目的:观察研究微创种植技术修复老年人游离端缺失的临床效果。方法:选取需行种植义齿修复后牙牙列游离端缺失的老年患者71例,男45例,女26例,年龄60~82岁。所有患者术前均行CBCT扫描评估,并采用微创种植修复,共植入92颗种植体。记录手术耗时、术后疼痛反应、术后出血、肿胀及种植手术成功率,并进行6~24个月的随访观察以评价其临床疗效。结果:71例老年患者采用微创种植技术,种植体植入体位置良好,未产生种植手术中常见的上颌窦底粘膜穿孔,下颌神经损伤等并发症。92枚种植体修复义齿随访6~24个月,除1例种植体周围粘膜炎,1例修复体桥体折裂,5例食物嵌塞,其余种植体修复义齿情况良好。结论:采用微创种植技术修复老年人游后牙游离端缺失,手术并发症少,修复成功率高,值得临床推广应用。
OBJECTIVE: To observe the clinical effect of minimally invasive implantation technique in repair of free end deletion in the elderly. Methods: A total of 71 elderly patients with missing dentition dentition were selected, including 45 males and 26 females, aged 60-82 years. All patients underwent CBCT scan assessment before surgery, and minimally invasive implant repair, a total of 92 implants implanted. Time-consuming surgery, postoperative pain response, postoperative bleeding, swelling and implantation success rate were recorded and followed up for 6 to 24 months to evaluate the clinical efficacy. Results: Seventy-one elderly patients underwent minimally invasive implantation. The implants were well placed and did not cause complications such as perforation of maxillary sinus mucosa and injury of mandibular nerve. Ninety-two implant prostheses were followed up for 6 to 24 months. Except for 1 case of peri-implant mucositis, 1 case of bridge prosthesis was fractured and 5 cases of food impaction. The remaining implant prosthesis was in good condition. Conclusion: The technique of minimally invasive implantation for the repair of elderly patients with posterior teeth free end missing, fewer complications, high repair success rate, worthy of clinical application.
