Possible complications that may occur with implant‐retained overdentures
| Complication type | Definitions | |
|---|---|---|
| Mechanical complications | ||
| 1 | Patrix loose | Patrix component refers to stud attachments and/or its components as screws, as well as all inter‐abutment and cantilever bars/superstructures (round, ovoid, U‐shaped, milled, spark eroded) |
| 2 | Patrix activated | |
| 3 | Patrix replaced | |
| 4 | Patrix fractured | |
| 5 | Dislodged, worn, or loose matrix, or its respective housing | Matrix refers to O ring, resilient cap attachment, and magnets, as well as all types of metal alloy or plastic bar clips (single sleeve or multiple sleeve) or permanent resilient lining material connecting to inter‐abutment or cantilevered bars/superstructures |
| 6 | Matrix activated | |
| 7 | Matrix replaced | |
| 8 | Matrix fractured | |
| Technical complications | ||
| 9 | Fractured implant overdenture | Puncture fracture of acrylic resin over patrix or fractured denture teeth |
| 10 | Reline of implant overdenture | |
| 11 | New implant overdenture reconstructed | |
