即刻种植和早期种植对前牙美学区种植体周围软组织的影响分析

目的:分析即刻种植和早期种植对前牙美学区种植体周边软组织的影响。方法:随机抽取我院于2015年8月至2019年8月期间收治的60例单颗前牙缺失患者,其中有30例患者于拔牙后行即刻种植(观察组),30例拔牙后行早期植入(对照组),均予以Astra Tech种植体及种植体植入半年后给予氧化锆全瓷修复,并在半年后复查,对比分析两组患者的红色美学评分(PES)等。结果:两组患者对比PES总分和各节点PES评分无明显差异(P>0.05)而在各节点PES评分中,牙龈生物型和牙槽骨缺损、远中龈乳头,缺失牙位和牙龈高度及缺牙原因和近、远中龈高度存在显著相关性。结论:即刻种植和早期种植对前牙美学区种植体周边软组织之间的影响差异不明显,对前牙美学区种植体修复时软组织美学产生的主要影响包括缺失牙位、牙龈生物型及缺牙原因。

Analysis of the effects of immediate planting and early planting on the soft tissue around the implant in the esthetic area

Objective:To analyze the effects of immediate planting and early planting on the soft tissues around the implants in the edentulous aesthetic area.Methods:A total of 60 patients with single anterior teeth loss from August 2015 to August 2019 were randomly selected.Among them,30 patients were implanted immediately after tooth extraction(observation group),and 30 patients were implanted early after tooth extraction.Into the control group,the zirconia all-ceramic restoration was given to the Astra Tech implants and implants six months later,and the results were reviewed after half a year.The red aesthetic scores(PES)of the two groups were compared.Results:There was no significant difference between the two groups in the PES score and the PES scores of each node(P>0.05).In the PES scores of each node,the gingival biotype and alveolar bone defect,the distal nipple,the missing tooth position and the gingival height and there is a significant correlation between the cause of missing teeth and the height of near and far.Conclusion:The effects of immediate implantation and early implantation on the soft tissue around the implant in the edentulous aesthetic area are not obvious.The main effects of soft tissue aesthetics on implant restoration in the anterior aesthetic area include missing tooth position,gingival biotype and lack of teeth.
