The SternSnap Attachment is indicated for use with dental implants to support and/or retain removable dental prostheses in the treatment of partially or totally edentulous patients to restore chewing function. The Stern Snap® attachment consists of a modified ball, which screws into an Abutment Base (alternatively the one-piece Stern Snap® Abutments may be screwed directly into an implant) and a retention cap, which is processed into the denture. The retention cap engages the outside of the ball shape and allows retention of the prosthesis to the denture.
A prefabricated device intended to provide a permanent intermediate fixture level between a dental implant and the final prosthesis/restoration (e.g., bridge, single tooth, overdenture). It includes one or more structural component(s) [e.g., abutment, ball, bar, bar overlay, coping, ring], and may be made of various materials [e.g., titanium (Ti), plastic, gold alloy]. It includes devices glued to prostheses and/or devices that can be replaced during cleaning cycles. An abutment screw(s) may be included, however the suprastructure does not represent the screw(s) in isolation. It may also be referred to as an abutment assembly or mesostructure.
