摘　　要：目的评估片段弓固定法与高强纤维夹板固定法在外伤移位前牙固定术中的临床效果。方法将34例因训练和运动导致上前牙移位和半脱位的门诊军人随机分成两组,分别采用片段弓固定法与高强纤维夹板固定法进行复位固定,8周后通过临床和X线检查,比较其临床应用效果。结果两组34例患者固位效果稳固、无松脱,牙龈组织健康;去除固定后检查外伤牙均无松动,无叩痛;X线检查未见牙槽骨及牙根吸收现象。在即刻效果的美观、舒适方面高强纤维夹板固定法优于片段弓固定法。结论对于外伤所致的上前牙移位和半脱位患者,两种固定法均可有效的固定松动患牙;高强纤维夹板固定法更为美观和舒适,是松动牙固定较为理想的选择。Objective To compare the clinical effects of segmented arch technique and glass fiber reinforced composite resin dental splint method on the fixation of loose anterior teeth caused by trauma.Methods 34 patients with traumatic loose teeth were chosen as specimens,they were randomly divided into two groups,one of which treated with segmented arch technique,the other treated with glass fiber reinforced composite resin dental splint.Fixation lasted for 8 weeks.The clinical effect was compared through the clinical examination and x-ray.Results The segmented arch and glass fiber reinforced composite resin dental splint were stable and the periodontal tissue was healthy in 34 patients.The alveolar bone had not absorbed and the traumatic loose teeth were not movement any more even though the fixed appliances were taken out.Glass fiber reinforced composite resin dental splint method is better in comfortable and beautiful than segmented arch technique.Conclusion The segmented arch technique and glass fiber reinforced composite resin dental splint all are the good approach to the fixation of loose teeth,but the glass fiber reinforced composite resin dental splint is more esthetic and more comfortable.
