1 94 J Meikai Dent Med 43 1, , A Case of Occlusal Discomfort Treated by Fixed Partial Denture Fabricated by Double-cast Technique Takafumi FUJITA 1, Tomoaki IIZUKA 1, Takuya HIROKAWA 1, Yu KAWADA 1, Ryohei YOSHIZAWA 2 and Masanori FUJISAWA 1 1 Division of Fixed Prosthodontics, Department of Restorative & Biomaterials Sciences, Meikai University School of Dentistry 2 Dental Laboratory, Meikai University Hospital Abstract : A case of a 75-year-old woman with occlusal discomfort is reported. She was referred by an oral surgeon with the complaints of occlusal discomfort and dysgeusia after treatment of fixed partial denture FPD in another dental clinic 2 years previously. As the treatment strategy, fabrication of new FPDs for the right and left sides of the mandible following reversible prosthodontic treatment including self-cure resin build-up was proposed. In the process of the FPD fabrication, a double-cast technique was adopted to ensure precise and favorable occlusion. With occlusal improvement, not only the occlusal discomfort but also the taste discomfort disappeared. A precise functional occlusal surface provides peripheral factors suitable for the intraoral environment, which may affect occlusal discomfort. Key words : occlusal dysesthesia, functional occlusal surface, double-cast technique 1
