HK 100 EXAM 2 ACTUAL TEST PAPER
QUESTIONS AND SOLUTIONS COMPLETE
REVIEW RESOURCE
●● Role of jaw relation records
Answer: Allow accurate articulator mounting, guide tooth arrangement,
and ensure proper function, esthetics, and stability
●● Vertical Dimension of Occlusion (VDO)
Answer: Distance between two points (nose to chin) when teeth are in
contact
●● Vertical Dimension at Rest (VDR)
Answer: Distance between two points when mandible is at physiologic
rest
●● Freeway space
Answer: Difference between VDR and VDO; normally 2-4 mm
●● Consequences of excessive VDO
Answer: Teeth contact during speech, muscle fatigue, soreness, denture
instability
, ●● Consequences of decreased VDO
Answer: Overclosed face, wrinkles, angular cheilitis, reduced function
●● Centric Relation (CR)
Answer: Maxillomandibular relationship where condyles are in anterior-
superior position independent of tooth contact
●● Clinical importance of CR
Answer: Repeatable, stable reference for mounting and occlusion
●● Record bases
Answer: Temporary denture bases used to support occlusion rims and
simulate final denture base
●● Occlusion rims
Answer: Used to record VDO, CR, lip support, and tooth position
●● Steps to record CR
Answer: Stabilize bases, establish VDO, guide mandible into CR, record
with material, verify repeatability
●● CR verification
