Documenting complex three-dimensional (3D) cleft lip and palate malformation with plaster casts based on maxillary impressions is standard care. Presurgical orthopedic treatment also requires an impression. Digital impression-taking in patients with cleft lip and palate is feasible, but procurement costs hinder clinical implementation. Individualized impression trays allow for a precise impression, limiting airway risk. The authors present an open-source impression tray library with scalable impression trays not requiring 3D modeling knowledge. The cleft lip and palate impression tray library is accessible on Open Science Framework. Different shapes are available, and the tray size is selected based on the tuber distance. This allows 3D printing with biocompatible material at the point of care complying with local regulations. The open-source cleft tray library presented offers a hybrid solution for cleft centers, pending the implementation of digital impression.
用基于上颌印模的石膏模型来记录复杂的三维（3D）唇腭裂畸形是标准的护理方法。术前矫形治疗也需要印模。在唇腭裂患者中进行数字化印模是可行的，但采购成本阻碍了临床应用。个体化印模托盘可实现精确印模，降低气道风险。作者提出了一个开源印模托盘库，其中包含可缩放的印模托盘，不需要 3D 建模知识。唇腭裂印模托盘库可在开放科学框架上获得。有不同的形状可供选择，托盘尺寸根据结节距离选择。这允许在符合当地规定的情况下在护理点使用生物相容性材料进行 3D 打印。所提出的开源腭裂托盘库为等待数字化印模实施的腭裂中心提供了一种混合解决方案。
