UCLA Plastic Abutment
Prismatik Dentalcraft

Product Description

Inclusive 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. UCLA abutments are precisely machined from plastic or gold alloy and attached to the implant fixture (or implant analog) with a titanium screw or provisional guide pin. 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.

Plastic UCLAs will burn out completely during the casting process to create a monolithic abutment. For most implant systems, they are available with an engaging or non-engaging connection interface. Engaging UCLAs are indicated for single-unit restorations to prevent rotation. A non-engaging UCLA is indicated for multi-unit bridges to allow passive path of insertion without anti-rotational restrictions.

Gold UCLAs are available with an engaging connection interface only.


Each Inclusive UCLA Abutment is packaged with a separate provisional screw (Inclusive Guide Pin) and separate retaining screw (Inclusive Titanium Screw) compatible with the restorative instrumentation of the specified implant system. The guide pin should be used throughout the fabrication process. The titanium screw should only be utilized to retain the finished provisional.


The following conditions would contraindicate use of Inclusive UCLA Abutments: (a) wall thickness less than 0.5 mm; (b) gingival margin diameter less than 0.5 mm wider than the implant; (c) angle corrections of more than 20 degrees; (d) less than 0.5 mm margin height; (e) 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.


Inclusive UCLA Abutments are packaged NON-STERILE. Prior to use in the oral environment, they should be cleaned, disinfected, and sterilized according to an FDA-recognized sterility assurance standard such as ANSI/AAMI ST79.
