  • Percutaneous biofixed medical implants
    Patent number: 6299930
    Abstract: Percutaneous implants are disclosed including a portion implantable into a patient, a dermal bonding region capable of forming a bond between the implant and a dermal layer of the patient after the implantable portion is implanted into the patient, and the dermal bonding region including a substrate with a discontinuous coating of particulate bioactive glass wherein the average spacing between the particles of bioactive glass is predetermined and at least about 20 microns prior to implantation into the patient. Also disclosed are bioactive coatings including a substrate and fibers and/or particles of bioactive glass distributed on the substrate with a predetermined average interfiber distance of at least about 20 microns.

  • Guided periodontal tissue regeneration
    Patent number: 4961707
    Abstract: A method and surgical implant article for enhancing the regeneration of periodontal connective tissue at tooth root surfaces exposed by periodontal surgery wherein the exposed root surfaces are covered with a surgical implant article which is a membrane which excludes contact between the root surfaces and gingival epithelium and gingival connective tissue but permits migration to the root surfaces of PDL cells, the membrane being constructed of a non-toxic, nonimmunogenic, bio-absorbable material.
