L2. Evaluating Posterior Restorations

When evaluating a restoration, examine from all views:

occlusal/incisal

buccal/facial

lingual/palatal

mesial

distal

The restoration should produce normal physiologic ___ anatomy in harmony with adjacent teeth in the quadrant

occlusal

When checked with articulating paper, all ___ and ___ contacts on the restoration should be consistent in size, shape and intensity with similar contacts on other teeth in that quadrant

centric

exceeding

Hyperocclusion is indicated by ___ markings

bullseye

= heavy occlusion that needs to be shaved down

Hyperocclusion is often also indicated by ___

lack of markings found on adjacent teeth

hitting so hard and early on one tooth that the rest don't get contacted

You need to adjust (via shaving) until ___ markings are visible on adjacent teeth

even

You should try to get some contact on the ___, while avoiding contact at the ___

natural tooth

cavomargin

Replacement teeth in the typodont always need to be ___

equilibrated

Working interference is between ___ and ___

one supporting cusp

one non-supporting cusp

Essentially, in working interference, the ___ supporting cusp makes premature contact with the ___ non-supporting cusp's inner incline

maxillary

mandible

think about sliding the maxilla back until the lingual cusps of the maxilla contact the lingual cusps of the mandible

Nonworking interference between ___

two supporting cusps

The ___ of both supporting, on the maxilla and mandible, cusps contact one another in premature fashion

inner inclines

this is where contact is meant to take place, but it may happen too early for one pair of teeth as compared to others

When nonworking interference occurs, you normally adjust the ___ tooth that is being interfered

maxillary

Protrusive interference is between maxillary ___ and mandibular ___

distal-facing incline

mesial-facing incline

Example: a premature contact on buccal facing incline of the maxillary lingual cusps produces a ___ shift of the mandible

buccal

Example: a premature contact on the lingual facing slope of the maxillary buccal cusp produces a ___ shift of the mandible

lingual

Example: a premature contact on the outer lingual incline of the maxillary lingual cusps produces produces a ___ shift of the mandible

lingual

Isthmus ___ affects required anatomy of the occlusal surface (for proper occlusion)

width

Restorations with a wide B/L dimension require a recessed area for the opposing ___

supporting cusp

Proximal contact needs to be ___

present

not too thin, not too thick... preferably thicker than thinner

Open contacts (can/cannot) close on their own

cannot

Proximal overhangs and excesses can be carved down using a ___ or ___

finishing strip

finishing bur

You can always add more on when using ___ after the original layer sets, but you cannot do this with ___

composite

amalgam

How can you get rid of pits and voids on the surface of restorations?

finishing and polishing

It is very important, as an aesthetically-conscious dentist, to make your restorations ___

shiny!

A ___ can also be used to get rid of excess overhangs, especially in hard-to-reach proximal areas

discoid-cleoid

___ present at the margin indicate that debonding is occuring

Halos

Which bur is good to use when finishing/polishing the occlusal of restorations?

football bur

flexible disc near/at the embrasures

___ often present as what looks like scratches in the composite

Voids

If you have tough to access proximal areas that need to be filled with restorative material, you might need to ___ so as to give yourself better accessibility

prepare an occlusal box
