Study Notes
Dental Restorative Materials
- Used for filling cavities, covering discoloration, and correcting tooth alignment.
- Direct restorative materials are applied in a single office visit.
Composite Fillings
- Composed of plastic resin and powdered glass filler.
- Types include bulk-fill (up to 5 mm thickness), conventional (2 mm thickness), flowable, and packable.
- Flowable composites have low filler content, while packable composites have high filler content.
- Less polymerization shrinkage is observed in bulk-fill compared to conventional composites.
Etching and Bonding
- Etching involves phosphoric acid (34%-37%) to create micromechanical retention.
- Bonding process requires etching and priming to achieve a durable bond with composite.
- Adhesive generations vary from 3-step (etch, prime, adhesive) to 1-step systems that combine etch, prime, and adhesive.
Light Cure Machine
- Cures composite increments and bonding agents with a blue light.
- Curing times vary: composite (10-40 seconds) and bonding (10-20 seconds).
Amalgam Restorations
- Silver-colored restoration used predominantly in posterior teeth.
- Mixture contains mercury, separator, and silver alloys (copper/tin/silver).
- Retained in cavities through mechanical retention after proper cavity preparation.
Steps for Amalgam Restoration Placement
- Prepare the cavity with undercuts for retention.
- Apply dentin desensitizer, air dry after 30 seconds.
- Mix amalgam in an amalgamator for 6-8 seconds, then transport to the cavity.
- Fill cavity incrementally, condensing with a condenser.
- Use a burnisher to smooth and carve the anatomy of the restoration.
Indirect Restorations
- Created outside the mouth, then placed onto the affected tooth.
- Examples include crowns, bridges, dental implants, inlays, onlays, and veneers.
Fixed Prosthesis
- Types include PFM (porcelain fused to metal), full ceramic crowns, and full metal crowns.
Removable Partial Dentures
- Made from acrylic or chrome cobalt materials.
- Acrylic complete removable dentures are another option.
Process for Metal Framework of Removable Denture
- Design drawn, followed by wax frame creation.
- Wax is melted and replaced with metal to form the denture framework.
