牙根留置技术在上颌前牙区延期种植的效果及对红色美学指数的影响

Effect of Root Retention Technique on the Red Esthetics Index of Delayed Maxillary Anterior Dental Implant

目的:探讨牙根留置技术在上颌前牙区延期种植中的应用效果及对红色美学指数的影响。方法:选取2019年5月-2022年4月在笔者医院口腔科就诊的上颌前牙区需种植修复的86例患者为研究对象,根据种植时间的不同将患者分为对照组(即刻种植)和观察组(延期种植),每组43例。修复后即刻与修复后6个月,评估两组患者各个位点牙槽嵴宽度、改良菌斑指数(Modified plaque index,mPI)、改良出血指数(Modified sulcus bleeding index,mSBI)及红色美学指数评分(Pink esthetic score,PES);修复后6个月,评估两组患者并发症发生率及满意程度。结果:与修复后即刻比较,对照组患者修复后6个月各个位点的牙槽嵴宽度均减小,差异有统计学意义(P<0.05);修复后6个月,两组患者mPI与mSBI较修复后即刻均明显降低(P<0.05);修复后6个月组间比较差异有统计学意义(P<0.05),观察组患者mPI与mSBI均低于对照组;修复后6个月,两组患者PES各项评分及总分均高于修复后即刻,且观察组PES各项评分及总分均高于对照组(P<0.05);对照组发现桥体位置1例牙龈炎,观察组未发现任何并发症,差异无统计学意义(P>0.05);观察组患者色泽、附着高度、咀嚼功能及整体美观度评分均高于对照组(P<0.05)。结论:牙根留置技术在上颌前牙区延期种植中可改善患者术后修复效果,提高牙齿的美观度,患者满意度较高。

Objective To The effect of root retention technique on the pink esthetic score(PES)and its application in delayed maxillary anterior dental implant.Methods From May 2019 to April 2022,86 patients with maxillary anterior teeth in the author’s hospital were selected,patients were divided into control group(immediate implantation)and observation group(delayed implantation)according to the different time of implantation,43 cases in each group.The width of alveolar ridge,modified plaque index(mPI),modified Bleeding Index(mSBI)and PES were evaluated immediately and 6 months after restoration.Complications and satisfaction were assessed at 6 months after repair.Results The width of alveolar ridge in the control group was significantly decreased 6 months after restoration compared with that immediately after restoration(P<0.05),and the width of alveolar ridge at each site decreased in the control group mPI and mSBI were significantly lower in both groups at 6 months after repair than at the moment after repair(P<0.05),and there was a significant difference between the two groups at 6 months after repair(P<0.05),mPI and mSBI in the observation group were lower than those in the control group,and PES scores and total scores in the observation group were higher than those in the control group at 6 months after repair,the PES scores and total scores of the two groups at 6 months after restoration were significantly higher than those immediately after restoration(P<0.05),while one case of gingivitis in bridge position was found in the control group,and no complication was found in the observation group,there was no significant difference(P>0.05),and the scores of color,attachment height,masticatory function and overall esthetics in the observation group were higher than those in the control group(P<0.05).Conclusion The technique of tooth root retention can improve the effect of restoration,improve the appearance of teeth and the satisfaction of patients.
