15. Second Prosthetic Appointment
• Prior to appointment a screw-retained baseplate and wax rim are fabricated
• Vertical Dimension of Occlusion (VDO) and Vertical Dimension of Rest (VDR) are
evaluated and verified
• Bite registration is taken
• Articulator mounting procedures (Facebow transfer / Stickbite)
• An alternative technique is to use a bite registration and the “Teeth-In-A-Day”
prosthesis to mount the the new master model on the articulator in the dental office
(only if the VDO from transition prosthesis is to remain unchanged)
