To clarify the maintenance plan for partially edentulous patients reconstructed their occlusion in prosthodontic treatment, clinical observation for effect of denture cleanser and denture surface smoother, development of new relining material and the measuring error of denture frame work of titanium alloy by one-piece cast method were investigated.1. Observation on the effect of denture cleanser and denture surface smoother on denture plaque control1) Denture plaque is deposited within a few hours. The area of attached plaque shows individial difference, regional difference and difference by foods. Within 8 hours after denture insertion, plaque had covered 43% of the buccal surface of upper molar region.2) The denture cleanser available on the market cleaned well. 20minite's cleansing with them removed between 80% to 90% of the denture plaque.3) When denture smoother was used, 8 hours after wearing of denture, denture plaque deposit area accounted for 30% of the buccal polished surface … More in the upper molar region.4) When denture surface smoother was used, pratically all plaque was removed from the denture surface about 10 minites immmersion in most of denture cleanser.5) When denture surface was used to aged patients, less denture deposit and more easy to clean their denture obserbed than when no smoother was used.2. Development of new relining material1) Relining for the denture base improves denture fitness, however, usual material of the relining makes much irritation and bad taste during preparation. Therefore, a new no-irritation relining material for direct relining method is developed.2) There are many cases difficult to prepare the complaint of pain caused by thin underlying tissues. For these patients, it is needed to seat a resilient material between basal surface and soft tissue. Therefore, a new resilient relining material for direct relining method is developed.3. Measuring error on denture frame work of Titanium alloyMeasuring error on denture frame work of Titanium alloy by one-piece cast method were investigated. When the frame work was prepared to Titanium alloy by one-piece cast mehod, a little more expansion showed in inter-abutment distance compaired with original dimensions than when it was prepared to Co-Cr alloy by one-piece cast method. Then, it is necessary to improve the measuring error on Titanium cast framework. Less

为明确部分无牙颌患者在修复治疗中重建咬合的维护方案，对义齿清洁剂和义齿表面光滑剂的使用效果、新型补衬材料的研制以及钛合金义齿支架整体铸造法的测量误差进行了临床观察.义齿清洁剂和义齿表面光滑剂控制牙菌斑的效果观察1）牙菌斑在数小时内沉积。附着菌斑面积存在个体差异、地区差异和食物差异。2）市售义齿清洁剂清洁效果良好。3）使用义齿光滑剂时，戴用义齿8 h后，义齿菌斑存款面积占颊面抛光面积的30 ...更多信息 结论：1.使用义齿表面光滑剂时，在大多数义齿清洁剂浸泡10 min左右，牙菌斑几乎全部从义齿表面清除; 5.老年患者使用义齿表面光滑剂时，义齿存款较少，义齿基托易于清洁。新型衬层材料的开发1）义齿基托衬层可提高义齿适合性，但常用的衬层材料在制备过程中会产生刺激性和不良口感。因此，开发了一种新的无刺激性的直接换衬方法的换衬材料。2）有许多情况下，难以准备的投诉所造成的疼痛薄的底层组织。对于这些患者，需要在基底表面和软组织之间放置弹性材料。为此，研制了一种用于直接换衬法的新型回弹换衬材料.钛合金义齿支架的测量误差研究了钛合金义齿支架整体铸造法的测量误差。采用钛合金整体铸造法制备的支架，其基牙间距与原始尺寸相比，比采用钴铬合金整体铸造法制备的支架有略微的膨胀。因此，有必要对钛合金铸造框架的测量误差进行改进。少
