Use of intraoral scanning and 3-dimensional printing in the fabrication of a removable partial denture for a patient with limited mouth opening.
J Am Dent Assoc. 2017 Mar 5. pii: S0002-8177(17)30083-1. doi: 10.1016/j.adaj.2017.01.022. [Epub ahead of print]
BACKGROUND AND OVERVIEW:
treating patients with severely limited mouth openings, it is difficult
for the dentist to obtain an impression and fabricate a removable
partial denture (RPD) by using traditional methods. Intraoral scanning,
computer-aided design, and 3-dimensional (3D) printing have provided
alternative methods for fabricating dental prostheses.
authors present a case in which they aimed to improve the efficiency
and quality of fabricating an RPD framework by integrating the
technologies of intraoral scanning, computer-aided design, and 3D
printing. Initially, the authors reconstructed the digital cast with
multiple intraoral scans. Subsequently, the authors designed the virtual
RPD framework. On the basis of the virtual framework, the titanium
alloy framework was fabricated by means of a 3D printing process, and
the authors fitted the final RPD to the patient.
CONCLUSIONS AND PRACTICAL IMPLICATIONS:
the traditional method, this integrated system has the potential to
design a custom-made dental prosthesis and directly make an RPD
framework with complicated patterns.
