The Rigid-Shield Technique: A New Contour and Clot Stabilizing Method for Ridge Preservation


Mattiola, Alessandro; Bosshardt, Dieter; Schmidlin, Patrick R (2018). The Rigid-Shield Technique: A New Contour and Clot Stabilizing Method for Ridge Preservation. Dentistry Journal, 6(2):21.

Abstract

Tooth extraction causes vertical and horizontal alveolar bone loss and consequent remodeling. Several methods have been introduced in terms of so-called “ridge preservation” techniques, which mostly resemble guided bone regenerative (GBR) procedures using filler materials and membranes in order to stabilize the respective sites. This conceptual case report describes a novel approach using a degradable polylactic acid membrane covered with a collagen matrix, which aims to reshape the resorbed alveolar wall and thereby to stabilize the soft tissues during matrix formation and socket mineralization. Clinical re-entry, radiographic (CBCT) and histologic evaluation proved adequate for osteoneogenesis despite an unfavorable initial situation: An implant could be ideally placed, which was circumferentially covered by bone. This minimally invasive method could offer a new method to approach socket preservation without using filler materials and coverage of the socket entrance. However, more controlled research on this topic is needed.
