The flexible augmented flange technique for fabricating complete denture record bases

A technique for fabricating complete denture record bases that features flanges augmented with resilient liner is reintroduced and recommended. It is coined the flexible augmented flange technique. The technique takes advantage of the elastic properties of tissue conditioner, available anatomic undercuts in definitive casts, and the rigidity of record base resin to create stable, retentive, well-fitting, and comfortable record bases that minimally abrade casts. Tissue conditioner, which strongly bonds to the intaglio surface of record base flanges, replaces blockout wax to form augmented flanges with flexible inner sections that are sufficiently elastic to engage and then release from undercuts. The flexibility of the inner section of the flanges permits atraumatic insertion and removal from a patient's mouth, despite overall record base rigidity. Accurate, verifiable, maxillomandibular jaw relation records can be obtained with the flexible augmented flange technique.
