应用半环形导板引导缺牙区近远中间隙狭窄的患者种植手术9例报告

Application of LeaderguidTM template in implant surgery for patients with narrow mesiodistal space in the edentulous area:report of 9 cases

为了探讨一种新型改良种植手术导板半环形导板在引导近远中间隙狭窄患者种植手术的应用,为临床治疗提供参考,本研究对9例单颗牙缺失,窄近远中间隙,近远中方向骨量不足患者应用半环形导板进行种植手术,通过测量术后种植体与近远中邻牙距离评估该导板应用的准确性。种植后9例患者手术均取得了良好的效果。术后所有患者的种植体与近中邻牙的平均距离为(1.66±0.10)mm,与远中邻牙的平均距离为(1.66±0.12)mm,均大于1.5 mm的安全推荐值,且随访期间无种植失败及术后并发症的发生。本病例系列研究表明,半环形导板可有效地辅助缺牙区近远中方向狭窄患者的种植体植入,并且省时、安全、易于口腔科医生临床操作。

Objective To explore the application of a new improved LeaderguideTM template in implant surgery for patients with narrow mesiodistal space,and to provide a reference for clinical treatment.Methods Nine patients with single tooth loss,narrow mesiodistal space,and insufficient bone quantity in the mesiodistal direction of the edentulous site were implanted with the LeaderguideTM template.The accuracy of the template was evaluated by measuring the distance between the implant and the mesiodistal adjacent teeth after surgery.Results The use of the LeaderguideTM template for implant surgery achieved good results.The average distance between implants and the mesial adjacent teeth of all patients after the operation was(1.66±0.10)mm,and the average distance between implants and the distal adjacent teeth was(1.66±0.12)mm.The mesial and distal distances were all larger than the safety recommendation of 1.5 mm.And there was no implant failure and postoperative complications occurred during the follow-up period.Conclusion This case series shows that the LeaderguideTM template can effectively assist in placing implants in patients with narrow mesio-distal space in the edentulous area.
