Bar attachment system
Specific design of an attachment in which the patrix spans a specified width that the matrix matches. Each element is part of a prosthetic structure that spans two or more natural teeth and/or implants and is fixed intraorally with the matrix, which is incorporated within the prosthesis. Once the components are engaged by riders, clips,…

Bar
Round, half‐round, or elliptically shaped metallic segment with greater length than width. A bar is commonly used to connect components of a prosthesis such as abutments, crowns, or parts of a removable partial denture. It also can be used to provide support, stability, and/or retention for a prosthesis. A metal piece attaching two or more…

Ball attachment system
Specific design of a mechanical attachment in which the patrix fits into the matrix in a ball‐and‐socket type of relation. Each element is incorporated into either the natural tooth as part of a restoration or as an abutment on the implant with the reciprocal element incorporated into the prosthesis. The patrix, or ball, can be…
