title: New prosthetic restorative features of Ankylos implant system.
abstract: OBJECTIVE
  All oral implant systems rely on the abutment part of the implant to provide stability for the dental prosthetic. The Ankylos implant offers precisely machined, tapered-cone abutment (Morse taper) connection. This tapered abutment connection provides high resistance to bending and rotational torque during clinical function, which significantly reduces the possibilities of screw fracture or loosening.
  
  
  OBJECTIVE
  This report describes the design and mechanical construction characteristics of the Ankylos implant system that make it possible for the system to provide final restorations that are natural looking, esthetically acceptable, durable, and cost effective.
  
  
  METHODS
  Review of the clinical literature.
  
  
  RESULTS
  The clinical results of singletooth crowns borne on Ankylos implants in the lateral tooth region are excellent after a minimum of 5 years in function (mean = 6.3 years) compared with the high prosthetic complication rate with other systems. Abutment loosening occurred in only 1.3% of the 233 innovative implants restored with crowns that were designed with a physiologically shaped occlusal surface.
  
  
  CONCLUSIONS
  This implant system is exceptionally well suited for use in the restoration of missing natural teeth.
