测量替牙期前牙反患者治疗前后口周力的分布情况,为替牙期前牙反的预防和临床治疗提供理论依据。临床选取30名替牙期前牙反牙合患者,年龄8岁～12岁,平均年龄10.8岁,其中男性15名,女性15名,测量其治疗前后姿势位时上、下中切牙区唇、舌侧,左右上、下第一前磨牙区颊舌侧,左右上、下第一磨牙区颊舌侧口周力值,分析姿势位时受试者牙弓周围口周力分布变化的情况及规律。治疗前后受试者口周力各区域的分布规律基本一致;值得注意的是治疗后下切牙舌侧不再存在负压现象;治疗前后上中切牙区口周力测量值存在着显著的差异(P<0.05)。口周肌肉等软组织具有适应硬组织改变的功能,随着硬组织结构的改变,口周软组织通过发生相应的变化来维持口颌系统原有平衡、稳定状态。
To measure the distribution of oral force before and after treatment of anti-tarsal anti-palsy patients during the period of molar and to provide theoretical basis for the prevention and clinical treatment of anti-tarsal anti-tarsal teeth. Clinical analysis of 30 anterior occlusal anti-occlusion patients aged from 8 to 12 years old, average age 10.8 years, 15 males and 15 females, measured before and after treatment of position bit in the upper and lower incisors lip , The lingual side, left and right upper and lower first premolar area of the buccal and lingual side, left and right upper and lower first molar area of the buccal and lingual crest value, And the law. Before and after treatment, the distribution of perioral force was basically the same in all the subjects. It is noteworthy that there was no negative pressure on the lingual side of the incisors after treatment, there was a significant difference (P <0.05). Perioral muscle and other soft tissues have the function of adapting to the change of hard tissue. With the change of hard tissue structure, perioral soft tissues maintain the original balance and stable state of oral maxillary system through the corresponding changes.
