Immediate implant placement at multirooted molar sites involves a series of site-specific anatomical challenges, including implant bed preparation in the presence of interradicular bone septa. The aim of this article is to present and discuss a novel approach that gives improved guidance during implant bed preparation for immediate implants at multirooted extraction sites in both the mandible and maxilla. Following decoronation of the concerned teeth, osteotomies were performed directly through the teeth's initially retained root complexes. After completion of the drilling protocol, the remaining root aspects were extracted, and treatment was continued in the usual manner. With the osteotomy drills stabilized and guided by the retained root aspects, this approach allows for precise positioning and angulation of the implant bed preparation, thus enabling ideal implant positioning during immediate implant placement at multirooted extraction sites.
多根磨牙部位即刻种植面临一系列特定部位的解剖学挑战,包括在根间骨隔存在的情况下制备种植窝。本文的目的是介绍和讨论一种新方法,该方法在上下颌多根牙拔除部位即刻种植的种植窝制备过程中能提供更好的引导。在相关牙齿去冠后,直接通过最初保留的牙根复合体进行截骨术。完成钻孔操作后,拔除剩余的牙根部分,并以常规方式继续治疗。通过保留的牙根部分稳定并引导截骨钻,这种方法能够精确地定位种植窝制备的位置和角度,从而在多根牙拔除部位即刻种植时实现理想的种植体定位。
