背景:在假牙的背景下,将多个植入物夹板连接在一起可以提高它们的稳定性。当执行即时装载程序时,该方法可能特别有利,增加植入物骨整合率,并降低植入物和假体失败的风险。瞬时加载技术(ILT)涉及创建金属框架,通过口内成对地焊接植入物来夹板,使用有目的地创建的基台。
目的:本研究的目的是调查使用ILT通过立即加载的假体修复部分缺牙患者的假体成功。
方法:回顾性评估ILT患者的临床记录,并根据骨折分析了假体的成功率,削片,拧开,螺钉断裂率,和粘膜炎。此外,通过测量边缘骨丢失(MBL)评估植入成功率.
结果:共55例患者(男20例,女35例,平均年龄59.8±9.4岁),相当于66个假体,包括在内。总共放置了160个植入物。末次随访(39.6±28.4个月),1例患者(1.8%;1例假体(1.5%))显示假体材料骨折。种植体周围炎影响4个植入物(2.5%),和4更多的植入物(2.5%)显示出放射性渗透性,影响5例患者(9.1%)。另外两名患者(3.6%)患有粘膜炎。植入成功率,根据Albrektsson和Zarb的标准,为94.4%。没有植入物丢失。植入物水平的平均MBL值,假体水平和患者水平为0.28±0.56毫米,0.30±0.51mm和0.33±0.54mm,分别。
结论:瞬时加载技术似乎是一种可行的方法,可以通过即刻加载来修复部分无牙颌患者。
In the context of dental prostheses, splinting multiple implants together may improve their stability. The approach may be especially favorable when performing immediate loading procedures, increasing the implant osseointegration rate, and reducing the risk of implant and prosthetic failure. The instantaneous loading technique (ILT) involves creating a metal framework to splint the implants by intraorally welding them pair-by-pair, using purposefully created abutments.
The aim of the
study was to investigate the prosthetic success when using ILT to rehabilitate partially edentulous patients through immediately loaded prostheses.
Clinical records of patients treated with ILT were retrospectively assessed, and the prosthetic success rate was analyzed in terms of fractures, chipping, unscrewing, screw fracture rate, and mucositis. Furthermore, the implant success rates were evaluated by measuring marginal bone loss (MBL).
A total of 55 patients (20 males and 35 females with a mean age of 59.8 ±9.4 years), corresponding to 66 prostheses, were included. A total of 160 implants were placed. At the last follow-up (39.6 ±28.4 months), 1 patient (1.8%; 1 prosthesis (1.5%)) showed the fracture of the prosthesis material. Peri-implantitis affected 4 implants (2.5%), and 4 more implants (2.5%) showed radiolucency, affecting 5 patients (9.1%). Two other patients (3.6%) suffered from mucositis. The implant success rate, according to the Albrektsson and Zarb criteria, was 94.4%. No implants were lost. The mean MBL values at the implant level, the prosthesis level and the patient level were 0.28 ±0.56 mm, 0.30 ±0.51 mm and 0.33 ±0.54 mm, respectively.
The instantaneous loading technique appears to be a viable approach to rehabilitating partially edentulous patients through immediate loading.
