Collagen fiber anchoring platforms for percutaneous devices.

In this study, we investigated the use of perforated sheet platforms to improve the attachment of percutaneous devices to surrounding tissues. The model platform was created by a poly(methyl methacrylate) (PMMA) sheet with a matrix of 200-microm diameter perforations covering the groove (width, 3 mm; depth, 0.5 mm) prepared on the PMMA cylinder (diameter, 10 mm; length, 6 mm).

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

Objectives: Increase of soft tissue attachment is a major concern for improving the design of novel dental implants. This study evaluated the use of mesh structures placed on the implant surface for the anchorage of fibrous tissues.

Material And Methods: Specimens were prepared by covering their surfaces with a nylon mesh.
