Prevest Denpro Accusil Putty & Light Body

Direction to Use

• Tray Selection : Accusil Putty may be used with a suitable metal tray, a firm disposable tray, or a custom tray. For maximum accuracy use rigid trays offering good retention. Use of tray adhesive is recommended.
• Dispensing : Allow Accusil Putty material to reach room temperature prior to use. Using the scoops provided, dispense equal quantities of base and catalyst.
• Note: Close jars immediately after use. Do not interchange base and catalyst screw caps or scoops.
• Mixing : Knead by hand until a uniform color is achieved.
• Note: Latex gloves should be removed and hands washed thoroughly before mixing. To obtain optimum physical properties, the mix should be completely homogenous (streak-free), usually in about 45 seconds.

Impression Procedure Two Phase/One Step Procedure(Putty wash technique)

•  If there is any debris or blood, clean field with air water spray.
•  Remove excess water with suction. Do not dessicate the tooth.
• Mix Accusil Light Body, (Regular Set), backfill the impression syringe or attach an intra oral tip to
  the end of the mix tip for direct intraoral syringing.
• Inject syringe mix into and around toothpreparations. It is suggested to syringe
  completely around the margins of the preparation, making sure to keep syringe tip within impression material. Do not blast with air.
• Accusil Light Body Impression Material’s hydrophilic properties improve adaptation to the
  tooth enabling better “wetting”.
• While syringing wash material, the assistant should mix the putty load the tray.
• Place Accusil Putty material directly into impression tray and dimple impression. (This
  technique ensures the least amount of air incorporation.) Seat tray. Retain impression in position until firmly set. (Note: The material sets faster in the mouth.) Check impression in the mouth not on the bench. Note: Latex gloves should be removed and hands washed thoroughly before checking. Be sure it is firm,resilient, and non-tacky before removal. The minimum removal time (tested according to A.D.A. Specification #19) is 5 minutes from start
  of mix.
• Remove impression by pulling slowly to break seal, then snap out along the long axis of the tooth. Rinse impression under cold water and blow dry. Do not store impression in direct sunlight. If the impression is to be shipped, use suitable packaging to preclude distortion.
• Technique Tip: Some residual moisture prior to syringing is acceptable.

Two Phase/Two Step Procedure

• If there is any debris or blood, clean field with air water spray.
• Remove excess water with suction. Do not dessicate tooth.
• Place a polyethylene spacer sheet over putty and seat tray slowly. (Note : if a polyethylene sheet is not used, relieve the entire impression to provide at least 2 mm of space for the Accusil Light Body, (Regular Set) material.)
• Allow impression to remain undisturbed until it has set firmly (five minutes from start of mix).
• Remove impression when it reaches a rubbery consistency.
• Remove polyethylene sheet from impression surface. The impression should be washed free of saliva and thoroughly air dried before use as a base for subsequent impressions.
• Select either Accusil Light Body, (Regular Set) as a wash material and mix.
• Syringe Accusil Light Body, (Regular Set) material evenly around prepared teeth and directly onto Accusil Putty impression. Replace in mouth and allow to set for 2 minutes 30 seconds
  to 3 minutes in the mouth (not including work time).
• Remove impression with a direct pull.
• Store impression at room temperature. Pour impression with stone or other die materials within 14 days.

Directions for Border Molding :

• Apply Tray Adhesive to the borders of the tray.
• Dispense equal amounts of base and catalyst onto a mixing pad and knead by hand until a uniform color is obtained – mixing time: 45 seconds. Note : Latex gloves should be removed and hands washed thoroughly.
• Roll the mix into a thin rope and apply uniformly to the tray borders.
• Instruct patient to perform the various functional movements necessary for conventional border molding techniques.
• Five minutes from start of mix, remove tray and examine borders. The addition of a small mix can be used if voids or deficient areas are present. Over-extensions can be easily removed with a scalpel blade.
• The final impression can be made with Accusil Light Body,(Regular Set).
