Versacryl Reline Kit
This unique product has been developed to create thermo-adjustable relines.
Imagine having the luxury to simply heat the denture and re-adjust the
fit in seconds? And if not satisfactory, it can be repeated to ensure
complete comfort for the patient.
VERSACRYL RELINE
softens in warm water and has a flexibility range between 50 and 95 degrees
Celsius.
This product
is not a common "soft reline" material, though at body temperature
it has a cushiony effect, while when heated it becomes very soft and adaptable
to soft tissues and teeth, over and over again (at room temperature the
reline will feel relatively hard to the touch).
VERSACRYL RELINE
is a cross-linked acrylic denture material, guaranteed to create a perfect
chemical bond with all other acrylics. It is available in heat cure and
in self-cure.
It is noteworthy
that no special equipment is required to use VERSACRYL, but it is recommended
to follow the instructions closely, until a "feel" for the material
has been developed.
Heat cure method
To add
reline to a new denture:
- flask
denture as usual
- pack pink
denture base with a spacer
- add a
polyvinyl sheet and trial press
- mix VERSACRYL
following enclosed directions
- open flask
and remove the spacer
- pack VERSACRYL
against monomer-primed acrylic
- close
flask, press and process as usual.
To cure
reline to an existing denture:
- trim
at least 2mm off the denture
- take impression
with silicon or rubber
- flask
denture as usual
- open flask
and remove impression material
- mix VERSACRYL
following enclosed directions
- roughen
bottom of the denture and prime well with monomer
- pack VERSACRYL,
close flask, press and process as usual.
Self cure
method
To add
a reline at chairside:
- trim
at least 2mm off the denture
- roughen
and prime well with monomer, preferably twice
- mix VERSACRYL
following enclosed directions
- quickly
apply a thin layer while still very liquid
- build
up evenly, seal the edges well and wait for VERSACRYL to gel
- place
in mouth, check bite and muscle mould
- remove
denture within 20 sec., cure in pressure cooker and finish.
To process
reline in a jig :
- follow
the same method as "heat cure to an existing denture"
- use jig
instead of flask, cure in pressure cooker and finish as usual.
For older
dentures, or to make certain the chemical bond will not be compromised
by contaminants, first add a thin layer of freshly mixed regular acrylic,
prime well with the appropriate monomer, then apply VERSACRYL as instructed.
DIRECTIONS:
Powder liquid
ratio: between 1,5 to 2 parts powder : 1 part liquid, by weight. Determine
whether the reline may be considered small, medium or large.
Using the
measuring cups, dispense:
Small reline 5ml liquid = 3 grams to 7ml powder = 5 grams
Medium reline 7ml liquid = 4.5 grams to 10ml powder = 7 grams
Large reline 10ml liquid = 7 grams to 17ml powder = 11 grams
Measuring
is most precise with an electronic weight scale, following the above ratios.
To achieve
the best results, same as for acrylics in general, heat cure is always
recommended over self cure, because it produces a more complete and stable
polymerization, giving the appliance a more impervious surface and therefore
a longer lifespan.
The self
cure is polymerized in a pressure cooker in lukewarm water at 20 to 25
psi. Heat cure is cured in conjunction with pink denture base and can
be done either in water, dry or in the microwave, following the manufacturer's
instructions.
Recommendations:
When VERSACRYL
engages into undercuts, it is recommended to thermo-insert (pre-heating
in warm water) as well as thermo-release the denture (rinse with warm
water)
On upper
dentures, only the ridges could be relined, not necessarily always the
palatal area too.
Polishing
VERSACRYL ANGEL RELINE acrylic is not different from regular denture base
acrylic, except more caution and cryogenics are recommended. Than, similar
to soft reline materials, VERSACRYL can be polished and high-shined after
freezing for 15 to 20 minutes, with a leather buff. This flattens the
surface molecules and produces a much more impervious surface.
Patient management is the primary practitioner's responsibility: it is
up to the practitioner to instruct the patient and to delegate only those
functions, deemed necessary for the well-being of the patient.
USEFUL APPLICATIONS:
- full lower
denture relines
- full upper
ridge and periphery relines
- partial
denture saddle relines
- to add
retention in interproximal undercuts
- can be
used as gasket- or internal clasps
- can be
used as retention over any attachment, implant abutment or bar
- can be
used as gum additions on bridgework
- can be
used to produce Virginia partials
- can be
used in conjunction with the VERSACRYL-Lock sublingual stabilizer wings
