Product Description

Hahn Tapered Implant Universal Clearance-Limited Abutments (UCLAs) are indicated for laboratory use to manually create an implant-level custom abutment for a cement- or screw-retained restoration. A plastic sleeve mounted to the abutment provides a castable pattern on which to wax a custom abutment. Each UCLA is specific to the restorative platform of the seated implant.

• Precisely machined from gold alloy
• Feature a machined gold alloy base with plastic waxing sleeve
• Attach to the implant fixture (or implant analog) with a titanium screw or provisional guide pin
• These engaging UCLAs are indicated for single-unit restorations to prevent rotation.

Accessories

Each Hahn Tapered Implant UCLA is packaged with a separate provisional screw (Hahn Tapered Implant Guide Pin) and separate retaining screw (Hahn Tapered Implant Titanium Screw). The guide pin should be used throughout the fabrication process. The titanium screw should only be utilized to retain the finished provisional.

Contraindications

The following conditions would contraindicate use of Hahn Tapered Implant UCLAs:

• Wall thickness less than 0.5 mm
• Gingival margin diameter less than 0.5 mm wider than the implant
• Angle corrections of more than 30 degrees
• Less than 0.5 mm margin height
• Less than 4.0 mm abutment height

Angled abutments should not be used to restore small-diameter implants (less than or equal to 3.0 mm) in the posterior region.

Sterility

Hahn Tapered Implant UCLAs 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.

¹Oral disinfectant containing Chlorhexidine is recommended; refer to the disinfectant manufacturer's instructions. ²ANSI/AAMI ST79
