To evaluate oral health related quality of life (OHQoL) in edentulous patients treated with immediately loaded implants in the maxilla.
Fifty-one edentulous patients in two centers received six maxillary implants each were loaded within 24 h with provisional restoration. Definitive restoration was delivered 20-24 weeks later. OHQoL was evaluated preoperatively with the Oral Health Impact Profile 49 questionnaire (OHIP-49) and on five subsequent occasions. OHIP-49 includes seven domains representing functional limitation, physical pain, psychological discomfort, physical disability, psychological disability, social disability, and handicap. A reduction in OHIP scores indicated an improved OHQoL.
Forty-five patients reached the three-year follow up. OHQoL improved after treatment. A plateau of OHQoL improvement was observed at 12 months after surgery. The seven domains improved at different pace, 12 weeks to 12 months after treatment. OHIP showed continuously low scores with no significant changes at consecutive visits 12 months to three years after treatment. Dental status with removable prosthesis in the mandible had a negative impact on OHQoL prior to and during treatment, but did not affect OHQoL after permanent restoration was placed. Patients age or gender did not affect OHQoL.
Patients with edentulous maxilla who received prosthetic rehabilitation on immediately loaded implants experienced the highest improved OHQoL 12 months after implant installation. Quality of life related to oral health continued to be high after three years. Edentulous patients with atrophy of the maxilla experience an improved OHQoL after implant treatment with immediate loading protocol.

评估上颌即刻负重种植体修复的无牙颌患者的口腔健康相关生活质量（OHQoL）。
两个中心的 51 名无牙颌患者每侧上颌各植入 6 枚种植体，24 小时内用临时修复体负重。20-24 周后进行最终修复。术前使用口腔健康影响简表 49 问卷（OHIP-49）和随后的 5 次评估 OHQoL。OHIP-49 包括代表功能受限、身体疼痛、心理不适、身体残疾、心理残疾、社会残疾和障碍的 7 个领域。OHIP 评分的降低表明 OHQoL 得到了改善。
45 例患者达到 3 年随访。治疗后 OHQoL 得到改善。术后 12 个月观察到 OHQoL 改善的平台期。7 个领域在治疗后 12 周至 12 个月之间以不同的速度改善。OHIP 在治疗后 12 个月至 3 年内连续就诊时表现出持续较低的评分且无显著变化。下颌有可摘义齿的牙齿状况在治疗前和治疗期间对 OHQoL 有负面影响，但对永久修复体放置后的 OHQoL 没有影响。患者年龄或性别对 OHQoL 没有影响。
上颌无牙颌患者接受即刻负重种植体修复后，在种植体植入后 12 个月体验到最高的 OHQoL 改善。3 年后，与口腔健康相关的生活质量持续较高。上颌萎缩的无牙颌患者接受即刻加载方案的种植治疗后，OHQoL 得到改善。
