右側上顎欠損患者に金属床顎義歯を用いて機能回復を図った一症例

抄録

A 78-year-old female patient underwent right-side maxillary resection. In 2005, during her initial treatment, a resin-base obturator prosthesis was delivered after preprosthetic treatment. In 2012, she came back to the clinic complaining of speech disability and discomfort due to thickness of the resin palatal plate. Because a clasp had broken, it was considered necessary to improve the stiffness of the obturator. A metal plate obturator prosthesis was fabricated for her dento-maxillary rehabilitation, and oral care was performed. The plaque control record （PCR） improved from 25.8％ before the dento-maxillary rehabilitation to 10％ currently through instruction by a dental hygienist. The metal plate obturator has demonstrated a good postoperative course for 5 years. In addition, the complaints of discomfort due to the prosthesis, speech disability and esthetic dissatisfaction have improved.
