For the 2nd International Symposium on Ceramic, dentists were given a larger venue, while Geller and Mr. Makoto Yamamoto were given a smaller venue with 250 people. However, the audience grew so large that a new 250-person room was set up next door, but this was still not enough, so that the lecture was finally held in four 250-person rooms with a total capacity of 1,000 people. The lecture was so legendary that even though there was room for 1,000 people in the lecture room, there was still standing room only and some people could not get into the venue. Soon after this lecture, Mr. Makoto Yamamoto in the east and Willi Geller in the west gained the respect of dental professionals worldwide, and they would grow the field of cosmetic dentistry worldwide.
