The aim of this study was to identify factors influencing edentulous patients' preferences for treatment using conventional or implant dentures (ID). A consecutive sample of 112 patients was selected in a university facility. All patients responded to a questionnaire concerning preferences about treatment and factors influencing preferences for conventional complete dentures (CD), implant-retained overdentures (IRO) and fixed implant-supported prostheses (FISP). Subsequently, a set of 21 questions was presented, and patients were requested to rate the importance of various potential reasons influencing their choice of treatment. Preference for CD was more prevalent for maxilla (52·7%) and mandible (41·1%). Fixed implant-supported prostheses and IRO were preferred for the mandible (FISP=37·5%; IRO=21·4%) rather than maxilla (FISP=27·7%; IRO=19·6%). The most preferred treatment option among the subjects when evaluating both arches was the implant-supported fixed or removable prosthesis (FISP/IRO). A preference for combined upper and lower CD was also commonly reported (39·3%). Factor analysis identified six components that accounted for 72·2% of the total variance: (i) psychosocial benefits, (ii) functional performance, (iii) technical and financial concerns, (iv) post-insertion complaints, (v) removability and (vi) longevity. Technical and financial concerns (cost, complexity, surgery risks and duration of treatment) were more relevant for those who preferred ID (P<0·001). With the exception of post-insertion complaints, all mean scores of component factor loadings were positive for ID. Conventional complete dentures are associated with lower expected outcomes by patients, and cost-related issues are the major factors associated with the preferences for implant treatment of edentulous patients.
本研究旨在确定影响无牙颌患者对常规或种植义齿（ID）治疗选择的因素。在一所大学附属医院选择了连续样本 112 名患者。所有患者均对有关常规全口义齿（CD）、种植体支持覆盖义齿（IRO）和固定种植体支持修复体（FISP）治疗偏好以及影响偏好因素的问卷做出回答。随后，提出了一组 21 个问题，要求患者对影响治疗选择的各种潜在原因的重要性进行评分。上颌（52.7%）和下颌（41.1%）更倾向于选择 CD。下颌（FISP=37.5%；IRO=21.4%）而非上颌（FISP=27.7%；IRO=19.6%）更倾向于选择固定种植体支持修复体和 IRO。在评估上下颌时，受试者最偏好的治疗方案是种植体支持的固定或可摘义齿（FISP/IRO）。同时，也常报告有上下颌联合 CD 的偏好（39.3%）。因子分析确定了六个占总方差 72.2%的组成部分：（i）心理社会获益，（ii）功能表现，（iii）技术和经济考虑，（iv）植入后抱怨，（v）可摘性和（vi）耐用性。技术和经济方面的考虑（成本、复杂性、手术风险和治疗持续时间）对那些更喜欢 ID 的人更为重要（P<0·001）。除植入后抱怨外，所有 ID 组成部分因子负荷的平均值均为正值。患者对常规全口义齿的预期结果较低，与成本相关的问题是与无牙颌患者选择种植治疗偏好相关的主要因素。
