  • Title: New abutment for a screw-retained, implant-supported crown.
    Author: Prisco R, Morgano SM, D'amato S.
    Journal: J Prosthet Dent; 2001 Jan; 85(1):30-3. PubMed ID: 11174675.
    Abstract:
    The 1-piece, implant-supported abutment and crown, colloquially described as the UCLA abutment, commonly is used to fabricate single, screw-retained crowns. This abutment was designed to allow attachment of the crown directly to the implant and requires a waxing and casting procedure by a laboratory technician. A new prefabricated abutment has been developed that uses a similar approach but does not require the waxing and casting process. The PDQ abutment is made from a metal-ceramic alloy that is custom contoured by grinding to support a porcelain veneer. Porcelain then is fired to the contoured abutment to develop the 1-piece artificial crown. This article describes the use of the PDQ abutment.
