Q

Define occlusal interference

A

Undesirable tooth contacts

May produce mandible deviation during closure to ICP

17
Q

Function of a face bow

A

Records terminal hinge axis

Distance between condyles

Relates maxillary teeth to horizontal ref plane enabling cast to be mounted on articulator in an anatomically correct position

18
Q

What is needed to mount mandibular cast (alongside face bow)

A

Interocclusal regi

19
Q

Articulator types

A

Fully adjustable
Semi adjustable - argon
Non adjustable - av value

20
Q

Advantage of a semi adjustable articulator

A

Set Bennet + condylar angles

21
Q

Stages of face bow

A

Mark anterior ref point 43mm above 12
Bite regi using bite fork
Align midline with locating notch
Assemble earbow + transfer jig
Ensure parallel to inter pupillary

22
Q

Ways to get pt into RCP

A

Curl tongue to back of mouth and close

Bimanual manipulation

Chin point guidance w/wo anterior jig
