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:

  1. flask denture as usual
  2. pack pink denture base with a spacer
  3. add a polyvinyl sheet and trial press
  4. mix VERSACRYL following enclosed directions
  5. open flask and remove the spacer
  6. pack VERSACRYL against monomer-primed acrylic
  7. close flask, press and process as usual.

To cure reline to an existing denture:

  1. trim at least 2mm off the denture
  2. take impression with silicon or rubber
  3. flask denture as usual
  4. open flask and remove impression material
  5. mix VERSACRYL following enclosed directions
  6. roughen bottom of the denture and prime well with monomer
  7. pack VERSACRYL, close flask, press and process as usual.

Self cure method

To add a reline at chairside:

  1. trim at least 2mm off the denture
  2. roughen and prime well with monomer, preferably twice
  3. mix VERSACRYL following enclosed directions
  4. quickly apply a thin layer while still very liquid
  5. build up evenly, seal the edges well and wait for VERSACRYL to gel
  6. place in mouth, check bite and muscle mould
  7. remove denture within 20 sec., cure in pressure cooker and finish.

To process reline in a jig :

  1. follow the same method as "heat cure to an existing denture"
  2. 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
