| Term | Definition |
|---|
| alloy | 2 or more metals |
| amalgam | alloy and mercury combined, used on # 1, 2, and 5 |
| amalgam arm | amalgamator, mortar, pestle, and dappen dish/amalgam well |
| amalgam ratio | 1:1 alloy and mercury |
| amalgam setup | 24 hours |
| amalgam return | 2 days to polish restoration |
| retention pins | reinforce amalgam restoration because of inadequate edge strength |
| amalgam polishing arm | tin oxide and right angle attachment ? |
| mercury | can NEVER be handled and stored in water or fixing solution |
| mortar | capsule to mix amalgam |
| pestle | ball to break up pellet of alloy |
| composite types | macrofilled (large particles), microfilled (small), hybrid (macro and micro) posterior and anterior |
| composite curing | self cure- 2 paste (base and catalyst), and light cure |
| acid etch | a phosphoric solution, for chemical retention, 1 minute, white and chalky |
| composite advantages | matches tooth color, less tooth removed, placed on any tooth, less marginal leakage |
| composite disadvantages | acid etch is hazardous, can discolor over time, weaker in posterior |
| varnish | cannot use under composite, will not set up |
| composite arm | rubber dam, composite placement instrument |
| finishing strip | smooth interproximal anatomy |
| composite | used on restorations # 3, 4, 5 |
| cast crown types | (5) full gold, porcelain fused to metal, 3/4 crown, onlay, inlay |
| cast crown | 2 visits, prep and cementation |
| chemical retraction | string impregnated with an hemostatic to help with oozing. (most popular) |
| mechanical retention | temporary crown placed for a couple of days to displace gingiva |
| cast crown arm | 1st visit- alginate impression material |
| amalgam advantages | easy insert to cavity prep, limited change, limited leakage, withstands corrosion, good strength |
| amalgam disadvantages | does not match tooth color, will tarnish, inadequate edge strength, thermal conductivity, needs mechanical retention (dovetail) |
