Customized healing abutments are utilized to enhance aesthetics and peri-implant soft and hard tissue health, and play a crucial role in the implant-prosthetic workflow. This systematic review was performed to assess and compare the clinical outcomes of customized healing abutments with conventional ones.
The review was registered with PROSPERO (ID: CRD42024532449) and followed the PRISMA-guidelines. The PICO-question addressed was: "In patients with dental implants, do customized healing abutments result in beneficial peri-implant conditions compared with conventional healing abutments?" Clinical trials involving immediate and late implant placement that compared different healing abutments based on quantifiable outcomes were included. The "PubMed", "PubMed Central", "Cochrane Library", and "Web of Science databases" were screened for eligible studies until 4/20/2024.
Of 1,396 titles retrieved, 5 studies met the inclusion criteria and were analyzed. The included studies showed a low risk of bias as assessed by the RoB2 tool and Joanna Briggs Institute Critical Assessment questionnaire. Compared to conventional healing abutments, customized abutments were associated with a trend toward better clinical outcomes in peri-implant soft and hard tissue, as well as aesthetics. Several results within the cohorts using customized healing abutments showed significantly improved values in soft and hard tissue results as well as aesthetic parameters. Importantly, none of the included studies reported biological or aesthetic disadvantages associated with the use of customized healing abutments.
Customized healing abutments maintain stability of peri-implant hard and soft tissue. However, further studies with larger sample sizes and longer follow-up periods are needed to validate these findings.
定制愈合基台用于提高美观度以及种植体周围软硬组织的健康水平，在种植修复流程中起着关键作用。本系统评价旨在评估和比较定制愈合基台与传统愈合基台的临床效果。
本评价在PROSPERO（注册号：CRD42024532449）进行注册，并遵循PRISMA指南。提出的PICO问题为：“在牙种植患者中，与传统愈合基台相比，定制愈合基台是否能带来有益的种植体周围状况？”纳入了涉及即刻和延期种植的临床试验，这些试验基于可量化结果比较了不同的愈合基台。检索了“PubMed”、“PubMed Central”、“Cochrane图书馆”和“Web of Science数据库”，以查找符合条件的研究，截至2024年4月20日。
在检索到的1396篇标题中，有5项研究符合纳入标准并进行了分析。根据RoB2工具和乔安娜·布里格斯研究所批判性评估问卷评估，纳入的研究显示偏倚风险较低。与传统愈合基台相比，定制基台在种植体周围软硬组织以及美观度方面有临床效果更好的趋势。在使用定制愈合基台的队列中，一些结果显示软硬组织结果以及美学参数有显著改善。重要的是，纳入的研究均未报告使用定制愈合基台存在生物学或美学方面的劣势。
定制愈合基台可维持种植体周围软硬组织的稳定性。然而，需要进一步开展样本量更大、随访期更长的研究来验证这些发现。
