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.
• Hydrophilic
• Allows for placement of the implant into antibiotic solution pre-operatively; enables vascular flow postoperatively
• Porous
• 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
• Radiopaque
• Implants can be conveniently and accurately monitored post-operatively
• Indications
