摘要
全冠桥义齿数字化修复设计主要包括连接体生成和模型融合两部分。通过定义形态截面线,采用蒙皮剖分的方式,首先生成默认连接体,并能通过控制点编辑连接体曲面;若连接体符合要求,则将连接体边界投影到相邻全冠或桥体上,通过投影曲线裁剪内部区域,最后通过网格双向缝合的方式把全冠、桥体和连接体融合在一起,并光顺融合过渡区域,形成完整的全冠桥修复体,质量好,效率高,满足临床修复需求。
Digital restoration of the full-coveragel crowns and bridges mainly consists of the full crowns design,connector generating and model fusion.Through defining the section template,the default connector can be generated under the guide of the idea of skin,whose curve can be edited by the control point.If the connector meets the requirements,the connector boundary should be projected onto the adjacent full-coveragel crowns or bridges.The inner regions are tailored by the projection curve,and finally the full-coveragel crown,bridge and connector are fused by the mean of bidirectional sew algorithm.And the restoration of the full-coveragel crowns and bridges denture can be obtained by smoothing the transition area.It＇s good quality,high efficiency and can meet the clinical demand.
