The use of compression plates for osseous fixation in the inferior maxilla causes some problems for radiation therapy. The retrodiffusion of electrons from the metal implant induces an increased dose at the surface and especially at the metal border. A dose increase up to 40% is demonstrated for the central ray by means of thermoluminescent dosimetry. A dose decrease of up to 90% is measured for 6 MeV behind the inhomogeneity.
在下颌骨使用加压钢板进行骨固定会给放射治疗带来一些问题。电子从金属植入物向后散射会导致表面尤其是金属边界处剂量增加。通过热释光剂量测定法显示，中心射线剂量增加高达40%。在不均匀性后方，6兆电子伏的剂量测量显示减少高达90%。
