The PANORAMIC FILM of 05/1991 shows a general delay of tooth development. For the moment, therefore, we do not speak of an aplasia of 15, 25 – although it seems obvious –, but rather of an extreme delay of development of 15, 25. This assumption is supported by the respective gross delay of development noticed in 35 and 37 . We may also speak of a delayed development of 35 compared to 45.
