During recent years a new treatment concept, Brånemark Novum, has been developed in which implants are inserted in the edentulous lower jaw and immediately connected to a prefabricated titanium bar. A fixed prosthesis is then attached to the bar during or immediately following surgery.
The aim of the present study was to investigate the application of this concept under various settings, to determine technique sensitivity, and to evaluate the clinical outcome after 1 year of follow-up.
Fifty-one patients were included in a prospective multicenter investigation and followed up for 1 year. Cumulative implant survival rates were evaluated by life table analysis. In addition, clinical comparisons were performed to evaluate implant loss in relation to patient characteristics. Questionnaires were used to evaluate the treatment protocols and to obtain patients' opinions.
The prosthetic treatment was completed on the same or the following day in 76% of the patients. The cumulative implant survival rates for implants and prostheses were 91% and 94%, respectively, after 12 months.
The present study demonstrated that single-stage surgery and immediate loading of implants with prefabricated bridgework in the mandible can result in high implant success and significant reduction in treatment time, with patient satisfaction.
近年来，一种新的治疗理念——“诺贝尔种植牙新方法（Brånemark Novum）”得以发展，即在无牙的下颌骨中植入种植体，并立即将其与预制钛杆相连。然后在手术过程中或手术后立即将固定义齿连接到钛杆上。
本研究的目的是在各种情况下研究这一理念的应用，确定技术敏感性，并在随访1年后评估临床结果。
51例患者纳入一项前瞻性多中心研究，并随访1年。通过寿命表分析评估种植体的累积存活率。此外，进行临床比较以评估与患者特征相关的种植体丢失情况。采用问卷调查来评估治疗方案并获取患者的意见。
76%的患者在同一天或次日完成了修复治疗。12个月后，种植体和义齿的累积存活率分别为91%和94%。
本研究表明，在下颌骨中进行单阶段手术并立即用预制桥体加载种植体，可获得较高的种植成功率，显著缩短治疗时间，并提高患者满意度。
