To describe a bimaxillary simultaneous immediate loading protocol with full-arch implant-supported fixed prostheses.
A prospective case series of 8 patients who required full-arch rehabilitation was conducted. The main inclusion criteria were patients with teeth that required extraction. At least 1 molar per arch was temporarily employed to stabilize the surgical template and the provisional prosthesis during intraoral relining.
Two upper implants failed in 1 patient. Structural fracture was registered in 3 patients, around 3 months after loading. All of them had bruxism. Three esthetic complications were registered: midline deviation, canting of the oclusal plane and color mismatch.
Although this protocol achieves optimal results, some mechanical complications were encountered. The fracture of the provisional prosthesis is a relatively common mechanical complication but does not seem to jeopardize the final treatment result. Implant-supported full-arch, provisional prosthesis fracture, bimaxillary simultaneous rehabilitation, conical abutments.
描述一种用于全牙弓种植体支持的固定修复体的双颌同时即刻加载方案。
对8例需要全牙弓修复的患者进行了一项前瞻性病例系列研究。主要纳入标准为需要拔牙的患者。在口内重衬期间，每侧牙弓至少使用1颗磨牙来稳定手术模板和临时修复体。
1例患者的2颗上颌种植体失败。3例患者在加载后约3个月出现结构骨折。他们均有磨牙症。记录到3例美学并发症：中线偏移、咬合平面倾斜和颜色不匹配。
尽管该方案取得了最佳效果，但仍遇到了一些机械并发症。临时修复体骨折是一种相对常见的机械并发症，但似乎并不影响最终治疗结果。种植体支持的全牙弓、临时修复体骨折、双颌同时修复、锥形基台。
