摘　　要：目的评价拔牙后早期应用卵圆形桥体成形缺牙区软组织形态的临床效果。方法选择上颌前牙区拟拔除患牙后行固定局部义齿修复的患者16例，于拔牙后1～2周行基牙牙体预备并制作树脂临时固定桥，桥体设计为卵圆形，拔牙后3～4个月制作永久修复体。修复完成后第3、6、12和24个月复诊。记录桥体处牙龈乳头指数、龈缘水平、角化龈宽度、改良菌斑指数及改良出血指数。结果本研究随访期内所有义齿行使功能良好。拔牙前及修复后24个月时近中牙龈乳头指数分别为2．19和2．38．远中牙龈乳头指数为2．13和2．31．改良菌斑指数为1．81和0．63，改良出血指数为1．13和0．25，龈缘水平位为10．59mm和10．88mm，角化龈宽度为3．66mm和3．53mm。牙龈乳头指数、龈缘水平和角化龈宽度的差异均无统计学意义（P〉0．05）；而改良菌斑指数和改良出血指数均降低，差异有统计学意义（P〈0．01）。结论拔牙后早期应用卵圆形桥体成形缺牙区软组织形态町获得良好的临床效果。Objective The purpose of this clinical study was to evaluate the effect early using of ovate pontics ＇after tooth-extraction on soft tissue shaping. Methods A total of 16 patients with single hopeless maxillary anterior tooth, who intended to receive fixed partial denture after tooth-extraction, were chosen in the present study. The provisional restora- tions with ovate ponties were made 1 -2 weeks after tooth-extraction, while final restorations were made 3 -4 months la- ter. Gingival papilla index, gingival margin, width of keratinized mucosa, modified plaque index and modified bleeding index were monitored before tooth-extraction and at each recall （3, 6, 12, and 24 months ＇after final restoration）. Results All the prnsthesis were in good function. At the time of tooth-extraction and 24-month recall, the mesial gingival papilla indices were 2.19 and 2.38, while the distal indices were 2.13 and 2.31, respectively. The modified plaque indeice were 1.81 and 0.63, while modified bleeding index were 1. 13 and 0.25, respectively. The gingival margin were 10.59 mm and 10.88 mm, while width of keratinized mucosa were 3.66 mm and 3.53 mm, respectively. The gingival papilla index, gingival margin, and width of keratinized mucosa had no significant difference（ P 〉 0.05 ） , but modified plaque index and modified bleeding index were significantly lower（ P 〈 0.01 ）. Conclusion Using ovate pontics early ＇after tooth-extraction to shape the soft tissue can achieve good clinical effect.
