Which of the following statements is true?
The MORE the VERTICAL overlap, the TALLER the cusps MUST be
The MORE the HORIZONTAL overlap, the SHORTER the cusps MAY be
The LESS the VERTICAL overlap, SHORTER the cusps MUST be
The MORE the HORIZONTAL overlap, the TALLER the cusps MAY be

Could anyone please explain the role of the words MUST and MAY in answering this question.I am just confused...

I know that in incresed vertical overlap the cusps will be taller and in increased horizontal overlap the cusps will be shorter,but what difference this must and may make?could someone help me in clearing this doubt?

Which permenent teeth occlude with only one tooth in the opposite jaw,assuming ideal conditions exist?

a) Maxillary canine
b) mandibular central incisors

Can OCCLUDING be same as OPPOSING?
I know mandibular central incisors OPPOSE with only one tooth,but maxillary canine occlude with mandibular first premolar and oppose (just out of contact) mandibular canine.Is OPPOSING cosidered as a part of OCCLUSION?

 

[drdds]

Normally , the facial cusp tip of maxillary first premolar oppose facial embrasure between mandibular first and second premolar.

During lateral excursive movements, maxillary teeth move distolingually on the working side,am i right?lateral excursive is same as lateral protrusive,right?

so how it can be explained that , During lateral excursive movements, the facial cusp ridge of maxillary first premolar on working side oppose distal cusp ridge of first premolar and mesial cusp ridge of second premolar?

How to determine the side(Right or left side) in mandibular movement questions?
should we just look at the shapes of the teeth and determine the side or is there any other way?

How to determine the side(Right or left side) in mandibular movement questions?
should we just look at the shapes of the teeth and determine the side or is there any other way?

You can determine by the diagram, or even by the arrows.
Remeber if you see max teeth with arrows (the arrows point the mand movement) - that's the real movement, soif arrow point to the left, that's the left lateral movement.

if you see mand teeth the arrows will indentify the max movement, which will be opposite to the real (actual) movement of the mandible.

Hope this helps.

Thanks a lot for trying to make me understand bombshell,but its not very clear to me yet.
If i see a question with a diagram of 2molars and 2 premolars , and in the diagram it appears to be that the 2 arrows are directing buccally.they have mentioned that it indcate the direction of movement of mandibular teeth over maxillary teeth.So i understand that this mandibular movement is a lateral,working side.But about the side ,as the premolars are shown on the right of molars in the diagram,this will be of left lateral working side,right?
the answer given is right lateral working side.


Another question,mandibular teeth with 2 molars and 2 premolars on right side of molars is shown.and 2 arrows directing towards diastobuccal side .It indicate movement of maxillary teeth over mandibular teeth.I understand that its a non working ,lateral movement.but again i dont understand how it is right and not left.

Sorry if i have confused you....will be a great help if you could explain.
thanks

the answer given is right lateral working side.

It;s always easier to explain with example. So I will use yours.
So you said "diagram of 2molars and 2premolars"
First thing you should do is to determine which are those teeth - max/man left/right. For the sake of the example, say they are maxilary right Premolars and molars.

Then you look at the arrow: pointing bucal (that means that the mand teeth are moving bucal in regard to the maxilary teeth). Meaning that the mandible is moving to the bucal on the same side, meaning it is moving to the RIGHT (the teeth in the example are right)

It doesn't matter how the diagram (photo) of the teeth is presented, just as long as you can determine whether the teeth are in which dental arch and in which side.

If this still doesn't help - post again the whole example.

It again depends on Right or LEft teeth are presented. (see the above example)
Sorry if i have confused you....will be a great help if you could explain.

hi, i can have a solution for those mandibular movement questns..

when u hve a question, showing maxillary movements on mandibular teeth, just reverse the arrows , and then u can just make ur own mandible move, and then u will end with the correct answer, i tried it and beleive me , it takes just 10 seconds!!

thats another way of putting it.

Thanks A lot bombshell and Niraj for taking your time in explaining my doubt....

In the first part of my question the picture was of right maxillary posteriors,so i understand that the buccal arrows shows the right lateral working side.

In the second part of my question the picture was of left mandibular posteriors.Thus the distobuccal arrows shows maxillary movement.So by reversing it we get the mandibular movt,ie mesiobuccal.thus it shows nonworking lateral movement.About the side are they asking about the side to which mandible moves? or the side where nonworking movement takes place?In this case as it is showing the left mandibular posteriors...nonworking side is in the left,am i right?so answer should be left lateral nonworking side.

