Management of compromised residual alveolar ridges using hollow denture with three‑dimensional printed spacer and specialized impression technique

Abstract

Impression making in compromised residual alveolar ridge is a regular challenge in rehabilitating
patients with conventional removable complete dentures. In patients who cannot afford
implant‑supported dentures, specialized impression technique is a viable and justified option for
fabrication of complete dentures. More often, the stability of denture in such patients becomes a
deciding factor between failure and success. Furthermore, increased interarch space may result in
increased height of maxillary and/or mandibular dentures with corresponding increase in weight,
which further compromises the retention and stability of the prosthesis. This article describes
an amalgamation of Hobkirk’s impression technique in a case of resorbed maxillary residual
alveolar ridge with a flabby anterior segment and fabrication of hollow maxillary dentures using a
“three‑dimensional printed dental spacer” with a “double‑flask technique.” The weight of the final
prosthesis was reduced therefore contributing to improved retention and stability of the final
prosthesis.
Key Words: Double‑flask technique, Hobkirk’s impression techniques, hollow denture, three‑dimensional printed spacer
