作者运用电阻应变传感技术,结合单片机数据处理及打印系统,研制成功了修复体固位力测试仪。其可在口腔中直接准确地测定修复体的实际固位力,首次建立了在口腔中实际测量修复体固位力的方法,为定量研究修复体固位提供了手段。本文还介绍了该仪器在测定磁性固位总义齿固位力中的应用。 The author uses resistance strain sensing technology, combined with single-chip data processing and printing systems, the successful development of the prosthesis retention force tester. It can directly and accurately measure the actual retention force of the prosthesis in the oral cavity, and for the first time establishes the method of actually measuring the retention force of the prosthesis in the oral cavity, which provides a means for quantitatively studying the retention of the prosthesis. This article also introduces the application of this instrument in determining the retentive force of magnetic retention denture.
