Abstract：
This patient series reports the outcomes of CAD/CAM prosthetic reconstructions in patients with cleft lip and palate (n = 9, aged 27 to 76) who have experienced significant failure with conventional restorative and fixed prosthodontic treatments. The objective of the protocol is to establish a functional and patient-friendly prosthetic structure for individuals with unilateral/bilateral cleft lip and palate (UCLP/BCLP) while minimising the requirement for specialised follow-up care in the cleft unit. The study data were obtained from a retrospective cohort at Helsinki University Hospital. Prosthetic reconstructions were performed using CAD/CAM bar structures by the Atlantis 2in1 system or Createch removable telescope structures, supported by four to eight maxillary dental implants. Out of the nine patients, seven experienced no complications. One prosthesis fracture occurred after 16 months due to a design error in the original framework, and one patient experienced failure of osseointegration in a dental fixture (specifically, one fixture out of the eight maxillary implants in this patient). In total, 56 implants were successfully placed. The maxillary dentition of elderly patients with cleft lip and palate often poses challenges due to periodontal and reconstructive issues. An implant-supported CAD/CAM bar with a removable telescope suprastructure offers an easily maintained and functional solution for dental rehabilitation.
摘要：
该患者系列报告了在常规修复和固定修复治疗中出现严重失败的唇腭裂患者（n=9，年龄27至76岁）的CAD/CAM假体重建的结果。该方案的目的是为单侧/双侧唇腭裂（UCLP/BCLP）患者建立功能性和患者友好的假体结构，同时最大程度地减少对left裂单元进行专业随访的需求。研究数据来自赫尔辛基大学医院的回顾性队列。假体重建是通过Atlantis2in1系统或Createch可移动望远镜结构使用CAD/CAM杆结构进行的，由四到八个上颌牙种植体支持。在九个病人中，七人没有并发症。由于原始框架的设计错误，16个月后发生了一个假体骨折，一名患者在牙科固定装置中出现骨整合失败(特别是，该患者的八个上颌植入物中的一个）。总的来说,成功放置了56个植入物。由于牙周和重建问题，老年唇腭裂患者的上颌牙列通常会带来挑战。植入物支持的CAD/CAM杆与可移动的望远镜超结构提供了一个易于维护和功能的解决方案，牙科康复。
