The immediate loading of implants with a porous anodized surface is a well-described technique. Few data are however available on the long-term outcomes.
The aim of this prospective study was to assess the 10-year performance of TiUnite implants supporting fixed prostheses placed with an immediate loading approach in both postextractive and healed sites.
All patients received a fixed provisional restoration supported by immediately loaded parallel design, self-tapping implants with a porous anodized TiUnite surface, and an external-hexagonal connection. Both healed and postextractive cases were included. Success and survival rate for restorations and implants, changes in marginal peri-implant bone level, probing depth measurements, biological or technical complications, and any other adverse event were recorded at yearly follow-up up to 10 years after surgery.
A total of 210 implants fulfilled the inclusion criteria and were consecutively placed in 59 patients. Forty-seven (22.38%) implants were lost because of the recalled patient refused to attend the planned 10-year follow-up. Five over 210 (2.38%) implants were lost. At the final follow-up, the accumulated mean marginal bone loss and probing depth were, respectively, 1.93 mm (SD 0.40) and 2.54 mm (SD 0.44) for the implants placed in healed sites (n = 84); 1.98 mm (SD 0.37) and 2.63 mm (SD 0.39) for the implants placed in postextractive sites (n = 74). The restorations examined achieved a cumulative 65.26% success rate and 97.96% survival rate. The implants placed in healed and postextractive sites, respectively, achieved a 98.05% and a 96.52% cumulative survival rate.
Positive results in terms of bone maintenance in the long-term perspective are to be expected using immediately loaded implants with a TiUnite porous anodized surface in both postextractive and healed sites when adequate levels of oral hygiene are kept.
对具有多孔阳极氧化表面的种植体进行即刻负重是一种已被充分描述的技术。然而,关于其长期效果的数据却很少。
这项前瞻性研究的目的是评估在拔牙后和愈合部位采用即刻负重法植入的支持固定修复体的TiUnite种植体的10年性能。
所有患者均接受由即刻负重的平行设计、带有多孔阳极氧化TiUnite表面和外六角连接的自攻型种植体支持的固定临时修复体。纳入了愈合部位和拔牙后部位的病例。在术后长达10年的每年随访中记录修复体和种植体的成功率和存留率、种植体周围边缘骨水平的变化、探诊深度测量、生物学或技术并发症以及任何其他不良事件。
共有210颗种植体符合纳入标准,并连续植入59例患者体内。47颗(22.38%)种植体因召回患者拒绝参加计划的10年随访而丢失。210颗种植体中有5颗(2.38%)丢失。在最终随访时,愈合部位植入的种植体(n = 84)的累积平均边缘骨吸收和探诊深度分别为1.93 mm(标准差0.40)和2.54 mm(标准差0.44);拔牙后部位植入的种植体(n = 74)的累积平均边缘骨吸收和探诊深度分别为1.98 mm(标准差0.37)和2.63 mm(标准差0.39)。所检查的修复体的累积成功率为65.26%,存留率为97.96%。愈合部位和拔牙后部位植入的种植体的累积存留率分别为98.05%和96.52%。
当保持足够的口腔卫生水平时,在拔牙后和愈合部位使用带有TiUnite多孔阳极氧化表面的即刻负重种植体,从长期来看有望在骨维持方面取得积极结果。
