Purpose: The aim of this study is to present a new procedure in dental practice to prevent aspiration or ingestion of restorations; this procedure is economical and applicable to many kinds of indirect restoration materials.Methods: The jig comprises three rings in a line and bends at a right angle at the central ring. It is made of autopolymerizing acrylic resin that is molded with a self-made elastic mold. A 30-cm length of dental floss is tied to the ring at one side. The ring at the other side is glued with cyanoacrylate onto the non-occlusal surface of the restoration. If the ring does not properly fit the surface, a small amount of autopolymerizing resin may be brushed on it before gluing.Results: After ensuring that the jig is fixed firm enough, the operators can try-in, adjust, and retrieve the restoration without concerns regarding aspiration/ingestion. After cementation, the jig can easily be removed from the restoration by using scalers.Conclusion: This procedure allows us to decrease the risk of aspiration and ingestion of restorations in daily dental practice.
