摘要
目的:对上颌单个前牙早期种植牙龈软组织效果进行观察和分析。方法:28例上颌单个前牙缺失患者,在缺牙后4～8周,平均(6.2±2.4)周,植入Straumann种植体28枚。其中12例患者同期进行骨移植术。种植体愈合3～7个月后行永久修复。随访时间为5～24个月(平均14个月)。此期间使用改良龈沟出血指数(modification sulcus bleedingindex,MBI)、探诊深度(probing depth,PD)、牙龈乳头指数(papilla fill index,PFI)、PES(pink esthetic score)评分对种植修复体周围软组织进行评价,同时对种植修复体及对侧同名牙牙冠高度进行测量。结果:28枚种植体留存率100%。12例MBI记分为1。PD平均值为(3.1±1.3)mm。PFI得分为"2"以上27例。PES平均得分为10.45±2.25。种植修复体牙冠平均高度为(8.3±2.2)mm(7.0～11.7 mm),与对侧同名牙牙冠高度差值平均(0.8±0.3)mm(-0.7～1.5 mm)。结论:单个前牙早期种植,牙龈软组织的近期效果令人满意。
Objective：To evaluate the esthetic outcomes of single-unit implant restorations in anterior maxilla completed with an early implant surgical placement protocol.Methods：Thirty patients with single tooth lost in anterior maxilla for 4～ 8 weeks were treated with Straumann implants.Bone grafting was performed in 12 implant sites.After the healing of 3～7 months,final prostheses were restored.The time in function was 14 months（5～24 months）.Clinical parameters including modification sulcus bleeding index（MBI）,probing depth（PD）,papilla fill index（PFI）,pink esthetic score（PES） were assessed.The height of clinical crown of implants compared with contralateral similar tooth were assessed.Results：The cumulative implant survival rate was 100% in observation period.The MBI score of 1 were observed in 12 implant sites.PD was（3.1±1.3） mm on average.27 patients had a score more than 2 according to PFI.The mean PES was（10.45±2.25）.The average height of clinical crown of implants was 8.3 mm（7.0～11.7 mm）,that was（0.8±0.3） mm longer than those of contralateral teeth.Conclusion：The results suggested that promising short-term esthetic outcomes could be achieved for early single implant placements.
