Lingual contour of the mandibular denture should be ______ and there should be a slight ________ to prevent tongue biting and to anchor the denture teeth within the acrylic resin.

A

CONCAVE….gingival roll

32
Q

_________ of the buccal and lingual flanges can help hold the denture in place. These flanges define the boundaries of the “______ zone” where the force from the ______ equals the forces from the ______ and lips respectively.

37
Q

When do we do a LAB remount?

A

AFTER processing

38
Q

WHY do we do a LAB remount after processing the denture? (3)

A
  1. to get VDO back after processing 2.Get CR back 3.restore bilateral occlusion
39
Q

LAB remount-make sure your pin is set back at ____.

A

zero!

40
Q

Fixing occlusion errors after processing/LAB remount: Premature contacts, holding remaining teeth out of occlusion….

A

Deepen the FOSSAE..DO NOT shorten cusps

41
Q

Fixing occlusion errors after processing/LAB remount: Cusp tips are TIP-TIP….

A

Move upper cusp inclines buccally. Move lower cusp inclines Lingually..(the cusps are narrowed)….DO NOT SHORTEN CUSPS

42
Q

Fixing occlusion errors after processing/LAB remount: Upper teeth too Buccal in relation to the lower…

A

broaden the central fossae-Buccal cusps of lower are moved buccally…DO NOT SHORTEN CUSPS

43
Q

What are the 3 places on the tooth that are OK to adjust in the LAB remount (post processing)? What do you AVOID?

A

OK—1.Cusp inclines 2.Central fosse 3.Marginal ridges…..AVOID 1.functional cusp tips-unless ABSOLUTELY required

44
Q

What do you do after equilibrating in MIP?

A

Equilibrate in eccentric movements (working, balancing, protrusive)

45
Q

Most occlusal discrepancies found during 􏰀working􏰁 and 􏰀balancing􏰁 can be corrected by reducing premature contacts on the ______ cusps of the maxillary teeth and the _______ cusps of the mandibular posterior teeth (non- centric holding cusps) otherwise known as the ____ rule

A

buccal of max…lingual of mand…BULL

46
Q

Equilibration in working- Check the contacts on the buccal inclines of the upper buccal cusps. During working, they should all be about _____. If not, make the appropriate adjustments

A

equal

47
Q

Slide the articulator through working again and observe the contacts on the balancing side, the lingual inclines of the lower buccal cusps. Premature balancing side contacts are reduced by grinding on the ______ inclines of the lower ______ cusps. If there are no balancing side contacts, the _______ side contacts should be reduced until balancing side contacts appear.

A

lingual inclines of lower buccal cusps….working

48
Q

Equilibrate in protrusive. This may require grinding of the anterior teeth on the ______ of the maxillary and selective reduction of the ______ inclines of the posterior teeth.

A

lingual of the anterior…buccal

49
