Summary
Side-by-side
A simplified view. Each row is a general characteristic, not a guarantee for any individual patient.
| Material | How it's made | Grows into bone? | Imaging | Key evidence signal |
|---|---|---|---|---|
| Own bone (stored) | Saved from craniectomy | Living bone; may resorb | Normal | Resorption drives reoperation4,10 |
| PMMA | Hand-molded or prefabricated | No | Minimal interference | Mixed; higher infection in some NMAs11,12,13 |
| PEEK | Patient-specific | No | Minimal interference | Lowest revision in one NMA6 |
| Titanium mesh | Bent in surgery | Limited | Some CT artifact | Fewer hematomas, more exposure14 |
| Titanium PSI | Milled or 3D printed | Limited | Some CT artifact | Fewer complications vs standard implants15 |
| Hydroxyapatite | Custom porous ceramic | Yes, designed to integrate | Minimal interference | Integration, but brittle18,19 |
| Porous polyethylene | Sheets or custom | Soft-tissue ingrowth | Minimal interference | Low complications, mostly non-comparative data20 |
