标题： VBCD: A Voxel-Based Framework for Personalized Dental Crown Design

摘要： 从口内扫描设计修复牙冠对牙科技术人员来说是劳动密集型的工作。 为解决这一挑战，我们提出了一种新颖的基于体素的自动化牙冠设计框架（VBCD）。 VBCD框架从体素化的口内扫描生成初始粗略的牙冠，然后通过一个包含距离感知监督的细粒度优化器来提高准确性和质量。 在训练阶段，我们采用曲率和边缘线惩罚损失（CMPL）来增强生成的牙冠与边缘线的对齐度。 此外，引入了基于FDI牙齿编号系统的定位提示，以进一步提高生成的牙冠的准确性。 在大规模口内扫描数据集上的评估表明，我们的方法优于现有方法，为个性化牙冠设计提供了一个稳健的解决方案。 显示英文摘要

摘要： The design of restorative dental crowns from intraoral scans is labor-intensive for dental technicians. To address this challenge, we propose a novel voxel-based framework for automated dental crown design (VBCD). The VBCD framework generates an initial coarse dental crown from voxelized intraoral scans, followed by a fine-grained refiner incorporating distance-aware supervision to improve accuracy and quality. During the training stage, we employ the Curvature and Margin line Penalty Loss (CMPL) to enhance the alignment of the generated crown with the margin line. Additionally, a positional prompt based on the FDI tooth numbering system is introduced to further improve the accuracy of the generated dental crowns. Evaluation on a large-scale dataset of intraoral scans demonstrated that our approach outperforms existing methods, providing a robust solution for personalized dental crown design.
