目的:比较安氏III类乳牙牙合与正常乳牙牙合的异同,为临床研究乳牙安氏III类牙合病因提供参考。方法:选取乳牙牙合安氏III类儿童29例,对照组组选取安氏I类正常牙合患儿30例,分别对两组的矢状面型、垂直骨面型、牙槽骨高度、软组织形态进行测量。结果:两组儿童除了在垂直骨面型上没有显著性差异外,其他三个方面都有显著性差异。矢状方向上:ANB(患者组-1.6±2.30,正常组2.5±2.41),面突角(患者组-0.77±3.72,正常组7.5±4.47),Wits值(患者组-3.52±3.36,正常组-0.54±1.91),A至N垂直线(患者组-3.35±2.65,正常组0.59±2.71)。牙槽高度包括:U1到NA距离(患者组13.52±6.34,正常组8.46±3.23),IMPA (患者组80.04±5.40,正常组85.97±6.07),上下切牙角(患者组129.65±6.35,正常组127.43±6.34)。软组织测量项目包括软组织面突角(患者组3.44±2.60,正常组11.98±3.23),鼻面角(患者组23.79±4.25,正常组25.36±2.55),上唇至审美平面距(患者组-1.2±1.37,正常组1.26±1.10)。结论:安氏III类患儿与正常儿童的颅面生长发育趋势有显著不同,应该予以早期干预。
目的:比較安氏III類乳牙牙閤與正常乳牙牙閤的異同,為臨床研究乳牙安氏III類牙閤病因提供參攷。方法:選取乳牙牙閤安氏III類兒童29例,對照組組選取安氏I類正常牙閤患兒30例,分彆對兩組的矢狀麵型、垂直骨麵型、牙槽骨高度、軟組織形態進行測量。結果:兩組兒童除瞭在垂直骨麵型上沒有顯著性差異外,其他三箇方麵都有顯著性差異。矢狀方嚮上:ANB(患者組-1.6±2.30,正常組2.5±2.41),麵突角(患者組-0.77±3.72,正常組7.5±4.47),Wits值(患者組-3.52±3.36,正常組-0.54±1.91),A至N垂直線(患者組-3.35±2.65,正常組0.59±2.71)。牙槽高度包括:U1到NA距離(患者組13.52±6.34,正常組8.46±3.23),IMPA (患者組80.04±5.40,正常組85.97±6.07),上下切牙角(患者組129.65±6.35,正常組127.43±6.34)。軟組織測量項目包括軟組織麵突角(患者組3.44±2.60,正常組11.98±3.23),鼻麵角(患者組23.79±4.25,正常組25.36±2.55),上脣至審美平麵距(患者組-1.2±1.37,正常組1.26±1.10)。結論:安氏III類患兒與正常兒童的顱麵生長髮育趨勢有顯著不同,應該予以早期榦預。

Objective To compare the Angle Class III occlusion in deciduous dentition with normal occlusion,to provide reference for the cause of Angle Class III malocclusion. Methods 29 children in deciduous dentition with Angle Class III occlusion were selected for a group,and 30 children in deciduous dentition with normal occlusion were classified in control group. Two groups are measured of sagittal and vertical skeletal analysis,alveolar bone height analysis and soft tissue analysis. Results In addition to the alveolar bone height there was no significant difference, the other three were significant differences.Sagittal direction:ANB (Class III group:- 1.6±2.30,normal 2.5±2.41), surface process angle (Class III group:- 0.77±3.72,normal group:7.5±4.47),Wits appraisal (Class III group:-3.52±3.36, normal group:0.54±1.91),and A to N- perpendicular (Class III group: - 3.35±2.65;normal group:0.59±2.71). Dentoalveolar measurements included U1 to NA (Class III group:13.52±6.34;normal group:8.46±3.2),IMPA (Class III group:80.04±5.40;normal group:85.97±6.07,and inter incisal angle (Class III group: 129.65±6.35;normal group:127.43±6.34). Soft tissue measurements included soft tissue convexity (Class III group:3.44±2.60;normal group:11.98±3.23),naso facial angle (Class III group:23.79±4.25;normal group:25.36±2.55), and upper lip to esthetic plane (Class III group: - 1.2±1.37;normal group:1.26±1.10). Conclusion Between children with Angle Class III malocclusion and those with normal craniofacial growth,there are signi?cant differences. Children with Angle Class III malocclusion should be early treated.
