Encode® Impression System – Clinician Procedure

Encode® Impression System – Clinician Procedure

SURGEON
1. Select an Encode Healing Abutment with the appropriate restorative platform diameter, Emergence Profile (EP) and collar height.

NOTE: Use tall Encode Healing Abutments. The height of the abutment collar, not including the domed occlusal portion, should extend 2mm above the soft tissue (1mm minimum) on all sides for proper impressioning and subsequent scanning. Use wide Encode Healing Abutments to ensure that the final abutment will seat easily without excessive blanching of the tissue.

Place the Encode Healing Abutments. Ensure that the Encode Healing Abutments are fully seated on the implant with a radiograph. Encode Healing Abutments have a two piece design. The body of the healing abutment engages the hex connection of the implant. Bone profiling may be required to fully seat the
healing abutment. The Encode Healing Abutment Screw should be torqued to 20Ncm using the large hex driver tip. Suture the tissue around the Encode Healing Abutment and allow the tissue to completely heal.

After tissue maturation, the Encode Healing Abutment is ready for impressioning. Ensure that the Encode Healing Abutments are fully seated on the implant with a radiograph. The height of the abutment collar, not including the domed occlusal portion, should extend 2mm above the soft tissue (1mm minimum) on all sides. Hand tighten the Encode Healing Abutments before impressioning. Use a light body impression material around the healing abutment and medium body

elastomeric impression material (polyether or polyvinyl) in the impression tray and seat in the mouth. Allow the impressionmaterial to set per the manufacturer’s instructions.

After the impression material has set, remove the tray from the mouth. Verify that a clear impression (no rips, tears, bubbles or distortions) has been made of all the Encode Healing Abutment markings and the
entire circumference of the healing abutment. In addition, ensure that the tissue contours have been captured.

Make an impression of the opposing arch, a bite registration and select a shade for the crown. Disinfect and package the impressions and the bite registration. Ship to your participating ARCHITECH PSR Dental Laboratory.

NOTE: Larger cases of three or more units should include a diagnostic wax up. A metal or resin framework try in is recommended for multiple unit cases.

The laboratory delivers the final Encode Abutment, the restoration, the master cast with analogs in place and all other case materials to the restorative clinician. Encode Healing Abutments have a two piece design. First, remove the Encode Healing Abutment Screw using the Large Hex Driver. The body of the Encode
Healing Abutment can then be easily removed by pulling it from the implant.

Encode Abutments and components are not sterile when delivered. Autoclave prior to patient use. Steam autoclave sterilize in a single pouch for 40 minutes at a temperature of 270°F (132°C).

Certain Internal Connection): Activate the fingers on the Encode Abutment using the QuickSeat Activator Tool. Locate the tooth number on the buccal aspect of the abutment to orient the abutment position. Place the final Encode Abutment into the implant, line up the hex and press until feeling the
tactile click. Thread a Certain Gold-Tite Hexed Screw into the implant until finger tight.

External Connection: Locate the tooth number on the buccal aspect of the abutment to orient the abutment position. Place the final Encode Abutment onto the implant, engaging the hex. Thread a Square Gold-Tite Screw into the implant until finger-tight. Radiograph the interface to verify an accurate fit.

NOTE: If there is not enough space to create a number, a line will be placed on the buccal surface of the final Encode Abutment for orientation purposes.

Try in the restoration on the final Encode Abutment and check the occlusion, marginal fit and interproximal contacts. A metal framework try in is recommended for multiple unit cases. Remove the restoration. Make adjustments as necessary.

Certain Internal Connection: Torque the Certain Gold-Tite Screw to 20Ncm using the Large Hex Driver Tip and a torque device.

External Connection: Torque the Square Gold-Tite Screw to 32–35Ncm using the Square Driver Tip and a torque device.

NOTE: The Contra Angle Torque Driver (CATD0/NCATD0) is contra indicated for use with Zirconia Abutments. The Low Torque Indicating Ratchet Wrench (L-TIRW) or the Restorative Torque Indicator
(RTI) are recommended for use with zirconia abutments. Please see MKT407 for proper handling instructions of Encode Zirconia Abutments.

Place a protective material over the screw head. Seal the access hole with temporary filling material. Cement the restoration on the final Encode Abutment using a temporary or permanent cement.
