For reconstruction and augmentation in craniofacial procedures.
Hard tissue replacement (HTR)
The Hard Tissue Replacement polymer implants (HTR-PMMA) are intended for reconstruction and augmentation in craniofacial procedures. They are intended to fill voids or defects in the bone resulting from a disease, traumatic injury or a surgical trauma.
HTR-PMMA can be used in aesthetic reconstructive procedures where augmentation or change in bony contours is desired. Those devices are is a technology-driven, cranial patient-matched implant designed to achieve cosmesis of the skull resulting from tumor, trauma, or deformity.
The unique process of developing an HTR-PMMA implant converts patient CT-Scan data into 3-D images. These images are used to create anatomical models, which are then used to build the patient-matched implants.
HTR-PMMA is designed to provide:
- Four fit options
- Implant pre-plating
- Simplified CT data Transfer through FTP and PACs
- A porous implant that permits fibrovascular ingrowth and potential for bony attachment
- Hydrophilic properties which allow for pre-operative antibiotic solution bath
Distinct Features include:
- Patient Specific Anatomic Fit
- HTR-PMMA is designed and manufactured based on uncompressed DICOM CT data.
- Allows for placement of the implant into antibiotic solution pre-operatively; enables vascular flow postoperatively
- Pore diameter ranges from 150 – 350 microns supports possible connective tissue and bone ingrowth
- Rigid and Strong
- Implants have a rigidity similar to bone, with a compressive strength of 5,000 psi
- Negative Surface Charge
- May have minor positive effects on bony ingrowth and inhibition of bacterial adhesion
- Implants can be conveniently and accurately monitored post-operatively
