DEFINITION• INLAY
» Involves occlusal and proximal surface(s) of
a posterior tooth and may cap one or more,
but not all of the cups
• ONLAY
» Involves proximal surface(s) of a posterior
tooth and caps all of the cups

Cavity preparation for cast metal inlays

Inlay - onlay
Higher strenght of a casting alloy is neededSuperior control of contours and contact is desiredWithstand occlusal loads placed on the restorationDistribute occlusal loads over the tooth → decrease the
chance of tooth fractureConserve intact facial and lingual enamel → conducive to
maintaining the health of contiguous soft tissues

INDICATIONS - CONTRAINDICATIONS I.
Higher strenght, superior contours, contact is desired (patient’s wish)Weakened teeth → distribute occlusal loads →
decrease the fractureExtensive proximal caries (subgingival margin)More different restorations and caries → restore
all lesions with one castingRestore root canal filled teethFracture lines

Cavity preparation for class II cast metal inlays
• Convenience form• Outline, retention and resistance forms
– Occlusal step – Enameloplasty– Dovetail retention form– Proximal boxing
• Final cavity preparation– Removal of carious dentin– Preparation of bevels and flares
