Product Description

The Closed Lock Wide Transfer for Implant Internal Hex 2.43 (901552) is intended for closed tray impression procedures and consists of two components:

- Cylindrical transfer sleeve
- Fastening screw (711112)

Technical Specifications

- Diameter: 5.5 mm
- Height: 13 mm
- Material: Stainless steel
- Implant connection: Internal Hex 2.43

The wide-profile 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 wide-body design provides enhanced stability and handling during impression procedures, particularly in restorations involving wider implant platforms and increased soft tissue volume.

The transfer is installed and removed using a 1.27 mm hex driver (431412 or equivalent).

The product is intended for taking impressions of osseointegrated implants with H2.43 internal connection, including:

- 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 H2.43 internal connection

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 or maxillofacial surgeon 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 closed 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

The closed tray impression technique allows accurate transfer of the implant position from the oral cavity to the working model.

Clinical Procedure

1. Remove the healing abutment or gingiva former using a 1.27 mm hex driver.
2. Insert the Closed Lock Wide Transfer H2.43 (901552) into the implant internal hex connection.
3. Insert the fastening screw (711112) 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 transfer with wax to prevent impression material from entering the screw channel.
5. Take the impression using the closed tray “sandwich” technique:
   - Low-viscosity material around the transfer
   - High-viscosity material in the tray
   - Medium-viscosity material may also be used when clinically appropriate.
6. After complete polymerization of the impression material, remove the impression from the oral cavity.
7. Using a 1.27 mm hex driver, unscrew the fastening screw (711112) and remove the transfer from the implant.
8. Attach the corresponding laboratory analogue for Internal Hex 2.43 implants to the transfer outside the oral cavity.
9. Insert the assembled “transfer + analogue” into the corresponding position within the impression.
10. Transfer the impression to the dental laboratory.
11. The dental technician fabricates gingival imitation material around the implant area and pours the impression using dental stone.
12. After separation of the impression from the model, the implant analogue remains positioned within the cast, accurately reproducing the intraoral implant position.
13. 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.
