The objective was to describe the use of a maxillary obturator supported by dental implants and ball abutments in an adult edentulous unilateral cleft patient. Adult edentulous cleft patients who have had no corrective surgeries or failed attempts at cleft repair in childhood suffer from oronasal communication resulting in hypernasal speech, dysphagia, and compromised masticatory ability. Tissue-supported obturator prostheses in such patients provide for compromised function due to instability and lack of retention. The treatment using fibromucosal-supported obturators is well established in the literature; few articles have also described osseointegrated implants supporting the prosthesis in adult cleft patients supported by bar attachments and magnets; however, reports of implant-supported maxillary obturators retained by ball/stud attachments are scarce. The implants provided retention and stability to the prosthesis, simplifying the laboratory procedure using ball abutments, improving swallowing, speech, and the patient's general quality of life. This article reports the rehabilitation of an adult cleft palate patient with a totally edentulous maxilla using an implant-retained prosthesis.
目的是描述在一名成年单侧唇腭裂无牙患者中使用由牙种植体和球帽基台支持的上颌阻塞器的情况。成年单侧唇腭裂无牙患者若在儿童期未接受过矫正手术或腭裂修复尝试失败,会出现口鼻相通,导致鼻音过重、吞咽困难和咀嚼能力受损。此类患者使用组织支持式阻塞器假体时,由于稳定性和固位性不足,功能会受到影响。文献中已充分确立了使用纤维黏膜支持式阻塞器的治疗方法;也有少数文章描述了在成年腭裂患者中使用杆附着体和磁体支持假体的骨结合种植体;然而,关于球/柱附着体固位的种植体支持上颌阻塞器的报道却很少。种植体为假体提供了固位和稳定性,简化了使用球帽基台的实验室操作,改善了吞咽、语音和患者的总体生活质量。本文报道了一名成年腭裂患者全上颌无牙使用种植体固位假体的修复情况。
