Abstract: PURPOSE: To explore the diagnosis, basic characteristics and types of prosthodontic cases in different age groups, and to provide evidence for oral prosthodontic programs and oral health education for adults. Methods: A total of 11675 patients who visited the department of oral prosthodontics of Shanghai Minhang District Dental Disease Prevention and Treatment Center from April 2016 to October 2018 were derived from the information management system for the whole process of prosthodontics. SPSS 17.0 software package was used for statistical analysis. Results: Among 11675 cases of oral prosthodontics, the proportions of tooth defect, dentition defect and edentulism were 53.15%, 43.89% and 2.96%, respectively. With the increase of age, the proportions of defect restoration gradually decreased, and the proportions of dentition defect restoration gradually increased. The proportion of implant restoration in the group under 35 years old was higher than that of fixed bridge restoration. The proportion of restoration of tooth defect and fixed restoration of dentition defect in female was significantly higher than that in male (P<0.01). Among patients over 65 years old, 92.06% was removable denture. The proportion of porcelain fused to metal(67.16%) was higher than that of porcelain (32.37%) in fixed restoration. Among ceramic restoration colors selected by artificial vision colorimetry based on Vitapan 3D-master shade guide, group 3 (48.63%) accounted for the highest proportion,group 1 had the lowest proportion (0.65%), group 4 and group 5 accounted for the highest proportion in 45-54 year-old group. 3M2, 2M2, 2M3, 3M1 and 3R1.5 were shade selection with high frequency in the first 5 digits, while value in female was higher than that in male in the same age group. Conclusions: Timely restoration of dental defects can help delay the loss of teeth, and timely restoration of dentition defects can restore oral function, maintain the stability of dentition, prevent deterioration of oral condition, and promote oral health and overall health. It is suggested that prosthodontics should be added into community oral health education.
