A study was undertaken to evaluate the safety and efficacy of Durapatite cones as an immediate submerged-root implant in the mandibular symphysis region. The study involved 30 patients of which 15 received 96 implants and the other 15 served as controls. The clinical and radiographic results revealed the implants to be well-accepted by alveolar bone. No evidence of rejection or major complications were observed. The principal problem which occurred was dehiscence of mucosa over some implants. This problem was attributed to operative technique. There was significantly less vertical bone loss and contour change in the anterior part of mandible in the implant group than in the control group.
开展了一项研究，以评估磷酸三钙锥体作为下颌骨联合区域即刻植入牙根的安全性和有效性。该研究涉及30名患者，其中15名接受了96颗种植体，另外15名作为对照组。临床和影像学结果显示，种植体被牙槽骨良好接受。未观察到排斥反应或重大并发症的迹象。出现的主要问题是部分种植体上方的黏膜裂开。这个问题归因于手术技术。种植体组下颌前部的垂直骨吸收和轮廓变化明显少于对照组。
