: Immediate implant placement with immediate esthetics has become a more common procedure over time, though ensuring good emergence of the axis of the implant has been a challenge. A novel macroimplant design with an angled platform (Co-Axis) has been developed to ensure exit of the head of the implant in the correct prosthetic position. A systematic literature review was carried to determine the survival rate and marginal bone loss associated with these implants. : An electronic and manual literature search was made in accordance with the PRISMA statement. The search strategy was limited to human studies, retrospective and prospective clinical trials, cross-sectional studies, and cohort studies reporting outcomes of a novel macrohybrid implant with a 12° angled implant connection. : Three articles met the inclusion criteria and were reviewed in the analysis. The estimated success rate was 95.9%. The global marginal bone loss was estimated to be -0.17 ± 0.58 mm in an environment characterized by great heterogeneity (I = 99%). The estimated mean implant stability was 69.6 ± 0.92 (ISQ). As only two studies provided the required information, it was not possible to determine publication bias. Lastly, mean recession was estimated to be practically zero (0.06 ± 0.23 mm), with great heterogeneity. : Within the limitations of this systematic review, it can be affirmed that immediate implant treatment with Co-Axis implants shows a survival rate of 95.9% at one year of follow-up, with low marginal bone loss values, near-zero soft tissue recession, and favorable papilla index values. Nevertheless, the great heterogeneity of the data requires the findings to be interpreted with caution.
随着时间的推移，即刻种植并即刻实现美学效果已成为一种更为常见的手术，不过确保种植体轴线良好穿出一直是一项挑战。一种带有倾斜平台的新型大种植体设计（共轴种植体）已被研发出来，以确保种植体头部在正确的修复位置穿出。进行了一项系统的文献综述，以确定与这些种植体相关的存活率和边缘骨吸收情况。
根据PRISMA声明进行了电子和手动文献检索。检索策略限于人类研究、回顾性和前瞻性临床试验、横断面研究以及报告新型12°倾斜种植体连接的大混合种植体结果的队列研究。
三篇文章符合纳入标准并在分析中进行了综述。估计成功率为95.9%。在异质性很大的环境中（I = 99%），总体边缘骨吸收估计为-0.17±0.58毫米。估计种植体平均稳定性为69.6±0.92（ISQ）。由于只有两项研究提供了所需信息，因此无法确定发表偏倚。最后，平均牙龈退缩估计几乎为零（0.06±0.23毫米），异质性很大。
在本系统综述的局限性范围内，可以肯定的是，使用共轴种植体的即刻种植治疗在随访一年时显示出95.9%的存活率，边缘骨吸收值低，软组织退缩接近零，乳头指数值良好。然而，数据的巨大异质性要求对研究结果进行谨慎解读。
