Face-Bow Transfer Record

What setting should the bennett angle and condylar guidance angle be set to on the articulator?

Bennett: 15. Condylar guidance: 30.

bite fork registration is captured using ____________.

Blu-mousse.

When face-bow record is transferred to the articulator, maxillary cast is mounted on the upper member of the articulator establishing the ______________ plane.

axis-orbital plane.

What are the advantages of using a face-bow transfer?

--More accurate representation of patient functional components. --Better esthetics. --Less adjustment of indirect restorations. --Better restorations overall.

Where should the operator be positioned when capturing the bite fork registration?

--stand behind patient. --align center mark of bite fork with the midline.

What should the incisal guide pin be set to?

0.

What are the 3 reference points captured on a face-bow transfer?

2 posteriors: hinge axis of the condyles --Recorded in the patient's external auditory canal with the earpieces on the face-bow. --Represents the rotation (hinge) axis of each condyles. 1 anterior: Nasion or orbital point. --Determined by a specific distance from the nasal bridge by the nasion relator.

What is a face-bow transfer?

Designed to enable the user to quickly and easily mount casts of a patient's dentition on an articulator that will reproduce their natural relationship and movements with acceptable degree of accuracy.

_______________ is the imaginary line connecting the two centers of rotation in each mandibular condyle.

Hinge axis.

T/F: the dentoform is usually considered to have CR/MS in harmony with ICP/MI.

True.

A _____________ is used to mount maxillary casts precisely on the articulator reproducing the 3D position of the maxilla and to establish the relationship of the maxillary teeth to certain anatomic reference points.

face-bow transfer.

the relationship of the maxilla to the mandible is represented by the __________ axis.

hinge axis.

What method is used to mount the maxillary cast (direct or indirect)?

indirect.

______________ is the distance between the rotational centers of the two condyles.

intercondylar distance.

Once the lower cast is mounted, the distance between the hinge axis and the lower teeth is established. A _______________ can be established for each tooth representing tooth contacts in closure.

mandibular closing arc.

What marks should be caputured in a bite fork registration?

maxillary cusp tips and incisal edges.

the bite fork should be parallel to _____________ when capturing bite fork registrations and face-bow transfer records.

parallel with the pupil line or to the floor.
