Immediate function in the edentulous mandible: Replacement of a lost implant using prefabricated guides

Prosthetic Requirements for Immediate Implant Loading: A Review

“…The Branemark Novum (Nobel Biocare, Zurich, Switzerland) introduced in 1999 provided an edentulous patient with a full fixed implant‐supported mandibular prosthesis on the same day. The system consisted of immediately loading three implants in the interforamina region 2,107,108 . It was necessary to prepare the definitive prosthesis according to recordings prior to surgery and to provide a pre‐manufactured Ti bar screwed on the implant fixtures during the surgery; however, the system had limitations.…”

Its usage was limited to specific patients because of the anatomic variations found in their mouth and the possible prosthetic recording difficulties.…”

Retrieval Technique for Full‐Arch Implant‐Supported Fixed Prosthesis: A Clinical Report

“…When an osseointegrated implant is lost, it is generally necessary to replace the failed implant. Sometimes the implant can be removed without making an incision, using only the torque driver in a counterclockwise direction . However, before the new implants have been placed, the soft tissue and inflammatory debris should be removed from the failed implant site until all the bony walls feel solid.…”

“…The placement of the new implant should then be postponed until the bone has healed. In the event of an infection, the removal of the implant prior to the replacement procedure will delay the process, and interim prosthetic solutions must be used . Regardless of whether there is immediate or later replacement, the management of implant‐supported fixed prosthodontics in an implant failure situation usually increases the complexity of the solution to the clinical problem; however, rescue procedures using the same prostheses frequently decrease the cost and time required.…”

“…In the case of a failed implant, the techniques described here present several advantages, including a relatively simple technique and a low‐cost solution. The placement of wider implants in an ideal position maintained the tripod support at the implant level, by not being in line, improving the load distribution on these implants, especially in excursive movements . It also made possible the use of preexisting prostheses and, thus, efficiently solved the problem.…”
