The immediate replacement of incisor teeth by cantilevered adhesive bridgework.

Adhesive bridgework is now an accepted alternative to conventional bridgework especially in teeth with minimal tooth substance loss and where occlusal forces are not excessive. Several designs have been described and these can be divided into bridges with perforated or non-perforated retainers. The perforated design was described by Rochette while the non-perforated design was pioneered by Livaditis and Thompson and became popularly known as the "Maryland bridge". It is now common practice to simply sandblast non-precious alloy retainers which are then bonded with specific chemically active adhesives.
