General Considerations

Question 1

Centric Relation

Answer 1

• The maxillomandibular relationship in which the condyles articulate with the thinnest avascular portion of articulor disk
• Condyle-disc complex in the anterior superior position against articulor eminence
• Terminal hinge position
• Only rotational

Question 2

Maximal Intercuspal position or Centric Occlusion

Answer 2

• the complete intercuspation of the opposing teeth independent of condylar position
• in 90% of people CR and MI do not coincide
• Bimanual manipulation to recreate

Question 3

Interocclusal Record Material and mounted with

Answer 3

• Wax (aluwax) mount with irreversible hydrocolloid (alginate)
• Elastomeric material ( PVS, Polyether) mount with elastomeric registration or zinc oxide eugenol paster

Question 4

Disclusion includes 4

Answer 4

• Condylar guidance
• Incisal guidance
• Canine Guidance
• ANterior guidance

Question 5

Condylar Guidance

Movement

Determined by

Represented on articulator

Determinat of

Answer 5

• Protrusion
• Slope of articular eminence
• Reprsented by Horizontal Condylar Inclination on articulator
• Posterior determinant of occlusion

Question 6

Incisal Guidance

Movement

Articulator represented by

Determinant of

Answer 6

• Protrusion
• Incisal of lower I on Ling of upper I
• Represented by pin and guide table
• ANterior determinant of occlusion

Question 7

Canine Guidance

Movement

Contact occurs with

Answer 7

• In lateral movement all posterior teeth disclude
• Contact occurs only with canines on working side

Question 8

Anterior Guidance

Consists of

Protrusive

Lateral

Answer 8

• Both Incisal guidance and canine guidance
• During protrusive
  
  • Incisal and condylar guidance provide clearance for all posterior teeth
• During lateral, canine on WORKING side and condyle on Balancing side provide clearance for posterior teeth on balancing side
