reduced to?
0.5 mm supragingival (sim-clinic)
What should the first plane be reduced to?
1.5 mm
What should the second plane be reduced to?
1.7 mm
,2|Page
What should the incisal be reduce to?
2.0-2.5 mm
The facial wall of the prep should be ________ to the facial gingival 1/3 of the
tooth's facial surface.
parallel
Why should the facial wall of an anterior prep be parallel to the gingival 1/3 of the
facial surface?
preserve tooth structure and aligns the path of insertion with the natural contour
Why is the lingual wall height of an anterior tooth preparation limited?
Anterior teeth are naturally tapered and shorter lingually; this limits vertical wall
height, reducing inherent resistance form.
How does limited lingual wall height affect resistance form?
, 3|Page
It makes the prep more prone to dislodgment during functional movements
(especially protrusive), so ideal taper is critical.
Why do we have two plains of reduction on the facial surface of crown preps?
Allow for proper material thickness and esthetics
What happens if there is inadequate facial reduction?
thin porcelain (break) and bright spots due to light reflection from opaque
porcelain
Where are margins typically placed for anterior crown preps?
subgingival on the facial surface to promote esthetics appearance
Where do we want to place margins if esthetics are not an issue?
supragingival
