The aim of the present study was to compare the treatment outcome of TiUnite- and turned-surfaced Brånemark System (Nobel Biocare AB, Göteborg, Sweden) implants when applying immediate loading of cross-arch designed fixed partial dentures in the anterior mandible.
Fifteen patients with edentulous mandibles participated in the study. In one half of the jaw, between the exit of the nerve-vessel bundle and the midline, one type of implant was placed and in the remaining half the other type. The implants were loaded the day of surgery via a fixed, temporary supra-construction. Ten days later, the permanent one was screw retained to the implant pillars.
The present 18-month clinical trial failed to demonstrate any differences regarding healing and cumulative success rate of an an-oxidized implant surface (TiUnite) and a turned (turned) one when implants in the anterior mandible were exposed to functional load within 24 hours after installation.
A high predictability regarding the treatment outcome for immediately loaded Brånemark implants in the anterior mandible was observed. Furthermore, no difference between the traditional turned and the an-oxidized implant surface (TiUnite) could be observed. However, it has to be stressed that all implants (irrespective of surface) were placed in the anterior mandible and also that all the patients demonstrated a high level of oral hygiene.
本研究的目的是比较在对下颌前部进行跨牙弓设计的固定局部义齿即刻加载时,TiUnite种植体与机加工表面的Branemark系统(诺贝尔生物科技公司,瑞典哥德堡)种植体的治疗效果。
15例下颌无牙患者参与了本研究。在颌骨的一侧,在神经血管束出口与中线之间植入一种类型的种植体,在另一侧植入另一种类型的种植体。种植体在手术当天通过固定的临时上部结构进行加载。10天后,将永久性修复体用螺丝固定在种植体柱上。
在本为期18个月的临床试验中,当在下颌前部植入的种植体在安装后24小时内承受功能负荷时,未能证明抗氧化种植体表面(TiUnite)和机加工表面种植体在愈合和累积成功率方面存在任何差异。
观察到下颌前部即刻加载的Branemark种植体治疗效果具有高度可预测性。此外,未观察到传统机加工表面种植体与抗氧化种植体表面(TiUnite)之间存在差异。然而,必须强调的是,所有种植体(无论表面如何)均植入下颌前部,并且所有患者的口腔卫生状况良好。
