不翻瓣技术在上颌前牙区种植中的应用效果

Implants in anterior maxilla with flapless technique

目的探讨不翻瓣技术在上颌前牙区种植中的应用效果。方法选取2018年4-10月在武警北京总队医院进行上颌前牙区种植的32例患者,随机分为不翻瓣组(采用不翻瓣技术种植)和翻瓣组(采用翻瓣技术),每组16例。比较两组手术情况和种植手术后的效果;种植后3和6个月进行随访,比较种植体周围牙槽骨骨吸收程度。结果不翻瓣组的手术时间(18.87±4.34)min,翻瓣组的手术时间为(37.27±5.35)min,两组差异有统计学意义(P<0.05);不翻瓣组的术后肿痛时间和抗生素应用时间分别为(0.85±0.33)d和(1.84±0.75)d,翻瓣组的术后肿痛时间和抗生素应用时间分别为(2.61±0.74)d和(4.22±1.36)d,两组对比差异均有统计学意义(P<0.05)。不翻瓣组种植后3个月和6个月时的种植体周围牙槽骨吸收分别为(0.29±0.05)mm和(0.36±0.07)mm,翻瓣组种植后3个月和6个月分别为(0.55±0.06)mm和(0.65±0.05)mm,两组差异有统计学意义(P<0.05)。结论口腔种植采用不翻瓣技术,能缩短手术时间和手术后肿痛时间,减少抗生素使用,降低牙槽骨吸收。

Objective To evaluate the clinical effects of implantation performed with the flapless technique in anterior maxilla.Methods Thirty-two patients scheduled for implants in anterior maxilla in Beijing Municipal Corps Hospital between April 2018 and October 2018 were divided into two groups:the flapless technique group(n=16)and the flap technique group(n=16).The duration of surgery in the two groups was calculated and clinical effects were observed.Follow-up started 3 months and 6 months after implantation.Alveolar bone resorption around the implants was recorded and compared via X-ray.Results The duration of surgery in the flapless technique group was(18.87±4.34)minutes,compared with(37.27±5.35)minutes in the flap technique group,with statistically significant difference(P<0.05).The postoperative duration of oral swelling and pain and that of antibiotic use in the flapless technique group were(0.85±0.33)days and(1.84±0.75)days respectively,compared with(2.61±0.74)days and(4.22±1.36)days respectively in the flap technique group,so the difference was of statistical significance(P<0.05).The time taken by alveolar bone resorptions 3 months and 6 months after implantation was(0.29±0.05)mm and(0.36±0.07)mm respectively in the flapless technique group and(0.55±0.06)mm and(0.65±0.05)mm respectively in the flap technique,so the difference was also of statistical significance(P<0.05).Conclusions The flapless technique used in implantation can shorten the duration of surgery and oral swelling and pain,reduce the use of antibiotics and decrease bone resorption around implants.
