[Application of digital bone block in bone augmentation].

Alveolar ridge augmentation is a common method to solve the problem of insufficient bone mass during implant treatment, while shaping bone substitutes during surgery, maintaining space and stability remain challenging. Digital bone block refers to a digital method for making bone grafts suitable for personalized defect shape. With the advancement of digital technology and the development of materials science, the means of realizing digital bone blocks have also undergone a series of updates. This paper summarizes the relevant researches in the past, systematically introduces the workflow, implementation methods, development history and future prospects of digital bone blocks, and provides suggestions and references for clinicians to use digital methods to improve the predictability of bone augmentation outcome.牙槽嵴骨增量是解决种植治疗骨量不足的常见手段，但存在术中骨粉塑形困难、空间维持和稳定性差等问题。数字化骨块是指利用数字化手段制作的针对缺损区形态的个性化骨增量植入材料。随着数字化技术的进步和材料学的发展，数字化骨块的实现手段也经历了一系列更新。本文总结以往相关研究，系统介绍了数字化骨块的工作流程、实现手段、发展历程及未来展望，为临床医师利用数字化手段提高骨增量效果的可预期性提供建议和参考。.
