[Statistical survey of prosthetic restorations--fixed and removable prosthesis].
This is a continued report on the statistical classification of the prosthetic restorations placed in the outpatients in the Tokyo Medical and Dental University Hospital. The data were collected from the laboratory records during the period of January to June of 1986. The results are summarized as follows: 1. Total of 419 bridges, consisting of nearly the same number in the maxillary and mandibular units, were fabricated. A wide variety of designs was observed for those not covered by the health insurance. 2. Approximately 83% of the 265 complete dentures were covered by the health insurance. The number of the maxillary units was slightly more than that of the mandibular units, which was similar to the data collected about 20 years ago. 3. Seven hundred and fifty-four partial dentures were placed and approximately 45% of these were covered by the health insurance. 4. Various designs were observed in the 'Konus-Kronen' type of prosthesis. They were assumed to be applied not only for the restoration of the edentulous areas, but also for the splinting of the remaining teeth. 5. Fixed bridges were placed in more than 90% of the cases with single tooth loss. However, partial dentures were more frequently used than the fixed bridges for the restoration of the two-tooth loss.
