Some difficulty lies in keeping the soft tissues around the implant free of "Dura Lay" flowing so the impression light material can flow freely without being hindered by resin excess...if that occurs in such a sector like 16 17 18 , that can be quite difficult to have a good control of it...maybe putting some modeling wax there avoiding the resin excesses to flow around the Implant-transfert connexion area, easily removable after the resin has been set, can help.
Well we need to understand why we are doing this.. to make it super accurate implant position in the model for restoration. This will allow the abutment and prosthesis go in the most accurate way with the engaging hex inside. My question is how much angle of implant it can compensate to make custom abutments with screw retained prosthesis. If the implant angle is not as parallel then may need to go for multi angle abutment and do the same thing like in the video. If mistakes happens and pros does not fit then it is very expensive to fix for the lab work..
Actually its depends on number of implants.. if single implant are angulated then it can be managed with a normal angulated abutment till 30degree.. but in case if multiple implant are angulated then you have to use multiunit abutment for management.
i ve found a faster easier way for chairside , make resin sticks outside with many lenghts , when the patient comes put the pickups, measure the distance between them , take the appropriate stick readymade trim it as you want then just weild/splint it to the cylinder like attachment/connector 🙂
Of-course yes :), splinting with floss incorporated will give more strength for your resin framework. it will avoid unnecessary loosening and breaking of splinted impression post.
As we use a huge volume of Duralay here' polymerization shrinkage of Duralay resin during setting may be occurred so we should split it just before taking impression by a disc or hotted knife and fill the gap again to neutralise shrinkage.
hi Rajesh, adding bulk of pattern resin will create curing shrinkage that will add stress on splinting with will lead minor changes in position of splinted impression coping during removal of impression from the patient mouth. that will affect the quality of final impression. to relive the stress we have to split the splinting with small disk or burs and re-splint it with a small amount of resin material. this will prevent these adverse effect..
In some situations, the components can become cold-welded to the implant pegs due to metal-to-metal contact. To prevent this during the pickup impression, you can try making contact and removing the components once or twice before taking the final impression. This method helps avoid cold-welding of the components during impression making.
yes we can use composite for splinting in some simple cases.. but it has some limitation: light curing is not possible if we add composite in bulk leads to breakage of splinting.. if isolation is not properly done bonding and splinting fail..

Finally I understood how this works!! Great demo!
Glad it helped!
Great work..
YOU WON MY HEART . :) .. TOO GOOD .
thank you.. glad it was helpful.
Excellent....
Excellent demo
Very nice
Superb well explained
Glad you liked it

Which gloves do you use here
its a black nitrile gloves available in market..
why sectioning pattern resin required? please clear it

THIS TECHNIQUE depends on implant connetion design, that very deep and tight, like starumman cross fit, will LOCK IN the implant.

but I could make this in side mouth
i speake about floss&wax is it easy?
yes..:) practice makes your work easy and perfect.
Use composite instead of floss
yes we can use composite for splinting in some simple cases.. but it has some limitation: light curing is not possible if we add composite in bulk leads to breakage of splinting.. if isolation is not properly done bonding and splinting fail..
Just use heavy body throughout no need for this
hello dr, if its custom tray better use putty for better control.. if in case of custom tray heavy body is the choice.. thanks for your inputs..
