EPA 4C: Dentate Indirect Crown

Dentate Indirect Crown	Meets Expectations of the Graduate	Progressing	Below Expectations	Critical Error

Isolation and Tissue Management	No damage and/or optimal isolation		Poor isolation and/or tissue damage requiring finishing/polishing	Poor isolation and/or tissue damage that requires a major recontour or restoration
Preparation
External Outline	Margin location ideal (0.5mm above the FGM) Margins regular in form No iatrogenic damage	Margin location slightly over- or under- extended (±0.5mm) Margins slightly irregular	Margin location decidedly over- or underextended (> 0.5mm, < 1mm) Margins decidedly irregular and recognized Minor damage to adjacent tooth (recounter) and/or soft tissues	Margin location grossly over or under extended (> 1mm) Margin decidedly irregular and not recognized Severe damage to adjacent tooth (restore) and/or soft tissue
Internal Outline	Preparation extends into tooth as necessary for the chosen restorative material	These areas are slightly over- or under- reduced (± 0.5mm) Occlusal - Axial Walls - Cusp Bevel	These areas are decidedly over-(0.5-0.8mm) or under- reduced Occlusal - Axial Walls - Cusp Bevel	These areas are grossly over-(>0.8mm) or under- reduced Occlusal - Axial Walls - Cusp Bevel
Taper	Taper ideal (5–10° TOC)	Taper slightly excessive (10–15° TOC)	Taper inadequate < 5° Taper decidedly excessive (15–20° TOC) Minor undercuts	Gross undercuts (margin less than 0.5mm after blackout)
Finish of Walls and Margins, Definition	Walls and margins smooth Smooth/planar occlusal anatomy Chamfer width and form ideal	Preparation slightly rough Chamfer not ideal, but acceptable	Preparation decidedly rough or ill-defined and recognized Chamfer ill-defined or nonfunctional and recognized Debris remaining on the preparation	Preparation decidedly rough or ill-defined and not recognized Margin ill-defined or nonfunctional Lip or J margin
Adjacent Tissues	No iatrogenic damage		Damage to adjacent tooth or soft tissue - Recontour	Damage to adjacent tooth or soft tissue - Restore
Restoration
Surface	Surface uniformly smooth, replicates normal textures	Surface slightly rough, pitted, or lacking finish	Surface decidedly rough or pitted	Deeply pitted or grooved
Marginal Integrity	Margin is smooth Margin is not short, long, or open	Margins are slightly: Detectable with explorer Over-extended Under-extended	Margins are slightly: Detectable with explorer Over-extended Under-extended	Margin open Gross over-finish Gross over-extension
Occlusal Anatomy and Functions	Cusp planes, grooves and marginal ridges continuous with existing tooth form Occlusion restored	Slightly over/under contoured Canine guidance not maintained Anatomy lacks definition	Premature occlusal contacts Balancing or non-functional contacts exist Decidedly over contoured, excessive depth of anatomy Anatomy absent	Restoration fractured, missing Gross hyperocclusion, no other teeth in contact Occlusal contact not existent
Axial Contour and Proximal Contact	Axial contours continuous with existing tooth form Proximal embrasures and contact restored	Slightly over- or under- contoured Proximal contact visually closed, lacks intensity	Decidedly over-or under-contoured, outside normal physiologic/anatomic range Soft tissue impingement	Grossly over- or under-contoured Proximal contact visually open
Adjacent Tissues		Common path of draw exists		Common path of draw does not exist without modifying one or both preparations
