The single midline implant in the edentulous mandible is a treatment concept that has often been controversially discussed. Nearly 30 years ago, the first available clinical results revealed high implant survival rates and remarkable improvements in oral comfort, function, patient satisfaction and oral health-related quality of life for edentulous patients compared to the situation with no implant. However, the clinical trials were predominantly conducted with a small number of patients over a short to medium follow-up period. Today, numerous clinical investigations on the single midline implant in the edentulous mandible, which increasingly include longer-term observation periods, are available. It is the aim of this overview to present the current literature and to highlight the clinical problems. This article is a 2023 update of a review published by the authors in the German language in 2021 in the German journal . In total, 19 prospective clinical trials with a follow-up period of 0.5-10 years were analyzed. Over this observation period, single implants with modern rough implant surfaces in the edentulous mandible reveal high implant survival rates of between 90.9 and 100% when a conventional delayed loading protocol was applied.
在下颌无牙区植入单颗中线种植体是一个常被争议性讨论的治疗理念。近30年前，首批可得的临床结果显示，与未植入种植体的情况相比，种植体的存活率很高，无牙患者的口腔舒适度、功能、患者满意度以及与口腔健康相关的生活质量都有显著改善。然而，这些临床试验主要是在少数患者中进行，随访期为短期至中期。如今，有大量关于下颌无牙区单颗中线种植体的临床研究，其中越来越多的研究纳入了更长的观察期。本综述的目的是呈现当前的文献，并突出临床问题。本文是作者于2021年以德文发表在德国期刊上的一篇综述的2023年更新版。总共分析了19项随访期为0.5至10年的前瞻性临床试验。在这个观察期内，当下颌无牙区使用具有现代粗糙种植体表面的单颗种植体并采用传统的延迟加载方案时，种植体存活率在90.9%至100%之间，显示出较高的存活率。
