An intracoronal technique for semipermanent splinting of mobile or migrating teeth is described and clinically evaluated. Circumferential grooves of 1 to 1.5 mm depth were cut into the enamel in the occlusal third of the teeth to be splinted. The teeth were splinted by placing a polyester ligature in two or more figure-8 loops along the grooves, and sealing the grooves and interproximal contact areas with an acid-etch composite resin system. A total of 51 splints involving 183 teeth and 132 interproximal contact areas were placed in 34 patients. One year after insertion, 46 splints were found intact. Five splints presented with one fractured interdental element, each. Average mobility of the splinted teeth was 51% below the preoperative level. Splinting improved the masticatory comfort. The esthetic results were satisfactory.
本文描述了一种用于半永久性固定松动或移位牙齿的冠内技术，并进行了临床评估。在待固定牙齿的咬合面三分之一的牙釉质上切割深度为1至1.5毫米的环形凹槽。通过沿着凹槽在两个或更多个8字形环中放置聚酯结扎线来固定牙齿，并用酸蚀复合树脂系统密封凹槽和邻面接触区域。34例患者共放置了51个夹板，涉及183颗牙齿和132个邻面接触区域。插入后一年，发现46个夹板完好无损。5个夹板各有一个牙间元件断裂。固定牙齿的平均松动度比术前水平低51%。固定改善了咀嚼舒适度。美学效果令人满意。
