title: Flexible thermoplastic resin to add retention to tooth-supported stereolithographic surgical guides.
abstract: Surgical guides produced by stereolithography use hard resin. The hard resin prevents seating beyond the height of contour, hence these guides are not intrinsically retentive. By covering the guide with a flexible thermoplastic material that extends into the undercuts, the resulting guide now has a retentive feature. This allows it to maintain its position during surgery yet it can easily be removed and repositioned.
