Harvest EasyGum® and All-in-One Bond - Instructions for Use

(en) Instructions for Use – EasyGum™ Composite Strips (for All-in-One Bond, see below)

Indications 

Harvest EasyGum® is indicated for adding texture and color to the gingival area of a dental base for removable dentures. This composite is bondable to typical acrylic denture resins used for making bases, such as polymethylmethacrylate (PMMA), as well as metals and ceramics (zirconia). The EasyGum™ Strip is an alternative to the laborious method of using a shaded composite paste to manually build up and model visible gingival surfaces to look similar to natural gingival issues. Additional texturization and coloration can be added using various shades of EasyGum™ Modifiers. The Strip is bonded to the base utilizing EasyGum™ Bond, and after any final detailing is to be cured utilizing a typical light curing device. EasyGum™ is intended to be used by dental lab technicians and approved by licensed practitioners before being provided to the patient. 

Contraindications:

EasyGum™ may only be used for its intended purpose. Any other use is strictly prohibited, and sole responsibility lies with the user. This product must not be used in patients with known allergies to any of its ingredients.

Use Instructions 

A. Cleaning 
    Roughen up base surface to be covered using a crosscut bur or sandblasting with aluminum oxide to enhance adhesion. Thoroughly clean to remove any dust and debris. 

B. Preparing for Bonding 
    Apply and prepare EasyGum™ Bond to bonding areas according to Instructions For Use (for All-in-One Bond, see below). If desired, gingival characterization of the dental base material utilizing EasyGum™ Modifiers can be completed now prior to the application of the Strip.  

C. Application 
   Select EasyGum™ with the desired shading that, when cured, matches natural gingival issues. Cut the Strip to roughly the overall size needed and apply to the base with minor pressure to attain basic adhesion. 

D. Trimming and Finishing 
    Trim the Strip to the desired shape, and finish with typical hand tools to include the appropriate features such as the gingival line and interdental papilla. EasyGum™ Modifiers can be applied and modelled for additional texture and enhanced coloration to closely resemble the natural gingiva. 

E. Light Curing 
    Light cure using a standard dental light curing unit according to the following and the light manufacturer’s
     instructions:  

  In cases where the gingival area is large and using a directed light source, light-cure the Strip in segments. 

F. Contouring and Polishing
 After light-curing, contour, and polish EasyGum™ as needed using typical methods.

Cautions:
 Avoid contact with eyes. If the material comes into contact with the eyes, flush with copious amounts of water and seek medical attention. Unpolymerized resins may cause skin sensitization in susceptible persons, in case of contact with the skin, wash thoroughly with soap and water.

General Instructions:

1. Rinse the preparation thoroughly and remove any pooled water. Leave moist.
2. Dispense a drop of EasyGum™ Bond into the cavity of the enclosed mixing well. Using a bristle brush applicator, apply 1 coat of EasyGum™ Bond to the entire preparation to be bonded to allow material to dwell for twenty seconds. DO NOT DRY.
3. Using the remaining material in the well and same applicator, apply 2 additional coats of EasyGum™ Bond.
