Product Description

The Open Screw Transfer for Implant H2.43 (902545) consists of two components:

- Cylindrical transfer sleeve
- Fastening screw (712012)
- Technical Specifications
- Diameter: 4.5 mm
- Height: 13 mm
- Material: Stainless steel
- Implant connection: Internal Hex H2.43

The transfer sleeve is a supragingival component featuring a precision-machined 2.43 mm internal hex connection. The sleeve engages the implant connection with a secure locking effect and is fixed directly to the implant using the fastening screw.
The transfer is installed and removed using a 1.27 mm hex driver (431412 or equivalent).

Compatible with:

- UNIQUE implants: 3.75 mm, 4.2 mm, 5.0 mm, 6.0 mm
- PERFECT implants: 4.2 mm, 5.0 mm, 6.0 mm
- PRIMA implants: 3.3 mm, 3.75 mm, 4.2 mm, 5.0 mm, 6.0 mm
- Other implant systems with internal connection H2.43

Warnings

- The product is intended for single-patient use only.
- The product is supplied non-sterile.
- Sterilization in an autoclave at 135°C (275°F) before clinical use is recommended.
- The dentist, maxillofacial surgeon, or dental technician must be familiar with the clinical protocol for using implant impression transfers.
- Improper handling or incorrect clinical use may affect impression accuracy and prosthetic outcomes.

Indications

The impression transfer is intended for use in implant prosthetics to accurately transfer the position of an osseointegrated implant from the oral cavity to a laboratory model using the open tray impression technique.

Contraindications

- Lack of implant osseointegration
- Allergy or hypersensitivity to metals
- Trismus of masticatory muscles
- Limited mouth opening
- Increased gag reflex

Procedure for Use

An open-tray impression using an implant transfer allows highly accurate transfer of the implant position from the oral cavity to the working model compared to a closed-tray impression.

Clinical Procedure

1. Remove the gingiva former using a 1.27 mm hex driver.
2. Insert the Open Screw Transfer H2.43 (902545) into the implant internal hex connection.
3. Insert the fastening screw (712012) through the hollow opening of the transfer and secure the transfer to the implant using a 1.27 mm hex driver.
4. Cover the occlusal opening of the fastening screw with wax to prevent impression material from entering the screw channel.
5. Prepare the impression tray with an occlusal opening corresponding to the position of the transfer screw.
6. Take the impression using the “sandwich” technique:
   - Low-viscosity material around the transfer
   - High-viscosity material in the tray
   - Medium-viscosity material may also be used when clinically appropriate.
7. Remove excess impression material from the occlusal access opening to expose the fastening screw.
8. After complete polymerization of the impression material, unscrew the fastening screw (712012) from the implant using a 1.27 mm hex driver.
9. Remove the impression together with the transfer from the oral cavity.
10. Attach the corresponding implant analogue H2.43 (920038 or equivalent) to the transfer using the fastening screw (712012).
11. Transfer the assembled impression to the dental laboratory.
12. The dental technician fabricates gingival imitation material around the implant analogue area and pours the impression using dental stone.
13. After complete hardening of the model, the fastening screw is unscrewed and the impression with transfer is separated from the laboratory analogue.
14. The implant analogue remains embedded within the cast, accurately reproducing the intraoral implant position.
15. The resulting master model is used for fabrication of the implant-supported prosthetic restoration.

Sterilization

The product is supplied non-sterile and must be sterilized before use in an autoclave at: 135°C (275°F)
Single-patient use only.

Storage

Store in a clean, dry environment at room temperature away from direct sunlight and contamination.
