Oswald was not fitted with a dental bridge. See the dental symbol for a dental bridge in the following chart. If he was fitted with a dental bridge then Oswald's dental chart would have shown a symbol identical or similar to what is depicted in this diagram.
Oswald's record has two chart's. The one on the left is for charting thing's that need fixing or might need fixing. It states right above that chart that the following are to be charted: "
Caries, Dental Disease, Missing Teeth, Abnormalities." There is no need -- or request -- for charting other things. Like existing fillings, crowns, and dental bridges.
The other chart on the form is for charting
Dental Treatments Accomplished.
Also the testimony which you have presented is very vague and therefore cannot be relied upon. The image of Oswald at school with the so called missing tooth is very grainy and also cannot be relied upon. As I have already stated the Harvey and Lee theory is a complete fabrication and pardon the pun is completely of the charts.
So forget about all that other CORROBORATING evidence if you want. That notation regarding the failed prosthesis on Oswald's chart is all that is needed to prove that the exhumed teeth don't match those of the Oswald in the Marines.
