The maxilla is a challenging area for dental implant restoration. Encroachment of anatomic structures such as the sinus and nasal floor make vertical placement difficult. Implants placed at an angle may be used to avoid these anatomic structures or eliminate the need for a bone grafting procedure. The question occasionally arises about the possible detrimental effects of placing implants at an angle. This article reviews relevant literature, presents two case reports on maxillary angled implants and presents 3 years of data on 276 All-on-Four restorations.
上颌骨是牙种植修复的一个具有挑战性的区域。鼻窦和鼻底等解剖结构的侵占使得垂直植入变得困难。以一定角度植入种植体可用于避开这些解剖结构或避免进行骨移植手术。偶尔会出现关于以一定角度植入种植体可能产生的有害影响的问题。本文回顾了相关文献，介绍了两例上颌骨倾斜种植体的病例报告，并展示了276例All-on-Four修复体的3年数据。
