We investigated the hardening characteristics of impression materials for impression making of flabby tissue and the impression methods of flabby tissue using custom trays. And we applied the results to the patients having the maxillary edentulous ridge with flabby tissue.And, when only prosthodontic treatment was not enough to recover the oral function of those patients, we applied the method for reconstructing the maxillary edentulous ridges with flabby tissue by application of hydroxyapatite granules (flabby ridge reconstruction method FRR method) to them, and obtained the good courses. However, after applying the FRR method, the flabby tissue had rarely disappeared but almost remained and been removed.No apparatus was suitable to examine the above-mentioned properties of flabby tissue, and the palpation only was depended. The purpose of this study was to develop an apparatus which evaluate objectively the flabby tissue and evaluate the usefulness.The trial diagnostic apparatus for flabby tissue was composed of the measuring part with the continuous percussible device and the instrument measuring the displacements and the analyzing part for observing and analyzing waves.The models with the flabby tissue simulated the different conditions of bone support and real flabby tissue of patients were measured using this apparatus. We evaluated them by the maximum amplitude and decrement time of observed waves.The trial diagnostic apparatus for flabby tissue could distinguish 27 simulation models and be applied to patients. in the future, we must collect more clinical data with this apparatus and improve the complicated apparatus.

本文研究了松弛组织印模材料的硬化特性和使用定制托盘进行松弛组织印模的方法。并将其应用于上颌无牙颌牙槽嵴松弛的患者，当单纯修复治疗不足以恢复患者的口腔功能时，应用羟基磷灰石颗粒重建上颌无牙颌牙槽嵴松弛的方法（松弛牙槽嵴重建法FRR法），取得了良好的效果。但应用FRR法后，松弛组织很少消失，几乎全部残留或被去除，没有适合于检查松弛组织上述性质的仪器，只能依靠触诊。为了研制一种能客观评价松弛组织的仪器，并对其实用性进行评价。松弛组织试验诊断仪由连续位移测量装置和位移测量仪组成的测量部分和波形观察分析部分组成。松弛组织模型模拟了不同的骨支持条件和真实的松弛组织，并对松弛组织进行了分析。松弛组织试验诊断仪的主要功能是测量松弛组织的强度，测量松弛组织的强度，测量松弛组织的强度使用该装置测量患者。通过观察波形的最大振幅和衰减时间进行评价，该松弛组织试验诊断仪可区分27个仿真模型，并可用于患者。今后还需进一步收集临床资料，并对复杂的仪器进行改进。
