OBJECTIVE To incorporate a metal framework into removable partial dentures, the dimensional accuracy of thermoplastic resins requires precision equivalent to conventional acrylic resins. This study aimed to evaluate the fitting accuracy of thermoplastic resins compared to heat-cured acrylic resin. MATERIALS AND METHODS Four thermoplastic resins(More)
PURPOSE The purpose of this study was to investigate the influence of the major connector in a maxillary denture. METHODS Eight patients with sound dentition were recruited in this study. The experimental connectors were fabricated with Co-Cr. Two positional designs were used: one was the middle type (M), and the other was the anterior and posterior type(More)
OBJECTIVE To investigate the effects of the width and cross-sectional shape of the major connectors of maxillary dentures located in the middle area of the palate on the accuracy of phonetic output of consonants using an originally developed speech recognition system. PATIENTS AND METHODS Nine adults (4 males and 5 females, aged 24-26 years) with sound(More)
Using the Nash product (Nash Social Welfare Function) as a micro foundation, we create a decomposable index to evaluate the unfairness of representation in electoral districts. Using this index, we decompose the factors of such unfairness into apportionment and districting. We explore the situations of New Zealand, the United States, Australia, the United(More)
OBJECTIVES The purpose was to assess the early effects of removable partial denture (RPD) placement on abutment teeth in patients with periodontal disease. METHODS Fifteen distal-extension RPDs and 19 abutment teeth were evaluated in 13 patients with moderate-to-severe periodontal diseases. Clinical periodontal records and grey level (GL) score based on(More)
Although the demand for aesthetic restoration of primary molars has increased, the full-crown restorations using resin and the details of the wear characteristics of trimethylolpropane trimethacrylate (TMPT) filler containing resins for primary molars are not well understood. This study was conducted to determine whether new light-cured composite resin(More)
