Abstract:

Objective To explore the oral health management dilemmas of chronic periodontitis patients with implant dentures，so as to provide a reference for formulating scientific and effective oral nursing intervention programs. Methods Based on the information-motivation-behavioral skills model（IMB），the interview outline was formulated. Using the purposive sampling method，patients with chronic periodontitis who underwent implant restoration in a tertiary A stomatological hospital in Taiyuan City，Shanxi Province from April to June 2024 were selected for semi-structured interviews. The data were analyzed by means of directed content analysis. Results A total of 3 core themes were extracted，covering 10 sub-themes，namely knowledge deficiency and information dilemma（lack of oral health-related knowledge，cognitive misunderstanding and memory deviation，difficulty in identifying miscellaneous information），coexistence of emphasis and avoidance（perceived benefits of oral health management，positive feedback reinforcing internal motivation，avoidance induced by psychological burden，the duality of diverse social networks），behavioral skills transformation difficulties（difficulties in home maintenance practice，insufficient professional guidance and support，and uneven self-efficacy）. ConclusionThe oral health management behavior of chronic periodontitis patients with implant dentures is affected by many factors. We should aim to develop innovative oral health services based on Internet，bridge the cognitive misunderstanding and memory bias of patients，stimulate the internal driving machine of oral health behavior，strengthen the external support of multiple social networks，refine the teaching model of oral health management，and empower oral health self-management.

摘要：

目的 探析慢性牙周炎种植义齿患者的口腔健康管理困境，为制订科学有效的口腔护理干预方案提供参考。 方法 基于信息-动机-行为技巧（information-motivation-behavioral skills，IMB）模型制订访谈提纲，采用立意抽样法，选取2024年4月—6月在山西省太原市某三级甲等口腔医院就诊的20例慢性牙周炎种植修复后患者进行半结构式访谈，使用定向内容分析法分析资料。 结果 共凝炼出3个核心主题，涵盖10个亚主题：知识缺陷与信息困境（口腔健康相关知识匮乏、认知误区与记忆偏差、信息冗杂甄别困难）；重视与逃避并存（感知口腔健康管理获益、正向反馈强化内部动机、心理负担诱发就医逃避、多元社会网络的两面性）；行为技巧转化困境（居家维护实操困难、专业指导支持不足、自我效能参差不齐）。 结论 慢性牙周炎种植义齿患者的口腔健康管理行为受诸多因素影响，应有的放矢发展基于互联网的口腔健康管理创新服务，弥合患者的认知误区和记忆偏差，激发健康行为内驱动机的同时强化多元社会网络的外部支持，细化口腔健康管理教授模式，赋能口腔健康自我管理。
