All on Four Rehabilitation in the Edentulous Arch: Team Approach (preview)


  • Complete edentulous population comprises more than 10% of the adult population and is directly related to the age of the patient, almost 45% has no teeth in either arch. Many of those patients with edentulous arches have been treated with an implant overdenture, some might have preferred a fixed prosthesis, but often for financial considerations they chose to have a removable prostheses instead.


  • The participants should be able to describe the indications and contraindications for a “All on Four Rehabilitation”.
  • Prosthetic and surgical guidelines will be provided for restorations of the edentulous arch.
  • Offer the clinician pearls and pitfalls about patient evaluation, treatment planning, implant placement guides, immediate loading protocol and final restoration.
  • Fixed- detachable hybrid prostheses are less expensive than Complete-arch rehabilitation porcelain-fused- to- metal Fixed dental Prostheses and the access holes allow screw tightening or retrieval of the prosthesis.
  • Extensive residual ridge resorption is one of the many problems in Prosthetic dentistry rehabilitation, especially in the posterior mandible. In order to overcome such limitation, different therapeutic alternatives have been proposed.
