Abstract: This paper reports on the digital restoration procedure of removable partial denture for a partially edentulous patient with limited mouth opening. The traditional tray impressions were difficult to complete for this patient. A digital intraoral scan was used to obtain digital impressions of the intraoral soft and hard tissues, and a computer-aided design and 3D printing technique were used to manufacture the diagnostic denture. The diagnostic denture was used to make final impressions and occlusal relationships and selective laser melting technology was used to produce a metal framework. The patient was satisfied with the restorative. This case provides a new way of thinking about the restorative process for partially edentulous patients with limited mouth opening.

Key words: limited mouth opening, removable partial denture, intraoral scan, diagnostic denture, selective laser melting
