摘要
牙槽嵴骨量严重不足极大影响着种植体的植入和种植修复后的长期稳定性,引导骨再生在骨增量方面效果稳定。3D打印数字化个性化钛网是实现理想牙槽嵴骨增量的一种新方法,对骨量不足拟行种植修复的患者,完善术前检查,通过影像学、口内或模型扫描获取牙槽骨及牙列信息,以修复为导向设计种植体植入位置,并规划预期骨增量范围及个性化钛网形状,利用3D打印技术制备个性化钛网。该技术有助于精确、个性化重建骨缺损区的牙槽嵴三维形态。本文拟对患者的术前评估、个性化钛网设计要点、临床应用程序及注意事项进行阐述,以期推动该技术在临床中的广泛安全应用。
Severe alveolar bone defects seriously affect dental implant placement and its long-term performance.Guided bone regeneration(GBR)as a reliable technique is able to achieve predictable bone augmentation.Three-dimensional printed digital customized titanium mesh is a new technique to obtain alveolar bone augmentation.For patients with severe alveolar bone defects,the preoperative examination is performed,the information of alveolar and dentition is obtained by radiographic examination and oral scan or model scan respectively,then the implants position is placed according to the principle of prosthetic-driven implant placement.The extent of bone augmentation and the shape of customized titanium mesh are designed with software,and then the digital customized titanium mesh is manufactured with 3D printing technology.The application of customized titanium mesh is conducive to reconstruct the three-dimensional shape of alveolar ridge precisely,and individually.The aim of this article is to summarize pre-opreative evaluation of patients,the key points of the design,clinical application and precautions of customized titanium mesh,in order to further promote its wide and safe application in clinical practice.
