本研究的目的是比较全口义齿有无腭部全覆盖的应变，并确定加固的效果。制作了三种类型的上颌全口义齿（有腭、无腭和无腭但有加强件），加强件由钴铬合金制成。将应变片连接到抛光表面，并在第一前磨牙和第一磨牙区域施加垂直载荷。对菌株进行统计学比较。最大应变发生在腭前表面，在有腭覆盖的义齿中为拉伸，在无腭覆盖的义齿中为压缩。有加固的义齿比没有加固的义齿发生的应变明显更少。
The purpose of this study was to compare the strain of complete dentures with and without full palatal coverage and to determine the effect of reinforcement. Three types of maxillary complete dentures (with palate, without palate, and without palate but with reinforcement) were fabricated, and reinforcements were made from a cobaltchromium alloy. Strain gauges were attached to the polished surface, and a vertical load was applied in the region of the first premolar and first molar. The strains were statistically compared. The greatest strain occurred on the anterior palatal surface and was tensile in the denture with palatal coverage and compressive in the denture without palatal coverage. Significantly less strain occurred in dentures with reinforcement than without reinforcement.
