title: [Investigation on 2317 working authorizations of fixed partial dentures].
abstract: OBJECTIVE
  The aim of the survey was to obtain the basic information of the working authorizations of fixed partial dentures so as to enhance the quality of professional cooperation between dentists and dental technicians in the future.
  
  
  METHODS
  2317 pieces of working authorizations of fixed partial dentures were divided into three groups according to the level of consignors. The filling of working authorization was recorded. The items in the questionnaire included the patients' information (name, gender, age and telephone number), design (design of occlusion, bridge, bottom crown, connector, and shade selection), sign and product date.
  
  
  RESULTS
  The statistical test showed there was significant difference in patients' age, telephone number and product date among these three groups. Dentists paid more attention to shade selection of anterior teeth than posterior teeth.
  
  
  CONCLUSIONS
  In this survey, the filling of working authorization of fixed partial dentures is generally ignored by dentists. The filling of working authorization should be strengthened.
