Abstract
A temporary alignment system, methods, and accessories for holding a dental coping to an implant abutment using a separable fastener using the same threads in the implant abutment used for definitive attachment are disclosed. The disclosed temporary fasteners initially orient and hold a coping against an implant abutment with a force along the same axis as the semi-definitive screw. The aligned coping can be picked-up in a closed-tray impression process without unscrewing the temporary fastener. Embodiments include threaded posts that release copings from the implant abutment through axial forces. Some embodiments include a threaded post with separable cap that is picked-up with the coping. Methods and accessories for using the separable fastener assembly or portions of it during conversion of an existing prosthesis for screw attachment or fabrication and fitting of a new prosthesis are described.
