Gold restorationGold restoration

Amalgam vs. CompositeAmalgam vs. Composite

Advantages of AmalgamAdvantages of Amalgam• Ease of placement-tolerates slight

moisture• Good durability• No shrinkage (expansion)• Easy to establish proximal contacts• Low post operative sensitivity

Disadvantages of AmalgamDisadvantages of Amalgam• Poor color match• Expansion• No bond to tooth structure• No early strength

Advantages of compositeAdvantages of composite• Early strength• Beautiful color match• Bonds to tooth structure

Disadvantages to compositeDisadvantages to composite• Very moisture sensitive• Post-operative sensitivity• Leakage in the proximal box• Difficult to establish proximal contact• More steps

Steps we follow in placing a Steps we follow in placing a composite restorationcomposite restoration

– Moisture control-Rubber dam, parotid blockers, assistants

– Complete decay removal-Caries detection dies– Disinfect the preparation-Glumma, hurriseal– Prepare the surface-Self etching primers– Contact closure-bi-tine rings and contoured

matrix bands– Build the box and floor first and cure – Build out the remaining, cure in layers– Shaping -Raptor bur sets.– Checking the occlusion– Polishing-gold knife
