摘要
目的：评价微型种植体作为垂直向支抗压低前牙和磨牙的有效性。方法：选取9例由于前牙过长,唇齿关系不协调露龈笑的病例及5例由于对颌牙缺失导致磨牙伸长,义齿修复困难的病例,采用微型种植体支抗压低前牙或磨牙。比较压低治疗前后的X线头影测量片,测量上下颌中切牙切缘和磨牙边缘嵴相对于腭平面、下颌平面的压低量。结果：压低前牙的9例患者,治疗后前牙覆牙合达到正常,切缘平均压低4.2mm,露龈笑明显改善。5例压低磨牙病例,4例实现了磨牙的绝对压低,平均压低4.1mm,缺牙区成功进行义齿修复。结论：微型种植体支抗可以实现理想的垂直方向的支抗控制。
Objective：To compare the effect of occlusal splint on changing occlusal contact characters and investigate the mechanism of occlusal splint therapy. Method：34 patients with TMD were treated by occlusal splint .After two month,The changes of occlual contact characters and symptom were recorded and compared with the effect before treatment. Result： The clusion time, lateral disclusion time, distance between center line and center of occlusal force of TMD decreased obviously;Compared with the effect before and after treatment, the incidence rate of the premature contact was lower, however, the lateral and protrusive balanced occlusal contacts as well as protrusive disclusion time showed no significant difference between the two groups. Conclusion：Within the limitations of this study ,the results indicated that ： there was a distinct effect of occlusal splint in correcting clusion time,lateral disclusion time, incidence rate of the premature contact as well as distance between center line and center of occlusal force of TMD. It is important mechanism of occlusal splint to harmonized the occlusion of TMD.
