Implant-supported complete dentures are a common procedure for patients with mandibular edentulism problems. This article documents the protocol for immediate functional loading of fixed transient mandibular prostheses with fully moldable attachments and distal extensions to prevent fractures. A 56-year-old female patient was referred to the Oral Rehabilitation and Implantology Service due to periodontal problems, difficulty in chewing capacity and aesthetic compromise. The patient was treated in a single surgical procedure with dental extractions, guided regularization of the alveolar process and guided placement of five interforaminal implants and placement of functional fixed mandibular prostheses with immediate loading with personalized UCLA'S, distal extensions and short arc occlusal scheme. At 3 months postoperatively, the definitive placement of fixed mandibular metal acrylic prostheses and conventional upper prostheses was performed. The functional and aesthetic integrity of the fixed mandibular prosthesis implant preserved with UCLA'S documents that implant placement in the interforaminal zone with an immediate loading protocol is a viable treatment option for prosthetic rehabilitation of the fully edentulous mandibular arch and that design with distal extensions in the posterior sector of the mandibular arch is an effective option to avoid fracture of the prostheses, presenting a survival of the five mandibular implants of 100% at 1 year postoperatively.
种植体支持的全口义齿是治疗下颌牙列缺失问题患者的常见方法。本文记录了使用完全可塑形附件和远中延伸部对固定临时性下颌假体进行即刻功能加载以防止骨折的方案。一名56岁女性患者因牙周问题、咀嚼能力差和美观受损被转诊至口腔修复与种植科。该患者接受了单次外科手术治疗，包括拔牙、牙槽突引导性整复、五枚孔间种植体引导性植入以及功能性固定下颌假体植入并即刻加载个性化的UCLA修复体、远中延伸部和短弧咬合方案。术后3个月，进行了固定下颌金属丙烯酸酯假体和传统上颌假体的最终植入。使用UCLA修复体保留的固定下颌假体种植体的功能和美观完整性证明，采用即刻加载方案在孔间区植入种植体是全牙列缺失下颌弓修复的可行治疗选择，并且在下颌弓后部采用远中延伸部设计是避免假体骨折的有效选择，术后1年五枚下颌种植体的存留率为100%。
