Titanium (Ti) is a relatively new metal in prosthodontics. As a possible material for removable partial dentures (RPDs), it was used in its pure form to make 10 RPDs which were compared with 10 identical cobalt-chromium (Co-Cr) alloy RPDs in a clinical trial. The dentures were used alternately for four weeks, the subjects were asked to answer a questionnaire and then the Co-Cr dentures were withdrawn. The Ti dentures were then followed up for 2 years and another standardized questionnaire administered. A survival rate of rests and retainers of 91% was recorded and the dentures were found to be more comfortable (55%) and preferred (64%) than the Co-Cr dentures. Factors to increase the success rates are discussed.
钛（Ti）是口腔修复学中一种相对较新的金属。作为可摘局部义齿（RPD）的一种可能材料，其纯形式被用于制作10副RPD，并在一项临床试验中与10副相同的钴铬（Co-Cr）合金RPD进行比较。这些义齿交替使用四周，受试者被要求回答一份问卷，然后撤回Co-Cr义齿。然后对Ti义齿进行2年的随访，并发放另一份标准化问卷。记录到支托和固位体的生存率为91%，并且发现这些义齿比Co-Cr义齿更舒适（55%）且更受青睐（64%）。文中讨论了提高成功率的因素。
