Abstract

Purpose: The purpose of this study was to investigate the production environment of crown prosthesis for National Health Insurance(NHI) benefit. Methods: This study carried out self-administered questionnaire survey from September 1, 2016 to October 31 by having research subjects as 261 dental technician. Except 100 copies with incomplete response, 161 copies were used as the materials of final analysis. Results: Unlike gold crowns, the material cost of metal crowns was paid at the dental laboratory(86.3%). Total material consumption for making metal crown was more than gold crown(63.4%), especially for the finishing and polishing processes(78.3%). The subjects responded that a routine dental laboratory fee of crown prosthesis is unreasonable, and it is necessary to adjust and improve it(metal crown 96.2%, gold crown 96.9%). NHI coverage dental prosthesis was not marked on the order form(46.0%), and the dental laboratory fee of that was nor received(64.0%). Conclusion : It is necessary to estimate the NHI cost level of the crown prosthesis by reflecting the production environment and engineering process in dental laboratories. In addition, institutional arrangement should be backed up so that dental laboratories can receive appropriate dental laboratory fee.
