what is another word for maximum intercuspation?: centric occlusion
What is another word for mandibular movements?: excursive or eccentric movements
In general, which max and mand cusps are supporting cusps?: -max ling
-mand bucc
what is another word for supporting cusp?: centric holding, functional, stamp cusp
In general which max and mand cusps are the guiding cusps?: -max buccal
-mand ling
What is another word for guiding cusps?: non-functional and shear cusps
In the normal alignment of teeth, where are mand teeth positioned in relation to the max teeth?: each mand tooth is positioned both lingual and mesial to its maxillary couterpart
What are the two primary forms of occlusion?: -cusp-to-fossa and cusp to marginal ridge occlusion

-cusp-to-fossa occlusion
In cusp-to-fossa and cusp to marginal ridge occlusion, where does the mand first premolar buccal cusp contact?: the marginal ridges of the maxillary canine and maxillary first premolar
In cusp-to-fossa and cusp to marginal ridge occlusion,where does the mandibular second premolar buccal cusp contact?: the marginal ridges of the maxillary first premolar and the max second premolar
In cusp-to-fossa and cusp to marginal ridge occlusion,where does the mandibular first molar contact?: the marginal ridges of the max second premolar and the max first molar
In cusp-to-fossa and cusp to marginal ridge occlusion,where does the distobuccal cusp of the mandibular first molar contact?: the central fossa of the max first molar
In cusp-to-fossa and cusp to marginal ridge occlusion, where does the mesiobuccal cusp of the mandibular second molar contact?: the marginal ridges of the maxillary first and second molars
In cusp-to-fossa and cusp to marginal ridge occlusion,where does the distobuccal cusp of the mandibular second molar contact?: the central fossa of the maxillary second molar
When drawing cusp-to-fossa and cusp to marginal ridge occlusion, what is the pattern?: -Max, all marginal ridges (except the distal last molar) and two central fossas of molars

-mand,all marginal ridges starting between the premolars and two central fossas of molars
In cusp-to-fossa and cusp to marginal ridge occlusion, a corespondin cusp to marginal ridge pattern occurs except for where?: -the mesiolingual cusp of the maxillary first molar contacts in the central fossa of the mandibular first molar

-the mesiolingual cusp of the maxillary second molar contacts the central fossa of teh mandibular second molar
In cusp-to-fossa,where does the buccal cusp of the mandibular first premolar contact?: the mesial fossa of the maxillary first premolar
In cusp-to-fossa occlusion, where does the buccal cusp of the mandibular second premolar contact?: the mesial fossa of the maxillary second premolar
In cusp-to-fossa occlusion, where does the mesiobuccal cusp of the mandibular first molar contact?: the mesial fossa of the maxillary first molar
In cusp-to-fossa occlusion, where does the distobuccal cusp of the mandibular first molar contact?: the central fossa of the maxillary first molar
In cusp-to-fossa occlusion, where does the mesiobuccal cusp of the mandibular second molar contact?: the mesial fossa of the maxillary second molar
In cusp-to-fossa occlusion, where does the distobuccal cusp of the mandibular second molar contact?: the central fossa of the maxillary second molar
What are border movements?: the maximal extent the mandible can move in any direction
What are functional movements?: normal functions of the mandible
What are the two primary movements that the TMJ is capable of making?: rotation and translation
What is rotation?: hinge movement
What is translation?: sliding movement
If you thrust your jaw forward as far as it will go, what is that called? (A): maximum protrusive
If your teeth are together normally, what is it called? (B): -maximum intercuspation
-maximun intercuspation position
-centric occlusion
If your teeth are end to end, what is it called? (C): -retruded contact position
-centric relation contact
If your jaw is slightly open and pulled back towards your head, what is it called? (C-F): -hinge axis movement
-rotation in centric relation (CR)
If your jaw is open as wide as it will go, what is it called? (D): maximum opening
If your jaw is open normally, what is it called? (E): normal opening and closing
As the mandible moves to the right, what type of position is the rt and lft side of the mandible in?: -rt= laterotrusion
-lft= mediotrusion
As the mandible moves to the right, what type of movement is the rt and lft side of the mandible doing?: rt= laterotrusive movement
lft= mediotrusive movement
What is the laterotrusive side of the mandible known as when chewing?: working side, because when chewing the mandible moves to the side of the food
What is the mediotrusive side of the mandible known as when chewing?: -non-working side
-balancing side
