Stented Porcine Collagen Matrix to Treat Inadequate Facial Attached Tissue of Dental Implant Supported Fixed Partial Dentures

Figure 1. Implant-supported crowns with inadequate facial immobile tissue (Patient TW). Figure 2. The facial mucosa is demonstrated with compression using a probe. Figure 3. A partial-thickness surgical wound is created to accept the porcine collagen. Figure 4. Bleeding is controlled with a saturated aqueous tranexamic acid tamponade. Figure 5. A festooned segment of porcine collagen fits into the wound and is covered with the bis-acryl before the collagen becomes saturated with blood. Figure 6. The bis-acryl is gingerly placed over the site directly from the mixing gun. The tip is cut and flattened to produce a ribbon of material to cover the site without significant creases or surface cavities. Figure 7. The site at the first postoperative week. Figure 8. The site at 8 postoperative months.
