Instructions to construct a VERSACRYL Tissue Clasp

Each VERSACRYL Laboratory kit contains:

• VERSACRYL Softener monomer
• VERSACRYL Hardener monomer
• VERSACRYL powder polymer

1. In a small jar, first mix Softener and Hardener and stir for 10 seconds. The recommended proportions for the tissue clasp is: 40% Softener to 60% Hardener. In the instructions, the ratios are expressed in 'drops' of each liquid.
   
   
2. Slowly add the VERSACRYL powder while stirring, until the consistency is light creamy (approx. 1.5 parts powder to 1 part liquid). Wait until the mixture slightly gels and can be securely applied in the proper area.
   
   
3. Two methods to construct a VERSACRYL Tissue clasp:

• Double-pack heat-cure into a new denture: flask, remove wax and pack denture with pink acrylic using a polyvinyl sheet. Press and re-open flask. Cut away the pressed tissue clasp and at least another 3 mm further into the denture periphery.
  Pack the void with the VERSACRYL mixture. Close flask, final press and process as usual.
  
  
• Self-cure onto a new or existing denture: cut back and prepare the surfaces by roughening and priming with Hardener using a brush. Quickly apply the VERSACRYL mixture to all contact areas, then shape the tissue clasp as the material slowly gels. Process as usual in a pressure cooker.

Note: when designing a tissue clasp, do not leave sharp edges, to prevent scraping the soft tissues while inserting or removing the partial denture.

Always carefully check the final amount of retention and adjust the length of the tissue clasp on a duplicate model using warm water to ensure proper function of the appliance.
