目的:应用颧种植体技术解决上颌骨骨量不足患者的种植修复难题。方法:颧种植体从后牙区牙槽嵴顶或偏腭侧植入,穿上颌窦进入颧骨,获得颧骨与上颌骨双重固位;同时在前牙区植入2至4枚常规种植体,可完成上颌无牙颌的固定修复。结果:上海交通大学医学院附属第九人民医院口腔种植科2002年开展颧种植体植入术,从2002至2012年间十年共完成35例患者,其中上颌骨严重萎缩患者11例,外胚层发育不全综合征患者9例,上颌骨缺损患者15例,共植入种植体植入173枚,其中颧种植体63枚,对患者进行了长期随访,取得了良好的效果,仅有1枚颧种植体失败。颧种植体累积5年成功率达100%,8年成功率达98%。讨论:颧种植体在上颌骨严重萎缩患者功能修复中获得了良好的长期效果,最新报道表明颧种植体十年成功率可达到95%以上,因此这一技术受到世界各地临床医生的青睐。结论:对于严重吸收的无牙颌、先天性无牙颌及上颌骨缺损重建患者,颧种植体技术是一种可靠的修复方法。其主要优点是避免了大量植骨手术,缩短了治疗周期。
Objective: To apply zygomatic implant technique to solve the problem of implant repair in patients with maxillary bone loss. Methods: The zygomatic implants were implanted from the crestal or palatal side of the alveolar ridge in the posterior teeth area, and the maxillary sinus was inserted into the zygoma to obtain double retention of zygoma and maxilla. At the same time, 2 to 4 conventional implants Body, to complete the maxillary edentulous fixed repair. Results: Department of Oral Implantation, Ninth People’s Hospital Affiliated to Shanghai Jiaotong University School of Medicine, Shanghai, 2002, zygomatic implants implantation was performed in 2002. A total of 35 patients were completed in 10 years from 2002 to 2012, including 11 patients with severe maxillary atrophy, ectoderm development 9 cases of incomplete syndrome and 15 cases of maxillary defect. A total of 173 implants were implanted, including 63 zygomatic implants. The patients were followed up for a long time and achieved good results. Only one zygomatic implant Body failure. Zygomatic implants cumulative 5-year success rate of 100%, 8-year success rate of 98%. Discussion: Zygomatic implants have demonstrated long-term long-term efficacy in functional rehabilitation of patients with severe maxillary atrophy. Recent reports indicate that the 10-year success rate of zygomatic implants can reach over 95% and is therefore favored by clinicians around the world. Conclusion: Zygomatic implant technique is a reliable method of repair for patients with severe edentulous, congenital edentulous and maxillary reconstruction. Its main advantage is to avoid a large number of bone graft surgery and shorten the treatment cycle.
