Dental implant therapy is a common clinical treatment for missing teeth. However, the esthetic result is not as satisfactory as expected in some cases, especially in the anterior maxillary area. Poor esthetic results are caused by inadequate preparation of the hard and soft tissues in this area before treatment. The socket shield technique may be an alternative for a desirable esthetic outcome in dental implant treatments.
In the present systematic review, PubMed-Medline, Google Scholar, and ScienceDirect were searched for clinical studies published from January 2000 to December 2018.
Twenty studies were included, comprising one randomized controlled trial, two cohort studies, 14 clinical human case reports, and three retrospective case series. In total, 288 patients treated with the socket shield technique with immediate implant placement and follow-up between 3-60 months after placement were included. A quality assessment showed that 12 of the 20 included studies were of good quality. Twenty-six of the 274 (9.5%) cases developed complications or adverse effects related to the socket shield technique. Most studies reported implant survival without the complications (90.5%); most of the cases that were followed up for more than 12 months after implant placement achieved a good esthetic appearance. The failure rate was low without the complications, although there were some failures due to failed implant osseointegration, socket shield mobility and infection, socket shield exposure, socket shield migration, and apical root resorption.
The socket shield technique can be used in dental implant treatment, but it remains difficult to predict the long-term success of this technique until high-quality evidence becomes available.
种植牙治疗是一种常见的缺牙临床治疗方法。然而，在某些情况下，特别是在前上颌区域，其美学效果并不如预期的那样令人满意。治疗前该区域软硬组织准备不足是导致美学效果不佳的原因。在种植牙治疗中，种植体套筒防护技术可能是一种理想的美学效果替代方法。
在本次系统评价中，检索了 2000 年 1 月至 2018 年 12 月期间发表的临床研究，包括 PubMed-Medline、Google Scholar 和 ScienceDirect。
共纳入 20 项研究，包括 1 项随机对照试验、2 项队列研究、14 项临床病例报告和 3 项回顾性病例系列研究。共纳入 288 例采用种植体套筒防护技术即刻种植并在种植后 3-60 个月随访的患者。质量评估显示，20 项纳入研究中有 12 项质量较好。274 例（9.5%）病例出现与种植体套筒防护技术相关的并发症或不良反应。大多数研究报告了无并发症的种植体存活率（90.5%）；大多数在种植体植入后随访 12 个月以上的病例获得了良好的美学外观。无并发症的情况下，失败率较低，但也有一些因种植体骨整合失败、种植体套筒移动和感染、种植体套筒暴露、种植体套筒迁移和根尖根吸收而导致的失败。
种植体套筒防护技术可用于种植牙治疗，但在高质量证据出现之前，很难预测该技术的长期成功率。
