Statistical analysis of the fabrication of fixed and removable partial dentures (in 2002)

A statistical survey based on laboratory records was performed on the number of fixed partial dentures and removable partial dentures fabricated at the dental hospital of Tokyo Medical and Dental University from April 1 to September 30, 2002. A comparison was also performed with a previous survey that had been carried out in 1997 to detect any change and possible alternations in the near future. From the findings of this statistical survey, the conclusions were as follows: 1. A total of 2,656 fixed and removable partial dentures were fabricated during the six-month period in 2002. 2. The 3-unit fixed partial denture was most common (64.0%), and the number of fixed partial dentures decreased as the number of units increased. 3. For a single missing tooth, a fixed partial denture was more popular (80.8%) than a removable partial denture. 4. For two missing teeth, there was little difference between the number of fixed and removable partial dentures. In the anterior region, fixed partial denture was more common, while in contrast, in the posterior region, removable partial denture was more common.
