Dual-space technique for creating cement space in a cementation device for implant dentistry: A predictable chairside approach

Abstract

As residual excess cement in peri-implant tissues is a problem that can lead to implant failure, great care must be taken when delivering cement-retained crowns. Cement selection, prosthetic design, and cementation techniques can reduce the chances of having excess cement in peri-implant tissues. Multiple techniques have been described, but, in many, the cement space has been reproduced by unreliable means. The dual-space technique allows the clinician to fabricate an implant crown delivery device in which the cement space has been replicated in a predictable and straightforward manner. In this technique, light-body impression material is used to create the luting space before the fabrication of the device with bis-acryl resin.
