The bottle of protective lacquer must be CLOSED immediately after each use. Air and warm temperatures thicken the protective lacquer, making a chemical bond on the mask surface impossible. Sealing the cap with wax is helpful to preserve the lacquer.

After applying the lacquer, place the prosthesis at room temperature on a dust-free plate in the oven, increasing the temperature to a maximum of 130 C for 10-15 minutes.

Correction-Repair Material

It is possible to correct a defect or tear in the mask. With a defect, such as impression error, a new impression of the appropriate part as well as the model is necessary. Clean the area to be repaired and apply activator liquid. Mix base and activator and apply where necessary on the model. Set the mask in place immediately, cover with a piece of foil, and apply light pressure. Polymerization can be helped by placing the mask in the oven for a few minutes.

Tears can be repaired in a similar manner on the original model.

Storage

Gingivamoll should be stored in a refrigerator at 15C / 60F and should be left at room temperature 30 minutes before use.

Technical Information

244 Blue Polishing Paste1

244 Blue Polishing Paste

Preat 244 Blue Polishing Paste is the finest single step polishing compound available. Water soluble for easy cleaning and elimination of staining to produce a high shine on acrylic, gold, composites, non-precious, and chrome cobalt alloys.

244 Blue is a high shine polish in stick form for polishing all acrylic denture base materials, flexible denture base materials, chrome cobalt alloys, gold alloys and composites. The polish may be used on felt wheels and cones, rag wheels, and buffs. Best results are achieved when used with either a goat hair and micro fiber mounted brush in a handpiece or lathe wheel.

The polish should be used at a slow speed of 1000 to 5000 rpm at a low to moderate pressure to eliminate excessive heat.

It is recommended that the user wear breathing and eye protection for personal safety.

Preat Denture Stippling Mandrel

Preat Denture Stippling Mandrel

Preat Denture Stippling Mandrel

The PREAT Stippling mandrel is designed for stippling processed denture base resins on full and partial dentures.

The ¼ inch shaft will fit most standard chucks on a dental lathe. The user should place 4 each of either a #2, #4, or #6 round straight handpiece or friction grip steel or carbide burs into the stippling mandrel and tighten them securely with the Allen wrench that is included with the stippling mandrel. Best results are achieved using dull or used burs.

The clustered, four-bur pattern develops a realistic patina on denture resin. The stippler is comfortable to use, as the vibration transmitted to your hand is reduced due to the even number of burs.

Run the lathe at a slow speed and use a light to moderate pressure on the denture base resin to produce a stippled surface to provide a natural appearance.

The user should wear both breathing and eye protection when using. It is also recommended to be used in front of vacuum.

The result is an effect that very closely mimics the natural stippled surface of tissue. Shorten the carbide burs before mounting them in the Stippler, bend them slightly, and either dull the cutting flute or use well worn burs in this device. It is up to you as to your desired effect–the Stippler makes quick work of a tedious job!

eFiber Bonding Technique

eFiber Bonding Technique

Clinical Technique

After acid etching, clean the area to be bonded using a pumice and water mix. Rinse with water and air dry. Use the composite bonding technique according to the bonding agent manufacturer’s instructions. Apply bonding agent to the entire tooth area to be bonded. Light cure the bonding agent as described by the manufacturer. Apply a think layer of flowable composite to the bonded teeth surfaces. Do not light cure the composite yet.

Re-activate the fiber wings with unfilled resin or monomer.

Place the pontic in place, with the fiber wings on the uncured flowable composite. Use the clear silicone tool to press and hold the fiber wings in place. Use the eFiber tool to block out the pontic area, and light cure the fiber wing for 5-10 seconds. Use the same technique to light cure one tooth/pontic area at a time.

Place flowable composite on the bonded fiber wings as well as the pontic area, and light cure one tooth/pontic area at a time for 40 seconds. Polish and finish the restoration as needed.

eFiber and Perma Mesh: General Information

HANDLING

eFiber is pre-wetted with both PMMA and Bis-GMA; do NOT wet this material. It is ready to use right out of the package.

clear silicone

eFiber

eFiber and Mesh Handling Instructions1

Foil

Paper backing

eFiber is light sensitive and comes packaged in a protective foil pouch. Please be sure to store the eFiber in the pouch, or out of the light, when not in use. eFiber is packaged in a clear silicone matrix, which may be used as a tool during fabrication. The fiber is sticky, and sometimes the fiber sticks to the paper backing on the silicone matrix.

If this happens, gently roll the fiber back into a bundle using your fingers, gloves are not mandatory.

eFiber and Mesh Handling Instructions2
eFiber and Mesh Handling Instructions3

You can touch the fiber, and do not need special tools or scissors to cut the fiber. The “four finger” cutting technique  is recommended for best results.

