摘要
目的评价种植术后即刻修复的临床效果。方法单颗牙缺失,牙槽嵴高度及宽度足够的患者12例,植入种植体,要求种植体植入扭力大于40Ncm,即刻取模,术后3d戴入临时冠,3～6个月后改为烤瓷冠永久修复,定期进行临床及X线片观察,观察种植体的动度、种植体周骨结合情况及边缘骨吸收量。结果12颗种植体均已完成金属烤瓷冠修复,经15～26个月的追踪观察,种植体无一松动或脱落,X线显示种植体骨结合良好,种植体植入后1年种植体周骨高度丧失(0.75±0.22)mm。结论若缺失区骨质情况良好,单牙种植即刻修复可获得满意的近期临床效果。
Objective To evaluate the clinical effectiveness of immediate restoration of the implants. Methods 12 implants were placed into 12 different patients with sufficient bone height and width. Then impressions were made during the implant operation. Provisional acrylic resin crowns were seated 3 days after implantation. The implants were restored with ceramometal prostheses 3 months after implantation. Radiographic and clinical examinations were made at fixed intervals. The stability of implants, peri-implant bone responses were evaluated. Loss in margin bone height was measured by a series of radiographs. Results 12 implants were restored with ceramometal prostheses. No implant was loosen or loss. Positive peri-implant tissue were achieved followed 15 - 26 months. The mean loss in margin bone height was （0.75 ±0.22） mm after 12 months. Conclusion Immediate restoration of implants after implantation can get satisfied clinical effects recently if bone of implant region is good.
