摘　　要：目的:研究根形骨块移植治疗上颌骨前部骨量不足的效果。方法:通过对7例患者前牙区的26个牙位进行根形植骨术,重建牙槽骨的形态后植入种植体,术后随访时间平均10个月。结果:重建的牙槽骨唇侧丰满,骨面根形逼真,种植体无松动,无脱落,唇侧牙龈无退缩。结论:根形植骨术是治疗上颌多颗前牙缺失伴水平向骨量不足的有效手段。Objective： To study the effects of simulated root-type bone graft onlay in the restoration of anterior maxilla bone deficiency for dental implantation. Methods： Restoration of anterior maxilla alveolar bone deficience was performed in 7 patients with 26 missing teeth by root-type bone graft, followed by dental implantation. 10 month follow-up was conducted. Results： A significant increase in the alveolar bone dimensions was achieved, labial alveolar bone presented root type. No implant was loosening or dropping, and there was no labial gingival recession. Conclusion： Root-type bone graft is effective in the restoration of anterior maxillar bone deficiency for dental implantation.
