View Spec DetailsAddressing the growing demand for advanced biomechanical implants in Portugal’s premier central healthcare district.
Coimbra serves as the undisputed biomedical engine of Central Portugal (Região Centro). Anchored by prestigious institutions such as the Centro Hospitalar e Universitário de Coimbra (CHUC) and the historic Faculty of Medicine at the University of Coimbra, the region processes a high volume of complex craniomaxillofacial (CMF) trauma cases, oncological skull base resections, and pediatric reconstructive procedures.
To satisfy the stringent requirements of clinical specialists and public procurement frameworks under INFARMED (National Authority of Medicines and Health Products), surgical implants must demonstrate superior bio-inertness, customizable ductility, and optimal osteointegration capabilities.
Understanding the material science behind Hangzhou Retra Medical’s maxillofacial implants.
Our titanium meshes utilize Grade 5 Extra Low Interstitial (ELI) alloy (ASTM F136) for high-stress load-bearing structures such as mandibular reconstruction, providing high tensile strength (>860 MPa). For intricate orbital floor and mid-face reconstructions, unalloyed Grade 2 Titanium (ASTM F67) is utilized, offering superior manual bendability and zero memory recoil.
Engineered with a precise round and hexagonal 2D/3D hole matrix. The optimized pore diameter (1.2mm to 2.5mm) facilitates rapid neo-vascularization and fibroblastic ingrowth while maintaining rigid structural integrity to prevent soft tissue collapse into defect cavities.
Every mesh undergoes electrochemical anodization to form a chemically inert titanium oxide ($TiO_2$) passivation layer. This eliminates metal ion leaching, minimizes infection risks, and achieves complete corrosion immunity within bodily fluids.
| Implant Specification Type | Material Standard | Thickness Range | Screw Hole Diameter | Primary Clinical Indication |
|---|---|---|---|---|
| 2D Micro-Mesh Plate | Titanium Grade 2 (ASTM F67) | 0.4mm – 0.6mm | 1.5mm / 2.0mm | Orbital floor blowout, naso-ethmoid trauma |
| 3D Pre-Contoured Cranial Mesh | Titanium Grade 5 ELI (ASTM F136) | 0.6mm – 0.8mm | 2.0mm Self-Drilling | Large-scale cranial defect restoration |
| Rigid Mandibular Mesh Plate | Titanium Grade 5 ELI (ASTM F136) | 1.0mm – 1.5mm | 2.4mm Locking Screws | Mandibular segmental resection & load-bearing trauma |
| Anatomical Flower Mesh System | Titanium Grade 2 / Grade 5 mixed | 0.5mm – 0.7mm | 1.5mm / 2.0mm | Temporal & fronto-orbital defect contouring |

Pioneering digital workflow integration, patient-specific implants (PSI), and bio-interactive surfaces.
Integrating artificial intelligence algorithms with high-resolution CT/MRI scans allows surgeons in Coimbra to transmit raw DICOM files directly to Retra Medical's CAD engineering hub. Our team generates customized 3D patient-specific titanium mesh implants (PSI) within 48 hours, reducing operative times by up to 40%.
To combat hospital-acquired surgical site infections (SSI), Retra Medical is advancing nano-hydroxyapatite (nHA) and silver nanoparticle anodization technology. This bio-interactive surface promotes immediate bone cell attachment while exerting a localized antimicrobial effect against antibiotic-resistant strains.
Utilizing Selective Laser Melting (SLM) 3D titanium printing, Retra Medical constructs porous mesh structures with modulus of elasticity matched directly to human cortical bone (15–30 GPa), drastically reducing stress shielding risks compared to conventional solid metal plates.
Comprehensive surgical options engineered for rigid fixation, neuro-restoration, and pediatric CMF procedures.
Seamless supply chains guaranteed for hospital networks, surgical distributors, and OEM buyers in Coimbra.
Navigating the stringent European Union Medical Device Regulation (EU MDR 2017/745) requires complete transparency. Hangzhou Retra Medical supplies full technical documentation, including ISO 10993 biocompatibility testing (cytotoxicity, systemic toxicity, sensitization), cleanroom sterilization validation (ISO 11137), and comprehensive Risk Management Files according to ISO 14971.
Our products bear the CE mark, empowering Coimbra hospital purchasing departments and Portuguese medical importers to streamline local INFARMED registration.
We offer dual delivery formats to accommodate diverse clinical requirements: pre-sterilized double-blister sterile packaging ready for immediate operating theater use, or non-sterile bulk shipments designed for local central sterile supply departments (CSSD).
