摘　　要：目的:通过对矫治后模型采用不同量的牙托粉充胶,获得拔牙和不拔牙病例Hawley保持器制作所需牙托粉用量。方法:选择拔牙病例20例,非拔牙病例15例,对每个病例取5次模,翻制5副模型。采用5种不同剂量的牙托粉充胶。通过对充胶后剩余及欠缺量的评估,获得牙托粉的常规用量。结果:拔牙病例制作Hawley保持器上下颌共需约6g牙托粉,非拔牙病例上下颌共需约5.5g。结论:拔牙病例Hawley保持器制作所需牙托粉用量较非拔牙病例少。Objective ：To acquire the normal dosage of denture acrylic in Hawley retainer-making by analyzing different dosage used to different models which had been treated. Methods：20 extraction cases and 15 nonextraction cases were selected. Five models were made for every case and five different dosage of denture acrylic were used.By assessing the surplus and deficit of denture acrylic after retainer-making ,the normal dosage of denture acrylic were aequired.Results：7.5ml denture acrylic was needed in maxillary or mandibular retainermaking with extraction,and 8ml denture acrylic was needed in maxillary or mandibular retainer-making with non-extraction.Conclusion：The dosage of denture acrylic in than that of non-extraction group.
