A prospective clinical pilot study was carried out to evaluate a novel macroimplant design with a 12-degree angled platform. Twelve patients were enrolled in an immediate implant placement procedure with immediate esthetic rehabilitation to replace an anterior maxillary tooth and were treated with implants having an inverted body-shift design with a 12-degree angled neck. Only type I sockets (according to the Elian classification) were considered eligible for the study. The implant was placed at the center of the socket to optimize the alveolar bone and idealize the prosthetic emergence profile. There were no implant failures after 1 year of loading. Regarding the horizontal and vertical hard tissue changes, there was a statistically significant median overall horizontal change of -0.99 mm at 1 mm and -0.61 mm at 3 mm. On the other hand, outcomes were stable at 5 mm, and there was no statistical significance. The median pink esthetic score at the 1-year follow-up was 11.5. This implant may be useful in immediate tooth replacement at maxillary anterior postextraction sockets. Nevertheless, comparative studies with conventional implants should be performed.
进行了一项前瞻性临床试点研究，以评估一种具有12度角平台的新型大植入物设计。12名患者接受了即刻种植体植入手术并进行即刻美学修复，以替换上颌前牙，使用的种植体具有12度角颈部的倒置体移位设计。仅I型牙槽窝（根据埃利安分类）被认为符合该研究条件。种植体放置在牙槽窝中心，以优化牙槽骨并使修复体的龈缘轮廓理想化。加载1年后没有种植体失败。关于水平和垂直硬组织变化，在1毫米处总体水平变化的中位数为-0.99毫米，在3毫米处为-0.61毫米，具有统计学意义。另一方面，在5毫米处结果稳定，没有统计学意义。1年随访时粉色美学评分的中位数为11.5。这种种植体可能有助于上颌前牙拔除后即刻牙齿替换。然而，应与传统种植体进行对比研究。
