To assess implant stability and safety of loading a bone-anchored implant 1 week after surgery. The patients were loaded at 1 week for fast rehabilitation and ease of logistics.
Single center, prospective cohort study of 25 adults with expected normal skin and bone quality.
Implantation of the Baha BA400 implant system using a linear incision technique without skin thinning. Abutment lengths of 8, 10, and 12 mm were used.
Implant stability quotient (ISQ) 0, 7, 14, 30 days and 3, 6, and 12 months postoperatively.
Twenty-five patients were included, 23 could be followed up for 1 year. Mean ISQ was increasing throughout the observation period with no sign of adverse influence from the early loading. No implants were lost or clinically unstable. Individual ISQ curves fall in two categories-continually increasing ISQ or increasing ISQ with initial dip. ISQ for patients in the initial dip group eventually increased despite the early and continued loading.
Loading of the implant system under study 1 week after surgery have been successful for 25 patients with expected normal bone quality followed up for 1 year. No implants were lost. All individual ISQ were increasing throughout the study period. The early loading of the implant under study does not seem to influence the osseointegration.
评估术后1周加载骨锚式种植体的种植体稳定性和安全性。患者在1周时进行加载，以实现快速康复并简化后勤工作。
对25名预期皮肤和骨质正常的成年人进行单中心前瞻性队列研究。
采用线性切口技术且不进行皮肤减薄，植入Baha BA400种植体系统。使用8、10和12毫米的基台长度。
术后0、7、14、30天以及3、6和12个月时的种植体稳定性商数（ISQ）。
纳入25名患者，其中23名可随访1年。在整个观察期内，平均ISQ持续增加，未显示早期加载有不良影响的迹象。没有种植体丢失或出现临床不稳定情况。个体ISQ曲线分为两类——ISQ持续增加或ISQ先下降后增加。尽管早期和持续加载，但初始下降组患者的ISQ最终仍有所增加。
对于25名预期骨质正常的患者，术后1周加载本研究中的种植体系统并随访1年取得成功。没有种植体丢失。在整个研究期间，所有个体的ISQ均在增加。本研究中种植体的早期加载似乎不影响骨整合。
