OBJECTIVETo get the information of patients' understand to the knowledge of artificial teeth prosthetics, provide reference for the propaganda of the prosthetic knowledge.

METHODS500 patients were chosen as the research objects. The survey about patients' understand to the knowledge of artificial teeth prosthetics was made with a reasonable questionnaire designed by us. The questionnaire contained nine sections. The questionnaires were filled in by the patients, dispatched and received by special messengers. The information of the questionnaires was analyzed and summarized.

RESULTS477 effective questionnaires were received. Patients were more familiar with the knowledge of the opportunity to get the oral prosthetic and less familiar with the knowledge of common problems after the oral prosthetic, the curing process before the oral prosthetic and the visiting times of the ordinary cure. However, they were not familiar with the knowledge of the basic concepts of the oral prosthetic, prosthetic materials and construction of dental prosthetic restoration and announcements after the oral prosthetic. They were most unfamiliar with the knowledge of common problems in the oral prosthetic process.

CONCLUSIONThe propaganda of the oral prosthetic should focus on the basic concepts of the oral prosthetic, prosthetic materials and construction of dental prosthetic restoration, common problems in the oral prosthetic process and announcements after the oral prosthetic. Meeting such problems, dentists should explain them to the patients patiently.
