title: In vitro study of cementation of cast splints on nonmobile and mobile teeth.
abstract: The marginal opening of a fixed splint on movable and firm abutments was investigated. Regular-body poly(vinyl siloxane) was used as a luting material to cement a three-unit, cast complete crown splint on three metal dies in an acrylic resin model. The middle abutment was set first in acrylic resin and subsequently in a displaceable material. The cement replica was recovered, measured, and compared. The mean cement thickness for the mobile displaceable abutment was significantly greater (P less than 0.001) than that of nonmobile teeth.
