Human bite forces have been studied with several types of equipment, and the maximal values reported have varied greatly. In the present study, a new bite force recorder was developed to measure human bite forces. When measuring maximal bite force, the mandible is, laterally and sagittally, almost in the intercuspal position, while the vertical opening of the jaws in the molar region is about 14 mm. Several teeth bite upon the housing. A quartz force transducer serves as a sensory unit. A microprocessor produces a numeric result, shown on a liquid crystal display (LCD). In order to adapt the sensor to be a part of a bite force recorder, we designed a unilateral housing of nonhardened tool steel. In laboratory calibration tests, a series of loads from 112.8 to 1691.5 N was used. The maximal bite forces of healthy undergraduate dental students, 15 men and 15 women, were investigated. The results for both genders remarkably exceeded the values previously reported for unilateral housings. The mean maximal bite force value in the molar region was 847 N for men and 597 N for women. The finding that pain or lack of muscular strength most often limited the clenching suggests that the actual masticatory potential was registered.
人们已经使用多种类型的设备对人类咬合力进行了研究，报告的最大值差异很大。在本研究中，开发了一种新的咬合力记录器来测量人类咬合力。测量最大咬合力时，下颌在横向和矢状面上几乎处于牙尖交错位，而磨牙区颌骨的垂直开口约为14毫米。几颗牙齿咬在外壳上。一个石英力传感器作为传感单元。一个微处理器产生一个数字结果，显示在液晶显示屏（LCD）上。为了使传感器成为咬合力记录器的一部分，我们设计了一个由非硬化工具钢制成的单侧外壳。在实验室校准测试中，使用了一系列从112.8到1691.5牛的载荷。对15名男性和15名女性健康本科牙科学生的最大咬合力进行了研究。两性的结果均显著超过了先前单侧外壳报告的值。男性磨牙区的平均最大咬合力值为847牛，女性为597牛。疼痛或肌肉力量不足最常限制咬紧这一发现表明实际咀嚼潜力已被记录下来。
