Restoring lost tooth structure Most common Options: –Gold –Amalgam –Composite

Gold restoration

Amalgam vs. Composite

Advantages of Amalgam Ease of placement-tolerates slight moisture Good durability No shrinkage (expansion) Easy to establish proximal contacts Low post operative sensitivity

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

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

Disadvantages 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 composite 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

Proper isolation

Changing an amalgam for composite

Preparation

Opening the contact

Banding for good contacts

Band in place

Preparing the surface

Dispensing disinfectant

Dispensing self etching primer

Dispensing bond

Applying disinfectant

Disinfectant to preparation, wait 10 seconds then dry

Self etching primer

Self etching primer to preparation, wait 20 seconds then dry vigorously

New brush and bond

Bond to the preparation, lightly dry and cure

Curing light

Curing the bond

Composite, gun, and placement instrument

Small amount to the proximal box

Condensed, less than 1 mm thick and cure 20 seconds

Fill the remainder of the preparation, cure 20 seconds then remove bands with hemostat

Shaping and polishing

Raptor burs to shape the anatomy
