Adult patients with bilateral cleft lip and palate present unique challenges for prosthodontic treatment because of mobility of the premaxillary segment, oral-nasal communication, multiple missing and malpositioned anterior teeth, unfavorable soft tissues, and scar tissue underneath the maxillary lip. This clinical report describes the prosthodontic treatment of an adult patient with a terminal maxillary dentition and bilateral cleft palate, by using 5 dental implants and a 1-piece complete-arch fixed implant-supported prosthesis made of monolithic zirconia. The zirconia prosthesis aided in rigidly splinting not only the implants but also in orthopedically splinting the mobile premaxillary segment to the maxilla. Additional surgical and prosthodontic considerations in splinting the mobile premaxilla as well as biomechanical principles involved in management of such patients are also presented in this article.

由于前上颌骨段的活动性、口鼻沟通、多颗缺失和错位的前牙、不利的软组织以及上颌唇下方的疤痕组织，双侧唇裂和腭裂的成年患者对修复治疗提出了独特的挑战。本临床报告描述了使用 5 个牙种植体和由整体氧化锆制成的 1 件式完整牙弓固定种植体支撑修复体对具有上颌末端牙列和双侧腭裂的成人患者进行的修复治疗。氧化锆假体不仅有助于将植入物牢固地夹板固定，还有助于将可移动的上颌骨前段与上颌骨进行矫形夹板固定。
