这项工作的目的是展示使用光纤传感器测量人造上颌骨内部部件的可能性，并测量由正畸和矫形器具传递到牙列和邻近骨骼的内部张力。用标准光纤写入的布拉格光栅监测上颌牙齿，用多路复用光纤监测上颌骨表面，与牙齿最长轴横向。使用万能试验机评估传感器对施加在牙齿上的垂直和侧向力的灵敏度。当施加0到20牛顿的载荷时，检测到大约0.30纳米的波长位移。通过使用安装在牙列上的标准正畸器具施加力，可以在弓丝激活和口外力期间检测到0.025牛顿到0.035牛顿的力范围。在人工模型中使用内部传感器，可以监测牙齿内部部分和上颌骨内应变发生位置上产生的力。传感器检测到正畸力没有传递到上颌骨表面。这一信息对于阐明和解释正畸治疗过程中牙根吸收和局部疼痛等不良影响是很重要的。
The aim of this work is to show the possibility of using fiber optic sensors to instrument inside parts of an artificial maxilla and measure internal tension transmitted by the orthodontic and orthopedic appliances to the dentition and the adjacent bone. Bragg gratings written in a standard optical fiber were used to monitor the maxillary teeth and a multiplexed fiber was used to monitor the surface of the maxillary bone, transversally to the longest axis of the teeth. A Universal Test Machine was used to evaluate the sensitivity of the sensor to the vertical and lateral forces applied on the teeth. A wavelength shift of approximately 0.30 nm was detected when applying loads ranging from 0 to 20 N. By applying forces using the standard orthodontic appliances installed on the dentition it was possible to detect a range of forces between 0.025 N to 0.035 N during the activation of the arch wire and extra-oral forces. The use of the internal sensors in an artificial model made possible the monitoring of the resulting forces on the internal parts of the teeth and at the position where the strain takes place within the maxilla. The sensors detected that the orthodontic forces were not transmitted to the surface of the maxilla. This information is important to elucidate and to correlate undesirable effects as tooth root absorption and local pain during the orthodontic treatment.
