The aim of this study was to examine the contribution of the palate to denture base support. Four subjects with tooth- or implant-supported maxillary overdentures were enrolled. Recordings (strain values converted to load values) were performed using miniature strain gauges and force transducers for the following conditions: metal framework only (A), denture base with full palatal coverage (B), and denture base without palatal coverage (C). The palatal-supporting ratio (PSR) was calculated using the equation PSR = (B - C) / A. The PSR values were less than 10% in all subjects, suggesting that the palate plays a minimal role in denture base support.
本研究的目的是检验腭部对义齿基托支持的贡献。招募了4名佩戴牙齿或种植体支持的上颌覆盖义齿的受试者。在以下条件下，使用微型应变片和力传感器进行记录（应变值转换为载荷值）：仅金属支架（A）、全腭覆盖的义齿基托（B）和无腭覆盖的义齿基托（C）。使用公式PSR = (B - C) / A计算腭部支持率（PSR）。所有受试者的PSR值均小于10%，这表明腭部在义齿基托支持中起的作用极小。
