Ankylos种植系统多牙固定修复短期临床疗效评价

A short-term clinical evaluation of effectiveness of the fixed implantation of Ankylos implant system with multiple crowns

目的评价Ankylos种植体用于固定修复多牙缺失的临床应用效果。方法临床选择21例多牙缺失患者完成An-kylos 68枚种植体进行潜入式种植手术,部分骨量不足的患者,同期使用膜引导骨再生术、上颌窦内提升术或上颌窦外提升术。Ⅱ期手术两周后,按照常规方法完成金钯合金烤瓷冠修复。术后随访,检查修复体与基台的稳定性,种植体周围牙龈组织的健康状况;通过X线检查观察骨组织的吸收情况及基台的密合程度;调查患者对种植义齿咀嚼、美观功能的主观满意度。种植后及义齿修复后的临床观察期为1～2.5年。结果冠桥修复后,1例患者的1枚种植体在种植修复后1个月时,发生种植体周围炎;1例在修复后1年烤瓷冠崩瓷;其余种植体均稳定,无明显骨吸收,种植体基台界面密合,牙龈组织健康。按种植成功标准,修复成功66枚,成功率97.1%;失败2枚,占2.9%。结论 Ankylos种植体用于多牙缺失的固定修复具有良好的临床效果。

Objective To evaluate the clinical effects of Ankylos implant system to restore the loss of more than one teeth.Methods Totally,21 cases with loss of more than one teeth were investigated,and a total of 68 implants were placed from January,2008 to May,2010.All the patients had undergone routinely two-stage surgery.When patients showed deficient alveolar ridge,guided bone regeneration（GBR）,osteotome sinus floor elevation,lateral antrostomy surgery with simultaneous placement of implants were applied.They were restored with platinum ceramic crowns.All implants were followed up,and records were kept about stability of the implants and abutments,conditions of the surrounding soft tissues,sealability of implant abutment junction,the marginal bone loss through X-ray checking,satisfaction of the patients to mastication,and other aspects of the restorations.The follow-up time was 1～2.5 years.Results Among all of the cases,one case had peri-implant inflammation,and one case’s porcelain dropped.No loosening occurred to the other implants and abuments.Implant abutment junction was sealed well.The marginal bone loss 1 year after final restoration was less than 1mm.Soft tissue surrounding implants was healthy.According to standard of implantation success,66 implants were successful,the cumulative success rate was 97.1%;2 cases failed,and the failure rate was 2.2%.Conclusions Satisfactory treatment effects could be got by using Ankylos implant system to restore the loss of multi-teeth.
