The fully edentulous mandible presents functional, esthetic, and psychological challenges for the patient and the dentist. The mandibular overdenture supported by endosseous implants can provide a superior treatment modality, overcoming many of the difficulties inherent in the conventional denture. Advantages cited are increased denture retention, improved chewing efficiency, maintenance of bone height, replacement of lost anatomy, increased denture stability, reduction of soft tissue coverage and extension of the prosthesis, and easy access for hygiene maintenance. The major disadvantage rests with the patient's intolerance of a removable prosthetic design.
无牙颌下颌骨给患者和牙医带来了功能、美观和心理方面的挑战。由骨内种植体支持的下颌覆盖义齿可以提供一种更优的治疗方式，克服传统义齿固有的许多困难。其优点包括义齿固位力增强、咀嚼效率提高、骨高度维持、缺失解剖结构的替代、义齿稳定性增加、软组织覆盖减少和义齿延伸、以及易于进行卫生维护。主要缺点在于患者对可摘修复设计的不耐受。
