中文摘要:
      数字化医疗技术是口腔正畸领域发展的必然趋势,临床上开始使用正畸弓丝弯制机器人技术辅助弯制正畸弓丝,而正畸弓丝的数字化表达是机器人弯制的前提。由于人类牙齿排列的个性化,弓丝形状设计的复杂性,难以实现精确地个性化正畸弓丝曲线数字化表达。提出一种个性化正畸弓丝曲线交互调整的设计方法,根据托槽上的基准点坐标,定义了正畸弓丝曲线的托槽直线段和过渡曲线段,过渡曲线段由3阶Bezier曲线数学模型构建。参考手工弯制正畸弓丝的过程,基于离散和组合的方式建立了正畸弓丝特殊功能曲的参数化数学模型及数学模型库。通过对托槽直线段的位置调整、过渡曲线段的形状改变、选择插入特殊功能曲的位置和类型的方式,进行了个性化正畸弓丝曲线交互调整方法的研究。基于LABVIEW软件平台设计了交互调整的软件,并进行调整实验,其结果证明个性化正畸弓丝曲线交互调整的方法具有可行性和有效性。
英文摘要:
      Digital medical technology is inevitable trend in the future orthodontic treatment. The robotic technology is used to assist orthodontics archwire bending clincally, and the digital expression of orthodontic archwire is prerequisite of the robotic bending. Because of the individuation of human tooth arrangement and complexity of archwire shape design, it is difficult to realize the precise digital expression of individual archwire. This paper presents an interactive adjustment method for individual orthodontic archwire. Based on reference points on bracket, the straight line segment for bracket and the transitional curve segment are defined in orthodontic wire curve . And the transitional curve segment is constructed by the mathematical model of 3th order Bezier curve. Referred to process of manual bending wire, the mathematical model and model library about special function arch curve are established based on the discrete and combinatorial method. The interactive adjustment method for individual orthodontics archwire is studied by adjusting position of the straight line segment for bracket, shape changes of the transitional curve segment, selecting the position and type of special function arch curve. The experiments are conducted in the interactive adjustment software designed on the LabVIEW software platform. The result shows that the method is feasible and effective.
