目的头颈癌患者假体康复中假体成功的定义尚不明确。材料与方法本前瞻性观察研究纳入52例患者，共植入309颗种植体。在患者和种植体特异性变量的影响下，评估2年随访时种植体存活（原位和负载）和种植体成功（修改Albrektsson标准）。结果39例患者共种植了234颗种植体。2年后种植体总体存活率为92.3%(216/234)，骨整合率为94%（220/234）。种植成功率为78.6%（184/234）。失败的主要原因是“骨吸收> 1.7mm”（n = 27, 11.5%）和“种植体未原位或未加载”（n = 18, 7.7%）。吸烟（OR 3.1,p = 0.034）、骨移植（OR 2.4,p = 0.021）和辐射剂量bbb60 Gy （OR 3.8,p = 0.025）是种植体失败的重要预测因素。结论头颈部肿瘤患者种植体存活与种植体成功有显著差异。种植体的成功与否主要取决于种植体周围的骨吸收。
Objectives Definition of implant success is unclear in prosthetic implant-based rehabilitation of head neck cancer patients. Materials and methods Fifty-two patients with 309 inserted implants were included in this prospective observational study. Implant survival (in situ and loaded) and implant success (modified Albrektsson criteria) at 2-year follow-up were evaluated under the influence of patient- and implant-specific variables. Results Thirty-nine patients with 234 implants finished the study. Overall implant survival after 2 years was 92.3% (216/234) with an osseointegration rate of 94% (220/234). Implant success was 78.6% (184/234). Main reasons for failure were "bone resorption > 1.7mm" (n = 27, 11.5%) and "implant not in situ or not loaded" (n = 18, 7.7%). Smoking (OR 3.1,p = 0.034), bone grafts (OR 2.4,p = 0.021) and radiation dose > 60 Gy (OR 3.8,p = 0.025) revealed as significant predictors for implant failure. Conclusion Implant survival differs significantly from implant success in head and neck cancer patients. Implant success is mainly determined by radiographic peri-implant bone resorption.
