What is the purpose of a face bow transfer?

Table of Contents

Facebow transfers are used in prosthetic dentistry to record the anteroposterior and mediolateral spatial positions of the maxillary occlusal cusps in relation to the transverse opening and closing of the patient’s mandible.

How do you do a face bow transfer?

Facebow Step-by-Step

Attach the vertical shaft (numbers right side up) to the earbow and tighten.
Make a mark for the anterior reference point on the patient’s right side of their face 43 mm from the incisal edge of #7 or 8.

Is a facebow necessary?

The findings of this study show that the face bow transfer treatment procedure is not absolutely necessary to mount dental models on an articulator. Students’, professors’, schools’, patients’, and taxpayers’ time and money can be saved by no longer teaching this 133-year-old treatment procedure.

Who invented facebow?

Snow (1835-1923) TIC. 1975 Nov;34(11):9.

What is face bow registration?

Face Bow Registration (gnathological treatment) is a special part of dentistry. First a dental examination takes place, namely the occlusion of the upper and lower jaws, that is, the fitting of the upper and lower teeth against each other in order to determine how the joints and muscles of the jaws are functioning.

What is protrusive movement?

The protrusive movement is in planes parallel to the sagittal plane. The. median sagittal plane is a plane of symmetry of the lower jaw while, for prac- tical reasons, the ocelusal plane is supposed to be horizontal.

What is face bow record?

The facebow recording is the first procedure undertaken when mounting study casts on a dental semi-adjustable articulator. Two reference points are chosen when attaining a facebow record: a posterior one, typically the terminal hinge axis, an imaginary line that runs between the heads of the mandibular condyles.

What is a facebow transfer in dentistry?

What is the purpose of a facebow?

We were taught in dental school that facebow only exists to help us mount the maxillary model on the articulator.

What is a transverse facebow?

This type of facebow transfers the approximate horizontal transverse axis and relies on anatomical averages. Typically, an anatomical landmark such as the external auditory meatus is used to stabilize the facebow and assist in the mounting of the study casts.

How is the data transferred from the facebow to the articulator?

Each manufacturer has their own instrument (s) for transferring the data from their facebow to their articulator. Usually it is a very simple process that involves setting the facebow arms to the articulator, and using a stand to hold up the weight of the maxillary model while mounting stone sets.
