Q
  • Loosen this knob and dial this up to zero to get a zero inclina:on
  • The Bennet angle se=ng (the medial aspect of ____). The right record moves leH condyle into its posi:on.
  • This allows us to program the ar:culator on that side
  • Moving the Bennet angle to 30 degrees opens whole ____ on the ar:culator
A

glenoid fossa

Q

Right Lateral Record Working Side

  • Take the record and place it in. Unlock ar:culator on non working side so its just rota:ng on the ____
  • Its gonna take the non working side, move it down, and sit in there. Then you loosen up the two components and turn them in un:l the ____ touches the condyle of the ar:culator and then you take the bennet angle un:l it touches the ____.
  • Now this is programmed for the pa:ent
  • So the right lateral record on the working side will set the ar:culator on the non working side -Then you lock then leH side and open up the right side and put the leH record in and repeat
A

Adjust Condylar Inclination and Bennett Angle on Non-WorkingSide

  • Now we loosen the second ____, turn condylar inclina:on to loosen black dial
  • Loosen each dial un:l it gently touches, and lock it in
  • Now you have programmed the bennet angle on the non working side

Q

Clinical Significance

—The angle of the ____ is extremely important in clinical dentistry.
—Although we have no control over it, we must not ____ it.
—For example – in a posterior reconstruction (the cusps of the posterior teeth will be changed by prosthetic means) where the angle of the eminentia is not severe, the cuspal form must be shallow or in protrusive movement the maxillary and mandibular cusps will interfere.

A

eminentia

Q

Clinical Significance

—In order to satisfy the criteria for a therapeutic occlusion, it is necessary to eliminate all posterior contacts when the jaw moves into ____.

—The anterior guidance (vertical &horizontal overlap) must be in harmony with the ____ form and the ____ to disarticulate the posterior teeth.

—It may be necessary to reposition the anterior teeth orthodontically in order to reduce the ____ and increase the ____.

—This factor of occlusion can be changed ____, orthodontically or by occlusal adjustment by selective grinding

A 
prostrusive
psoterior cuspal
angle of the eminentia
horizontal overlap
veritcal overlap
restoratively

Q

The Effect of the Curveof Speeon Posterior Cuspal Form

2”radius: The shorter the radius of the antero-posterior curve (Curve of Spee), the ____ the posterior cusps must be.
4”radius: The longer the radius of the Curve, the ____ the posterior cusps maybe.

-Steeper curves have smaller radius -Larger radius will have a ____ curve

A

short
longer
flatter

18
Q

Clinical Significance

—Clinically the dentist has limited control over the radius of the ____.
—Its greatest significance lies in ____ where there are no natural teeth to limit variation in the curve.

A

curve of spee

complete removable prosthesis

19
Q

Tips to keep the dentoform occlusion stable.

—Check each lab session that the dentoform has a solid occlusion with no bounce.
—Amajor change in the occlusion usually requires ____ the screws in the back of the dentoform (ask your instructor for help).
—Don’t work with any teeth missing in the dentoform. —Make sure all the teeth are in correctly and screwed in
solidly.

A

tighten
