rather than distalising the molar or tipping it distally, assuming low friction and sliding mechanics, wouldn't the spring just push the archwire around? Could you place another Gurin lock on the mesial of a bracket on the contralateral side to prevent the wire sliding and force the distalisation of tooth to occur instead of the archwire just sliding round..
That would be definitely be more likely to happen if using self ligating brackets. You do get some friction resisting archwire slide when using conventional ligation. Light activation of the OCS helps avoid overpowering that friction. In most of these situations the molar is mesially rotated so activating the spring will give distal rotation which also gives you space. If the concern is archwire slide as you said you could place another gurin lock on the contralateral side. Other options could be to use a dimpled archwire or perhaps to place a post on the archwire and add in a light class 3 elastic if moving a lower molar.
@@Powerprox thanks for the reply! that's interesting, a few things there for me to research. been binge watching your videos, great content. thank you!
There are world renowned ortho's who will place on 012 niti AW. You certainly do want the proper length of spring though to avoid unwanted tooth movements of the adjacent teeth.
Thank you Dr.. we appreciate this from you..
God bless you
Excellent explanation and to more progress ..congratulation from egypt .we wait more videos

Sir, on which sequence of wire we've to use open coil spring?
You can place OCS to make the initial space for a tooth on a .014 niti AW
Sir, but it 's flexible wire...
There are world renowned ortho's who will place on 012 niti AW. You certainly do want the proper length of spring though to avoid unwanted tooth movements of the adjacent teeth.
K.. Thank you sir.
What wire is suitable for spring and geurin?
More often than not can place on the 018
Can i use gurin lock as teeth moving mechanism such as canine destal shifting
Or molar mesial shifting
Can this method be alternative to TADs?
Yes, but unlike TADs with their absolute anchorage you do still have anchorage concerns to be mindful of.
how can i get all video
I have an educational website that currently has over 17 hours of video. www.SixMonthBraces.com/OnlineSeminars
