Objective: To investigate the clinical effect of guided bone regeneration technique in dental im-plant restoration of oral and maxillofacial trauma tooth loss and bone defects. Methods: 63 patients with maxillary anterior teeth were selected from March 2014 to April 2015 and were randomly divided into treatment group(33 cases) and control group(30 cases). Ccontrol group used maxillary anterior teeth of the second phase of the planting method, but not for the recovery of bone mass, treatment group with GBR technique for dental implant in the anterior maxilla and dental implant fixation after implantation of artificial bone. On the day after operation, 6 months and 12 months after implantation, the red aes-thetic parameters of soft tissue and the level of bone around the implant were compared between the two groups. Results: Compared with the baseline level, the two groups of patients with dental implants for 6 months, 12 months of red aesthetic index values were significantly increased (P<0.05), the differ-ence between the two groups was not statistically significant (P>0.05). Implant weightbearing 12 months later, baseline and compared in addition to alveolar shape and lip side gingival margin level two index-es had no significant difference, other red aesthetic parameters in the two groups were improved signifi-cantly(P<0.05), and there was no statistical significance between the two groups (P>0.05). Conclusion:GBR can effectively deal with traumatic occlusal damage with bone tissue in patients with impaired chewing ability and the language, is conducive to the appearance of the restoration, and has damage to the remaining teeth small, in oral and maxillofacial trauma and loss of posterior teeth with bone defect in the treatment effect and prospect are better.%目的：探讨引导骨组织再生技术种植修复口腔颌面部创伤后牙缺失伴骨缺损的临床效果。方法：选取2014年3月~2015年4月在本院诊治的口腔颌面部上颌前牙缺失患者63例，随机分为治疗组（33例）和对照组（30例）。对照组运用上前牙二期种植方法，但是没有进行骨量恢复，治疗组采用GBR技术进行上颌前牙种植，待人工牙根固定后植入人工骨粉。分别于术后当日、种植牙负重6个月及12个月对两组患者软组织红色美学参数及种植体周围骨水平进行比较分析。结果：与基线水平比较，两组病例种植牙负重6个月、12个月红色美学指数值均显著上升（P<0.05），比较两组之间的差异无统计学意义（P>0.05）。种植牙负重12个月后，与基线水平比较，除了牙槽突外形和唇侧龈缘水平两项指标无明显差异，两组病例其它红色美学参数各项指标均显著提升（P<0.05）；而两组间各项指标水平比较无统计学意义（P>0.05）。结论： GBR术能够有效地处理创伤性牙损坏合并骨组织受损患者的咀嚼及语言能力，有利于外貌的恢复，且具有对余留牙损害小的特点，在口腔颌面部创伤后牙缺失伴骨缺损治疗中效果和前景均较好。
