To compare the patient-reported effect of treatment with implant-supported fixed prosthesis (ISFP) and fixed dental prosthesis (FDP) in patients with a small number of tooth losses to replace.
From a population of 155 patients receiving either ISFP or FDP, 68 patients were matched in pairs based on gender, number of teeth replaced, zone of replacement, age and number of remaining teeth. The patient-reported effect was prospectively obtained by measuring change in the short-form oral health impact (OHIP-14) from before to one month after treatment. Effect size (ES), standardised response mean (SRM) and a minimal important difference of two units were applied to estimate the magnitude of the change.
Both the ISFP and FDP groups decreased significantly in OHIP-14 after treatment (P < .01). The change was not significantly different between the ISFP and FDP groups. The magnitude of the change was for both treatments moderate and slightly higher in the ISFP group (ES = 0.52 and SRM = 0.58) than in the FDP group (ES = 0.48 and SRM = 0.47). Applying the minimal important difference showed that 23 participants in the ISFP group and 21 in the FDP group had good effect.
The patient-reported effect of treatment with ISFP or FDP was similar, clinically meaningful and of moderate magnitude in patients with a small number tooth losses to replace.
比较少量缺牙患者接受种植体支持固定修复体（ISFP）和固定义齿（FDP）治疗的患者报告的治疗效果。
从接受 ISFP 或 FDP 治疗的 155 名患者中，根据性别、缺牙数量、置换区、年龄和剩余牙齿数量，将 68 名患者配对。通过测量治疗前一个月的短期口腔健康影响（OHIP-14）的变化，前瞻性获得患者报告的效果。应用效应大小（ES）、标准化反应均值（SRM）和 2 个单位的最小重要差异来估计变化的幅度。
ISFP 和 FDP 组在治疗后 OHIP-14 均显著降低（P<.01）。两组之间的变化无显著差异。对于两种治疗方法，ISFP 组的变化幅度较大且稍高（ES=0.52，SRM=0.58），而 FDP 组的变化幅度较小（ES=0.48，SRM=0.47）。应用最小重要差异显示，ISFP 组有 23 名患者和 FDP 组有 21 名患者的治疗效果良好。
在少量缺牙患者中，ISFP 或 FDP 治疗的患者报告的治疗效果相似，具有临床意义且变化幅度适中。
