The purpose of this controlled prospective study was to compare the satisfaction of patients rehabilitated with an immediately loaded implant-supported prosthesis and patients rehabilitated with a conventional denture in the mandible.
Selected mandibular partially or totally edentulous patients were included in this prospective study. Patients' mandibles were completely rehabilitated with immediately loaded implants supporting a screw-retained full-arch prosthesis (test group) or with a conventional denture (control group). The Satisfaction Profile (SAT-P), which investigates a number of psychologic aspects related to the function and esthetics of the stomatognathic apparatus, was administered to each patient 1 month before and 3 months after provisional prosthetic rehabilitation. The questionnaire comprised four different SAT-P items: quality of eating, eating behavior, mood, and self-confidence. A visual analog scale was used to elicit patient responses. SAT-P item scores were analyzed statistically by means of the Student t test and the chi-square test (or the Mann-Whitney nonparametric test), with P < .05 considered significant.
Forty-one patients were consecutively treated with 205 immediately loaded implants supporting a screw-retained full-arch prosthesis (test group); 38 patients were consecutively treated with a conventional denture (control group). Statistically significant differences were observed between the test and control groups for all four SAT-P items. The test group reported greater satisfaction for all items versus the control group. In both groups, the differences between pre- and postrehabilitation values were statistically significant.
Each patient was satisfied with their treatment outcomes, but patients who received an implant-supported prosthesis were more satisfied than the patients who received a conventional denture. The results suggest that a screw-retained full-arch prosthesis on immediately loaded implants is a predictable means of enhancing patient satisfaction.
本对照前瞻性研究的目的是比较即刻负重种植体支持修复体和常规义齿修复下颌骨的患者满意度。
选择下颌部分或完全无牙的患者参加本前瞻性研究。患者的下颌骨完全用即刻负重种植体修复，种植体支持螺丝固位的全口修复体（实验组）或常规义齿（对照组）。在临时修复体修复前 1 个月和修复后 3 个月，每位患者均接受满意度调查问卷（SAT-P），该问卷调查与咀嚼器官功能和美观相关的多个心理方面。问卷包括四个不同的 SAT-P 项目：进食质量、进食行为、情绪和自信心。使用视觉模拟量表来获取患者的反应。通过 Student t 检验和卡方检验（或曼-惠特尼非参数检验）对 SAT-P 项目评分进行统计学分析，P <.05 被认为具有统计学意义。
41 例患者连续接受 205 个即刻负重种植体支持螺丝固位的全口修复体（实验组）；38 例患者连续接受常规义齿（对照组）治疗。所有四个 SAT-P 项目在实验组和对照组之间均存在统计学显著差异。实验组在所有项目上的满意度均高于对照组。在两组中，治疗前后的差异均具有统计学意义。
每位患者对治疗结果都感到满意，但接受种植体支持修复体的患者比接受常规义齿的患者更满意。结果表明，即刻负重种植体支持螺丝固位的全口修复体是提高患者满意度的一种可预测方法。
