SU-POR Surgical Implants are manufactured from a linear high-density polyethylene. SU-POR Surgical Implants allow for tissue ingrowth because of the 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, available in blocks, sheets and preformed anatomical shapes are intended for non-weight bearing applications of craniofacial reconstruction/cosmetic surgery and repair of craniofacial trauma. SU-POR Surgical Implants are also intended for augmentation and restoration of contour in the craniomaxillofacial 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. Invitro and invivo biocompatibility studies have shown SU-POR Surgical Implants to be free from any observable systemic or cytotoxic effects.

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. In order 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.

Select from an array of anatomical shapes, sheets, blocks, and spheres including:

  •  Preformed shapes for chin, malar, rim, midface and mandibular augmentation
  •  Reconstructive shapes for traumatic defects
  •  Sheets, wedges and blocks for orbital floor and wall repair
  •  Spheres and Conical Orbital Implants for enucleation and evisceration procedures

The intent of this brochure is to provide the surgeon with illustrations and dimensions of the many shapes of SU-POR Surgical Implants. Implants can be customized to accommodate the individual need of the patient.

Surgeons should utilize proper surgical techniques for which they were trained and their clinical experience to determine appropriate surgical procedures. Successful implantations are technique sensitive. Sound surgical judgment should be used in the selection/shaping and implantation of SU-POR Surgical Implants.

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. Keep 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 necessarily the responsibility of the medical professional.


SU-POR Surgical Implants are readily cut with surgical instruments. The material may be carved using scalpel, burr, or cut with scissors, 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 & Molding

To help the shaping process, the implant can be submerged in a hot, sterile saline bath (82° - 100°C, 180° - 212°F). 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 Stabilization

Stabilization and fixing of the implant, if desired, can be accomplished by means of proper rigid fixation techniques. For screw fixation, the screw will compress the implant to the bone and will allow the surgeon to sink the screw head even with the surface of the implant. The surface of the implant can easily be penetrated with a cutting needle, enabling the surgeon to suture it to tissues or muscle. Advantages of stabilizing the implant are the ability to contour and finely modify the edges of the implant, in situ, after fixation.

Surgical Revisions

The porous nature of SU-POR Surgical Implants allows for soft tissue ingrowth and vascularization of the implant. In patients that may require later surgical revision, the surgeon should be aware of this vascular and soft tissue ingrowth. In the event revision or removal of the implant is required after ingrowth has occurred, the surrounding soft tissue may be raised with a surgical instrument and the implant dissected out with a scalpel or surgical scissors.
