I think it is Rt mesiotrusive correct me if i m wrong.
ASDA I-L means which year, If u hav softcopy, can u send it to me pls..?
my id is [email protected]
Thanks in advance.

ans is given as left mesiotrusive.can anyone pls explain that.....thanku.

 

[Be positive]

ans is given as left mesiotrusive.can anyone pls explain that.....thanku.

Hi pbkal
do u hav soft copy of asda I-L?
I hav some papers without answer key thats why i m asking u asda I- L came in which year?
can anyone plz.......
Thanks

ans is given as left mesiotrusive.can anyone pls explain that.....thanku.

Though i am not that good at explaining but still i am trying to expalin for this in the way i can..
On the non-working side inner inclines of supporting cusps can cause any interfering contacts (if any ). so left mesiotrusive movemnet can likely be the cause of breakage of lingual cusp (suporting cusp) of tooth #5 as the mandible moves to working side from non working side(right side ) .
I hope this makes sense.
Plz correct if wrong

 

[gytbdc]

q. All the teeth have 4 point angle this is true or false?

Q.A working interference is a premature contact of posterior teeth on the same side as the direction of the mand movement
A protrussive interference is a premature contact b/w the mesial aspects of maxillary posterior teeth and the distal aspects of mandibular post.teeth
a.both statement is true
b.both statement are false
c.first statement is true ;second false
d.first false ;second true

plz somebody also explain these movement I m unable to undderstand these movements.thanks in advance

 

[gytbdc]

can any one tell me about functional outer aspect.[FOA]

 

[HOPE2DDS]

q. All the teeth have 4 point angle this is true or false?

True.

 

[HOPE2DDS]

can any one tell me about functional outer aspect.[FOA]

Check kaplan review for this . They have nicely explained it over there.

 

[Be positive]

can any one tell me about functional outer aspect.[FOA]

FOA -The outside 1-2 mm of the supporting cusps which means
buccal surface of the man buccal cusps and lingual surface of the max
lingual cusps.

q. All the teeth have 4 point angle this is true or false?

True.

thank you HOPE2DDS,Be positive
can u explain l can understan about postteeth i.e mesio-facio-occlusal ,dis-fac-occ,mesio-ling-occ,dis-lin-occl.but in ant teeth there is incisal edge so how 4 point angle .
however ans given true

U can also divide the incisal edge into 4 borders ie labial,mesial,lingual and distal.And the 5th one is incisal surfaces.so now i hope u got it...

here another q
which of the following is the most reproducible mandibular position?
a.centric occlusion
b.functional occlusion
c.postural position
d.centric relation
plz ans with reason

 

[gytbdc]

q.The occlusal surface ofthe primary max 1st molar is
1.rhomboidal
2.rectangular

 

[gytbdc]

The nonworking pathway of the mesial cusps on mandibular post teeth is in which direction?
1. distofacial
2. distolingual
3. mesiofacial
4.mesiolingual

what will occur if working pathway ?

I really don't able to understand these types of questions.plz somebody help.

 

[iomega]

what is the diffrence between occlusal table & occlusal surface?

 

[iomega]

The nonworking pathway of the mesial cusps on mandibular post teeth is in which direction?
1. distofacial
2. distolingual
3. mesiofacial
4.mesiolingual

what will occur if working pathway ?

I really don't able to understand these types of questions.plz somebody help.

i think for the 1st one its mesiolingula direction..(since on non-working side the mandible moves forward, downwards n mesially)
n for working side it'll b mesiofacial.
correct me if i'm wrong.

here another q
which of the following is the most reproducible mandibular position?
a.centric occlusion
b.functional occlusion
c.postural position
d.centric relation
plz ans with reason

i think the ans is centric relation..

 

[iomega]

q.The occlusal surface ofthe primary max 1st molar is
1.rhomboidal
2.rectangular

i think its rhomboidal.

 

[Truth seeker]

i think the ans is centric relation..

centric relation for sure is most reproducible, thats how the definition goes .

 

[Truth seeker]

what is the diffrence between occlusal table & occlusal surface?

occlusal table : masticating surfaces on the occlusal surface
occlusal surface : includes occlusal table + outer inclines of the cusps , more appropriately the entire occlusal area

 

[Truth seeker]

The nonworking pathway of the mesial cusps on mandibular post teeth is in which direction?
1. distofacial
2. distolingual
3. mesiofacial
4.mesiolingual

I really don't able to understand these types of questions.plz somebody help.

whats the key to this question ? is the question in the paper worded exactly same way ?

 

[iomega]

occlusal table : masticating surfaces on the occlusal surface
occlusal surface : includes occlusal table + outer inclines of the cusps , more appropriately the entire occlusal area

thanx truth seeker...

 

[gytbdc]

n for working side it'll b mesiofacial.
correct me if i'm wrong.

thank you iomega n .truthseeker
The ans is given the same but i still don't understand what do they mean by mesial cusp.is it mean supporting cusp and if yes then what will b the ans for guiding cusp.

for the ans I also think rhomboidal but ans given rectangular so was confused.

 

[gytbdc]

q. In ideal condition distobuccal cusp of maxillary 2nd molar goes where?

Is this true that ML cusp of mand 1st molar goes in the lingual embrassure b/w max 2nd premolar n 1st molar?

 

[Truth seeker]

Its kinda confusing , i looked up kaplan , it says , something like, occlusal outline and occusal shape, now whats that supposed to mean ? there a table that am talking about !
and whats more , when you go on to read the text, it says pentagonal outline of Mand 1st molar (perm) and the table lists as hexagonal ???

can someone please be kind enough to suggest/ guide/provide info, where and how to get these occlusal shapes of all teeth correct .

You're welcome gytbdc,
mesial pertains to mesio-buccal / mesio-lingual cusps

hope this clears your doubt .

isnt this the universal tooth system thats used here , then acc to it, mesial of 3 , turns out to be mesial of max 1st molar and so that is most appropriate ,

iomega, agreed with the expln part but please ,refer to the question again and let us know

thanks again !
