SU-POR Porous Polyethylene
Facial Implants

Believing Is Achieving

The New Generation Biomaterial

SU-POR Surgical Implants are manufactured from linear high-density polyethylene which allows for tissue ingrowth because of its interconnecting open pore structure.  The firm nature of the material allows carving with a sharp instrument without collapsing the pore structure.  SU-POR Surgical Implants are available in blocks, sheets and preformed anatomical shapes that are intended for augmentation and restoration of the cranio-maxillofacial skeleton.

The porosity of SU-POR Surgical Implants is maintained large, with average pore sizes greater than 100 microns and pore volume in the 50% range (measured by Mercury Intrusion Porosimetry). Clinical experience and animal studies have shown that tissue will grow into the open pores of porous polyethylene.

The clinical significance of tissue ingrowth may vary with the application and implant site.  In vitro and in vivo biocompatibility studies have shown SU-POR Surgical Implants to be free from any observable systemic or cytotoxic effects.

 

SU-POR Advantages

  • MRI Safe; having established safety and compatibility of passive implants in magnetic resonance (MRI) environment
  • Easy to cut with a scalpel
  • Easy to bend into required shape
  • Superior suturability made possible by proprietary manufacturing process
  • Easy to fasten with screws
  • Overall a much easier implant for surgeons to us

 

Handling SU-POR

The success of any implant is dependent upon careful handling and proper surgical technique. Porous materials are particularly susceptible to contamination either by micro-organisms or foreign material.  To reduce the chance of contamination during preoperative handling, the highest level of aseptic care must be used.  Su-Por Surgical Implants should remain in the protective pouch until the implant site has been prepared.

To reduce the chances of contamination during preoperative handling, SU-POR Surgical Implants are provided double pouched and sterile.

 

Implant Preparation

Su-Por Surgical Implants are sold sterile and should never be re-sterilized.  Prior to handling the implant, operating room personnel should put on a clean pair of powder free gloves.  Keeping the implant in its protective packaging until time of implantation.  Upon opening the inner pouch, the implant should be placed in a sterile antibiotic solution of the surgeon’s preference.  Strict adherence to the principles of aseptic technique should be followed with these implants.  Proper surgical procedures and techniques are the responsibility of the medical professional.

 

Cutting

Su-Por Surgical Implants are able to be readily cut with surgical instruments.  The material may be carved using a scalpel, burr, or cut with scissor.  Care should be taken to smooth the edges of the implant where it transitions to bone.  Trim any poorly attached implant material from the edges.  After carving and sculpting is complete, wash the implant with sterile saline to remove any loose particles from its surface and edges.

 

Contouring & Moulding

One of the Su-Por qualities is that it is a highly pliable material and can be easily reshaped without the need to preheat the implant.  If additional reshaping is required, the implant can be submerged in a hot, sterile saline bath (82° – 100°c).  Having been heated, the implant will be more flexible allowing for modification to the shape.  If the implant cools and becomes difficult to bend, it should be returned to the hot saline.  Once the desired shape is obtained, the implant should be held in that shape and allowed to cool. A cold, sterile bath can be used to accelerate the cooling process.  Repeat the above steps if further molding is required

 

Implant Fixation

Stabilization and fixing of the implant, if desired, can be accomplished by means of proper rigid fixation techniques.  Advantages of stabilizing the implant are the ability to contour and finely modify the edges of the implant, in situ, after fixation.

Screw fixation

Screw will compress the implant to the bone and will allow the surgeon to sink the screw head evenly with the surface of the implant.

Suture Fixation

The surface of the implant can easily be penetrated with a cutting needle, enabling the surgeon to suture it to tissues or muscle.

 

SU-POR Implant Selection

Su-Por offers an extensive selection of anatomical shapes, sheets, blocks, and spheres.

SU-POR Complete Catalogue

SUPOR Patient Specific Implant Catalogue

 

Patient Specific Surgical Implants

The patient’s own CT scan data is transformed, designed and crafted into an implant that is then able to augment or correct the individual patient’s anatomical defects or trauma.

Soft tissue compensation

Su-Por is used to restore both bony surface and missing soft tissue anatomy

Contralateral restoration

Su-Por can be designed so that it can be used even if the defect cross the mid-line

Asymmetry

To achieve optimal results Su-Por designers often collaborate with the surgical team to ensure the implant provides desired fit and symmetry

 

SU-POR Regulatory Approvals

  • FDA approved for USA
  • CE certified for Europe
  • TGA registered for Australia
  • Su-Por is also registered in many other countries around the world
