During the last years, focus has been paid to implant treatment using immediate function protocols, and different approaches to provide patients with temporary constructions have been presented. Most of these techniques involve dental technicians producing the temporary construction, for example, rebuilding existing dentures, acrylic bridges, etc.
The purpose of this prospective clinical study was to evaluate the clinical outcome of a chair-side technique of a cost-effective temporary prosthesis. Fixture survival rate and risk of temporary bridge failure were analyzed.
Thirty-seven partially or totally edentate patients (18 female and 19 male; mean age: 66.7 years) treated with chair-side manufactured temporary restorations (QuickBridge, BIOMET 3i, Palm Beach, Fl, USA) for immediate loading have been evaluated. The prostheses extended from two unit bridges supported by two implants to full-arch construction supported by six implants. The temporary prostheses were monitored from the day of surgery and delivery to the time of replacement with a permanent prosthetic construction 3 to 6 months later.
No implants were lost during the observation time. One (3%) temporary prosthesis fractured and additional two (6%) loosened during the follow-up time.
The study indicated that the tested chair-side concept for manufacturing of temporary prosthesis for immediate loading of dental implants is a viable approach.
在过去几年中，人们一直关注采用即刻功能方案的种植治疗，并提出了为患者提供临时修复体的不同方法。这些技术大多涉及牙科技师制作临时修复体，例如，改造现有的假牙、丙烯酸桥等。
这项前瞻性临床研究的目的是评估一种经济高效的椅旁临时修复体技术的临床效果。分析种植体存留率和临时桥失败的风险。
对37例部分或全部牙列缺失患者（18例女性和19例男性；平均年龄：66.7岁）进行了评估，这些患者接受了椅旁制作的临时修复体（QuickBridge，BIOMET 3i，美国佛罗里达州棕榈滩）用于即刻负重。修复体范围从由两颗种植体支持的双单位桥到由六颗种植体支持的全牙弓修复体。从手术和交付之日起对临时修复体进行监测，直至3至6个月后用永久修复体替换。
在观察期内无种植体丢失。在随访期间，1个（3%）临时修复体折断，另外2个（6%）松动。
该研究表明，所测试的用于即刻负重的牙种植体临时修复体的椅旁制作概念是一种可行的方法。
