Regions of inflammation with or without ulceration beneath removable partial dentures have been of concern to prosthodontists for many years. The etiology of these lesions has not been established, but potential factors are microbial infection, obstructive sialadenitis, and allergic-type reactions to the metal framework. A new etiological factor that may be involved is described. Focal pitting corrosion and by-products of corrosion in nickel-chromium alloys are discussed as toxic agents responsible for palatal lesions. Six patient reports that include results of tissue biopsy and EDAX analysis of casting are presented.
可摘局部义齿下方出现炎症区域（伴或不伴溃疡）多年来一直是口腔修复医生关注的问题。这些病变的病因尚未明确，但潜在因素包括微生物感染、阻塞性涎腺炎以及对金属支架的过敏型反应。本文描述了一个可能涉及的新病因。文中讨论了镍铬合金中的局部点蚀和腐蚀副产物作为导致腭部病变的有毒物质。本文还呈现了6例患者报告，包括组织活检结果和铸件的能谱分析结果。
