The “salt and pepper” technique involves dipping a paint
brush into monomer (methyl methacrylate) followed by dipping the brush into
powder (PMMA) to form a bead of acrylic. It’s a very tedious and time-consuming
process of making or adding to an acrylic appliance, not to mention flasking
and processing for 8 hours.
Within the last few years, several light cure only acrylic versions
have come on to the market. These products are particularly useful for appliances
made outside of the mouth, such as pattern making. Some of these products, however,
still require very long curing times in special curing ovens from 5 – 40
minutes! Denali Corporation’s entry to the group is HIRO, a pattern, indexing
and registration material. It is light cured by dental wand type curing units
in less than 20 seconds! It is dimensionaly stable, can be added to itself and
allows continuous addition of material. As a pattern resin, HIRO burns out
completely and can be used in making PFM copings, cast crowns as well as implant
uses.

Denali’s next product in this arena is Jazzy, a Dual Cure
Acrylic. With Jazzy’s introduction, I am hard pressed to know why anyone would
want a light cure only product. I am told that some find using a double barrel
syringe to be too difficult, or simply want to take their time and light cure
only when they like. O.K. But once you have tried Jazzy Dual Cure, you will be
convinced of all its advantages and more. Jazzy can do several things in only a
few minutes that digital printing can only dream about, such as techniques that
are best done in the mouth! These include implant abutment registration,
implant guides, and pick-up of implant sleeves. Think accuracy counts in
implant dentistry?
Like all dual cure products, Jazzy comes in a double barrel
syringe with auto-mixing tips. Jazzy bonds well to other acrylics and
eliminates the odors of an open bottle of monomer or spills and waste clean-up
of excess material. Jazzy sets in about one minute in the mouth and can also be
cured on-demand.
As the name suggests we think it’s sophisticated, and
innovative, and did I mention is has no heat build-up, therefore no pain, so we
think its cool, too.
