The aim of this study was to validate the reproducibility and observer variability of the Functional Implant Prosthodontic Score (FIPS), while considering the level of dental experience for intra- and inter-examiner analysis.
A total of 44 examiners (n = 31 undergraduate dental students and n = 13 postgraduate prosthodontic students) applied FIPS to ten sample cases each showing one implant-supported single crown for premolar or molar replacements. Examiners' assessments were carried out twice at an interval of 2 weeks (round A and round B). Pearson's correlations including 95% confidence intervals (CI95) were calculated for intra- and inter-examiner reproducibility testing. Cohen's Kappa score was additionally used to analyze the homogeneity of each FIPS variable.
The mean values of the total FIPS scores for round A (7.21 ± 0.91) and round B (7.27 ± 0.86) showed a strong correlation of 0.9374 (CI95 0.9250; 0.9478). No significant difference was identified between undergraduates and postgraduates representing different levels of dental experience. Homogeneity analysis of the defined FIPS variables was not significantly different.
Both intra- and inter-examiner analysis revealed very congruent results for reproducibility testing of FIPS. The findings validated the potential of FIPS as an objective and reliable evaluation instrument in assessing fixed implant restorations in posterior sites independent of the level of dental experience.
FIPS can be considered as an additional diagnostic tool to classify fixed implant restorations in routine dental practice, to compare follow-up observations, and to identify potential risks of failure.
本研究旨在验证功能性植入修复体评分（FIPS）的可重复性和观察者变异性，同时考虑到不同牙科经验水平的内部和外部检查分析。
共有 44 名检查者（n=31 名本科牙科学生和 n=13 名研究生修复学生）对每个案例各进行了 10 次 FIPS 评估，这些案例均为展示用于前磨牙或磨牙替代的单颗种植体支持的单冠。检查者的评估在 2 周的间隔内进行了两次（A 轮和 B 轮）。计算了内部和外部检查者重复性测试的 Pearson 相关系数（包括 95%置信区间[CI95]）。还使用 Cohen's Kappa 评分来分析每个 FIPS 变量的均匀性。
A 轮（7.21±0.91）和 B 轮（7.27±0.86）的总 FIPS 评分平均值显示出高度相关，为 0.9374（CI95 0.9250；0.9478）。代表不同牙科经验水平的本科生和研究生之间没有发现显著差异。定义的 FIPS 变量的均匀性分析没有显著差异。
内部和外部检查者分析都为 FIPS 的可重复性测试提供了非常一致的结果。这些发现验证了 FIPS 作为一种客观、可靠的评估工具的潜力，可用于评估后牙区固定种植体修复体，而与牙科经验水平无关。
FIPS 可以被视为一种额外的诊断工具，用于在常规牙科实践中对固定种植体修复体进行分类，比较随访观察，并识别潜在的失败风险。
