To examine the current literature on the impact of patients' expectations on treatment outcomes or final patient satisfaction and to identify the theoretical frameworks, study designs and measurement instruments which have been employed to assess patients' expectations within implant dentistry.
A structured literature search of four databases Pubmed, Cochrane, Web of Science and PsychINFO was conducted following PRISMA guidelines. Any type of literature published in English discussing the topic of 'patients expectations' in oral health were identified and further screened. Studies reporting on expectations regarding dental implants were selected and a narrative review was conducted.
The initial search yielded 16707 studies, out of which 1051 'potentially effective studies' were further assessed and final 41 'effective studies' were included [Kappa = 0.76]. Ten observational studies, published from 1999 to 2013, dealt specifically with expectations of dental implants. There was a large degree of heterogeneity among studies in terms of assessment instruments. Expectations relating to aesthetics and function were primarily considered. Among the 10 studies, 8 were classified as quantitative research and 2 as qualitative research. The STROBE quality of reporting scores of the studies ranged from 13.5 to 18.0. Three of the 8 quantitative studies employed a before/after study design (prospective studies) and used visual analogue scales (VAS) to measure patient expectations.
There is a growing interest in patients' expectations of dental implants. Most studies are cross sectional in nature and the quality of reporting varies considerably. Expectations with respect to aesthetics and function are key attributes considered. The use of visual analogue scales (VAS) provides quantitative assessments of patients' expectations but the lack of standardization of measures prohibits meta- analyses.
审视当前关于患者期望对治疗结果或最终患者满意度影响的文献，并确定用于评估种植牙科患者期望的理论框架、研究设计和测量工具。
按照PRISMA指南，对四个数据库（PubMed、Cochrane、科学网和PsycINFO）进行结构化文献检索。识别并进一步筛选以英文发表的、讨论口腔健康中“患者期望”主题的任何类型文献。选择报告种植牙期望的研究并进行叙述性综述。
初步检索得到16707项研究，其中1051项“潜在有效研究”被进一步评估，最终纳入41项“有效研究”[卡帕值=0.76]。1999年至2013年发表的10项观察性研究专门涉及种植牙期望。研究在评估工具方面存在很大程度的异质性。主要考虑了与美学和功能相关的期望。在这10项研究中，8项被归类为定量研究，2项为定性研究。这些研究的STROBE报告质量得分在13.5至18.0之间。8项定量研究中的3项采用前后研究设计（前瞻性研究），并使用视觉模拟量表（VAS）来测量患者期望。
对患者种植牙期望的兴趣日益浓厚。大多数研究本质上是横断面研究，报告质量差异很大。美学和功能方面的期望是关键属性。视觉模拟量表（VAS）的使用提供了对患者期望的定量评估，但测量缺乏标准化阻碍了荟萃分析。
