Erika Colebank traveled to Tokyo Japan to take an intensive certification course in a lower suction denture technique. This technique has been developed by Dr. Jiro Abe in Sengawa Tokyo. It involves two special impressions, bite registration, and denture finishing. These lower dentures look incredibly different than the conventional lower dentures we have been taught to build. 80% of complete lower denture patients can attain suction; an examination is performed to see who are candidates for suction lower dentures.
