| Popis: |
Histologic examination of the tissues surrounding a titanium alloy basket implant and a hydroxyapatite-coated titanium cylinder implant from the mandible of a cadaver were examined. The 67-year-old man died 37 months after first-stage surgery from cardiovascular failure. Clinical and radiographic examinations indicated that the implants were functional, immobile, and integrated. Light microscopy revealed that the gingival tissues adjacent to the implants were healthy and, in general, free of inflammatory cells. The transmucosal area demonstrated a tight connective tissue apposition to the implants. The sulcular epithelial appearance was similar to that of a natural tooth. Histomorphometric analysis revealed that 72.2 percent of the basket implant and 75.3 percent of the hydroxyapatite-coated implant were in direct contact with bone. Generally, the bone along the surface of the basket implant was thicker than the bone along the surface of the hydroxyapatite-coated cylinder. Bone grew through the vent hole areas of both implants. |
