Paper Abstract

35mm photography of denture teeth and resin replicas through a convergent-axes microscope was used in an assessment of wear in dental restoration materials. The difficulty was to isolate and evaluate the significant photogrammetric parameters, but thereafter, the required depths could be calculated to accuracies of 0.01 mm r.m.s. using stereocomparator observations and quite simple formulae. The technique is applicable to biomedical laboratories which have access to an appropriate microscope if photogrammetric observations can be undertaken.
