Restoring lost tooth Restoring lost tooth structurestructure
• Most common Options:– Gold– Amalgam– Composite
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
