目的 :通过X线头影测量分析,评价应用舌刺联合头帽颏兜矫治有不良舌习惯的前牙反患者的疗效。方法 :测量分析25例应用舌刺联合头帽颏兜矫治完成的前牙反患者治疗前、后的X线头颅侧位片,采用SPSS 17.0软件包对19个相关测量项目进行Mann-Whitney U秩和检验和Wilcoxon符号秩检验,比较治疗前、后各项测量指标的差异,分析矫治效果。结果:25例患者均达到良好的矫治效果,上、下颌骨相对矢状向位置关系得到明显改善,前牙反解除。SNA、ANB、颌凸角、U1-SN、U1-NA角、前牙覆盖及上唇到E线的距离均增大,差异显著(P<0.05)。SN-PP、SNOP、L1-MP、L1-NB角均减小,差异有统计学意义(P<0.05)。与性别有关的2个测量项目ANS-PNS和Cd-Gn线距,治疗后男性及女性均较治疗前显著增大(P<0.05)。结论:舌刺能有效纠正舌不良姿势位,同时促进上颌骨发育,配合头帽颏兜纠正下颌骨前移位,是阻断性矫治有不良舌习惯的前牙反的理想方案。
OBJECTIVE: To evaluate the curative effect of anterior tibial sphenoid calyx in patients with bad tongue habit by applying cephalic thoracotomy combined with headgear chinch pocket through X-cephalometry analysis. Methods: Totally 25 X-ray cephalograms of anterior tibial spondylolisthesis treated with tongue thorn and headgear chinchip were measured and analyzed. Nineteen related items were measured by Mann-Whitney U Rank sum test and Wilcoxon signed rank test to compare the difference of each measurement index before and after treatment and analyze the effect of treatment. RESULTS: Twenty-five patients achieved satisfactory results. The relative sagittal position of the upper and lower jaws was significantly improved, and the anterior crossbite was relieved. The distances between SNA, ANB, maxillary protuberance, U1-SN, U1-NA, anterior teeth cover and upper lip to E line all increased significantly (P <0.05). The SN-PP, SNOP, L1-MP and L1-NB angles decreased, the difference was statistically significant (P <0.05). There was no significant difference in ANS-PNS and Cd-Gn lineage between the two sex-related measures, both men and women were significantly higher than before treatment (P <0.05). Conclusion: Tongue can effectively correct the position of tongue bad posture, and promote maxillary development, with the headgear chin pocket to correct the mandibular anterior displacement, is an ideal solution to block the orthodontic treatment of bad ankles.
