摘要:

当临床中既要进行缺失牙的种植,又要进行余留牙的牙体预备时,利用数字技术将二者进行同期整合是一个减少就诊次数、提升效率的方案。本文提出了一种同期种植与牙体预备技术的数字化流程,将种植手术导板和三维打印定深孔导板同期整合为一个导板,同时完成引导种植体植入与精准牙体预备。以“修复为导向”的虚拟种植规划设计并制作出的种植手术导板,可以提高种植体植入的效率和可预测性,其线性精度要求为1 mm左右;而定深孔导板实现了牙体预备量的精准引导、修复空间可视化,保证了备牙质量,其线性精度要求为百微米级。不同的设计精度需求使得二者的结合提升导板整体的引导精度需求,二者的一体化同期应用也实现了最大程度减少临床操作时间、就诊次数以及患者经济负担的要求。

Abstract:

Using digital technologies in concurrently performing missing tooth implantation and preparation of remaining teeth is a solution to reduce the number of visits and improve efficiency. This paper proposes a digital process for simultaneously implanting and preparing teeth. It integrates implant surgical guide and 3D-printed tooth preparation guide into a single guide and completes guided implant placement and precise tooth preparation. Based on “repair-oriented” virtual implant planning, the implant surgical guide can improve the efficiency and predictability of implant placement, and its linear accuracy is about 1 mm. The tooth preparation guide precisely guides tooth preparation and restoration space visualization, ensuring the quality of the tooth preparation. The two guides have different design accuracy requirements, and thus their combination improves the overall guiding accuracy requirements. The concurrent application of the two guides minimizes the clinical operation time, number of visits, and economic burden of patients.
