Overdenture retention devices, overview

Key points

  • Implant overdenture attachment systems are comprised of two parts, one part connected to the implant/bar and the other within the prosthesis. The matrix is the receptacle component and a corresponding patrix fit closely either mechanically or by friction
  • Ball anchors and locators are popular since they offer simple protocols and can be built into existing or new prostheses
  • Bar constructions offer design flexibility for different situations and optimal prosthetic teeth positioning
  • Bar constructions offer more retention and stability, but more prevalence for mucositis because of reduced cleaning access
