He had lost one upper central and damaged the adjacent lateral about 3 years earlier. The other central was chipped at the MI corner but otherwise sound. He attended having already had a spring cantilever bridge made 2-3 years before. My typed notes state that the original slice preps for the 3/4 GC retainers were too short and so provided inadequate mechanical retention.
Apart from possibly the cast gold post/core for the post crown (Little or no ferrule possible!), the rest of the casting and the PJCs were made by the Dental School Lab techs.
Even in B&W we can see the shade match wasn't great. The images were taken on a day that the bridge was cemented with a temporary Zinc Oxide Eugenol + Vaseline temporary cement.
Also note the state of the gingival tissues at the lateral incisor crown. I believe that TC had been in place for about a month and no doubt had faulty margins which caused gingival irritation and I almost certainly had just cauterised the bleeding tissue with a heated burnisher.
Rem these scanned images are from B&W prints which are 40-odd years old, taken with my newly acquired 35mm Pentax camera with 135 mm Telephoto lens + extension tubes and an attached hot-shoe flash gun too.
The die for the lateral incisor would have been copper plated.
It is also worth noting that due to the high gold costs, students in that year were not permitted to undertake any bridgework unless it was part of an approved elective study - which it was together with some work on precision attachments!
