前磨牙正锁(牙合)对下颌骨矢状向位置的影响
|
摘要
目的 :研究前磨牙正锁?对青少年下颌骨矢状向位置的影响,为正确诊断和掌握正畸治疗时机及制定合理临床治疗方案提供参考。方法:选择2004—2017年间就诊于中国医科大学附属口腔医院正畸科的前磨牙正锁?青少年患者100例为研究对象,其中男54例、女46例,单侧前磨牙正锁?70例、双侧前磨牙正锁?30例。选用其正畸治疗前的X线头颅侧位片,利用Winceph 9.0软件测量16项上、下颌骨矢状向相关硬组织指标,采用SPSS 21.0软件包将所得测量数据与正常?标准值进行比较。结果:研究组区分单侧前磨牙正锁?与双侧前磨牙正锁?,与正常值相比,Beta角、SNB、SND、ANB、AB平面角、APDI、颌凸角、面角、Wits值、S-Co、Co-Po的差异均有统计学意义(P<0.05)。相比于正常值,单侧前磨牙正锁?组Go-Pog差异亦有统计学意义(P<0.05)。结论:青少年前磨牙正锁?患者,矢状向上颌骨位置正常,下颌骨位置后退,有形成骨性Ⅱ类面型的趋势。前磨牙正锁?影响下颌骨发育,导致下颌体、下颌骨长度偏小。提示正畸诊治过程中,应提高对青少年前磨牙正锁?的关注,及早进行正畸治疗,预防对下颌骨发育及矢状骨面型造成的不利影响。
PURPOSE: To study the effect of adolescent premolar scissor bite on the sagittal position of mandible and provide proper reference for correct orthodontic diagnosis and right time to treatment. METHODS: One hundred adolescents(54 females, 46 males) with scissor bite of premolars(70 were unilateral,30 were bilateral) were selected as experimental group between 2004 to 2017 from the Department of Orthodontics, Stomatological Hospital of China Medical University. Among them, 54 females served as female group, 46 males served as male group; 30 were bilateral and 70 were unilateral. Lateral cephalograms were recorded before treatment. 16 sagittal hard tissue variables on maxilla and mandible were measured cephalometrically by Winceph 9.0 software, and the cephalometric data were analyzed statistically by using SPSS 21.0 software package. RESULTS: Compared with normal occlusion, Beta angle, SNB, SND,ANB, AB-Plane angle, APDI, convexity angle, facial angle, Wits, Co-Po showed statistically significant difference in both unilateral group and bilateral group(P <0.05). In addition, Go-Pog showed statistically significant difference between normal occlusion and unilateral group(P <0.05). CONCLUSIONS: Adolescents with premolar scissor bite restricts the sagittal position of mandible and tend to have skeletal Ⅱ sagittal jaw relationship. Scissor bite affects the growth of mandible and makes mandibular body length and mandibular length less than normal. More attention should be paid to scissor bite as early as possible to decrease the harmful effects on growth of mandible and sagittal jaw relationship.