The PMMA in Perma Mesh needs to be wet, or activated, prior to using. Two choices:

  • When using Mesh with acrylic, wet with a very slurry/thin mix of self-cure acrylic.
  • When using Mesh with composite or light cure resins, wet with PREAT Light Cure Wetting Agent.

The Light Cure Wetting Agent requires more wetting time to activate the PMMA than self cure acrylic.

Always “wet” Perma Mesh on a clean surface. A plastic bag works well.

eFiber and Mesh Handling Instructions4
eFiber and Mesh Handling Instructions5

When the PMMA in the Mesh is thoroughly activated, the Mesh will be translucent

You do not need any special tools when working with Perma Mesh. Any sharp scissors will work fine to cut the Mesh.

Denture Repair with eFiber

eFiber and Mesh Handling Instructions6
eFiber and Mesh Handling Instructions7
eFiber and Mesh Handling Instructions8

Re-assemble the broken denture and make a matrix to hold in place. Measure and cut the appropriate length of eFiber needed to repair a midline fracture (recommended from cuspid to cuspid). Cut a groove at the junction of the teeth and acrylic. Paint a small amount of Bonding Adhesive in the groove. Place the eFiber into the groove, and light cure for 5 seconds per unit. Apply repair acrylic using the technique of choice, process, and polish to a high shine.

Provisional Bridge

eFiber and Mesh Handling Instructions9
eFiber and Mesh Handling Instructions10
eFiber and Mesh Handling Instructions11

For direct technique, make an impression prior to preparing the abutments. For indirect technique, wax the bridge on the model and make a putty matrix. Measure and cut a length of eFiber that will run the entire length of the bridge. Use the clear silicone to hold the eFiber in position, and light cure the eFiber through the clear silicone. Cut two or more small squares of Perma Mesh, and wet the Mesh with Light Cure Wetting Agent until the Mesh is translucent.

eFiber and Mesh Handling Instructions12
eFiber and Mesh Handling Instructions13
eFiber and Mesh Handling Instructions14

Fill the impression/matrix with the parent material chosen for the temporary bridge. Place the cured eFiber, and then the wet Perma Mesh, into the matrix last. The eFiber should run the length of the bridge, and the Mesh will be placed over the abutments. Process the bridge, and easily cut and grind any excess fibers. Polish and finish.

Surface Retained Periodontal Splinting

eFiber and Mesh Handling Instructions15
eFiber and Mesh Handling Instructions16
eFiber and Mesh Handling Instructions17

Use a rubber dam to isolate the area to be splinted. Clean the teeth, then acid etch and apply bonding agent, according
to the bonding agent manufacturer’s instructions. Use dental floss or wax rope to measure the length of eFiber needed.

Cut the appropriate length of eFiber. Place a thin (0.5mm) continuous layer of flowable composite over the teeth. Do not cure. Place the eFiber onto the composite. Use the stepper tool or silicone matrix to hold in place, and start at one end, light curing 5 seconds per tooth. Use the stepper to keep the adjacent tooth out of the light. Place another thin layer of flowable composite over the eFiber, and cure for 40 seconds per tooth. Polish and adjust the splint.

Chairside Light Cure Acrylic2

                            Access Drill

INDICATIONS

The Light Cure Acrylic Resin is appropriate for use in chairside pickup of most dental attachments into an overdenture or partial denture, where autopolymerizing resin, (self-curing acrylic), may cause negative patient reactions or pose difficulties in replacing denture attachments.

CONTRAINDICATIONS

The Light Cure Acrylic Resin Syringe is not appropriate for use in a case where attachments are being processed into a new denture by the dental laboratory.

FEATURES

Chairside Light Cure Acrylic Resin:

  • Clear and Tissue colored light cure acrylic resins prepackaged in handy, ready to use syringes.
  • The denture can be placed over the intra-oral attachment with less chance of movement due to the unobstructed attachment recess.
  • There is no rush to perform the important step of checking occlusion and proper seating of the patient’s appliance. When everything is correct, the denture remains in place while light cure acrylic resin is injected in and around the attachment through a small access hole.

Self-Curing Acrylic Resin:

  • Time consuming mixing is necessary. Possible negative patient reaction to the unpleasant taste and burning sensation related to liquid monomer.
  • Filling the denture attachment recessed with self-curing acrylic and then forcing it over the attachment can cause displacement of the attachment as well as “locking in” of the attachment.
  • A time factor exists when determining proper seating of denture intra orally while the self-curing acrylic resin proceeds to set up.
