引导骨再生术在前牙区种植中的应用及对美学效果和临床疗效的影响

Application of Guided Bone Regeneration in Anterior Dental Implants and Its Effect on Aesthetics and Clinical Efficacy

目的:探讨前牙区种植联合引导骨再生术的临床应用价值。方法:选取2022年1月-2022年10月笔者医院接受前牙区种植的142例患者,采用随机数字法将患者分为对照组(n=70)和观察组(n=72)。对照组单纯进行牙种植,观察组在牙种植基础上联合引导骨再生术治疗。通过临床资料收集比较两组治疗前和治疗6个月后的牙槽骨密度、植骨厚度和成骨厚度、牙周探诊深度(Periodontal depth,PD)、临床附着丧失(Clinical attachment loss,CAL)、牙龈退缩(Gingival recession,GR)、红色美学指数(Pink esthetic scores,PES)、临床疗效和并发症。结果:术后6个月,两组牙槽骨密度、植骨厚度和成骨厚度均高于术前,且观察组高于对照组(均P<0.05);术后6个月,两组PD、CAL及GR均低于术前,且观察组PD、CA及GR均低于对照组(P<0.05);术后6个月,两组PES指标评分均高于术前,且观察组高于对照组(P<0.05)。观察组总有效率95.83%,高于对照组的91.43%(P<0.05);观察组并发症发生率1.39%,低于对照组的8.57%(P<0.05)。结论:前牙区种植联合引导骨再生术美学效果好、PES评分高,临床总有效率高且并发症发生率低,具有较高的临床应用价值。

Objective To investigate the clinical application value of combined guided bone regeneration during anterior dental implantation.Methods A total of 142 patients who received anterior dental implants in the author's hospital from January 2022 to October 2022 were selected and divided into control group(n=70)and observation group(n=72)by random number method.The control group was treated with dental implant alone,and the observation group was treated with guided bone regeneration based on dental implant.Alveolar bone density,graft thickness and osteogenic thickness,periodontal depth(PD),clinical attachment loss(CAL),gingival recession(GR),pink esthetic scores(PES),clinical efficacy and complications were compared between the two groups before treatment and 6 months after treatment.Results The alveolar bone density,bone graft thickness and osteogenic thickness at 6 months after surgery were higher in 2 groups than before surgery.The alveolar bone density,bone graft thickness and osteogenic thickness of the observation group were higher than those of the control group 6 months after surgery,with statistical differences(P<0.05).6 months after surgery,PD,CAL and GR in 2 groups were lower than before surgery.6 months after surgery,PD,CA and GR in the observation group were lower than those in the control group,with statistical differences(P<0.05).The PES index score of 2 groups after 6 months surgery was higher than that before surgery,and the PES index score of observation group was higher than that of control group 6 months after surgery,with statistical difference(P<0.05).The total effective rate of the observation group was 95.83%,higher than that of the control group 91.43%,and the complication rate was 1.39%,lower than that of the control group 8.57%(P<0.05).Conclusion Anterior dental implant combined with guided bone regeneration has good aesthetic effect,high PES score,high clinical total effective rate and low complication rate,which has high clinical application value.
