Arbitrary face-bow is used to transfer the maxillary foundation substitute to semi adjustable articulator.7
Semi adjustable articulator may be "AR CON" and "Non AR CON".
The use of a facebow and a semi adjustable articulator has been recommended conventionally to create a balanced articulation for a successful RCD.3-5,11
Group A (18 patients) had been provided complete dentures using face-bow record to mount maxillary cast on a semi adjustable articulator (Hanau, Waterpik Technologies, Inc.
The adaptation of occlusal plane analyzer to the upper member of the semi adjustable articulator
was done using the Broadrick flag method to create the ideal occlusal plane.
Face bow transfer was made to orient the maxilla to a semi adjustable articulator
and the bite was transferred to the articulator (Fig 3A).
Fully adjustable articulator is indicated for complex full mouth constructions and when alteration in vertical dimension of occlusion is being considered.
The facebow is then attached to the semi adjustable articulator to transfer the recorded relationship of the maxilla by ensuring that the corresponding cast is attached in the proper position relative to the hinge axis of the instrument.
Face bow transfer was done and interoccluasal records were made to mount the casts in centric relation on a semi adjustable articulator
(Hanau Wide view; water pik, Fort Collins, USA) (Figure 3).
The maxillary cast was oriented by means of an arbitrary face bow transfer (Whip mix) on a semi adjustable articulator
(Whip mix 3040) modified for employing Broadrick Flag technique.15, 16
