Biodent® K+B Plus / OVS II
6. Characteristics
Material
Biodent K+B Plus is made of the dental plas tic IPN, a blend of selected polymers without
filler and with a high proportion of cross-Iinked particles . The proportions of the various
ingredients were formulated by computer to produce an ideal composition . The result was
"Interpenetrated Polymer Network" = IPN – a heterogeneous microstructure .
Advantages: crowns and veneers resistant to abrasion, tough, yet not brittle; no prob lems
with grinding; easy to bring quickly to a very high polish; permanently thick and smooth
surfaces; uniform curing temperature; reliable bonding of additional layers .
Colour
Biodent shades are easily and reliably obtained in the plastic veneer . Each shade has its
own dentine opaque and the shading of the bevelled layers is supported by nine different
neck opaques . The sheen and natural qualities of the finished Biodent K+B workpieces
have a further optical quality of natural teeth added to them: white fluorescence under
ultra-violet light!
Technique
Three different liquids enable the use of any of the following techniques:
Liquid S for the direct build-up method
Short doughing time (2–4 minutes at 22–30 °C) . Excellent plasticity, i .e . very easy to mould
and cut (not rubbery) . The dough is not tac ky and does not cob web . The materials do not
run into each other dur ing the layer ing but set quickly . No drying out, no formation of skin .
Ample working time (45 minutes) .
Cure: water bath at 95 °C, at least 15 minutes, pressure 6 bars .
Liquid N for flask method
Good fluidity, long working time .
Cure: heat up for about 30 minutes, then boil for 30 minutes .
Liquid K for cold cure
Sets quickly, short hardening time, only in conjunction with Promotor K .
Cure: 10 minutes in pressure flask at 40–50 °C .
OVS II Opaque
Liquid, ready to use, covers perfectly in a very thin film .
Drying time: 15 minutes at room temperature . This can be reduced to 5 minutes by warming .
