The treatment objectives of open-bite cases which occurs as a result of the excess vertical growth of nasomaxillary complex, increase in the upper and lower posterior vertical dentoalveolar development, downward and backward growth of the mandible are restraining of the growth capacity of these regions and leading the growth of the mandible on the horizontal plane. One of the treatment alternatives of these cases is the spring-loaded posterior bite block; a functional orthopedic appliance. In this case report which the effects of spring-loaded posterior bite block therapy on craniofacial and dentoalveolar structures have been shown; three cases having chronological ages of 9 years 8 months; 10 years 4 months and 10 years 1 month were presented and the treatment results were discussed. The common effects of spring-loaded posterior bite-block therapy observed in three cases are; the restraint of the vertical growth of the maxilla and of both lower-upper posterior dentoalveolar structures, change in the growth pattern of the mandible from vertical towards horizontal plane.
由于鼻上颌复合体垂直生长过度、上下后牙牙槽垂直发育增加以及下颌向下向后生长导致的开颌病例，其治疗目标是抑制这些区域的生长能力，并引导下颌在水平面上生长。这些病例的治疗选择之一是弹簧加载式后牙咬合垫，一种功能性矫形器具。在本病例报告中展示了弹簧加载式后牙咬合垫治疗对颅面和牙牙槽结构的影响；介绍了3例年龄分别为9岁8个月、10岁4个月和10岁1个月的病例，并讨论了治疗结果。在3例病例中观察到的弹簧加载式后牙咬合垫治疗的共同效果是：上颌以及上下后牙牙槽结构垂直生长受到抑制，下颌生长模式从垂直向水平面转变。
