An esthetic peri-implant soft tissue contour is a critical element of the success of implant restorations in the esthetic zone. Once the optimal transmucosal soft tissue profile is formed, it needs to be accurately replicated on the master cast. This clinical technique involves the utilization of a silicone putty positioning index placed in the patient's mouth to accurately duplicate the external contour of teeth and soft tissue. By combining this positioning index with the implant-supported interim crown, the 3D-printed initial cast, which was used to fabricate the interim crown, can be conveniently and efficiently transformed into a definitive master cast.
美观的种植体周围软组织轮廓是种植体修复在美学区域成功的关键因素之一。一旦形成了最佳的黏膜下软组织轮廓，就需要在主模型上准确复制。这种临床技术涉及使用硅橡胶定位印模材料置于患者口中，以准确复制牙齿和软组织的外部轮廓。通过将这个定位指数与种植体支持的临时冠结合起来，可以方便高效地将用于制作临时冠的 3D 打印初始模型转换为最终的主模型。
