When An Implant Fails
There are two major reasons for implant failure: postimplant infection and failure to achieve primary stability. Treat the infected implant as an infected tooth: remove the infected implant. The infection will resolve. When a failed implant is removed if indicated, explore the implant site. If there is no gross bony wall defect, a larger and/or longer implant can be placed immediately after thorough site debridement, followed by antibiotic soaking.
Implant Re-Placement can be delayed or immediate.
|12||No Primary Stability||Succeed||13||Change to Wider, Longer, Cylindrical Implant|
|2||Implant smaller than socket||No Return||3||Failure due to non-immediate||Succeed|
|4||Post-implant Infection||Sinus Lift||18||Low Insertion Torque Redo|
|30||Design Place Graft Submerge||Uncover||10||Low Torque, Immed. load||Redo|
|13||Narrow Mesiodistal Space||1 Piece, 2 Piece||18||Shallow Placement||Redo|
|13||1 Piece, Why Delayed?||21||Immediate Fails||Why|
|2||Immediate bone graft||18||Insidious Infection, Soft Bone|
|31||From 1 stage to 2 stage||6||Possible Buccal Plate Perforation||Fibrointegration|
|19||Periimplantitis-Induced Abscess||Immediate Replacement|
