This study aimed to evaluate the effectiveness of using ultrashort implants in the rehabilitation of jaws of fragile patients. The aim of the study was to retrospectively evaluate the survival rate of full-arch prosthetic rehabilitation on ultrashort implants, length 4 mm, 4 mm in diameter in the premolar and canine area and 4.5 mm in diameter in the molar area, with the insertion torque of 60 Nw and immediate loading. Nineteen patients were evaluated for 3 years clinically and radiographically. The significant majority of the patients at the 3 year follow-up (T4) presented a stable and functional implant-supported prothesis, and the survival rate of the implants was 85%, with a loss of 16 implants on 114 implants. The combination of the innovative implant surfaces and the correct project of the prostheses, with the related implant connection, determined a different timing in the therapy, allowing to obtain an immediate loading, which is currently demanded by patients. This and recent reports on short and ultrashort implant usage in atrophic jaws offer a good solution in critical cases. In conclusion, within the limits of the study, the full-arch rehabilitation with immediate loading on ultrashort implants showed good results with few postoperative complications and related low biological cost.
本研究旨在评估使用超短种植体修复脆弱患者颌骨的有效性。该研究的目的是回顾性评估全牙弓修复体在超短种植体上的存活率，这些种植体长度为4mm，前磨牙和尖牙区域直径为4mm，磨牙区域直径为4.5mm，植入扭矩为60Nw并即刻负重。对19名患者进行了为期3年的临床和影像学评估。在3年随访期（T4）时，绝大多数患者的种植体支持义齿稳定且功能良好，种植体存活率为85%，114颗种植体中有16颗出现松动。创新的种植体表面与义齿的正确设计以及相关的种植体连接方式相结合，决定了治疗的不同时机，从而实现了患者目前所期望的即刻负重。这一研究以及近期关于在萎缩性颌骨中使用短种植体和超短种植体的报道，为关键病例提供了一个良好的解决方案。总之，在本研究的范围内，超短种植体即刻负重的全牙弓修复效果良好，术后并发症少，生物学成本低。
