Product Description

Hahn Tapered Implant Open-Tray Impression Copings are used to transmit the position, angulation, and connection feature orientation of seated implants when captured in an elastomeric impression. Hahn Tapered Implant Open-Tray Impression Copings are prefabricated prosthetic components directly connected to endosseous dental implants for the purpose of capturing implant position in an elastomeric impression of the mandible or maxilla. Impression copings are precisely machined from titanium alloy and attached to the implant fixture by a titanium screw or guide pin. Each impression coping is specific to the restorative platform of the seated implant, as well as the transfer technique and desired emergence profile.

Open-tray impression copings are for use when using a direct transfer technique. It is important to use the appropriate impression coping for the transfer technique employed. Using a closed-tray impression coping with an open tray will result in an unreliable transfer, as the lack of undercuts on the closed-tray coping do not impress a vertical stop for repositioning the coping without the surface of a closed tray.

Accessories

Each Hahn Tapered Implant Open-Tray Impression Coping comes packaged with an open-tray retaining screw and a provisional guide pin. The guide pin should be used throughout the transfer process, while the open-tray retaining screw should only be utilized to affix the appropriate implant analog prior to delivery to the laboratory technician.

Contraindications

Hahn Tapered Implant Open-Tray Impression Copings should not be used for digital impressions captured with an intraoral scanner. It is important to use the appropriate impression coping for the transfer technique employed. Using a closed-tray impression coping with an open tray will result in an unreliable transfer, as the lack of undercuts on the closed-tray coping do not impress a vertical stop for repositioning the coping without the surface of a closed tray.

Sterility

Hahn Tapered Implant Open-Tray Impression Copings are shipped NON-STERILE. Non-sterile items must be cleaned, disinfected, and sterilized prior to clinical use, according to a validated method.

• Cleaning: Wash using a broad spectrum cleaning solution, followed by thorough rinsing and drying.

The recommended disinfection process is based on ANSI/AAMI ST79 guidelines, as follows:

• Disinfection: Immerse abutments in disinfectant¹, rinse with distilled water and dry.

The recommended sterilization process is based on the ANSI/AAMI/ISO 17665-1 and ANSI/AAMI ST79 guidelines, as follows:

• Sterilization: Gravity-fed sterilizers: Autoclave in sterilization pouch for 30 minutes at 121°C (250°F)². Devices are to be used immediately after sterilization.

NOTE: The validated procedures require the use of FDA-cleared sterilization trays, wraps, biological indicators, chemical indicators, and other sterilization accessories labeled for the sterilization cycle recommended. The healthcare facility should monitor the sterilizer for the facility according to an FDA-recognized sterility assurance standard such as ANSI/AAMI ST79.
