目的 研究安氏Ⅱ类1分类错(牙合)患者矫治前中后的咬合功能变化,分析评价固定矫治技术对牙颌功能的影响.方法 选择26名安氏Ⅱ类1分类错(牙合)患者,运用T-scan Ⅱ型咬合测量分析系统,记录其在矫治前、中、后牙尖交错位的(牙合)力(TOF)、(牙合)力不对称指数(AOF)、(牙合)接触点数(NOC)、(牙合)接触面积不对称指数(AOA)、(牙合)力中心点位置(COF)、(牙合)力中心点最大位移(MMCOF)及(牙合)干扰指数(OII)七项指标.结果 与矫治前相比,矫治中TOF及NOC下降,而矫治后升高(P＜0.05),矫治后AOF、AOA、COF、MMCOF及OII均明显下降(P＜0.01).结论 安氏Ⅱ类1分类错(牙合)患者正畸治疗后,咬合功能增强,明显消除了(牙合)不对称等不利因素,咬合功能更加平衡协调.
目的 研究安氏Ⅱ類1分類錯(牙閤)患者矯治前中後的咬閤功能變化,分析評價固定矯治技術對牙頜功能的影響.方法 選擇26名安氏Ⅱ類1分類錯(牙閤)患者,運用T-scan Ⅱ型咬閤測量分析繫統,記錄其在矯治前、中、後牙尖交錯位的(牙閤)力(TOF)、(牙閤)力不對稱指數(AOF)、(牙閤)接觸點數(NOC)、(牙閤)接觸麵積不對稱指數(AOA)、(牙閤)力中心點位置(COF)、(牙閤)力中心點最大位移(MMCOF)及(牙閤)榦擾指數(OII)七項指標.結果 與矯治前相比,矯治中TOF及NOC下降,而矯治後升高(P＜0.05),矯治後AOF、AOA、COF、MMCOF及OII均明顯下降(P＜0.01).結論 安氏Ⅱ類1分類錯(牙閤)患者正畸治療後,咬閤功能增彊,明顯消除瞭(牙閤)不對稱等不利因素,咬閤功能更加平衡協調.

Objective To investigate the change of occlusal function of patients with Class Ⅱ division 1 malocclusion after orthodontic therapy. Methods T-scan Ⅱ was used in 26 orthodontic patients with class Ⅱ division 1 malocclusion. Bite force, occlusal contacts were measured before,during and after orthodontic therapy. The data of total occlusal force (TOF), asyrmmetry index of occlusal force (AOF), number of occlusal contacts (NOC), asymmetry index of occlusal area (AOA),center of force (COF), maximal movement of COF(MMCOF) and occlusal interference index (OII)were recorded. Results Compared with pre-orthodontics, the TOF and NOC during treatment were smaller, while the TOF and NOC were higher after treatment(P＜0. 05). AOF, AOA, COF,MMCOF and OII were significantly decreased (P＜0. 01 )after orthodontic treatment. Conclusions Total occlusal force and occlusal contacts were improved in Class Ⅱ patients after orthodontic treatment.
