Misangulated and malpositioned implants pose a significant challenge for the prosthodontic treatment of edentulous patients. Most reports of maxillary overdenture patients have described the use of a bar to splint malaligned implants, followed by successful fabrication of the prosthesis. Few reports have discussed the use of individual abutments in such situations. This clinical report describes the successful use of spherical/ball abutments for the management of 4 malaligned implants in the edentulous maxilla for an overdenture. The rationale and technique for the use of spherical abutments for overdenture fabrication in such situations are described.
错位和位置不当的种植体给无牙颌患者的修复治疗带来了重大挑战。大多数上颌覆盖义齿患者的报告都描述了使用杆来固定排列不齐的种植体，然后成功制作了义齿。很少有报告讨论在这种情况下使用单个基台。本临床报告介绍了在无牙上颌中使用球形/球基台成功处理 4 个排列不齐的种植体的方法，以用于覆盖义齿。本文还介绍了在这种情况下使用球形基台制作覆盖义齿的原理和技术。
