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.
在牙修复体领域，将多个种植体固定在一起可提高其稳定性。在进行即刻负重程序时，这种方法可能特别有利，可提高种植体骨结合率，并降低种植体和修复体失败的风险。即刻负重技术（ILT）包括通过使用特意制作的基台，在口腔内将种植体逐对焊接在一起，从而创建一个金属框架来固定种植体。
本研究的目的是调查使用即刻负重技术通过即刻负重修复体修复部分牙列缺损患者时的修复成功率。
对接受即刻负重技术治疗的患者的临床记录进行回顾性评估，并从骨折、崩瓷、松动、螺钉骨折率和黏膜炎方面分析修复成功率。此外，通过测量边缘骨吸收（MBL）来评估种植成功率。
共纳入55例患者（20例男性和35例女性，平均年龄59.8±9.4岁），对应66个修复体。共植入160颗种植体。在最后一次随访时（39.6±28.4个月），1例患者（1.8%；1个修复体（1.5%））出现修复体材料骨折。种植体周围炎影响4颗种植体（2.5%），另有4颗种植体（2.5%）出现透射区，影响5例患者（9.1%）。另外2例患者（3.6%）患有黏膜炎。根据阿尔布雷克特松和扎尔布标准，种植成功率为94.4%。无种植体丢失。种植体水平（0.28±0.56mm）、修复体水平（0.30±0.51mm）和患者水平（0.33±0.54mm）的平均边缘骨吸收值。
即刻负重技术似乎是通过即刻负重修复部分牙列缺损患者的一种可行方法。