Thanks once again.

Glad that we cleared the first part of the questions.. 😉

All true till now.... 😉

thus it shows nonworking lateral movement. Yes,.
About the side are they asking about the side to which mandible moves? or the side where nonworking movement takes place?
The movement is the right (right side is the working side; left side is the non working side). Since they gave you the left post. mand molars, you have to pick an answer towards them. Meaning that the movement will be right lateral movement, but the side is going to be the nonworking side (Left nonworking side ).

In this case as it is showing the left mandibular posteriors...nonworking side is in the left,am i right?so answer should be left lateral nonworking side.

Thanks once again.

Does it clear your doubts?

Could anyone please clear my other 2 doubts in this thread,

1)about the relation of cuspal height and vertical and horizontal overlap.[Significance of Must and May]

2)In the premolar question above,maxilla will move distolingually,so i expected an answer which is more distally,not between first and second premolar...could anyone please help with tackling such types of occlusl questions in determining the cuspal positions?

hey bombshel..( dental anatomy in dekcs nombeer 50)
help pleaseeeeeeee with this pls :
there r 2 molars and 2 premolars (mand?) the arrows are to the left, mand teeth over max teeth, why the answer is right lat workin side????

another quest a drawin showin the arows indicte the direction of movment of the maxilary teeth over the mandibular teeth during this mandibular movement..

can u pls help with this i jusy cant get it????
lookin to hear from ya //// its in decks 2009-2010 da quest. 50

Hey, I emailed you just few minutes ago.. I don't have the decks, but I can help you with the questions by your example:

so your diagram shows mand teeth - that means that the arrows point the movement of the maxillary teeth (which is the UNTRUE direction, since the mandible only moves, so to make it easier - just reverse the arrows).

You are not saying left or right mand teeth so clearfy that before I explain you the rest of the case in details, but if the arrow points to the left (then reverse it to the RIGHT - that's the side of the movement), okay?

Now the nonworking/working part is easy - if arrows are pointing to the right (as in our case) as the movement is to the right it would be R working Movement (as in the asnwer you gave). From the answe I conclude that the teeth are the right lower premolars and molars on the diagram, right? Let me know if I guessed it correctly.

Could anyone please help me with this?

1) What muscle is used to move the jaw to the left?
a)Right lateral pterygoid
b)Left lateral pterygoid

The answer given is "left lateral pterygoid"

i thought it is right lateral.

which one is correct?


2) Which group of fibres of alveolodental ligament resist tilting,intrusive,extrusive and rotational forces.
Answer given is apical.
I think the answer should be alveolar crest group.[for all 4 movts as apical is only for extrusive and rotational].which one is correct answer?

Please help me with this question.

Which tooth is most likely to be an incisor with cingulum offset from center?
a)Maxillary central incisor
b)maxillary lateral incisor
c)mandibular lateral incisor
d)mandibular central incisor

The ans given is mandibular lateral incisor.
But i think maxillary central also has a cingulum offset from centre.
so, how to answer this?will be of great help if someone could clear my doubt.

What improves the anterior guidance movement
1.increase overjet ,decrease overbite
2.increase overjet, increase overbite
3.decrease overjet, increase overbite
4.decrease overjet, decrease overbite

 

[Truth seeker]

hi, i can have a solution for those mandibular movement questns..

Thanks a lot for sharing your tip Niraj,it surely helped...🙂

hi
am having trouble dealing with working and non-working movements pictures and related questions.
is there a place where i can solve more questions on these to check my understanding....on this topic?

 

[Hammered]

What improves the anterior guidance movement
1.increase overjet ,decrease overbite
2.increase overjet, increase overbite
3.decrease overjet, increase overbite
4.decrease overjet, decrease overbite

Anterior Guidance would be the influence of contacting surface of teeth on mandibular movement.
Overbite is the vertical distance by which the maxillary incisors overlap the mandibular incisors and Overjet is the horizontal distance between them.
And greater the overbite, taller the posterior cusps and greater the overjet shorter are the posterior cusps....so if i try to use this concept in this question......what would improve the anterior guidance
i think should be decrease overjet and increase overbite.
Please correct this with explanation if iam wrong.
Thanks
