I have spacing in upper arch due to missing 14.
13 has drifted distally and 16 is rotated to the mesial palatal.
Upper incisors to remain in starting position,
 will have maximum cortical anchorage thanks to Li bracket torque.

But what about the upper 6 band? POS says it should be R2TipD.
Is this correct? Step 3-4 required for space closure.
Will this band negate anchorage loss of the 6 due to mesial root tip?

It appears we have an oxymoron here.

We want distal crown tip/mesial rt tip in max anchorage cases to increase posterior anchorage,
yet for minimum anchorage will are told to use the same band prescription.

Please elaborate.

PS, I realise this will create a posterior asymmetry at the molar level. I am still
contemplating the extraction of a contralateral premolar, but that is another topic in itself

Thanks
Actually spoke to Don as he is here doing the course. He suggests placing menton 1 at the menton. It is apparently a point that is not measured

Hi,
by bending the palatal bar towards the palate you might have unwanted toothmovement in the teeth it is fixed to. Best is to take it off and check for distortion of the palatal bar by then putting it on only one tooth. If you see the other end is standing away from the second tooth you have distortion. Bend it to the desired form (that is it fits without pressure on both teeth and sits close but not touching the palat).
If this is not possible use a new one. I usually take an impression and make a model to prefit it in the lab before putting it in the patients mouth. 

Hi,

tracing the symphysis I place menton 1 on Menton, then the next point at the most curved lingual part of the symphysis and end point where the symphysis touches the traced lower incisor. There is a video on how Don McGann does this step by step which you can download fom the pos site. Hope this helps.

thanks everybody for the valuable information.
I got Cannon D 50 from Photomed with ringflash. great camera,grt pics.
My assistants love it .
Photomed company  is very helpful if u need any information even after u buy the product.

Very new to dental cad, I am doing a few tracing and am confused with Menton 1 on tracing symphysis. Can some please enlighten me
Thanks in Advance

I have a 10 yr old male pt. badly carious , swollen A,B. Ext # A, B 2 wks ago.
# 4, 5 will take atleast 6 mos to erupt.
 Instead of putting unilateral space maintainer from # 3-C, i put bilateral spacer like TPA from PAR lab.what i did wrong --not adapted the cross palatal bar close to palate. now that has created imprint on dorsal surface of tongue.
i tried to push the palatal bar towards palate , the boy said it feels better, but the distance of bar to palate is 2mm, pl adv what to do.
1 do nothing
2  Take it off and redo
Thanks.

Expansion is a viable option as long as the patient is prepared to wear retainers for life.
I wouldn't be game to take this pathway.

I believe full arch distalisation would give a better finish.
Skeletal pattern is mild open but VTO would show if it can be achieved.
He is already bidentally protrusive.

I am currently attempting upper/lower full arch distalisation on a skeletal open bite adult using TAD's,
not because she wants NE but because she is missing most of her molars.

I am seeing the patient in 1/12.
Will then take R and L photos.
