Abstract

Aim: In advanced atrophy of the posterior maxilla, applied zygoma implants increase the success of the surgical procedure by reducing morbidity and procedure time. In our study, using tomographic records, a model with posterior atrophy was obtained in a computer environment, and zygomatic and dental implants in different numbers and localizations were applied to this model. The aim of our study was to choose the most accurate surgical planning according to the stresses arising from the applied forces. Methodology: In our study, one zygoma implant on the right and left in Group 1, two zygoma implants in Group 2, one zygoma implant in Group 3 and one dental implant in the first premolar tooth area, one zygoma implant in Group 4 and one dental implant in the lateral tooth area and one zygoma implant in Group 5 and one dental implant in the lateral and a first premolar tooth area were applied. 150 N were applied vertically to the prosthetic superstructure from the lateral tooth, 1st premolar tooth, 1st molar tooth and 2nd molar tooth. As a result of the applied forces, the maximum stress values ​​in the maxilla molar region were examined by finite element stress analysis. Results: In our study, it was observed that Group 1 had the highest stress value, followed by Group 3. Stress values in Groups 2, 4 and 5 were low and they were measured close to each other. Conclusion: As a result of our study, it was seen that zygomatic and dental implants applied in addition to the zygomatic implant reduce stress and the localization of dental implants affect the stress values.   How to cite this article: Gülsün B, Çetindağ A.

对萎缩性无牙上颌骨植体应力的检测
目的:应用颧骨种植体治疗晚期上颌骨萎缩,减少手术时间和发病率,提高手术成功率。在我们的研究中,利用断层扫描记录,在计算机环境下获得了一个后部萎缩的模型,并在该模型中应用了不同数量和定位的颧种植体和牙种植体。我们研究的目的是根据所施加的力产生的应力选择最准确的手术计划。方法:在我们的研究中,第1组左侧和右侧各种植1颗颧种植体,第2组种植2颗颧种植体,第3组种植1颗颧种植体,第1前磨牙区种植1颗牙,第4组种植1颗颧种植体,第5组种植1颗颧种植体,第1前磨牙区种植1颗牙。从侧牙、第一前磨牙、第一磨牙和第二磨牙垂直施加150 N。在受力作用下,采用有限元应力分析方法测定了上颌磨牙区域的最大应力值。结果:在我们的研究中,第1组的应激值最高,第3组次之。第2、4、5组的应力值较低,且测量值相近。结论:我们的研究发现除了颧骨种植体外,颧骨种植体和牙种植体可以减少应力,牙种植体的定位影响应力值。本文摘自:g ls n B, Çetindağ A.萎缩性无牙颌种植体对上颌骨应力的检测。国际医学杂志,2021;11(增刊1):210-5。https://doi.org/10.5577/intdentres.2021.vol11.suppl1.30语言修改:本手稿中的英语已由至少两名专业编辑检查,他们都是英语母语者。
