What each complication means clinically.
Infection
Post-operative infection of the implant site. Drives re-operation, prolonged antibiotics, and hospital readmission. The dominant complication in conventional mesh / PEEK cranioplasty. Our porous titanium with native TiO₂ chemistry supports vascularised soft-tissue ingrowth, which provides a barrier to infection.
Re-operation (critical failure)
Re-operation for implant removal or replacement due to mechanical failure, infection, or exposure. The most costly complication. Driven by the structural integrity of the implant and its integration with the host.
Subcutaneous effusion
Fluid collection under the scalp flap. Common with PEEK due to its non-hydrophilic surface that resists tissue integration. Our titanium's hydrophilic surface and porous architecture allow tissue integration that reduces fluid accumulation.
Loosening / migration
Implant migration or fixation failure under physiological load. Driven by the mechanical performance of the implant. Our 1,400 N compressive strength and ≥ 5 × 10⁶ cycle fatigue resistance are an order of magnitude beyond mesh / PEEK.
The mechanism behind the numbers.
Material matters
Native TiO₂ + Ti-OH groups on titanium bind to human tissue proteins via hydrogen bonds and Ti-O-R covalent bonds. PEEK is hydrophobic, inert, and prone to biofilm formation. Mesh is a simpler form of titanium but lacks the engineered porous micro-architecture.
Structure matters
Our gradient porous micro-architecture supports vascularised bone ingrowth. Mesh has limited porosity. PEEK has no porosity. Vascularised ingrowth is what gives the implant biological fixation — not just mechanical fixation.
Geometry matters
1:1 patient-matched geometry eliminates intra-operative "try-fit, re-trim" loops. Less OR time, less soft-tissue trauma, less exposure to contamination. The 1:1 match is itself a complication-reduction strategy.
Lower complications = lower total cost of care.
For hospital procurement and HTA evaluation, the unit price of an implant is only one part of the cost-of-care picture. The complications avoided — and the re-operations, prolonged antibiotics, and readmissions they would have triggered — are often the larger cost.
Internal modelling, benchmarked against peer hospital cost data:
- Per-case complication management cost (titanium mesh): RMB 30,000 – 80,000
- Per-case complication management cost (PEEK plate): > RMB 50,000
- Per-case complication management cost (Excellent MedTech): < RMB 5,000
