Impression techniques with the Solid (one piece) abutment:
For the Implant/Abutment direct impressions follow the same techniques as for regular crown impression.
Impression Sleeves IDB102-XX-XX could be used to facilitate impression quality (retract the gum) and/or to fabricate temporary restoration over it.
Transfer impression techniques for:
1. Full Analog (IDB-101-XX OR IDB-005-03 PLUS IDB-1-XX)
Pickup impression provides a transfer of the implant/abutment position from the oral cavity to the working cast. Heavy body or soft body/heavy body impression is taken; follow the same technique as for regular crown impression. Implant Analog/Abutment assembly (or full analog) inserted in to the impression and soft tissue model with the analog fabricated.
As a variation of the above technique, impression sleeve could be picked up with the impression and the analog inserted into the impression sleeve. No need to pack the impression cord. Restoration is fabricated on the analog. This procedure assures precise fit of the restoration.
Impression Sleeves IDB102-XX-XX are used to facilitate impression quality and/or fabricate temporary restoration over it.
2. Two piece Abutment (IDB-005-03) and Implant Analog (IDB-004- 01)
Pickup impression provides a transfer of the implant position from the oral cavity to the working cast.
Heavy body or soft body/heavy body impression is taken; follow the same technique as for regular crown impression. Two piece Abutment screwed in to the Implant Analog and inserted in to the impression. Soft tissue model with the analog fabricated. No need to pack the impression cord. Open or close tray technique could be used.
Two piece Abutment could be modified as needed on the model and transferred into the mouth utilizing a simple jig for positioning (see abutment placement)
3. Transfer Kit (IDB-005-XX)Transfer kit is used for pickup impression, providing the transfer of the implant position from the oral cavity to the working cast.
Example of the splinting impression copings with autopolymirizing acrylic resin for a transfer impression to ensure desirable results.
Example of open tray for transfer impression customized and checked in the mouth.
Impression is taken.
Once the (open tray) impression had been obtained, implant analogs (included in the transfer kit) were adapted and screwed onto the copings, which remained inside the impression.
Master model is casted. Restoration is being fabricated on the implant analogs. This procedure assures precise fit of the prosthesis.
Placement and transferring of the retentive caps
Retentive caps inserted into the denture base either on the model in the lab or intraoraly at the chair side.
1. Pick up and transferring impression to fabricate master cast with implant analogs
Fix retentive cap before taking impression.
Retention cap could be picked up with the impression. It is recommended to use very hard impression material to keep the right position of the cap. Two or more caps could be connected with autopolymirizing acrylic resin. Once the impression had been obtained, Ball Abutment screwed into the implant analog and inserted to the retentive cap, which remained inside the impression (or together inserted in to the impression).
Transfer Kit (IDB-005-XX) could be used for transferring Ball Abutments as well (see instructions).
2. Chair side transferring retention caps
Fixing retention cap before transferring in the mouth.
After retention caps are aligned, undercuts needed to be blocked. Light cured blocking resin used.
Try the prosthesis in the mouth and check if the spaces (for the caps) large enough. Fill the holes with the self-curing resin and position the prosthesis in the mouth. When the resin hardened, take away the prosthesis and eliminate blocking resin. Remove the resin excess.
