To assess the technical and biological complications of screw- and cement-retained implant-supported full-arch dental prostheses.
An electronic search was conducted on Medline/PubMed and Cochrane databases in February 2019; irrespective of any time restrictions using MeSH terms. All studies were first reviewed by abstract and subsequently by full-text reading. Further hand search was performed to identify other related references. Articles only related to cement-retained and/or screw-retained reconstructions in full-arch fixed dental prostheses (FDP) were included.
The initial literature search resulted in 3670 papers. 3478 articles remained after removing duplicate articles, and 3439 articles were further excluded by the reviewers after the abstract screening, which resulted in a selection of 39 studies. 12 studies were further excluded due to not fulfilling the inclusion criteria. Hand searching resulted in two additional papers being included, and finally, 29 articles were included in this review. Screw-retained full-arch fixed dental prostheses have fewer complications than cemented reconstructions. Biological complications such as marginal bone loss > 2 mm occurred more frequently in cemented reconstructions, and technical complications such as screw-loosening and screw fracture occurred more in screw-retained reconstructions.
Cemented reconstructions exhibited more biological complications (implant loss, bone loss > 2 mm) and screw-retained prostheses exhibited more technical problems. Clinical outcomes were influenced by both fixations in different ways. The screw-retained restorations were more easily retrievable than cemented ones, therefore, technical and eventually biological complications could be treated more easily. For this reason, and for their higher biological compatibility, these reconstructions are preferable.
评估螺钉和粘结剂固位种植体支持的全口义齿修复的技术和生物学并发症。
2019 年 2 月，我们在 Medline/PubMed 和 Cochrane 数据库中进行了电子检索；使用 MeSH 术语，不限制任何时间。所有研究首先通过摘要进行评估，然后通过全文阅读进行评估。进一步进行手工搜索以确定其他相关参考文献。仅纳入与全口固定义齿（FDP）中粘结固位和/或螺钉固位修复有关的文章。
最初的文献检索得到了 3670 篇论文。去除重复文章后，仍有 3478 篇文章，经评审员摘要筛选后，进一步排除 3439 篇，最终选择了 39 项研究。由于不符合纳入标准，又有 12 项研究被排除。手工搜索又有 2 篇文章被纳入，最终有 29 篇文章纳入本综述。螺钉固位全口固定义齿的并发症比粘结固位修复少。粘结固位修复的生物学并发症（种植体丧失、骨丧失>2mm）更常见，而螺钉固位修复的技术并发症（螺钉松动、螺钉断裂）更常见。
粘结固位修复的生物学并发症（种植体丧失、骨丧失>2mm）更多，螺钉固位修复的技术问题更多。两种固定方式以不同的方式影响临床结果。螺钉固位修复体比粘结固位修复体更容易取出，因此，技术和最终的生物学并发症更容易处理。由于这种原因，以及其更高的生物学相容性，这些修复体更可取。
