ObjectivesThis回顾性研究旨在评估早期和晚期种植体丢失率transscrestal窦底提升（TSFE）后，并确定与这些failure.Material和MethodsAll患者TSFE治疗，同时种植体放置在2015年10月至2019年3月进行了评估纳入。共有802例患者（976个种植体）符合入选标准。从病历和图像软件中收集临床和影像学信息。进行单变量和多变量考克斯比例风险脆弱性回归模型，以确定与TSFE后早期和晚期种植体丢失相关的潜在风险因素。结果3年累积种植体存活率为96.9%（95%CI 95.8%-98.0%）。12例患者的12颗种植体在基台连接前或连接时丢失，24例患者的24颗种植体在功能加载后丢失。考克斯脆弱性回归分析表明，两个因素与早期种植体丢失相关：使用移植材料的TSFE和临床经验较少的术者。至于晚期种植体丢失，RBH ≤6 mm，男性，和某些种植体品牌与一个显着增加的failurerate. ConclusionsTransscrestal窦底提升，同时种植体放置是一个可预测的治疗选择萎缩上颌骨。移植材料的存在和外科医生临床经验的缺乏可能与早期种植体丢失相关，而低RBH、男性和某些种植体品牌往往会增加晚期种植体丢失。
ObjectivesThis retrospective study aimed to evaluate early and late implant loss rates after transcrestal sinus floor elevation (TSFE) and to identify the risk factors related to these failures.Material and MethodsAll patients treated with TSFE and simultaneous implant placement during October 2015 to March 2019 were evaluated for inclusion. A total of 802 patients with 976 implants met the inclusion criteria. Clinical and radiographic information was collected from medical records and image software. Univariate and multivariate Cox proportional hazards frailty regression models were performed to identify potential risk factors associated with early and late implant loss after TSFE.ResultsThe 3‐year cumulative implant survival rate was 96.9% (95% CI 95.8%–98.0%). Twelve implants in 12 patients were lost before or at the abutment connection, while 24 implants in 24 patients were lost after functional loading. The Cox frailty regression analyses indicated that two factors were correlated with early implant loss: TSFE with grafting materials, and operators with less clinical experience. As for late implant loss, RBH ≤6 mm, male sex, and certain implant brands were associated with a significantly increased failure rate.ConclusionsTranscrestal sinus floor elevation with simultaneous implant placement is a predictable treatment option in the atrophic maxilla. The presence of grafting materials and the lack of clinical experience of the surgeon were possibly associated with early implant loss, while low RBH, male sex, and certain implant brands tended to increase late implant loss.
