Edentulous patients may be restored with complete-arch implant-supported fixed complete dental prostheses (IFCDPs) on angled distal implants or on parallel implants distributed equally across the mandible to increase the area of support. A treatment is presented to introduce the clinical concept of providing edentulous patients with an implant-supported fixed complete dental prosthesison parallel tissue-level implants in the mandible with standard length implants interforaminally and ultrashort implants distally. A structured prosthetic approach was used for the tooth arrangement with a modified workflow as per the Biofunctional Prosthetic System adapted for static computer-aided implant surgery (s-CAIS) and computer-aided design and computer-aided manufacturing (CAD-CAM) of the screw-retained implant-supported fixed complete dental prosthesis. The concept offered advantages in challenging anatomic, surgical, and prosthetic conditions; providing distal nonangled abutments and implant platforms, which were straightforward to clean. If necessary, the prosthesis could have been easily converted into a removable overdenture using the existing digital prosthetic arrangement. Should implant removal be required, the extrashort implants can be removed with minimal surgical risk or morbidity.

无牙颌患者可以在成角度的远端种植体上或在下颌骨上均匀分布的平行种植体上使用全牙弓种植体支撑的固定式完整义齿修复体 (IFCDP) 进行修复，以增加支撑面积。提出了一种治疗方法来介绍临床概念，即为无牙牙患者提供下颌骨内种植体支持的固定式完整假牙平行组织水平种植体，在椎间孔内种植标准长度种植体，在远端种植超短种植体。根据适用于静态计算机辅助种植手术 (s-CAIS) 和计算机辅助设计和计算机辅助制造 (CAD-CAM) 的生物功能修复系统，使用结构化修复方法进行牙齿排列，并修改了工作流程。螺钉固位种植体支撑固定完整假牙。该概念在具有挑战性的解剖、手术和修复条件方面具有优势；提供易于清洁的远端无角基台和种植体平台。如有必要，使用现有的数字义齿装置可以轻松地将义齿转换为可摘覆盖义齿。如果需要移除种植体，可以以最小的手术风险或发病率移除超短种植体。
