本文介绍了激光实时全息法用于双尖牙受力分析的研究。模型试验表明 :在双尖牙牙尖部位及牙颈部位有明显的应力集中 ,牙尖部位受力较大 ,牙颈部位次之 ,折裂大多从两牙尖的正中裂开 ,折裂方式与临床观察相吻合。本文对此进行了相应的分析 ,并对牙骨质剥落等问题提出防治的建议。 This article describes the laser real-time holographic method for the study of the force analysis of bicuspids. The model test shows that there is obvious stress concentration in the cusp tip and the cervical part of the canine, the stress on the cusp tip is larger, the cervical part is the second, and the fracture mostly splits and fractures from the center of both cusp tips Way consistent with clinical observations. This article has carried on the corresponding analysis to this, puts forward the prevention and cure suggestion to the cementum spalling and so on.
