可吸收胶原蛋白线在口腔种植修复术切口无张力缝合中的应用价值

目的:比较可吸收胶原蛋白线与丝线编织非吸收性缝线在口腔种植修复手术切口无张力缝合中的临床效果及对患者伤口愈合时间的影响。方法:选取2016年8月-2017年8月在笔者医院门诊行牙齿种植修复术的188例患者为研究对象,采用随机数字法将其分为试验组和对照组,每组94例。试验组采用可吸收胶原蛋白线缝合伤口,对照组采用丝线编织非吸收性缝线缝合伤口。比较两组患者伤口愈合等级、平整率、缝合线完全吸收率、切口愈合时间、疼痛情况及不良反应发生情况。结果:试验组:甲级愈合89例,乙级愈合5例;对照组:甲级愈合74例,乙级愈合19例,丙级愈合1例,试验组患者伤口愈合等级显著优于对照组,差异有统计学意义(P<0.05)。试验组患者牙龈红肿5例,对照组患者牙龈红肿16例,渗血10例,试验组患者牙龈红肿、渗血及总发生情况均显著优于对照组,差异有统计学意义(P<0.05)。术后3、5、7d,试验组患者缝线位点完全吸收率分别为0.00%、11.35%、97.52%,对照组患者缝线位点完全吸收率均为0.00%,试验组患者缝线位点完全吸收率在术后3、5d均显著高于对照组,差异均具有统计学意义(P<0.05)。试验组患者切口平整率为85.11%,对照组患者切口平整率为68.09%,差异具有统计学意义(P<0.05)。试验组患者伤口愈合时间为(5.23±0.31)d,对照组患者伤口愈合时间为(7.57±0.36)d,试验组患者伤口愈合时间显著优于对照组,差异有统计学意义(P<0.05)。术后3、5、7d,试验组患者VAS评分分别为(3.17±1.65)分、(2.04±0.88)分、(1.11±0.56)分,对照组患者VAS评分分别为(4.97±1.74)分、(3.74±1.25)分、(2.73±0.93)分,在各个时间节点,试验组患者VAS评分水平均显著优于对照组,差异有统计学意义(P<0.05)。结论:可吸收胶原蛋白线在口腔种植修复手术切口无张力缝合中的临床效果较丝线编织非吸收性缝线的临床效果更加显著,应用可吸收胶原蛋白缝线能够有效提高患者伤口愈合效果、缩短愈合时间,同时减少不良反应,值得在临床推广应用。

Application Value of Absorbable Collagen Thread in Tension-free Suture of Oral Implant Prosthetic Incision

Objective To compare the clinical effects of absorbable collagen thread and silk-woven non-absorbable suture in tension-free suture of oral implant restoration and its effect on wound healing time.Methods A total of 188 patients who underwent dental implant restoration in our hospital from August 2016 to August 2017 were randomly divided into experimental group and routine group,with 94 cases in each group.The experimental group sutured the wound with an absorbable collagen thread,and the conventional group sutured the wound with a silk-woven non-absorbable suture.The wound healing grade,flatness rate,complete suture absorption rate,wound healing time,pain and adverse reactions were compared between the two groups.Results In the experimental group,89 patients had grade A healing,5 patients had grade B healing,74 patients had grade A healing,19 patients had grade B healing,and 1 had grade C healing.The wound healing grade of the experimental group was significantly better than that of the conventional group.The difference was statistically significant (P<0.05).In the experimental group,5 cases of gingival redness and swelling,16 cases of gingival redness and swelling,and 10 cases of oozing in the routine group.The gingival redness,oozing and total incidence of the test group were significantly better than the conventional group,the difference was statistically significant (P<0.05).At 3,5,and 7 days after operation,the complete absorption rates of suture sites in the experimental group were 0.00%,11.35%,and 97.52%,respectively.The complete absorption rate of the points was 0.00%.The complete absorption rate of suture micro-shops in the experimental group was significantly higher than that in the control group at 3 and 5 days after operation,and the difference was statistically significant (P<0.05).The incision flatness rate of the experimental group was 85.11%,and the incision flatness rate of the control group was 68.09%.The difference was statistically significant (P<0.05).The wound healing time of the experimental group was (5.23±0.31) days,and the wound healing time of the routine group was (7.57±0.36) days.The wound healing time of the experimental group was significantly better than that of the conventional group,the difference was statistically significant (P<0.05).At 3,5,and 7 days after operation,the VAS scores of the experimental group were (3.17±1.65),(2.04±0.88),and (1.11±0.56),respectively.The VAS scores of the routine group were (4.97±1.74),(3.74±1.25) points,(2.73±0.93) points,the VAS scores of the test group were significantly better than those of the conventional group at each time point,and the difference was statistically significant (P<0.05).Conclusion The clinical effect of absorbable collagen thread suture in the tension-free suture of oral implant repair surgery is more significant than that of silk-woven non-absorbent suture.The application of absorbable collagen suture can effectively improve the wound healing effect,shorten the healing time,and reduce the adverse reactions,which is worthy of clinical promotion.
