Application of digital technology in the restoration of partial edentulous dentition with microstomia / 口腔疾病防治

ABSTRACT

Objective@# To explore the application of digital technology in the restoration of partial edentulous patients with microstomia. @*Methods@# A patient with microstomia was presented and seeking for the restoration of her full edentulous in the upper jaw and partial edentulous in the lower jaw (Kennedy Ⅲ). A digital intraoral scanning was used to obtain digital impressions of soft and hard tissues in the oral cavity. Computer aided design and 3D printing technology were used to design and fabricate the metal framework. @* Results @#The patient had no difficulty to wear or take off the dentures. The maxillary and mandibular dentures showed good retention, stability, mastication function and articulation. There was no tenderness in the one week and one month′s follow-up. And the chewing efficiency was satisfactory@*Conclusion@#This case report successfully designed and fabricated mandibular removable partial dentures for patients with microstomia through intraoral scanning and 3D printing technology. Thus, this work provides a new method and idea for treating partial edentulous dentition with microstomia
