“…Supporting the epithelial layer and providing the vessels within the collagenous network, the connective tissue is of major importance for an effective sealing of the transepithelial breakthrough (Rompen et al 2006). Both the surface roughness/micro‐architecture and the material properties have been the main focus of in vivo investigations aiming at the improvement of the soft‐tissue attachment to implants (Abrahamsson et al 1996; Asoda et al 2008). It has been demonstrated that micro‐roughened titanium surfaces with grooves between 3 and 30 μm inhibit the epithelial down growth along the implant to a certain extent (Cheroudi et al 1990; Cheroudi et al 1992).…”

“…Such a use of the mesh may possibly aids the realization of an interface thinner than that obtained by using porous materials. In a previous report,12 we demonstrated that the collagen fibers from subcutaneous tissues were favorably anchored to a mesh with a 200‐μm spacing. The specimens were, however, completely submerged in the subcutaneous tissue and were in a different condition to that around of dental and maxillofacial implants.…”

“…The technology realizing the bonding of soft tissues to artificial materials will enable us to create a novel implant to which surrounding soft tissues will spontaneously attach. Although only few investigations have been reported on this subject, we recently have performed experiments12 to elucidate effective structure for the anchoring of collagen fibers. The animal experiments demonstrated that placement of a mesh with a spacing of approximately 200 μm on the implant's surface was favorable for soft tissue attachment.…”

Soft tissue attachment is a major concern for the improved design of dental and maxillofacial implants. This study evaluated the efficacy of mesh structures for soft tissue attachment in a rat percutaneous model. Four kinds of implant specimens were prepared - TI implants made of titanium cylinders, HA implants of hydroxyapatite-coated titanium, TI-Mesh implants with a titanium mesh covering a groove machined around a titanium cylinder, and similar HA-Mesh implants with a hydroxyapatite-coated mesh. These specimens were implanted percutaneously into the skin tissue of rats. The detachments of the implants were examined during the experimental period of 4 weeks. Survived implants were subjected to mechanical tests for the attachment strength and histological examinations. TI and HA implants demonstrated 0% of survival rates, while TI-Mesh and HA-Mesh showed significantly higher rates of 93.3% and 100% respectively. The attachment strengths were 159 ± 47 kPa in the TI-Mesh and 135 ± 16 kPa in the HA-Mesh. Histological observations revealed that collagen fibers originating from surrounding subcutaneous tissues were anchored to the mesh structures of the TI- and HA-Mesh implants. The results demonstrated the efficacy of the mesh structures for the attachment of soft connective tissues to implants.

“…The efficacy of mesh structures for the mechanical attachment of soft tissue to implants has also been demonstrated. Nylon or titanium mesh-coated titanium implants effectively attained an anchor in soft tissue following subcutaneous implantation in rats 9,10) . The fiber structures of collagens mainly consisted in gingival tissue and cementum around natural teeth.…”

Pilot study of gingival connective tissue responses to 3-dimensional collagen nanofiber-coated dental implants

The aim of the present study was to evaluate the gingival connective tissue response to screw-type titanium implants coated with Type I collagen nanofibers, which were prepared using the electrospray deposition method. Implants were immediately inserted into the socket of maxillary first molars after the extraction. Undecalcified sections after 4 weeks implantation were histologically observed. Better contact of the gingival connective tissue was generally observed around the collagen nanofiber-coated implants than titanium and non-fibrous collagen-immobilized implants. Gingival connective tissue to implant contact was significantly greater with the collagen nanofiber-coated implants than with the titanium and collagen-immobilized implants at the distal side, but not at the mesial side. Polarized light microscopy revealed that some birefringent collagen fiber bundles are oriented perpendicularly to the implant surfaces in the gingival connective tissue adjacent to the collagen nanofiber-coated implants. Collagen nanofiber-coating may have a possibility for improving gingival connective tissue response to titanium implants.

Mechanical attachment of soft fibrous tissues to implants by using mesh structures

Abstract: The efficiency of mesh structures for the attachment of soft tissues to implants was demonstrated. A mesh spacing of approximately 200 microm was observed to be favorable for the anchorage of fibrous tissues.
