Immediate implant-loading protocol has progressed because of various clinical advantages offered by this treatment approach. However, available studies on edentulous patients are still few compared to those in which delayed implant-loading protocol was applied.
This prospective study was to evaluate the implant survival rate and the peri-implant tissue response in a group of patients who received two unsplinted immediately loaded dental implants in the mandibular anterior region to retain a complete overdenture using locator attachments.
A total of 24 edentulous patients with a mean age of 63.4 years were involved in this study following certain inclusion criteria. All patients received a new set of complete dentures before implant positioning. Two Prima Connex tapered implants were put in the interforaminal area of the mandible with a flapless surgical procedure, and the prefabricated dentures were immediately retained with a zest locator attachment. Clinical and radiographic records of the patients were reviewed immediately after placement of the implant, at 3 months, and at 1, 2, and 3 years following fixture installation. The obtained data were analyzed using paired samples t-test and the Wilcoxon signed-rank test at 0.05 significance level.
At 3 years, all implants had osseointegrated with a 100% survival rate. In addition, the total mean marginal bone change was -0.89 ± 0.14 mm, and the mean periotest value was -7.631 ± 0.921.
Results of this study propose that immediate loading of mandibular implant overdentures that are retained with locator attachments was a feasible treatment alternative for this particular group of patients.

即刻种植体加载方案因其提供的各种临床优势而不断发展。然而，与应用延迟种植体加载方案的研究相比，关于无牙患者的现有研究仍然较少。
本前瞻性研究旨在评估一组在下颌前部区域接受两颗未用夹板固定的即刻加载牙种植体以使用定位器附件保留全口覆盖义齿的患者的种植体存活率和种植体周围组织反应。
按照一定的纳入标准，共有24名平均年龄为63.4岁的无牙患者参与本研究。所有患者在种植体植入前均接受了一套新的全口义齿。通过无瓣手术在下颌孔间区域植入两颗Prima Connex锥形种植体，并立即使用热情定位器附件固定预制义齿。在种植体植入后、3个月时以及种植体安装后1、2和3年对患者进行临床和影像学记录。使用配对样本t检验和Wilcoxon符号秩检验在0.05显著性水平下对获得的数据进行分析。
3年后，所有种植体均实现骨整合，存活率为100%。此外，总的平均边缘骨变化为-0.89±0.14毫米，平均牙周测试值为-7.631±0.921。
本研究结果表明，对于这一特定患者群体，使用定位器附件保留的下颌种植覆盖义齿即刻加载是一种可行的治疗选择。
