Aim In clinically challenging scenarios with limited bone height and anatomical restrictions, the use of short implants have been proposed as a potential treatment strategy. The purpose of this retrospective study was to evaluate the clinical outcomes of short implants supporting prostheses in the posterior premolar region of the maxilla and mandible.Materials and methods A total of 30 patients requiring short 6 mm length implant placement in the posterior premolar region were included. Following a period of osseointegration, the implants were restored with either single crowns, fixed bridges or implant-supported removable overdentures. Implant and prosthetic survival with technical complications were recorded.Results In total, 45 implants were placed, with four failures reported before loading in two patients, resulting in a patient implant survival rate of 93.3% over the two-year follow-up. There was no statistically significant difference found between implant failure and arch placement. Prosthetic survival was 100% and minor technical complications recorded were low.Conclusion This study showed that short 6 mm implants could provide a viable treatment option, with high survival rates comparable with alternative bone augmentation procedures. Further research with longer observation periods would be required to validate these current findings.
目的 在骨高度有限且存在解剖学限制的临床挑战性情况下,已提出使用短种植体作为一种潜在的治疗策略。本回顾性研究的目的是评估在上颌和下颌后磨牙区域支持修复体的短种植体的临床效果。
材料与方法 共纳入30例需要在后部磨牙区域植入6mm短种植体的患者。经过一段骨整合期后,种植体用单冠、固定桥或种植体支持的可摘覆盖义齿进行修复。记录种植体和修复体的存留情况以及技术并发症。
结果 总共植入了45颗种植体,有两名患者在加载前报告了4颗种植体失败,在两年的随访中患者种植体存留率为93.3%。种植体失败与牙弓位置之间未发现统计学上的显著差异。修复体存留率为100%,记录的轻微技术并发症发生率较低。
结论 本研究表明,6mm的短种植体可以提供一种可行的治疗选择,其高存留率与替代性骨增量手术相当。需要进行更长观察期的进一步研究来验证这些当前的发现。
