Bi-V-Pin Plastic Sleeve 1000pc

• v-shaped profile suitable for use with close standing dies such as lower anteriors.



• only one drilling needed for each die.



• tapered shape glides easily into final position.



• open-ended sleeve prevents clogging and simplifies cleaning.



• reproducible positioning without vertical adjustment of bite.



• small base thanks to reduced pin length (12.5 mm).

Plastic sleeve
No more deformation of your intricate bridge copings through sudden, erratic loosing of pins thanks to Easy Glide function.

• remove without tension with a smooth, even gliding friction that runs along a special guide bar (see graphic).



• short friction distance of 1 mm (end position) allows the safe and simple removal of even the most complex bridge framework such as with diverging dies.



• a strain relief gap compensates any possible pin tolerance and provides a smooth and uniform friction with all pins.



• precision of fit and secure retention even after repeated insertion and retraction because the guide bar yields to the metal pin, thus there is no abrasion.



• retention marks in the plastic sleeve's outer surface secure them firmly in the model base.



• a membrane in the sleeve's lower exit area stops plaster from entering during base forming.



• custom plastic sleeves are dimensionally stable against moisture and heat (steam-cleaning).
