title: Space maintenance--a review of treatment options to repair the iatrogenic perforation.
abstract: Management of intra-canal and furcation perforations can pose a significant clinical challenge. In such cases a biological matrix can provide the framework for healing of injured periodontal tissues and will facilitate placement of the perforation repair material. As a consequence the long-term prognosis for treatment of the iatrogenic perforation can be significantly improved and the need for surgical intervention can often be eliminated.
