摘要
目的:探讨即刻骨移植与延期牙种植术联合应用修复外伤性上颌前牙区唇侧牙槽骨及牙列缺损的效果。方法:选择16例因各种外伤引起的上颌前牙区牙槽骨唇侧部分缺损及部分上前牙缺失患者,在清创缝合伤口的同时,切取大小合适的自体颅骨外板或颏部骨板,移植到骨缺损部位,钛钉固定,严密缝合牙龈及黏骨膜组织,并在12周后植入ITISLA种植体42颗。种植体植入后12周,用金属烤瓷牙做固定修复。另选22例患者共50颗采用标准种植手术且无需植骨的ITISLA种植体作为对照组,于种植体植入后不同时间点,采用无线共振频率分析仪测定2组患者的种植体稳定值(ISQ),应用SPSS13.0软件包对实验组与对照组的ISQ值进行配对t检验。结果:16例患者软组织伤口均一期愈合,黏膜及牙龈组织形态良好,牙槽骨丰满,牙槽弓弧度满意,义齿修复后形态及功能良好。2组种植体在0、4、12、52周时ISQ均值差异比较,其P值分别为为0.82、0.85、0.96和0.89。结论:外伤引起的上颌前牙区牙槽骨唇侧部分缺损,在清创缝合伤口的同期进行自体骨移植,再延期采用种植义齿修复,可以缩短疗程,减少手术次数,获得良好的修复效果。
PURPOSE： The purpose of this study is to evaluate immediate autologous bone graft combined with secondary dental implant to repair traumatogenic defect and lost teeth. METHODS： 16 patients with labial anterior maxillary alveolar bone defect, caused by trauma for various reasons were selected as the experimental group. The suitahle size autologous skull plates or chin hone plates were harvested and transplanted to the hone defect site and fixed with titanium screw immediately after the wound was completely cleaned, and then the gingiva and mucosa were sutured adequately. 42 ITI SLA implants were implanted 12 weeks after bone graft surgery. Porcelain fused metal crowns were made 12 weeks after implantation. Meanwhile, a total of 22 patients with 50 ITI SLA implants which were routinely implanted in anterior maxillary alveolar bone without bone graft surgery were selected as the control group. Resonance frequency analysis（RFA） was taken at 0,4,12,52 weeks after implant surgery in both groups to get implant stability quotient（ISQ） values. Student＇s t test was used to calculate P values for ISQ with SPSS13.0 software paekage. RESULTS： The soft tissue wound of 16 patients healed 7-9 days after trauma. The alveolar arch returned normal, the alveolar ridge was with adequate height and width. The contour and function of dentures restored 12 weeks after implantation. No significant difference in ISQ values was found between the two groups at 0,4,12.52 weeks after implant surget~~ （/%0.05）. CONCLUSIONS： The course of treatment is shortened, the times of surgery are reduced, and the repair effect is satisfied by immediate autologous bone graft and secondary dental implantation for upper anterior labial alveolar bone defect and teeth loss caused by trauma.
